Brain health and value diversity: A new implementation field for values-based practice?

Brain health has recently emerged as an overarching concept encompassing cognitive, sensory, social-emotional, behavioural and motor aspects of brain functioning, enabling individuals to achieve their potential for both health and wellbeing over their life course, independent of the presence or absence of disease.1 It is contingent on a continuous, complex interplay between interconnected determinants related to physical health, healthy environments, safety and security, learning and social connection, and access to quality services. Even though responsibility for optimizing brain health can be taken at an individual level, brain health is in fact heavily influenced by determinants far beyond the control of individuals and their families. For instance, protection from abuse and maltreatment or equitable access to health services depend on interacting social, financial, and political factors that can often only be minimally influenced by individual or small group initiatives.2,3 In addition, the voice of many people, including the very young, the very old, the sick, the disadvantaged, and those who live in poverty, may not be sufficiently influential, even though the decision-making process crucially affects the brain health and quality of life for these individuals. The breadth of determinants of brain health makes brain health a terrain that is justifiably shaped by a plethora of stakeholders with highly diverse values and hence potentially conflicting interests and albeit different degrees of power. Consequently, decision-making in such contexts embodies a thorny process that may render the negligence of the values, viewpoints, and perspectives of those directly involved in a given decision, particularly when the individual capacity to advocate for oneself and the willingness of society and governments to act on behalf of their citizens, are low. Values-based practice (VBP) is a toolkit for balancing interests, wishes, and values in contexts characterized by diverse values, which may be valuable in decision-making related to brain health.4 The implementation of this toolkit in different fields of healthcare (e.g., occupational therapy, orthopedics, primary care, psychiatry, psychology, radiotherapy) has been proposed, and training materials for healthcare professionals have been developed.5 VBP aims to include the differences in values, viewpoints, and perspectives of those directly concerned with a given decision so that communication and shared decision-making are facilitated. Based on the legacy of the Popperian open society,5 VBP treats values in the same way that democracy treats ideas and human voices. Hence, this decision-making toolkit is neither restricted to ethical codes nor prioritizes one value over others. It also does not endorse certain values while excluding others, provided that the values in play are compatible with legal, regulatory, and bioethical frameworks. The emphasis of VBP is on good process rather than predetermined 'correct' outcomes.6,7 Respect for differences between stakeholders results in the creation of a culture of mutual responsibility and in building up a positive relationship between all those concerned, so that everyone feels a sense of ownership of the decision made.4,6 Of note, according to VBP, the perspective of the health service user or of the individuals or community seeking to protect their brain health is the ideal starting point for any decision. This approach minimizes the negligence of the views, needs, values, competencies, resources, and aspirations of those trying to optimize their brain health in contexts where powerful socioeconomic and further interests may be at stake. The 'good process' of VBP is safeguarded by ten principles.4 Four of them pertain to clinical skills and practice - awareness raising regarding the involvement of values in a given decision-making process; use of a clear reasoning strategy to explore value diversity; knowledge about the values and facts that may be relevant to different contexts; and good communication skills. Two further principles underscore the importance of person-centred and multidisciplinary health service delivery. Other principles focus on the fact that all decisions are based on both values and facts, where the former become noticeable particularly when they are diverse or conflicting, especially in environments where variable choices are at the disposal of service users. The last principle of VBP is based on partnership in decision-making, including both service users and providers. In conclusion, VBP may become a valuable tool for making balanced decisions in the broad terrain of brain health. Its protective focus on the perspectives of service users and its democratic character may pave the way towards achieving equity in and optimization of brain health.

Cognitive function in amyotrophic lateral sclerosis: a cross-sectional and prospective pragmatic clinical study with review of the literature.

BACKGROUND: Amyotrophic lateral sclerosis (ALS) can present with either bulbar or spinal symptoms, and in some cases, both types of symptoms may be present. In addition, cognitive impairment has been observed in ALS. The study aimed to evaluate the frontal and general cognitive performance in ALS not only cross-sectionally but also longitudinally. METHODS AND MATERIALS: The Frontal Assessment Battery (FAB) and the Montreal Cognitive Assessment (MoCA) were employed to assess cognitive function in 52 adults with ALS and 52 cognitively healthy individuals. The statistical analyses encompassed the Pearson Chi square test, the Skillings-Mack test, the Spearman's rank correlation coefficient, and the Proportional Odds Logistic Regression Model (POLR). RESULTS: Cross-sectionally, lower cognitive performance was associated with ALS diagnosis, older age, and motor functional decline. The cognitive impairment of individuals with bulbar and spinal-bulbar symptoms showed faster deterioration compared to those with spinal symptoms. The spinal subgroup consistently performed worst in delayed recall and attention, while the spinal-bulbar and bulbar subgroups exhibited inferior scores in delayed recall, attention, visuospatial skills, orientation, and verbal fluency. CONCLUSION: The incorporation of cognitive screening in the diagnostic workup of ALS may be beneficial, as early detection can enhance symptom management and improve the quality of life for both individuals with ALS and their care partners.

Depressive symptoms in the entire spectrum of cognitive ageing in Greece: evidence from the Hellenic Longitudinal Investigation of Aging and Diet (HELIAD).

OBJECTIVES: To study (i) the prevalence of mild and moderate-to-severe depressive symptoms in the entire spectrum of cognitive ageing in Greece and (ii) the relationship between these symptoms and demographic and clinical data. METHODS: The study was based on the randomly selected cohort of the Hellenic Longitudinal Investigation of Aging and Diet (HELIAD). Depressive symptoms were assessed with the 15-item version of the Geriatric Depression Scale. Participants also received a comprehensive neuropsychological assessment, while the clinical diagnoses of dementia and mild cognitive impairment were established according to international diagnostic criteria. Statistical analyses relied on comparison tests and a logistic (proportional odds) ordinal regression model. RESULTS: Depressive symptoms were detected in 19.5% of the 1936 study participants, while 11.3% of both people with MCI and dementia had moderate-to-severe depressive symptoms. The regression model revealed that older adults with more severe depressive symptoms were more likely female, cognitively impaired, less educated, were treated with psychotropic medication and lived in Attica versus Thessaly. CONCLUSIONS: Since depressive symptoms were detected in almost one in five older adults, healthcare professionals in Greece should safeguard the timely detection and effective treatment of such symptoms and the post-diagnostic care of older adults with depression.

Depressive symptoms are present in approximately 20% of older adults.More than 10% of older individuals with dementia or mild cognitive impairment report moderate-to-severe depressive symptoms.Female sex, lower education, lower cognitive performance, living in urban areas and treatment with psychotropic medication pertain to more severe depressive symptoms in ageing.Timely detection and effective treatment of depressive symptoms are crucial in the clinical practice of the care of older adults.Further research is needed in order to elucidate the complex relationship between depressive symptoms and cognitive impairment in ageing.

Association of Chronic Pain with Biomarkers of Neurodegeneration, Microglial Activation, and Inflammation in Cerebrospinal Fluid and Impaired Cognitive Function.

OBJECTIVE: Debate surrounds the role of chronic pain as a risk factor for cognitive decline and dementia. This study aimed at examining the association of chronic pain with biomarkers of neurodegeneration using data from the Alzheimer's Disease Neuroimaging Initiative. METHODS: Participants were classified using the ATN (amyloid, tau, neurodegeneration) classification. Chronic pain was defined as persistent or recurrent pain reported at baseline. For each ATN group, analysis of covariance models identified differences in cerebrospinal fluid (CSF) levels of amyloid ß1-42 , phosphorylated tau 181 (ptau181 ), total tau (t-tau), soluble triggering receptor expressed on myeloid cells 2 (sTREM2), and cognitive function between chronic pain states. Differences in CSF levels of inflammatory markers between chronic pain states were further analyzed. Linear mixed effect models examined longitudinal changes. RESULTS: The study included 995 individuals, with 605 (60.81%) reporting chronic pain at baseline. At baseline, individuals with suspected non-Alzheimer pathophysiology and chronic pain showed increased CSF levels of t-tau and sTREM2. Chronic pain was associated with increased tumor necrosis factor α levels, irrespective of the ATN group. Longitudinally, an increase in ptau181 CSF levels was observed in chronic pain patients with negative amyloid and neurodegeneration markers. Amyloid-positive and neurodegeneration-negative chronic pain patients showed higher memory function cross-sectionally. No significant longitudinal decline in cognitive function was observed for any ATN group. INTERPRETATION: Our study suggests that chronic pain induces neuronal damage and microglial activation in particular subgroups of patients along the AD spectrum. Further studies are needed to confirm these findings. ANN NEUROL 2023.

Low cognitive functioning and depressive symptoms in patients with rheumatoid arthritis and systemic sclerosis: a clinical study.

BACKGROUND: Recently, cognitive deficits occurring in rheumatic diseases have attracted scientific attention. Cognitive symptoms in patients with Rheumatoid Arthritis (RA) and Systemic Sclerosis (SSc) have not been thoroughly studied. This study aimed to assess cognitive function and its relationship with depressive symptoms in RA and SSc and compare it to mild neurocognitive disorder due to Alzheimer's disease (MiND) and to individuals without cognitive impairment. METHODS: Cognitive function and depressive symptoms were tapped with the Cognitive Telephone Screening Instrument plus (COGTEL+), the Serial Seven Test (SST), the Mini-Mental State Examination (MMSE) and the Geriatric Depression scale-15 (GDS), respectively. Statistical analyses included between groups-, correlation- and regression analyses. Demographic characteristics were considered in the regression models. RESULTS: The study included 30 individuals with RA, 24 with SSc, 26 adults without cognitive impairment and 33 individuals with MiND. Lower performance in verbal short-term memory, concentration/attention, verbal fluency and MMSE in patients with RA compared to individuals without cognitive impairment was detected. Of note, performance on verbal fluency, concentration/attention, inductive reasoning and MMSE was lower in RA compared to MiND. Individuals with SSc performed worse in verbal fluency and in MMSE in comparison to adults without cognitive deficits. Verbal fluency deficits in SSc exceeded that in MiND. Performance on MMSE, COGTEL+, prospective memory, working memory, verbal fluency and concentration/attention was related to GDS scores, which did not vary across the groups. CONCLUSIONS: Patients with RA and SSc encountered cognitive dysfunction, which partially pertains to depressive symptoms. Of note, the severity of cognitive dysfunction in many cases exceeded that of MiND.

Validation of the test for finding word retrieval deficits (WoFi) in detecting Alzheimer's disease in a naturalistic clinical setting.

BACKGROUND: Detecting impaired naming capacity contributes to the detection of mild (MildND) and major (MajorND) neurocognitive disorder due to Alzheimer's disease (AD). The Test for Finding Word retrieval deficits (WoFi) is a new, 50-item, auditory stimuli-based instrument. OBJECTIVE: The study aimed to adapt WoFi to the Greek language, to develop a short version of WoFi (WoFi-brief), to compare the item frequency and the utility of both instruments with the naming subtest of the widely used Addenbrooke's cognitive examination III (ACEIIINaming) in detecting MildND and MajorND due to AD. METHODS: This cross-sectional, validation study included 99 individuals without neurocognitive disorder, as well as 114 and 49 patients with MildND and MajorND due to AD, respectively. The analyses included categorical principal components analysis using Cramer's V, assessment of the frequency of test items based on corpora of television subtitles, comparison analyses, Kernel Fisher discriminant analysis models, proportional odds logistic regression (POLR) models and stratified repeated random subsampling used to recursive partitioning to training and validation set (70/30 ratio). RESULTS: WoFi and WoFi-brief, which consists of 16 items, have comparable item frequency and utility and outperform ACEIIINaming. According to the results of the discriminant analysis, the misclassification error was 30.9%, 33.6% and 42.4% for WoFi, WoFi-brief and ACEIIINaming, respectively. In the validation regression model including WoFi the mean misclassification error was 33%, while in those including WoFi-brief and ACEIIINaming it was 31% and 34%, respectively. CONCLUSIONS: WoFi and WoFi-brief are more effective in detecting MildND and MajorND due to AD than ACEIIINaming.

Old-age mental telehealth services at primary healthcare centers in low- resource areas in Greece: design, iterative development and single-site pilot study findings.

BACKGROUND: Even though communities in low-resource areas across the globe are aging, older adult mental and cognitive health services remain mainly embedded in tertiary- or secondary hospital settings, and thus not easily accessible by older adults living in such communities. Here, the iterative development of INTegRated InterveNtion of pSychogerIatric Care (INTRINSIC) services addressing the mental and cognitive healthcare needs of older adults residing in low-resource areas of Greece is depicted. METHODS: INTRINSIC was developed and piloted in three iterative phases: (i) INTRINSIC initial version conceptualization; (ii) A 5-year field testing in Andros island; and (iii) Extending the services. The INTRINSIC initial version relied on a digital platform enabling videoconferencing, a flexible battery of diagnostic tools, pharmacological treatment and psychosocial support and the active involvement of local communities in service shaping. RESULTS: Ιn 61% of the 119 participants of the pilot study, new diagnoses of mental and/or neurocognitive disorders were established. INTRINSIC resulted in a significant reduction in the distance travelled and time spent to visit mental and cognitive healthcare services. Participation was prematurely terminated due to dissatisfaction, lack of interest or insight in 13 cases (11%). Based on feedback and gained experiences, a new digital platform, facilitating e-training of healthcare professionals and public awareness raising, and a risk factor surveillance system were created, while INTRINSIC services were extended to incorporate a standardized sensory assessment and the modified problem adaptation therapy. CONCLUSION: The INTRINSIC model may be a pragmatic strategy to improve access of older adults with mental and cognitive disorders living in low-resource areas to healthcare services.

Life Satisfaction in a Clinical and a Nonclinical Group of Older People: The Role of Self-Compassion and Social Support.

Despite the health-promoting role of life satisfaction, little is known about its determining factors in older people with mental health problems compared to nonclinical participants. This study provides preliminary data into the role of social support, self-compassion, and meaning in life on older people's life satisfaction within both clinical and non-clinical populations. In total, 153 older adults (age ≥60) completed the Satisfaction With Life Scale (SWLS), the Self-Compassion Scale (SCS), the Meaning in Life Questionnaire (MLQ), and questions for relational variables. Hierarchical logistic regression analysis revealed that determinants of life satisfaction were self-kindness (B = 2.036, p = .001) and intimate friends' network (B = 2.725, p = .021), while family relationships were found to be significant among the clinical group (B = 4.556, p = .024). Findings are discussed in relation to incorporating self-kindness and rapport with family in clinical work with older adults to better promote their well-being.

The Differential Role of Executive Apathy in Alzheimer's Disease Dementia, Mild Cognitive Impairment and Healthy Cognitive Ageing.

The objective of the present work was to compare the levels of executive, emotional, and initiation apathy in individuals with mild cognitive impairment (MCI), mild Alzheimer's disease dementia (ADD), and cognitively intact healthy controls (HCs). Fifty-two patients with mild ADD, 40 individuals with MCI, and 37 cognitively intact individuals were included in the current study. The participants were consecutive visitors to the Outpatient Memory Clinic of "Nestor" Alzheimer's Center. The symptoms of apathy were measured with the dimensional apathy scale. Analyses showed that ADD patients had significantly higher degrees of executive, emotional, initiation, and overall apathy compared with both the MCI group and the HCs. Additionally, a significant difference was observed in the dimension of executive apathy between individuals with MCI and the HCs. In conclusion, the dimension of executive apathy was the most sensitive measure regarding the differentiation of individuals with mild ADD or MCI and HCs. Hence, detailed evaluation of executive apathy in older individuals referred to a memory clinic may provide useful information contributing to their diagnostic categorization and to the differentiation between neurocognitive disorders and healthy cognitive ageing.

Patient-reported Physical Function Is Associated With Survival After Lung Resection for Non-Small Cell Lung Cancer.

BACKGROUND: We investigated the association between preoperative quality of life and long-term survival in patients undergoing surgical resection for non-small cell lung cancer. METHODS: Retrospective analysis was conducted on 388 consecutive patients who completed the quality of life assessment through the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 and lung cancer specific module (LC13), before anatomic lung resection for non-small cell lung cancer (2014-2018). Survival distribution was estimated by the Kaplan-Meier method. Cox proportional hazards regression and competing risk regression analyses were used to assess the independent association of preoperative patient-reported outcomes with overall and cancer-specific survival. RESULTS: Higher score in patient-reported physical functioning was significantly associated with longer overall survival. Factors significantly associated with poorer overall survival remained older age (P = .005), low body mass index (P = .007), male sex (P < .001), and nodal involvement (P = .007). Competing regression analysis found that worse baseline lung cancer-specific dyspnea (P = .03), low body mass index (P = .01), worse performance status (P = .03), and lymph node involvement (P = .01) were significantly associated with poorer cancer-specific survival. CONCLUSIONS: Higher patient-reported physical function score was associated with longer overall survival after resection. Our study highlights the significance of routinely collecting quality of life data to aid preoperative decision making in non-small cell lung cancer.

Naming ability assessment in neurocognitive disorders: a clinician's perspective.

BACKGROUND: Detecting impaired naming capacity is valuable in diagnosing neurocognitive disorders (ND). A. clinical practice- oriented overview of naming tests validated in ND is not available yet. Here, features of naming tests with validated utility in ND which are open access or available for purchase are succinctly presented and compared. METHODS: Searches were carried out across Pubmed, Medline and Google Scholar. Additional studies were identified by searching reference lists. Only peer-reviewed journal articles were eligible. A narrative- and tabullar synthesis was used to summarize different aspects of the naming assessment instruments used in patients with ND such as stimuli type, administration time, assessment parameters and accessibility. Based on computational word frequency calculations, the tests were compared in terms of the average frequency of their linguistic content. RESULTS: Twelve naming tests, relying either on visual or auditory stimuli have been validated in ND. Their content and administration time vary between three and 60 items and one and 20 minutes, respectively. The average frequency of the words of each considered test was two or lower, pointing to low frequency of most items. In all but one test, scoring systems are exclusively based on correctly named items. Seven instruments are open access and four are available in more than one language. CONCLUSIONS: Gaining insights into naming tests' characteristics may catalyze the wide incorporation of those with short administration time but high diagnostic accuracy into the diagnostic workup of ND at primary healthcare and of extensive, visual or auditory ones into the diagnostic endeavors of memory clinics, as well as of secondary and tertiary brain healthcare settings.

A standardised methodology for the extraction and quantification of cell-free DNA in cerebrospinal fluid and application to evaluation of Alzheimer's disease and brain cancers.

Cerebrospinal fluid (CSF) is a source of diagnostic biomarkers for a range of neurological conditions. Cell-free DNA (cfDNA) is detected in CSF and differences in the concentration of cell-free mitochondrial DNA have been reported in studies of neurodegenerative disorders including Alzheimer's disease (AD). However, the influence of pre-analytical steps has not been investigated for cfDNA in CSF and there is no standardised approach for quantification of total cfDNA (copies of nuclear genome or mitochondria-derived gene targets). In this study, the suitability of four extraction methods was evaluated: QIAamp Circulating Nucleic Acid (Qiagen), Quick-cfDNA Serum & Plasma (Zymo), NucleoSnap® DNA Plasma (Macherey-Nagel) and Plasma/Serum Circulating DNA Purification Mini (Norgen) kits, for cfDNA extraction from CSF of controls and AD dementia patients, utilising a spike-in control for extraction efficiency and fragment size. One of the optimal extraction methods was applied to a comparison of cfDNA concentrations in CSF from control subjects, AD dementia and primary and secondary brain tumour patients. Extraction efficiency based on spike-in recovery was similar in all three groups whilst both endogenous mitochondrial and nucleus-derived cfDNA was significantly higher in CSF from cancer patients compared to control and AD groups, which typically contained < 100 genome copies/mL. This study shows that it is feasible to measure low concentration nuclear and mitochondrial gene targets in CSF and that normalisation of extraction yield can help control pre-analytical variability influencing biomarker measurements.

Alzheimer's disease research progress in the Mediterranean region: The Alzheimer's Association International Conference Satellite Symposium.

As research and services in the Mediterranean region continue to increase, so do opportunities for global collaboration. To support such collaborations, the Alzheimer's Association was due to hold its seventh Alzheimer's Association International Conference Satellite Symposium in Athens, Greece in 2021. Due to the COVID-19 pandemic, the meeting was held virtually, which enabled attendees from around the world to hear about research efforts in Greece and the surrounding Mediterranean countries. Research updates spanned understanding the biology of, treatments for, and care of people with Alzheimer's disease (AD_ and other dementias. Researchers in the Mediterranean region have outlined the local epidemiology of AD and dementia, and have identified regional populations that may expedite genetic studies. Development of biomarkers is expected to aid early and accurate diagnosis. Numerous efforts have been made to develop culturally specific interventions to both reduce risk of dementia, and to improve quality of life for people living with dementia.

The Effects of COVID-19 lockdown on neuropsychiatric symptoms in patients with dementia or mild cognitive impairment: A systematic review and meta-analysis.

The COVID-19 pandemic may have a disproportionate impact on people with dementia/mild cognitive impairment (MCI) due to isolation and loss of services. The aim of this systematic review was to investigate the effects of the COVID-19 lockdown on neuropsychiatric symptoms (NPS) in people living with dementia/MCI. Two authors searched major electronic databases from inception to June 2021 for observational studies investigating COVID-19 and NPS in people with dementia/MCI. Summary estimates of mean differences in NPS scores pre- versus post-COVID-19 were calculated using a random-effects model, weighting cases using inverse variance. Study quality and risk of bias were assessed by the Newcastle-Ottawa Scale. From 2730 citations, 21 studies including 7139 patients (60.0% female, mean age 75.6 ± 7.9 years, 4.0% MCI) with dementia were evaluated in the review. Five studies found no changes in NPS, but in all other studies, an increase in at least one NPS or the pre-pandemic Neuropsychiatric Inventory (NPI) score was found. The most common aggravated NPS were depression, anxiety, agitation, irritability, and apathy during lockdown, but 66.7% of the studies had a high bias. Seven studies including 420 patients (22.1% MCI) yielded enough data to be included in the meta-analysis. The mean follow-up time was 5.9 ± 1.5 weeks. The pooled increase in NPI score before compared to during COVID-19 was 3.85 (95% CI:0.43 to 7.27; P = 0.03; I2  = 82.4%). All studies had high risk of bias. These results were characterized by high heterogeneity, but there was no presence of publication bias. There is an increase in the worsening of NPS in people living with dementia/MCI during lockdown in the COVID pandemic. Future comparative studies are needed to elucidate whether a similar deterioration might occur in people without dementia/MCI.

Hospital workforce mental reaction to the pandemic in a low COVID-19 burden setting: a cross-sectional clinical study.

Τhe COVID-19 pandemic has mental health implications for both healthcare workforces and general population, particularly in regions heavily hit by the crisis. Τhe study aimed (i) to investigate anxiety- and depression severity differences between staff of a COVID-19 treatment unit (N = 84) and a hospital without such a unit (N = 55) in comparison to participants of a convenience general population online survey (N = 240) and (ii) to explore relations between such symptoms and hospital staff reaction to COVID-19 in a low COVID-19 burden setting. Anxiety was studied with the Generalized Anxiety Disorder 7-Item in hospital workforces and with the Hospital Anxiety Depression Scale (HADS) in online survey participants. Depression symptoms were assessed with the Patient Health Questionnaire-9 in hospital employees and the HADS in the online survey sample. Symptoms were classified as absent/minimal, borderline abnormal or indicating clinical caseness. Staff reaction to COVID-19 was tapped with a 9-item-questionnaire and the 22-item Impact of Event Scale-revised (IES-R). Proper tests for differences and stepwise ordered logistic regression models were employed. Anxiety- and depression severity was higher in hospital workforces than in online survey participants (P < 0.05). Anxiety was more severe in frontline- compared to backstage employees (P < 0.001) was inversely correlated with age (P = 0.011) and positively with avoidance (P = 0.028). Both anxiety and depression symptoms related to intrusion symptoms (P < 0.001). Regarding the relatively long data collection period, an inverse association between crisis duration and depression symptoms was detected (P = 0.025). These observations point to the urgent need for distress-mitigating interventions for hospital workforces even in low COVID-19 burden settings.

Validation of the Cognitive Telephone Screening Instruments COGTEL and COGTEL+ in Identifying Clinically Diagnosed Neurocognitive Disorder Due to Alzheimer's Disease in a Naturalistic Clinical Setting.

BACKGROUND: Telephone-based neurocognitive instruments embody valuable tools in identifying cognitive impairment in research settings and lately also in clinical contexts due to the pandemic crisis. The accuracy of the Cognitive Telephone Screening Instrument (COGTEL) in detecting mild- (MiND) and major (MaND) neurocognitive disorder has not been studied yet. OBJECTIVE: Comparison of the utility of COGTEL and COGTEL+, which is enriched with orientation items, with the modified Mini-Mental State Examination (3MS) in detecting MiND and MaND due to Alzheimer's disease (AD) and assessment of the impact of COGTEL face-to-face-versus telephone administration on individual performance. METHODS: The study included 197 cognitively intact individuals (CI), being at least 45 years old, 95 and 65 patients with MiND and MaND due to AD, respectively. In 20 individuals COGTEL was administered both in face-to-face and telephone sessions. Statistical analyses included proportional odds logistic regression models, stratified repeated random subsampling used to recursive partitioning to training and validation set (70/30 ratio), and an appropriate F-test. RESULTS: All studied instruments were significant predictors of diagnostic outcome, but COGTEL+ and 3MS explained more variance relative to the original COGTEL. Except for the validation regression models including COGTEL in which the average misclassification error slightly exceeded 15%, in all other cases the average misclassification errors (%) were lower than 15%. COGTEL administration modality was not related to systematic over- or underestimation of performance on COGTEL. CONCLUSION: COGTEL+ is a valuable instrument in detecting MiND and MaND and can be administered in face-to-face or telephone sessions.

Differences in cause and 12-month follow-up outcome of parkinsonian symptoms in depressed older adults treated with antipsychotics: a case series.

BACKGROUND: Parkinsonian symptoms are common adverse effects of antipsychotics. Older adults are particularly vulnerable to drug-induced parkinsonism. Nonetheless, parkinsonian symptoms in seniors treated with antipsychotics cannot be straightforwardly attributed to antipsychotic medication. A comprehensive diagnostic workup is necessary in many cases in order to shed light on the cause of such symptoms in this patient population. CASE SERIES: Eight cases of hospitalized depressed older adults with parkinsonian symptoms, who were treated for at least one year with antipsychotics, are reported. Based on neurological consultation, structural brain imaging and Ioflupane (I-123) dopamine transporter (DAT) single photon emission computerized tomography (SPECT), Parkinson's disease was diagnosed in one case, idiopathic tremor in another, vascular parkinsonism in another one, while in another individual parkinsonian symptoms persisted at 12-month post-discharge follow-up even though his/her symptoms were classified as drug-induced on discharge. In four patients, parkinsonian symptoms were definitely drug-induced and no movement disturbances were reported at follow-up. CONCLUSIONS: Differences in the cause and outcome of parkinsonian symptoms in seniors treated with antipsychotics merit systematic and in-depth study considering the therapeutic and prognostic implications of an accurate detection of the cause of such symptoms. Familiarizing clinical psychiatrists with these differences could pave the way towards approaching seniors with severe, atypical and/or persistent parkinsonian symptoms in a more individualized diagnostic and therapeutic manner, and towards more cautious prescribing of antipsychotics in this age group.

Psychological distress in the Greek general population during the first COVID-19 lockdown.

BACKGROUND: SARS-CoV-2 has rapidly spread worldwide, threatening public health and financial and social life. AIMS: The current study's aim was to determine the prevalence of psychological distress and post-traumatic stress symptoms in the Greek population during the first COVID-19 lockdown, and to detect potential correlates. METHOD: An anonymous online survey was conducted between 10 April and 4 May 2020, to collect information regarding people's psychological functioning and COVID-19-related perceptions. RESULTS: A total of 1443 individuals completed the survey; 293 (20%) reported clinically significant anxiety symptoms, 188 (12.9%) reported clinically significant depressive symptoms and 506 (36.4%) suffered from definite post-traumatic stress disorder. Anxiety symptoms were independently associated with female gender (ß = 1.281, 95% CI 0.808-1.755, P < 0.001), educational level (ß = -1.570, 95% CI -2.546 to -0.595, P = 0.002), perceived severity (ß = -1.745, 95% CI -3.146 to -0.344, P = 0.015) and COVID-19-related worry (ß = 7.633, 95% CI 6.206-9.060, P < 0.001). Depressive symptoms were strongly correlated with educational level (ß = -1.298, 95% CI -2.220 to -0.377, P = 0.006), perceived severity (ß = -1.331, 95% CI -2.579 to -0.082, P = 0.037) and COVID-19-related worry (ß = 4.102, 95% CI 2.769-5.436, P < 0.001). Finally, post-traumatic stress symptoms were linked to female gender (ß = 6.451, 95% CI 4.602-8.299, P < 0.001), educational level (ß = -5.737, 95% CI -9.479 to -1.996, P = 0.003), psychiatric history (ß = -4.028, 95% CI -6.274 to -1.782, P < 0.001) and COVID-19-related worry (ß = 23.865, 95% CI 18.201-29.530, P < 0.001). CONCLUSIONS: A significant percentage of the population reported clinically important anxiety, depressive and post-traumatic stress symptoms. Women, less-educated individuals and people with a psychiatric history appeared more vulnerable to the pandemic's psychological impact.
