Barriers to Alzheimer Disease Clinical Trial Participation in a Minority Population.

BACKGROUND: Alzheimer disease (AD), the most common neurodegenerative disorder in the United States, disproportionately burdens minority populations. OBJECTIVE: To explore barriers to AD clinical trial participation by Asian and Native Hawaiian patients diagnosed with AD or mild cognitive impairment. METHOD: We surveyed 187 patients with a Mini-Mental State Examination score ≥14 between January 2022 and June 2022. The score cutoff for clinical trial eligibility was set by the institution. Individuals also completed a 15-question telephone survey that assessed demographics, barriers to clinical trial participation, and clinical trial improvement methods. RESULTS: Forty-nine patients responded, with a response rate of 26%. Asian and Native Hawaiian patients were less likely than White patients to participate in AD trials. The main barrier to participation was a lack of information about AD trials. Providing additional information regarding AD trials to patients and family members were listed as the top two reasons patients would consider participating in a clinical trial. CONCLUSION: Insufficient information about AD clinical trials is the primary barrier to participation among Asian and Native Hawaiian patients, followed by difficulty coordinating transportation and, in the case of Asians, the time required for clinical trials. Increased outreach, education, and assistance with logistics in these populations should be pursued to improve rates of participation in clinical trials.

Abnormal Temporal Slowing on EEG Findings in Preclinical Alzheimer's Disease Patients With the ApoE4 Allele: A Pilot Study.

INTRODUCTION: Currently, there are limited accessible and cost-effective biomarkers for preclinical Alzheimer's disease (AD) patients. However, the apolipoprotein E (ApoE) polymorphic alleles can predict if someone is at high (e4), neutral (e3), or low (e2) genetic risk for developing AD. This study analyzed electroencephalogram (EEG) reports from individuals with various ApoE genotypes, aiming to identify EEG changes and patterns that could potentially serve as predictive markers for preclinical AD progression. METHODS: Participants aged 64-78 were selected from the patient database at an outpatient neurology clinic. Genotype studies were performed to determine ApoE status, followed by EEG analysis to identify any apparent trends. A case-control design was used, categorizing participants into cases (e2e3, e2e4, e3e4, e4e4) and controls (e3e3). EEG recordings were compared between the groups to identify potential differences in EEG characteristics, including abnormal temporal slowing, frequency, and ApoE genotype association. RESULTS: Among 43 participants, 49% demonstrated evidence of abnormal temporal slowing on EEG. Of these, 48% displayed focal left temporal slowing, and 52% displayed bilateral temporal slowing. The right-sided temporal slowing was not observed. Among participants with abnormal slowing, 95% exhibited theta frequency (4-8 Hz) slowing, while only 4.8% displayed delta frequency (0-4 Hz) slowing. Among participants with the ApoE4 allele, 61.5% demonstrated evidence of abnormal slowing, compared to 43.3% without it. Furthermore, the presence of an ApoE4 allele was associated with a significantly higher proportion of males (54%) compared to those without it (13%) (p=0.009). CONCLUSIONS: Although we did not find a statistically significant difference in temporal EEG slowing among different ApoE genotypes, our findings suggest a potential association between temporal slowing on EEG and the presence of an ApoE4 allele in individuals with preclinical AD. These observations highlight the need for further exploration into the potential influence of the ApoE4 allele on EEG findings and the utility of EEG as a complementary diagnostic tool for AD. Longitudinal studies with large sample sizes are needed to establish the precise relationship between EEG patterns, ApoE genotypes, and AD progression.

Mechanisms and Severity of Exercise Intolerance Following COVID-19 and Similar Viral Infections: A Comparative Review.

Approximately 19% of the population is suffering from "Long COVID", also known as post-acute sequelae of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (PASC), which often results in exercise intolerance. As COVID infections continue to be common, studying the long-term consequences of coronavirus disease (COVID) on physical function has become increasingly important. This narrative review will aim to summarize the current literature surrounding exercise intolerance following COVID infection in terms of mechanism, current management approaches, and comparison with similar conditions and will aim to define limitations in the current literature. Multiple organ systems have been implicated in the onset of long-lasting exercise intolerance post-COVID, including cardiac impairment, endothelial dysfunction, decreased VO2 max and oxygen extraction, deconditioning due to bed rest, and fatigue. Treatment modalities for severe COVID have also been shown to cause myopathy and/or worsen deconditioning. Besides COVID-specific pathophysiology, general febrile illness as commonly experienced during infection will cause hypermetabolic muscle catabolism, impaired cooling, and dehydration, which acutely cause exercise intolerance. The mechanisms of exercise intolerance seen with PASC also appear similar to post-infectious fatigue syndrome and infectious mononucleosis. However, the severity and duration of the exercise intolerance seen with PASC is greater than that of any of the isolated mechanisms described above and thus is likely a combination of the proposed mechanisms. Physicians should consider post-infectious fatigue syndrome (PIFS), especially if fatigue persists after six months following COVID recovery. It is important for physicians, patients, and social systems to anticipate exercise intolerance lasting for weeks to months in patients with long COVID. These findings underscore the importance of long-term management of patients with COVID and the need for ongoing research to identify effective treatments for exercise intolerance in this population. By recognizing and addressing exercise intolerance in patients with long COVID, clinicians can provide proper supportive interventions, such as exercise programs, physical therapy, and mental health counseling, to improve patient outcomes.

Correlation Between Intracranial Calcification and Extracranial Stenosis of the Internal Carotid Artery.

Intracranial artery calcification is a marker of vascular atherosclerosis and has a high prevalence worldwide. Both atherosclerosis of the internal carotid artery at the carotid sinus in the neck and intracranial calcification have been associated with ischemic stroke. The relationship between the two has not been well studied. The present study investigated how carotid sinus narrowing could relate to calcification located in the distal intracranial artery at the cavernous carotid. We examined a population not selected for cerebral disease. This retrospective study contained 179 subjects aged 18 years and older from the Hawaii Diagnostic Radiology database. Extracranial internal carotid artery stenosis was determined using the absolute diameter, North American Symptomatic Carotid Endarterectomy Trial, and common carotid artery methods. Calcification was scored using the modified Woodcock method. A positive correlation between intracranial calcification and extracranial carotid stenosis was found using all three methods. Individuals with intracranial calcification were more likely to be older, have a smaller internal carotid artery diameter, and have a greater percent stenosis at the internal carotid artery than those without intracranial artery calcification (p<0.001 for all). These results may help refocus interest in calcification in studies of cerebral vasculature and its correlation with extracranial carotid stenosis.

The Gomez-Lopez-Hernandez Syndrome: The Contribution of 2 Hispanic Giants of Pediatric Neurology.

The specialty of Pediatric Neurology emerged during the 20th century, a period in which many neurologists played significant roles in revolutionizing this field. Two acclaimed pediatric neurologists of Hispanic origin, Drs Manual Gomez and Arturo Lopez-Hernandez, made substantial contributions to the literature on pediatric neurology. One of their remarkable contributions was their discovery of a new, rare neurocutaneous syndrome with variable phenotype, the Gomez-Lopez-Hernandez syndrome (GLHS). Here, we describe the current understanding of GLHS and the historical background of how 2 celebrated Hispanic pediatric neurologists discovered this rare, sporadic syndrome during a time when there was a limited representation of minorities in the medical profession.

Demographic recruitment bias of adults in United States randomized clinical trials by disease categories between 2008 to 2019: a systematic review and meta-analysis.

To promote health equity within the United States (US), randomized clinical trials should strive for unbiased representation. Thus, there is impetus to identify demographic disparities overall and by disease category in US clinical trial recruitment, by trial phase, level of masking, and multi-center status, relative to national demographics. A systematic review and meta-analysis were conducted using MEDLINE, Embase, CENTRAL, and ClinicalTrials.gov, between 01/01/2008 to 12/30/2019. Clinical trials (N = 5,388) were identified based on the following inclusion criteria: study type, location, phase, and participant age. Each clinical trial was independently screened by two researchers. Data was pooled using a random-effects model. Median proportions for gender, race, and ethnicity of each trial were compared to the 2010 US Census proportions, matched by age. A second analysis was performed comparing gender, race, and ethnicity proportions by trial phase, multi-institutional status, quality, masking, and study start year. 2977 trials met inclusion criteria (participants, n = 607,181) for data extraction. 36% of trials reported ethnicity and 53% reported race. Three trials (0.10%) included transgender participants (n = 5). Compared with 2010 US Census data, females (48.3%, 95% CI 47.2-49.3, p < 0.0001), Hispanics (11.6%, 95% CI 10.8-12.4, p < 0.0001), American Indians and Alaskan Natives (AIAN, 0.19%, 95% CI 0.15-0.23, p < 0.0001), Asians (1.27%, 95% CI 1.13-1.42, p < 0.0001), Whites (77.6%, 95% CI 76.4-78.8, p < 0.0001), and multiracial participants (0.25%, 95% CI 0.21-0.31, p < 0.0001) were under-represented, while Native Hawaiians and Pacific Islanders (0.76%, 95% CI 0.71-0.82, p < 0.0001) and Blacks (17.0%, 95% CI 15.9-18.1, p < 0.0001) were over-represented. Inequitable representation was mirrored in analysis by phase, institutional status, quality assessment, and level of masking. Between 2008 to 2019 representation improved for only females and Hispanics. Analysis stratified by 44 disease categories (i.e., psychiatric, obstetric, neurological, etc.) exhibited significant yet varied disparities, with Asians, AIAN, and multiracial individuals the most under-represented. These results demonstrate disparities in US randomized clinical trial recruitment between 2008 to 2019, with the reporting of demographic data and representation of most minorities not having improved over time.

Identification of associations and distinguishing moyamoya disease from ischemic strokes of other etiologies: A retrospective case-control study.

Introduction: Better characterizing moyamoya disease (MMD) from ischemic strokes of other etiologies may facilitate earlier diagnosis by raising suspicion for a diagnostic work-up. Methods: To identify associated variables, MMD cases (n = 12) were compared against three sets of controls: age-, sex-, and race-matched controls of patients with general neurological disorders (n = 48), unmatched general controls (n = 48), and unmatched non-MMD ischemic stroke controls (n = 48). Results: MMD patients were 32 years (p < 0.0001) younger than ischemic stroke controls. Relative to non-MMD ischemic strokes, MMD patients had greater odds of presenting with visual field defects (OR: 9.13, p = 0.09) or dizziness (OR: 9.13, p = 0.09), as well as being female (OR: 8.04, p = 0.008), Asian (OR: 3.68, p = 0.087), employed (OR: 6.96, p = 0.02), having migraines (OR: 21.61, p = 0.005), epilepsy (OR: 6.69, p = 0.01), insomnia (OR: 8.90, p = 0.099), and a lower Charlson Comorbidity Index (CCI; p = 0.002). Patients with MMD, compared to non-MMD ischemic strokes, also had a 4.67 kg/ m 2 greater body mass index (BMI) and larger odds (OR relative to normal BMI: 21.00, p = 0.03) of being from obesity class III (>40 kg/ m 2 ), yet reduced odds of coronary artery disease (OR: 0.13, p = 0.02). Relative to general controls, MMD patients had greater odds of diabetes mellitus type 2 (OR: 10.07, p = 0.006) and hypertension (OR: 7.28, p = 0.004). Conclusion: MMD not only has a unique clinical presentation from other ischemic strokes, but also unique comorbidities, which may facilitate earlier work-up and treatment.

Identification of risk factors and distinguishing psychogenic nonepileptic seizures from epilepsy: A retrospective case-control study.

INTRODUCTION: Patients with psychogenic non-epileptic seizures (PNES) experience significant morbidity and early mortality, secondary to delayed diagnosis. Better characterizing risk factors and exploring how PNES differentially affects sex and racial strata may facilitate earlier diagnosis. METHODS: From a Hawai'i neuroscience institution, 101 PNES patients were investigated in relation to sociodemographic and medical comorbidities. Cases were compared to 202 sex-, age-, and race-matched controls-representing patients with neurological disorders (general controls)-, as well as 404 unmatched epilepsy controls. RESULTS: Relative to general controls, PNES patients had increased odds (p < 0.05) of being: female, younger age, Native Hawaiian or other Pacific Islander (NHPI), suburban origin, from the lowest income quartile, Medicaid beneficiaries, homeless, current/former smoker, illicit drug users (marijuana, opioids/narcotics, polysubstance abuse), have anxiety, depression, post-traumatic stress disorder, bipolar disorder, traumatic history, World Health Organization obesity class 3, traumatic brain injury, epilepsy, and somatoform disorder. In relation to epilepsy controls, PNES patients exhibited increased odds of being: employed, having attention-deficit/hyperactivity disorder, asthma, migraines, and chronic pain. Relative to females, male PNES patients exhibited increased odds of military insurance, diabetes mellitus type 2, and hypertension. Relative to Whites, the NHPI and Asian PNES patients presented increased odds of asthma, migraines, chronic pain, gastroesophageal reflux disease, and thyroid disease. Per multivariable logistic regression, anxiety was the only consistent predictor of PNES across all sex and race strata. CONCLUSION: Predictors of PNES's vary amongst the strata of race and sex. Lower socioeconomic status, along with several psychiatric and medical comorbidities, could increase a clinician's suspicion for earlier medical workup and diagnosis of PNES.

Native Hawaiian and Other Pacific Islanders' Leading Risk Factors for Ischemic Stroke: A Comparative Ethnographic Study.

INTRODUCTION: Hawaii is a multicultural state with many different ethnicities, including Native Hawaiians and other Pacific Islanders (NHOPI). This demographic has not been thoroughly studied, despite its significantly higher prevalence of stroke. This study aimed to characterize risk factors for ischemic stroke in NHOPI compared to other ethnicities. METHODS: An Institutional Review Board (IRB) sanctioned retrospective chart review was conducted at a multi-site community neurology clinic from June 2017 through June 2019. Prospective patients were identified from the database using the International Classification of Diseases 10th Edition (ICD-10) codes for ischemic stroke. 326 patients (99 NHOPI, 116 Asian, 111 Caucasian) with a history of ischemic stroke met the inclusion criteria. Risk factors were determined based on the American Stroke Association guidelines; ethno-racial grouping was based on self-identification; and average household income levels were estimated based on patient zip codes US Census Bureau data. Continuous variable risk factors were analyzed using an analysis of variance (ANOVA) and post-hoc pairwise comparisons using Tukey-Kramer; a multivariate analysis was conducted. RESULTS: Compared to Asians and Caucasians, NHOPI patients were on average 11 years younger at the onset of stroke and more likely to be women. The NHOPI group also had the highest rates of diabetes and obesity. NHOPI average income was significantly lower compared to the Caucasian group. Hypertension and hyperlipidemia were found to be higher in the Asian population. Alcohol consumption was reported more frequently among Caucasian patients. CONCLUSIONS: These results better-characterized risk factors for ischemic stroke among NHOPI in Hawaii. The younger age of stroke onset in NHOPI patients is likely due to the higher burden of cardiovascular risk factors like obesity, smoking, and diabetes. Identifying such disparities in associated risk for NHOPI and other ethnicities can allow targeted stroke prevention and outpatient care in a multicultural setting.

Early Impact of the COVID-19 Pandemic on Outpatient Neurologic Care in Hawai'i.

In March 2020, Hawai'i instituted public health measures to prevent the spread of Coronavirus disease 2019 (COVID-19), including stay-at-home orders, closure of non-essential businesses and parks, use of facial coverings, social distancing, and a mandatory 14-day quarantine for travelers. In response to these measures, Hawai'i Pacific Neuroscience (HPN) modified practice processes to ensure continuity of neurological treatment. A survey of patients was performed to assess the impact of the COVID-19 pandemic and pandemic-related practice processes for quality improvement. Overall, 367 patients seen at HPN between April 22, 2020, and May 18, 2020, were surveyed via telephone. Almost half (49.6%) participated in a telemedicine appointment, with the majority finding it easy to use (87.4%) and as valuable as face-to-face appointments (68.7%). Many (44.5%) patients said they would have missed a health care appointment without the availability of telemedicine, and 47.3% indicated they might prefer to use telemedicine over in-person appointments in the future. Many reported new or worsening mental health problems, including depression (27.6%), anxiety (38.3%), or sleep disturbances (37.4%). A significant number reported worsening of their condition, with 33.1% of patients who experience migraines reporting increased symptom severity or frequency, 45.8% patients with Alzheimer's disease reporting worsened symptoms, 38.5% of patients with Parkinson's disease who had a recent fall, and 50.0% of patients with multiple sclerosis experiencing new or worsened symptoms. Insights from this survey applied to the practice's pandemic-related processes include emphasizing lifestyle modification, screening for changes in mental health, optimizing treatment plans, and continuing the option of telemedicine.

COVID-19 Is Changing Our Understanding of the Neuroscience of Viral Infections: What We Can Do to Prepare for the Future?

In the approximately two years since the emergence of COVID-19 (Coronavirus Disease 2019) myriad neurological symptoms have been reported that are seemingly unrelated to each other [...].

Variables Associated with Coronavirus Disease 2019 Vaccine Hesitancy Amongst Patients with Neurological Disorders.

INTRODUCTION: Given that the success of vaccines against coronavirus disease 2019 (COVID-19) relies on herd immunity, identifying patients at risk for vaccine hesitancy is imperative-particularly for those at high risk for severe COVID-19 (i.e., minorities and patients with neurological disorders). METHODS: Among patients from a large neuroscience institute in Hawaii, vaccine hesitancy was investigated in relation to over 30 sociodemographic variables and medical comorbidities, via a telephone quality improvement survey conducted between 23 January 2021 and 13 February 2021. RESULTS: Vaccine willingness (n = 363) was 81.3%. Univariate analysis identified that the odds of vaccine acceptance reduced for patients who do not regard COVID-19 as a severe illness, are of younger age, have a lower Charlson Comorbidity Index, use illicit drugs, or carry Medicaid insurance. Multivariable logistic regression identified the best predictors of vaccine hesitancy to be: social media use to obtain COVID-19 information, concerns regarding vaccine safety, self-perception of a preexisting medical condition contraindicated with vaccination, not having received the annual influenza vaccine, having some high school education only, being a current smoker, and not having a prior cerebrovascular accident. Unique amongst males, a conservative political view strongly predicted vaccine hesitancy. Specifically for Asians, a higher body mass index, while for Native Hawaiians and other Pacific Islanders (NHPI), a positive depression screen, both reduced the odds of vaccine acceptance. CONCLUSION: Upon identifying the variables associated with vaccine hesitancy amongst patients with neurological disorders, our clinic is now able to efficiently provide ancillary COVID-19 education to sub-populations at risk for vaccine hesitancy. While our results may be limited to the sub-population of patients with neurological disorders, the findings nonetheless provide valuable insight to understanding vaccine hesitancy.

Disparities in Alzheimer Disease and Mild Cognitive Impairment Among Native Hawaiians and Pacific Islanders.

BACKGROUND: Previous studies of racial differences in Alzheimer disease (AD) presentation have not included Native Hawaiians and Pacific Islanders (NHPI). OBJECTIVE: To explore the presentation of AD and mild cognitive impairment (MCI) in NHPI. METHOD: We conducted a retrospective review of patient records from Hawaii with a diagnosis of unspecified AD or MCI from September 2000 to September 2019. Variables of interest included age at diagnosis, gender, race, marital status, insurance, comorbidities, and scores on the Mini-Mental State Examination (MMSE) or the Montreal Cognitive Assessment (MoCA). RESULTS: We reviewed the medical records of 598 patients, including 224 Asians, 202 Whites, 87 NHPI, and 85 Other. AD was more dominant than MCI across all of the groups, with the highest percentage in NHPI. Among the mean ages of diagnosis, NHPI were the youngest. Across all groups, a higher proportion of women than men had AD, with the highest female prevalence among NHPI. Hypertension, hyperlipidemia, and type II diabetes were highest among NHPI compared with the other groups. Of individuals with MMSE/MoCA scores, there were significant variations in scores by racial group. The mean MMSE/MoCA score was highest among Whites and lowest among NHPI. CONCLUSION: Compared with other racial groups, NHPI have a higher proportion of AD than MCI at diagnosis, are diagnosed at a younger age, have a higher female prevalence, have more comorbidities that may contribute to AD/MCI onset, and present with lower MMSE scores.

Effectiveness of dual migraine therapy with CGRP inhibitors and onabotulinumtoxinA injections: case series.

AIMS: Clinical trials for calcitonin gene-related peptide (CGRP) inhibitors excluded the concomitant use of onabotulinumtoxinA; thus, there is a lack of efficacy and safety data of the combined therapies. Our study aims to examine the effectiveness of CGRP inhibitors with onabotulinumtoxinA by evaluating migraine reductions in headache days and severity. METHODS: Seventeen patients with chronic migraines were identified who had a partial or poor response to onabotulinumtoxinA, and were placed on dual therapy with a CGRP inhibitor. Patients' initial headache days and severity ratings were compared to final values taken 1-6 months after adding the CGRP inhibitor to their treatment regime. Comparisons between headache days and severity ratings prior to and during dual treatment were performed utilizing the Kruskal-Wallis test. The significance was set at p < 0.05. RESULTS: Of 17 patients (16F/1 M), n = 9 were taking fremanezumab, n = 4 were taking erenumab, and n = 4 were taking galcanezumab. Patients' average headache days per month was reduced from 27.6 ± 4.8 initially to 18.6 ± 9.4 post-treatment (p = 0.00651), and their average pain level was reduced from 8.4 ± 1.4 out of 10 to 5.4 ± 2.5 (p = 0.00074). No serious adverse side effects were reported from patients on dual therapy. CONCLUSION: Patients with suboptimal response to onabotulinumtoxinA may benefit from CGRP inhibitors' addition to their migraine regimens. Placebo-controlled randomized studies are advised to corroborate this finding.

Characterizing idiopathic intracranial hypertension socioeconomic disparities and clinical risk factors: A retrospective case-control study.

INTRODUCTION: Against the backdrop of the diverse minority-majority state of Hawaii, this study seeks to better characterize associations between idiopathic intracranial hypertension (IIH) with sociodemographic variables and medical comorbidities. METHODS: A retrospective case-control study was conducted by utilizing 54 IIH patients and 216 age-, sex-, and race-matched controls, 216 unmatched controls, and 63 age-, sex-, and race-matched migraine patients. RESULTS: Relative to controls, IIH were 25 years younger (p < 0.0001) and 10.18 kg/m2 heavier (p < 0.0001), as well as exhibited greater odds of the following variables (p < 0.05): female (odds ratio [OR]: 8.87), the lowest income quartile (OR: 2.33), Native Hawaiian or other Pacific Islander (NHPI; OR: 2.23), Native American or Alaskan Native (OR: 16.50), obesity class 2 (35.0-39.9 kg/m2; OR: 4.10), obesity class 3 (>40 kg/m2; OR: 6.10), recent weight gain (OR: 11.66), current smoker (OR: 2.48), hypertensive (OR: 3.08), and peripheral vascular disease (OR: 16.42). Odds of IIH were reduced (p < 0.05) for patients who were Asian (OR: 0.27) or students (OR: 0.30;). Unique from Whites, NHPI IIH patients exhibited greater odds (p < 0.05) for being from lower socioeconomic status and currently smoking, as well as potential association with seizures (p = 0.08). Compared to migraines, IIH headaches were at increased odds of occurring (p < 0.05) occipitally, for greater than 15 days per month, aggravated by postural changes, and comorbid with dizziness and tinnitus. CONCLUSIONS: These results not only better characterize IIH, but also highlight socioeconomic and racial disparities in diagnosis.

A Case Report of Antibiotic-Induced Aseptic Meningitis in Psoriasis.

Although frequently prescribed, certain antibiotics such as trimethoprim-sulfamethoxazole carry the risk of a rare yet life-threatening adverse effect, termed drug-induced aseptic meningitis. Morbidity can be avoided if the medication is identified and discontinued. Patients in reported cases tend to be female and have an autoimmune disease or prior adverse reaction to the offending agent. As a rare and poorly characterized condition, the subset of patients using antibiotics at risk for aseptic meningitis remains unclear; hence, cataloging these adverse events remains critical for better elucidating the disease. Here, we report a 62-year-old man with psoriasis and no prior history of sulfa allergy, who presented with a sudden onset of fever, chills, vomiting, and muscle aches 5 hours after taking single doses of trimethoprim-sulfamethoxazole and ciprofloxacin. Common infectious causes were ruled out, and his medications were discontinued. Despite initial symptom resolution with discontinuation, the patient neurologically deteriorated over the next two days before eventually recovering with supportive care. This case highlights the variable presentation of drug-induced aseptic meningitis. In contrast to previous reports of drug-induced aseptic meningitis, our patient was male, older than the median age of 40 years, and did not have a prior adverse reaction to the antibiotic. Furthermore, to the best of our knowledge, we report a possible case of antibiotic-induced aseptic meningitis in a patient with psoriasis. Lastly, the case emphasizes not only the value of a thorough medication history but also the importance of recognizing that patients may deteriorate in the first 48 hours before resolution.

Early impact of the COVID-19 pandemic on outpatient migraine care in Hawaii: Results of a quality improvement survey.

OBJECTIVE: A survey was implemented for early assessment of pandemic-related practice processes and quality improvement (QI). BACKGROUND: In response to the public health measures in Hawaii to curtail the coronavirus 2019 pandemic, Hawaii Pacific Neuroscience (HPN) adapted their patient care to ensure continuity of neurological treatment. METHODS: The telephone survey was conducted on patients seen at HPN during the period of April 22, 2020-May 18, 2020 to address four areas related to patients' outpatient experience: delivery of care, general well-being, experience with telemedicine, and disease-specific questions. RESULTS: A total of 928 patients were contacted of which 429 (46.2%) patients responded and 367 (85.5%) agreed to participate. A total of 133 patients with migraine and 234 patients with other neurological conditions provided responses. Our migraine patients' survey responses suggest that their well-being was disproportionately negatively affected by the pandemic. Survey respondents with migraine were significantly more likely than their non-migraine peers to report worsening anxiety and sleep problems [62/132 (47.0%) vs. 78/234 (33.3%), χ2  = 6.64, p = 0.010, and 64/132 (48.5%) vs. 73/234 (31.2%), χ2  = 10.77, p = 0.001]; migraine patients also reported worsening of depression as a result of the pandemic more than patients with other diagnoses, though this was not statistically significant [44/132 (33.3%) vs. 57/234 (24.4%), χ2  = 3.40, p = 0.065]. In regard to access to healthcare, significantly more migraine patients reported running out of medications than those with other diagnoses [20/133 (15.0%) vs. 18/234 (7.7%), χ2  = 4.93, p = 0.026]. More avoided seeking medical help for new health problems because of the pandemic [30/133 (22.6%) vs. 30/234 (12.8%), χ2  = 5.88, p = 0.015]. Migraine patients were also significantly impacted economically by the pandemic; 43/132 (32.4%) of migraine patients reported losing their jobs as the result of the pandemic versus 34/234 (14.5%) of their peers (χ2  = 11.20, p < 0.001). An increase in headache severity or frequency was reported in 39/118 (33.1%) of respondents and 19/118 (16.1%) reported to using more abortive therapy than usual. Telemedicine was well received by almost all patients who took advantage of the option. Most of those patients found telemedicine to be easy to use and as valuable as an in-person visit. Migraine patients indicated with more frequency that without the telemedicine option, they would have missed their medical appointments [37/68 (54.4%) vs. 56/144 (38.6%), χ2  = 4.31, p = 0.038]; a majority would prefer or consider telemedicine for future appointments over in-person visits. CONCLUSIONS: Insights gained from this QI survey to the practice's new pandemic-related processes include stressing lifestyle modification, optimizing treatment plans, and continuing the option of telemedicine.

Role of psychiatric, cardiovascular, socioeconomic, and demographic risk factors on idiopathic normal pressure hydrocephalus: A retrospective case-control study.

OBJECTIVES: Currently, predicting and preventing idiopathic normal pressure hydrocephalus (iNPH) remains challenging, especially for patients without a history of cerebrovascular disease. By exploring the role of cardiovascular and psychiatric history, demographics, and socioeconomic status in iNPH, will provide better direction for elucidating the etiology or addressing healthcare inequalities. PATIENTS AND METHODS: To investigate iNPH with respect to the selected risk factors, we conducted a retrospective case-control study from a neuroscience institute in Hawaii with a patient pool of 25,843. After excluding patients with a history of cerebrovascular disease, we identified 29 cases which meet the American-European guidelines for iNPH diagnosis. Meanwhile, 116 controls matched to age, sex, and race were also randomly selected. RESULTS: Median age at diagnosis was 83 (IQR: 74-88), with cases estimated 22 years older than controls (95 % CI: 14.00-29.00; p = 0.0000001). Patients with iNPH were more likely to be White (OR 4.01, 95 % CI: 1.59-10.11; p = 0.0042) and less likely Native Hawaiian and other Pacific Islander (OR 0.010, 95 % CI: 0.00-0.78; p = 0.014). Median household income was $2874 (95 % CI: 0.000089-6905; p = 0.088) greater amongst iNPH cases. Effect size amongst cardiovascular risk factors was not found statistically significant (i.e., body mass index, hyperlipidemia, type 2 diabetes mellitus, hypertension, coronary artery disease or prior myocardial infarction history, peripheral vascular disease, smoking status, congestive heart failure, atrial fibrillation/flutter, and history of prosthetic valve replacement). However, iNPH patients were more likely to have a history of alcohol use disorder (OR 8.29, 95 % CI: 0.99-453.87; p = 0.050) and history of a psychiatric disorder (OR 2.48; 95 % CI: 1.08-5.68; p = 0.029). Odds ratio for autoimmune disorder, thyroid disorder, glaucoma, and seizures did not reach statistical significance. CONCLUSION: Patient race (i.e., White; Native Hawaiian or other Pacific Islander) was found associated with iNPH development. Meanwhile, after excluding those with cerebrovascular disease, cardiovascular risk factors were not found associated with iNPH. Lastly, iNPH cases were more inclined to have a history of alcohol use disorder and prior psychiatric disorder. Overall, this data reveals that a racial disparity exists amongst iNPH, as well as highlights the role of various cardiovascular and psychiatric risk factors, which can potentially provide direction in etiology elucidation.

Acute stroke, catheter related venous thrombosis, and paradoxical cerebral embolism: report of two cases.

BACKGROUND: Patent foramen ovale (PFO) has been associated with cryptogenic stroke, particularly in young adults. However, the source of particles leading to cerebral embolism remains frequently unknown despite comprehensive evaluation. OBJECTIVE: To report and comment on therapeutic options for 2 patients with acute ischemic strokes, PFO, and venous access related thrombosis, sources of paradoxical embolism, from Boston Medical Center stroke database. CASE DESCRIPTIONS: Case 1. A 71-year-old man presented with brain magnetic resonance imaging (MRI) confirmed acute cerebellar infarction. Echocardiography showed a PFO and thrombotic material at the tip of a peripherally inserted central catheter (PICC) line in the superior vena cava (SVC) prolapsing into the right atrium (RA). Case 2. A 64-year-old woman with end-stage renal disease and PFO presented with brain MRI confirmed acute parietal lobe infarction. Three days prior to her stroke, she had thrombectomy and venoplasty of an arterio-venous (AV) dialysis graft followed by a post-thrombectomy fistulogram that showed persistent thrombotic material at the venous site. CONCLUSIONS: PFO associated with large venous access site thrombosis was the most likely mechanism of stroke in both cases. Local thrombosis at sites of large venous access may be an overlooked source of paradoxical embolism in patients with PFO as well as a preventable cause of stroke in critically ill patients.
