RESUMO

OBJECTIVE: Cognitive impairment is a potential drawback of antiseizure medications. This study aimed to evaluate the impact of different levetiracetam drug regimens on cognitive function. METHODS: A retrospective analysis identified 221 patients diagnosed with seizures who underwent cognitive screening. Patients were categorized into four groups: no medications, non-levetiracetam medications, high and low dose levetiracetam. Composite scores determined low and high levetiracetam groups whereby one point was added for each increment in dosage, duration since uptake, and concurrent anti-seizure medication. Variables known to affect cognition were recorded and classified as demographic, seizure-related, diagnosis-related, and psychopathology. Logistic regression was used to identify variables associated with cognitive scores below cut-off. RESULTS: Multivariable analysis found being male, non-active in the community, less than 12 years of education, left temporal lobe epilepsy, high seizure frequency, and depression were associated with poor cognitive performance. In a final regression analysis, the high levetiracetam group exhibited a 4.5-fold higher likelihood of scoring below cut-off than the medication-free group (OR 4.5, CI 1.5-13.6, p<.08). Depression (OR 2.1, CI 1.1-3.9, p<.03), being male (OR 2.2, CI 1.1-4.3, p<.02), and not being active in the community (OR 3.8, 1.6-8.7, p <.003) remained significant contributors to the model. Language (p<.05), attention (p<.05), and delayed recall (p<.001) were the most affected cognitive domains. SIGNIFICANCE: When taken in small doses, for brief periods as monotherapy, levetiracetam minimally influences cognition. At higher doses, as part of long-term seizure management, in conjunction with multiple ASMs, LEV is associated with cognitive impairment.

RESUMO

Background: Literature on telehealth interventions for older adults has been primarily on asynchronous interventions. During the COVID-19 pandemic, older adult exercise programs transitioned to an online format. This systematic review and case study examines the effectiveness of older adult live video exercise group interventions on physical health with insights from a Los Angeles VA program, Gerofit. Methods: PubMed was searched for live video older adult exercise groups from database inception to November 2021. All eligible studies included assessments of physical health and were limited to participants with an average age of 65 years or greater. Ten Veterans, who had participated in both in-person and virtual Gerofit sessions, were surveyed in the case study. Results: Nine studies met the inclusion criteria. Four studies included an equivalent in-person group as a comparator to the live video group and reported no significant between-group differences in outcomes, including energy expenditure and 6-minute walking distance test (6MWD). The other five studies reported statistically significant in-group improvement in outcomes including isokinetic knee strength. Case study participants reported similar attendance rates and perceived benefits, such as improved balance, when comparing virtual and in-person sessions. Discussion: Live video exercise groups in older adults demonstrated an improvement in physical function that was not statistically different from the comparison in-person sessions with the added benefit of averaging a higher attendance rate, providing initial support for the use of live video in older adult exercise programs. Insights from the case study supplement this by demonstrating older adults' positive attitude on these groups.

RESUMO

BACKGROUND: To estimate the lifetime prevalence and potential determinants of psychotic experience(s) (PEs) in the general population of Qatar - a small non-war afflicted, conservative, high-income, middle-eastern country with recent rapid urbanization including an influx of migrants. METHODS: A probability-based sample (n = 1353) of non-migrants and migrants were interviewed face-to-face and administered a 7-item psychosis screener adapted from the Composite International Diagnostic Interview, the Kessler 6-item psychological distress scale, and the 5 items assessing odd (paranormal) beliefs and magical thinking (OBMT) from the Schizotypal Personality Questionnaire. Using bivariate and logistic regression analyses, lifetime prevalence rates of PEs were estimated then compared before and after adjustment for socio-demographics, Arab ethnicity, psychological distress, and OBMT. RESULTS: Prevalence of PEs was 27.9%. Visual hallucinations were most common (12.8%), followed by persecutory delusions (6.7%) and auditory hallucinations (6.9%). Ideas of reference (3.6%) were least prevalent. PEs were significantly higher in Arabs (34.7%) compared with non-Arabs (16.4%, p < 0.001) with the exception of ideas of reference and paranoid delusions. Female gender was associated with a higher prevalence of PEs in the Arab group only (p < 0.001). Prevalence of PEs was significantly higher among Arabs (48.8% v. 15.8%, p < 0.001) and non-Arabs (35.2% v. 7.3%, p < 0.001) with OBMT. Arab ethnicity (OR = 2.10, p = 0.015), psychological distress (OR = 2.29 p = 0.003), and OBMT (OR = 6.25, p < 0.001) were independently associated with PEs after adjustment for all variables. CONCLUSIONS: Ethnicity, but not migration was independently associated with PEs. Evidence linking Arab ethnicity, female gender, and psychological distress to PEs through associations with OBMT was identified for future prospective investigations.

RESUMO

OBJECTIVE: Approximately 30% of individuals who initially present with stroke are found to be stroke mimics (SM), with functional/psychological SM (FSM) accounting for up to 6.4% of all stroke presentations. Middle Eastern countries may have higher rates of somatization of emotional distress. The aim of this study was to evaluate the incidence and characteristics of FSM at a large general hospital in the Middle East. METHODS: All patients presenting with an initial diagnosis of stroke from June 2015 to September 2016 were eligible for this study. Clinical and sociodemographic data were obtained from the hospital's stroke database. All SM and strokes were diagnosed by Joint Commission International-certified stroke program neurologists. SM was defined as any discharge diagnosis (other than acute stroke) for symptoms that prompted initial admission for suspected stroke. FSM were compared with medical stroke mimics (MSM) and strokes (ischemic, hemorrhagic, and transient ischemic attacks). RESULTS: A total of 1961 patients were identified; 161 FSM (8.2%), 390 MSM (19.9%), and 1410 strokes (71.9%) (985 ischemic strokes, 196 transient ischemic attacks, 229 intracerebral hemorrhages). Admission with FSM was related to patients' nationality, with the highest frequency in Arabic (15.6%) and African (16.8%) patients. FSM patients were younger, more often female, and had fewer cardiovascular risk factors except for smoking compared with the strokes. FSM patients presented with more left-sided weakness and had more magnetic resonance imagings than the stroke and MSM groups. A total of 9.9% of FSM patients received thrombolysis versus only 0.5% of the MSM and 16.4% of ischemic strokes. CONCLUSIONS: FSM frequencies varied by nationality, with Arab and African nationals being twice as prevalent. Stress, vulnerable status as expats, sociopolitical instability, and exposure to trauma are proposed as potential factors contributing to FSM.

RESUMO

OBJECTIVE: The Middle Eastern country of Qatar opened its first epilepsy monitoring unit (EMU) in late 2015. This study compared demographic and clinical characteristics of patients with confirmed epilepsy to those of patients with confirmed psychogenic nonepileptic seizures (PNES). METHODS: Data were collected via retrospective chart review on 113 patients admitted for evaluation to the Qatar national health system EMU between November 2015 and May 2017. RESULTS: Seventy-one patients had a confirmed diagnosis (20 had PNES, 46 had epilepsy, 5 had both PNES and epilepsy). Evaluation in 33 patients was inconclusive, and 9 had other medical conditions. Patients with PNES were significantly more likely to be primary Arabic speakers (p = 0.003), and this difference was not explained by education or employment status. The most common referral request in patients with PNES was for recurrent/refractory seizures (p = 0.011), and there was a trend for patients with PNES to have more frequent seizures compared with patients with epilepsy (daily to several per week versus several times a month or less, p = 0.051). Depression was identified in 47% of patients with epilepsy and 65% of patients with PNES, and patients with PNES had higher mean depression scores on the PHQ-9 than patients with epilepsy (p = 0.014). Patients with PNES experienced significantly more fatigue (p = 0.021). Seventy percent of patients with PNES and 50% of patients with epilepsy reported sleep problems. CONCLUSIONS: The characteristics of patients with epilepsy and PNES at the EMU in Qatar were generally similar to those found worldwide. Patients with PNES more often suffered from frequent depression, sleep problems, and fatigue than those with epilepsy, but these were significant concerns for both groups.

RESUMO

Stroke is a major cause of mortality and disability globally that has multiple risk factors. A risk factor that has recently gained more attention is post-traumatic stress disorder (PTSD). Literature searches were carried out for updated PTSD information and for the relationship between PTSD and stroke. The review was divided into two sections, one exploring PTSD as an independent risk factor for stroke, with a second concentrating on PTSD's influence on stroke risk factors. The study presents accumulating evidence that shows traumatic stress predicts stroke and is also linked to many major stroke risk factors. The review contributes knowledge to stroke aetiology and acts as a reference for understanding the relationship between PTSD and stroke. The information presented indicates that screening and identification of traumatic experience would be beneficial for directing stroke patients to appropriate psychological and lifestyle interventions. In doing so, the burden of stroke may be reduced worldwide.

RESUMO

OBJECTIVE: Post-traumatic stress disorder (PTSD) is common in Veterans. Symptoms can perpetuate into late life, negatively impacting physical and mental health. Exercise and social support are beneficial in treating anxiety disorders such as PTSD in the general population, although less is known about the impact on Veterans who have lived with PTSD for decades. This study assessed associations between social connectedness, physical function and self-reported change in PTSD symptoms among older Veterans specifically participating in Gerofit. DESIGN: Prospective clinical intervention. SETTING: Twelve sites of Veterans Affairs (VA) Gerofit exercise program across the United States. PARTICIPANTS: Three hundred and twenty one older Veteran Gerofit participants (mean age = 74) completed physical assessments and questionnaires regarding physical and emotional symptoms and their experience. MEASUREMENTS: Measures of physical function, including 30-second chair stands, 10-m and 6-min walk were assessed at baseline and 3 months; change in PTSD symptoms based on the Diagnostic Statistical Manual-5 (DSM-5) assessed by a self-report questionnaire; and social connection measured by the Relatedness Subscale of the Psychological Need Satisfaction in Exercise scale (PNSE) were evaluated after 3 months of participation in Gerofit. RESULTS: Ninety five (29.6%) Veterans reported PTSD. Significant improvement was noted in self-rated PTSD symptoms at 3 months (P < .05). Moderate correlation (r = .44) was found between social connectedness with other participants in Gerofit and PTSD symptom improvement for those Veterans who endorsed improvement (n = 59). All participants improved on measures of physical function. In Veterans who endorsed PTSD there were no significant associations between physical function improvement and PTSD symptoms. CONCLUSION: Veterans with PTSD that participated in Gerofit group exercise reported symptom improvement, and social connectedness was significantly associated with this improvement. In addition to physical health benefits, the social context of Gerofit may offer a potential resource for improving PTSD symptoms in older Veterans that warrants further study.

RESUMO

Physical activity improves overall health and reduces the risk of many negative health outcomes and may be effective in improving cognition, independent functioning, and psychological health in older adults. Given the evidence linking physical activity with improvements in various aspects of health and functioning, interventions exploring pathways for decreasing risk of dementia in those with mild cognitive impairment (MCI) and improving outcomes for those with dementia are of critical importance. The present review highlights the work examining physical activity interventions in order to achieve a comprehensive understanding of the potential benefits of physical activity for individuals experiencing cognitive decline. The primary focus is on aerobic exercise as this is the main intervention in the literature. Our review supports the thesis that physical activity can promote healthy aging in terms of cognition, independent functioning, and psychological health for individuals experiencing cognitive decline. Specifically, physical activity improves cognition, especially executive functioning and memory in MCI, independent functioning in MCI and dementia, and psychological health in dementia. Given that benefits of physical activity have been observed across these domains, such interventions provide an avenue for preventing decline and/or mitigating impairment across several domains of functioning in older adults with MCI or dementia and may be recommended (and adjusted) for patients across a range of settings, including medical and mental health settings. Further implications for clinical intervention and future directions for research are discussed.

RESUMO

OBJECTIVE: Depression occurs in approximately 30 percent of stroke patients, leading to increased disability, lower quality of life and increased mortality. Given new recommendations to assess depression in acute stroke patients this study evaluated rates of acute post stroke depression at a Primary Stroke Center in Doha, Qatar. METHODS: Acute stroke patients (n = 233) were given the PHQ-9 and the Mini-Cog test by stroke unit nurses within the first few days post stroke. This was part of a clinical improvement project conducted from March 2016 thru March 2017. RESULTS: Approximately 20% of acute post stroke patients (46/233) scored in the moderately depressed range on the Patient Health Questionnaire (PHQ-9 ≥10 with item 1 and/or 2 endorsed). Nationality and dysarthria were significantly associated with depression. Females were twice as likely to be depressed. A significantly greater number of Middle Eastern and African patients were depressed (30.18%) than Southeast Asian and Western Pacific patients (16.76%). A PHQ-2 cut off of 2 was optimal with sensitivity of 91.3 and specificity of 71.6. CONCLUSIONS: Almost 20% of acute stroke patients were moderately depressed on the PHQ-9, with Middle Eastern/African patients almost twice as likely to be depressed. This may reflect higher baseline pre-stroke depression levels in those of Middle Eastern/African background, perhaps due to greater levels or stress or trauma exposure in these groups. Dysarthria was found to be significantly associated with depression. Initial screening with the PHQ-2 using a cut-off of 2 (versus the cut-off of 3 used in primary care settings) may be beneficial. Based on these results acute post stroke depression screening is recommended in the Middle East, coupled with culturally sensitive psychiatric care.

RESUMO

Early social dysfunction is a hallmark symptom of behavioral variant frontotemporal dementia (bvFTD); however, validated measures for assessing social deficits in dementia are needed. The purpose of the current study was to examine the utility of a novel informant-based measure of social impairment, the Socioemotional Dysfunction Scale (SDS) in early-onset dementia. Sixteen bvFTD and 18 early-onset Alzheimer's disease (EOAD) participants received standard clinical neuropsychological measures and neuroimaging. Caregiver informants were administered the SDS. Individuals with bvFTD exhibited greater social dysfunction on the SDS compared with the EOAD group; t(32) = 6.32, p < .001. The scale demonstrated preliminary evidence for discriminating these frequently misdiagnosed groups (area under the curve = 0.920, p = <.001) and internal consistency α = 0.977. The SDS demonstrated initial evidence as an effective measure for detecting abnormal social behavior and discriminating bvFTD from EOAD. Future validation is recommended in larger and more diverse patient groups.
