Prevalence of and Factors Associated with Hypersexuality in Patients with Dementia: A Retrospective Cross-Sectional Study.

INTRODUCTION: The psychological and behavioral symptoms of dementia are frequently observed in clinical practice, and those related to sexuality are particularly challenging. However, few studies have evaluated the prevalence or factors associated with hypersexuality in patients with dementia. OBJECTIVES: This study aims to determine the prevalence of hypersexuality in patients with dementia, describe associated factors, and qualitatively report the most common presentations and treatments. METHODS: This retrospective cross-sectional study collected data from semi-structured charts of dementia patients who were followed up at a secondary care reference center between 2015 and 2019. Results: Of 552 total patients, 52 (9.3%) were hypersexual, which was associated with male sex (P < .000; OR 2.95, 95% CI 1.73-5.01), frontotemporal dementia (P < .007), alcohol use (P < .015; OR 2.35, 95% CI 1.16-4.73) and tobacco use (P < .000; OR 2.88, 95% CI 1.61-5.13). CONCLUSIONS: Although our findings were similar to the literature, their significant variability reflects the limited and low quality of the available evidence and a lack of standardization regarding terminology, definitions, and diagnostic criteria for hypersexuality.

Quality of life, cognitive and behavioural impairment in people with motor neuron disease: a systematic review.

PURPOSE: Motor neuron disease (MND) is a neurodegenerative disease, progressively impacting function and self-perceived quality of life (QoL). Up to 50% of people with MND can present with cognitive and behavioural impairment, with an associated increase in caregiver burden or strain. However, there has been no systematic exploration of the relationship between QoL and cognitive or behavioural impairment in MND. The aim was to determine if there is a relationship between QoL and cognitive/behavioural impairment in MND, while also supplementarily looking to determine the types of cognitive/behavioural and QoL measures utilised in these studies. METHODS: A systematic search was performed across multiple databases (PsychINFO, Embase, Medline, AMED) for research published up to the date of February 22, 2023. Studies utilising quantitative methods of measuring QoL, cognitive/behavioural functioning/impairment were included. Findings examining relationships between QoL-cognitive/behavioural impairment were extracted and synthesised. RESULTS: A total of 488 studies were identified, with 14 studies included in the systematic review. All 14 studies were observational (11 cross-sectional, 3 longitudinal). 13 studies utilised MND non-specific measures, particularly in relation to QoL and cognitive impairment. Of 8 studies measuring behavioural impairment 62.5% (N = 5) found either a lower QoL difference or association. Only 33.3% (N = 4) of 12 studies measuring cognitive impairment found a lower QoL difference or association. CONCLUSIONS: This systematic review shows that behavioural impairment may have an impact on QoL in MND. There is variability in types of assessments used to measure QoL and also cognitive/behavioural impairment, most of which are disease-non-specific. Recommendations for future research are to use comprehensive disease-specific, multidomain measures to further elucidate the QoL-cognitive/behavioural impairment relationship.

The effects of individual music therapy in nursing home residents with dementia to improve general well-being: study protocol of a randomized controlled trial.

BACKGROUND: Dementia is often associated with Neuropsychiatric Symptoms (NPS) such as agitation, depression, hallucinations, anxiety, that can cause distress for the resident with dementia in long-term care settings and can impose emotional burden on the environment. NPS are often treated with psychotropic drugs, which, however, frequently cause side effects. Alternatively, non-pharmacological interventions can improve well-being and maintain an optimal quality of life (QoL) of those living with dementia. Other QoL related outcomes, such as pain, discomfort and sleep disruption are relevant outcomes in music trials as well. Music therapy is a non-pharmacological intervention that can reduce NPS and improve well-being, and its associated symptoms in dementia. METHODS: The research will be conducted at eight nursing home facilities of a health care organization in the Netherlands. A sample size of 30 in each group (experimental and control group) is required, totalling 60 residents increased to 80 when considering expected drop out to follow up. The participants in the intervention group receive 30 min of individual music therapy (MT) in their own room by a music therapist twice a week for 12 weeks. The participants in the control group will receive 30 min of individual attention in their own room by a volunteer twice a week for 12 weeks. Assessments will be done at baseline, 6 weeks and 12 weeks. An independent observer, blinded for the intervention or control condition, will assess directly observed well-being (primary outcome) and pain (secondary outcome) before and after the sessions. Nurses will assess other secondary outcomes unblinded, i.e., perceived quality of life and NPS, both assessed with validated scales. The sleep duration will be indirectly assessed by a wrist device called MotionWatch. Information about psychotropic drug use will be derived from electronic medical chart review. DISCUSSION: The main purpose of this study is to assess the effects of individual music therapy on directly observed well-being controlled for individual attention in nursing home residents with dementia with NPS. The outcomes refer to both short-term and long-term effects consistent with therapeutic goals of care for a longer term. We hope to overcome limitations of previous study designs such as not blinded designs and music facilitators that were not only music therapists but also occupational therapists and nurses. This study should lead to more focused recommendations for practice and further research into non-pharmacological interventions in dementia such as music therapy. TRIAL REGISTRATION: The trial is registered at the International Clinical Trials Registry Platform (ICTRP) search portal in the Netherlands Trial Registration number NL7708, registration date 04-05-2019.

Examining pain, function, behavioral symptoms and associations with engagement in meaningful activity for residents with dementia in assisted living.

OBJECTIVES: The purpose of this study was to examine factors associated with engagement in meaningful activity among residents with dementia in assisted living. We hypothesized that greater functional independence, less pain, and lower behavioral and psychological symptom severity would be associated with higher engagement in meaningful activity after controlling for residents' age, gender, comorbidities, and cognition. Understanding factors associated with engagement in meaningful activity can help to inform strategies for optimizing engagement among residents with dementia in assisted living. METHOD: This descriptive study used baseline data from a randomized controlled trial, Meaningful Activity for Managing Behavioral Symptoms of Distress (MAC-4-BSD). Linear regression was used to examine factors associated with engagement in meaningful activity. RESULTS: A total of 71 residents from 5 assisted living settings were included in the sample. Most participants were female (n = 52, 73%), White (n = 62, 87%), and mean age was 85 years old (SD = 8.2). Controlling for age, gender, comorbidities, and cognition, pain was significantly associated with engagement in meaningful activity (b= -2.09, p < 0.05). There were no associations found between function and behavioral symptoms with engagement in meaningful activity. CONCLUSION: Findings from this study show that pain is a significant factor that is negatively associated with residents' engagement in meaningful activity. Ongoing research is needed to help improve pain management for residents with dementia in assisted living and support their engagement in meaningful activity.

Validation of the French COVID-Related Thoughts and Behavioral Symptoms Questionnaire (Cov-Tabs): A self-report assessment.

OBJECTIVES: The COVID-Related Thoughts and Behavioral Symptoms (Cov-Tabs) is a self-reported questionnaire developed to identify the presence of psychological distress and anxiety-related behavior associated with COVID-19. This scale has been used since the first episodes of mass contamination of COVID-19 disease in the USA without psychometric validation analysis. The objective of this paper is to validate the French version of the Cov-TaBS. METHOD: In this study, we assessed a French translation of Cov-Tabs in 300 subjects from the general population. Moreover, we assessed convergent and discriminant validities using an anxiety and depression scale and a paranoid ideation scale. Statistical analyses consisted of evaluating internal consistency, test-retest reliability, and construct validity as well. RESULTS: The French translation of the Cov-Tabs demonstrated high internal consistency and reliability, as well as good temporal stability over a period of less than 2 weeks. It also showed strong convergent validity with anxiety and depression traits and divergent validity with paranoid ideation. CONCLUSION: Our study indicates that the French version of the Cov-Tabs has robust psychometric properties and is a valid tool for evaluating behavioral symptomatology and thoughts related to COVID-19 disease. Therefore, the French version of the Cov-Tabs is a valid tool that can be used in French-speaking individuals.

Network Analysis of Comorbid Depressive and Anxious Symptoms in Family Caregivers of People with Dementia.

OBJECTIVES: The aim of this study is an in-depth approach to depressive-anxious comorbidity in caregivers according to stress reactivity to disruptive behaviors using network analysis. METHODS: The sample was composed of 317 primary family caregivers recruited through Day Care Centers and Neurology Services. The sample was split into low and high stress reactivity groups, based on their reports of reaction to disruptive behaviors. Depressive and anxious symptoms, daily hours dedicated to caregiving, time of caring, frequency of disruptive behaviors, co-residence, and kinship were also cross-sectionally measured. RESULTS: The sample had a mean age of 62.38 years (SD = 12.97) and 68.5% were women. Regarding the network analysis, while the low reactivity group presents a sparse network, with no connection between anxious and depressive symptoms, the high reactivity group shows a high connection of intra and intercategory symptoms, with apathy, sadness, feeling depressed, and tension being the bridge symptoms between disorders. CONCLUSIONS: Caregivers' stress reaction to disruptive behaviors might be a key factor for understanding comorbidity between depressive and anxious symptoms. CLINICAL IMPLICATIONS: Tension, apathy, sadness, and feeling depressed should be clinical targets in the interventions, as they act as bridge symptoms between anxious and depressive symptomatology.

[Supporting psychobehavioral disorders at home and in institutions: a systemic approach]. / Accompagner les troubles psycho-comportementaux à domicile et en institution : une approche systémique.

Caring for people with Alzheimer's disease and related disorders is a complex process, that of a chronic illness. Psychological and behavioral symptoms associated to dementia can appear in all neuro-degenerative diseases to varying degrees, and depend on numerous factors that need to be understood in order to take appropriate action. We propose a systemic approach to psychological and behavioral symptoms, with a view to preventing their onset or reducing their severity.

Neurochemical, histological, and behavioral profiling of the acute, sub-acute, and chronic MPTP mouse model of Parkinson's disease.

Parkinson's disease (PD) is a heterogeneous multi-systemic disorder unique to humans characterized by motor and non-motor symptoms. Preclinical experimental models of PD present limitations and inconsistent neurochemical, histological, and behavioral readouts. The 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model of PD is the most common in vivo screening platform for novel drug therapies; nonetheless, behavioral endpoints yielded amongst laboratories are often discordant and inconclusive. In this study, we characterized neurochemically, histologically, and behaviorally three different MPTP mouse models of PD to identify translational traits reminiscent of PD symptomatology. MPTP was intraperitoneally (i.p.) administered in three different regimens: (i) acute-four injections of 20 mg/kg of MPTP every 2 h; (ii) sub-acute-one daily injection of 30 mg/kg of MPTP for 5 consecutive days; and (iii) chronic-one daily injection of 4 mg/kg of MPTP for 28 consecutive days. A series of behavioral tests were conducted to assess motor and non-motor behavioral changes including anxiety, endurance, gait, motor deficits, cognitive impairment, circadian rhythm and food consumption. Impairments in balance and gait were confirmed in the chronic and acute models, respectively, with the latter showing significant correlation with lesion size. The sub-acute model, by contrast, presented with generalized hyperactivity. Both, motor and non-motor changes were identified in the acute and sub-acute regime where habituation to a novel environment was significantly reduced. Moreover, we report increased water and food intake across all three models. Overall, the acute model displayed the most severe lesion size, while across the three models striatal dopamine content (DA) did not correlate with the behavioral performance. The present study demonstrates that detection of behavioral changes following MPTP exposure is challenging and does not correlate with the dopaminergic lesion extent.

Neuropsychiatric symptoms after moderate-to-severe traumatic brain injury in Vietnam: Assessment, prevalence, and impact on caregivers.

OBJECTIVE: Neuropsychiatric symptoms (NPSs) after moderate-to-severe traumatic brain injury (TBI) have been well documented in WEIRD (Western, educated, industrialized, rich, and democratic) populations. In non-WEIRD populations, such as Vietnam, however, patients with TBI clinically remain uninvestigated with potential neuropsychiatric disorders, limiting on-time critical interventions. This study aims to (1) adapt the Vietnamese Neuropsychiatric Inventory (V-NPI), (2) examine NPSs after moderate-to-severe TBI and (3) evaluate their impact on caregiver burden and well-being in Vietnam. METHOD: Caregivers of seventy-five patients with TBI completed the V-NPI, and other behavior, mood, and caregiver burden scales. RESULTS: Our findings demonstrated good internal consistency, convergent validity, and structural validity of the V-NPI. Caregivers reported that 78.7% of patients with TBI had at least three symptoms and 16.0% had more than seven. Behavioral and mood symptoms were more prevalent (ranging from 44.00% to 82.67% and from 46.67% to 66.67%, respectively) and severe in the TBI group. Importantly, NPSs in patients with TBI uniquely predicted 55.95% and 33.98% of caregiver burden and psychological well-being, respectively. CONCLUSION: This study reveals the first evidence for the presence and severity of NPSs after TBI in Vietnam, highlighting an urgent need for greater awareness and clinical assessment of these symptoms in clinical practice. The adapted V-NPI can serve as a useful tool to facilitate such assessments and interventions. In addition, given the significant impact of NPS on caregiver burden and well-being, psychosocial support for caregivers should be established.

Frequency and Pathophysiology of Apathy in Huntington Disease: A Systematic Review and Meta-Analysis.

OBJECTIVE: Apathy is a common behavioral symptom of Huntington disease (HD). This systematic review describes current evidence on the pathophysiology, assessment, and frequency of apathy in HD. METHODS: This systematic review was conducted in accordance with PRISMA guidelines. Using a comprehensive search strategy, the investigators searched the MEDLINE, Embase, and PsycINFO databases. All studies that evaluated apathy in HD patients with a valid scale and reported apathy frequency or scores were included. Apathy scores were analyzed by mean or standardized mean differences in accordance with Cochrane guidelines. RESULTS: A total of 1,085 records were screened and 80 studies were ultimately included. The Problem Behaviors Assessment-Short was the most frequently used apathy assessment tool. Apathy frequency generally ranged from 10%-33% in premanifest HD to 24%-76% in manifest HD. A meta-analysis of 5,311 records of patients with premanifest HD showed significantly higher apathy scores, with a standardized mean difference of 0.41 (CI=0.29-0.52; p<0.001). A comparison of 1,247 patients showed significantly higher apathy scores in manifest than premanifest HD, with a mean difference of 1.87 (CI=1.48-2.26; p<0.001). There was evidence of involvement of various cortical and subcortical brain regions in HD patients with apathy. CONCLUSIONS: Apathy was more frequent among individuals with premanifest HD compared with those in a control group and among individuals with manifest HD compared with those with premanifest HD. Considering the complexity and unique pattern of development in neurodegenerative disease, further studies are required to explore the pathophysiology of apathy in HD.

Cognitive-behavioral rehabilitation in patients with cardiovascular diseases: a randomized controlled trial (CBR-CARDIO, DRKS00029295).

BACKGROUND: Depression, generalized and cardiac anxiety, and posttraumatic stress disorder negatively affect disease severity, participation, and mortality in patients with cardiovascular disease. Psychological treatments within cardiac rehabilitation may improve the outcomes of these patients. We therefore developed a cognitive-behavioral rehabilitation program for patients with cardiovascular disease and mild or moderate mental illness or stress or exhaustion. In Germany, similar programs are well established in musculoskeletal rehabilitation and cancer rehabilitation. However, no randomized controlled trials have evaluated if such programs achieve better outcomes in patients with cardiovascular disease compared with standard cardiac rehabilitation. METHODS: Our randomized controlled trial compares cognitive-behavioral cardiac rehabilitation with standard cardiac rehabilitation. The cognitive-behavioral program complements standard cardiac rehabilitation with additional psychological and exercise interventions. Both rehabilitation programs last for four weeks. We enroll 410 patients with cardiovascular disease and mild or moderate mental illness or stress or exhaustion aged 18 to 65 years. Half of the individuals are randomly assigned to cognitive-behavioral rehabilitation and the other half to standard cardiac rehabilitation. Our primary outcome is cardiac anxiety 12 months after the end of rehabilitation. Cardiac anxiety is assessed with the German 17-item version of the Cardiac Anxiety Questionnaire. Secondary outcomes cover outcomes assessed by clinical examinations and medical assessments and a range of patient-reported outcome measures. DISCUSSION: This randomized controlled trial is designed to determine the effectiveness of cognitive-behavioral rehabilitation at decreasing cardiac anxiety in patients with cardiovascular disease and mild or moderate mental illness or stress or exhaustion. TRIAL REGISTRATION: German Clinical Trials Register (DRKS00029295, June 21, 2022).

Mental health among bereaved youth in the ALSPAC birth cohort: Consideration of early sociodemographic precursors, cognitive ability, and type of loss.

BACKGROUND: Bereaved youth are at greater risk for adverse mental health outcomes, yet less is known about how social context shapes health for bereaved children. Ecosocial theory is employed to conceptualize bereavement in the context of sociodemographic factors. METHOD: This longitudinal study used data from the Avon Longitudinal Study of Parents and Children. Of the 15,454 pregnancies enrolled, 5050 youth were still enrolled at age 16.5 and completed self-report questionnaires on life events and emotional/behavioral symptoms. RESULTS: Sociodemographic precursors associated with parent, sibling, or close friend bereavement included maternal smoking, parental education levels, and financial difficulties. The significant yet small main effect of higher cognitive ability, assessed at age 8, on reduced emotional/behavioral symptoms at age 16.5 (ß = -0.01, SE = 0.00, p < 0.001) did not interact with bereavement. Bereavement of a parent, sibling, or close friend was associated with a 0.19 point higher emotional/behavioral symptom log score compared to non-bereaved youth (95% CI: 0.10-0.28), across emotional, conduct, and hyperactivity subscales. CONCLUSIONS: Descriptive findings suggest sociodemographic precursors are associated with bereavement. While there was an association between the bereavement of a parent, sibling, or close friend and elevated emotional/behavioral symptoms, cognitive ability did not moderate that effect.

Diagnosis of behavioral symptoms as a predictor of institutionalization among Medicaid patients with dementia.

OBJECTIVES: Behavioral symptoms are commonly observed in the course of dementia. This study aimed to assess the association of the diagnosis of a cluster of behavioral symptoms (e.g., agitation, aggression, psychotic symptoms, and delirium/wandering) with the likelihood of subsequent institutionalization. METHODS: A retrospective cohort study of adults aged 65 and above diagnosed with dementia identified in the IBM® MarketScan® Multistate Medicaid database between October 01, 2015, and September 30, 2019, was conducted. The index date was defined as the first diagnosis date of dementia. The presence or absence of behavioral symptoms was identified in the 6 months prior to the index date (baseline). Institutionalization was evaluated 12 months (follow-up) post the index date. The association between diagnosed behavioral symptoms during the baseline period and institutionalization in the follow-up period was assessed using a multivariable logistic regression, adjusting for baseline sociodemographic and clinical characteristics. RESULTS: The study cohort included 40,714 patients with dementia. A diagnosis of behavioral symptoms was found among 2,067 (5.1%) patients during the baseline period. An increased likelihood of institutionalization was found during the follow-up among patients with agitation and aggression in baseline (OR = 1.51 (95% CI: 1.18-1.92)) compared to patients without these symptoms at baseline. Patients with psychotic symptoms in baseline had significantly higher odds of getting institutionalized during the follow-up compared to patients without psychotic symptoms in baseline (OR = 1.36 (95% CI: 1.20-1.54)). Similarly, patients with symptoms of delirium and wandering in baseline had a higher likelihood of institutionalization than patients without these symptoms at baseline (OR = 1.61 (95% CI: 1.30-1.99)). CONCLUSION: Several diagnosed behavioral symptoms were associated with a higher risk of institutionalization among older adults with dementia and should be considered when planning treatment strategies for the effective management of the condition.

Economic outcomes associated with diagnosed behavioral symptoms among patients with dementia in the United States: a health care claims database analysis.

BACKGROUND: Behavioral symptoms are common in patients with dementia. However, there is limited evidence of their economic burden. Among commercially insured patients with dementia in the United States, this study assessed the prevalence of diagnosed behavioral symptoms and whether healthcare resources utilization and costs were associated with these symptoms. METHODS: This retrospective observational study was conducted using the IBM® MarketScan® Commercial Claims and Encounters and Medicare Supplemental database from October 1, 2015, to September 30, 2019. Diagnoses of dementia and behavioral symptoms were identified using the International Classification of Diseases, 10th Modification codes. To test differences in patient characteristics among those with and without diagnosed behavioral symptoms, t-tests were used for continuous variables, and chi-square tests were used for categories. Generalized linear models were used to compare healthcare resource utilization and costs between patients with and without diagnosed behavioral symptoms, adjusted for baseline characteristics. RESULTS: Of the 62,901 patients with dementia included in the analysis, 16.5% had diagnosed behavioral symptoms 12 months post dementia diagnosis. Patients with diagnosed behavioral symptoms used more health care resources (mean annual pharmacy visits per patient: 39.83 vs. 33.08, mean annual outpatient visits per patient: 24.20 vs. 16.94, mean annual inpatient visits per patient: 0.98 vs. 0.47, mean annual ER visits per patient: 2.45 vs. 1.21) and incurred higher cost of care than those without diagnosed behavioral symptoms (mean annual total health care costs per patients: $63,268 versus $33,383). Inpatient care was the most significant contributor to total costs (adjusted annual mean cost per patient: $28,195 versus $12,275). CONCLUSION: Behavioral symptoms were significantly associated with higher healthcare resource utilization and costs among patients with dementia. Further research is warranted to address the unmet medical needs of this patient population.

The relationship between daily stressors, social support, depression and anxiety among dementia family caregivers: a micro-longitudinal study.

Objectives: This study aimed to examine the relationships between daily stress, social support, and the mental health of dementia family caregivers.Methods: A national sample of family caregivers (N = 165) completed daily diary surveys over 21 days (n = 2,841). Mixed-level models were used to examine the daily odds of experiencing depression and anxiety-related symptoms when risk factors, such as the stress of managing behavioral symptoms of dementia (BSDs) exhibited by the person living with dementia, and protective factors, such as social support, were reported on a given day.Results: Dementia caregivers were more likely to report depression and anxiety-related symptoms when BSDs were present and perceived as more bothersome than usual. Specific BSDs, including restless behaviors and intense emotions, were also found to increase the daily odds of experiencing depression and anxiety symptoms. The daily odds of depression symptoms decreased on days when caregivers reported receiving instrumental support, while the daily odds of anxiety symptoms increased on days when caregivers reported receiving emotional support.Conclusions: The daily odds of experiencing depression and anxietyvary based on the presence of specific BSDs and social support. These findings support the need for targeted interventions to improve the day-to-day well-being of dementia family caregivers.

Reminiscence music intervention on cognitive, depressive, and behavioral symptoms in older adults with dementia.

This study aimed to examine the efficacy and feasibility of a reminiscence music therapy program on improving cognition and decreasing depressive and behavioral symptoms in older adults with dementia. Participants in the reminiscence music therapy group participated in 60-minute reminiscence music therapy twice a week over a period of 4 weeks. Control group received usual care. Results showed that the intervention group exhibited a significant decrease in depressive symptoms compared to the control group (B=-5.30, p=.003). The reminiscence music therapy program exerted non-significant effects on cognition and behavioral symptoms in patients with dementia (p>.05). High adherence (96%) and positive participation data indicated that this reminiscence music program is feasible for people with dementia. Healthcare professionals in community or geriatric care units can create supportive environments and conduct regular reminiscence music activities that are related to festival features and reminiscence music for older adults with dementia to reduce depressive symptoms.

Internalizing and externalizing behaviors in high school adolescents in a northern border city of Mexico and their type of family.

OBJECTIVE: Identify externalizing and internalizing behaviors in high school adolescents in three schools in a northern border city in Mexico and their type of family. DESIGN: Cross-sectional survey. LOCATION: Three schools in the city of Tijuana, Mexico: two public and one private. PARTICIPANTS: 454 baccalaureate students 14-19 years old. MAIN MEASUREMENTS: We utilized Youth Self Report Scale, adapted and validated in Spanish, that measure internalization behaviors (anxiety, depression, isolation or somatic complaints), and externalization behaviors (verbal aggressiveness, delinquent behavior and attention-seeking). For dichotomous discrimination between deviant and nondeviant scores, we use the borderline clinical range by classifying YSR scale's T scores≥60, and to analyze the relationship between behavior problems or competencies and living or not in a nuclear family we utilized multiple logistic regression. RESULTS: 55% were female, mean age 16.4 years±0.98, and 62.3% came from a nuclear family. Prevalence of internalizing behaviors was 15.6%, and externalizing behaviors 14.8%. Women had statistically higher mean scores in depressive, anxious and verbally aggressive behavior, somatic complaints, and thought problems. The prevalence of internalizing behaviors in adolescents with nuclear family was 11.7% (n=33), and for adolescents with another type of family was 22.2% (n=38), OR 2.17 (CI 95% 1.30-3.61, p=0.003), but no differences was observed for externalizing behaviors and family type. When adjusted for sex, age, and public or private school, internalizing behaviors and specifically depressive behavior remained significant. CONCLUSIONS: We detected a moderate prevalence of internalizing behaviors in Mexican adolescents, predominantly among women, and also observed that not living with a nuclear family increases the odds of presenting internalizing behaviors. It is important that parents, teachers, and healthcare workers remain vigilant to detect these problems in a timely manner and develop interventions to improve the mental health and well-being of adolescents.

Neuropsychiatry and Neuropsychopharmacology of Dementia: a Guide to Evaluation, Diagnosis, and Management.

In the present study, I provide an examination of the neuropsychiatric approach to patients with various types of dementia, including Alzheimer's disease, Parkinson's disease dementia, Lewy body dementia, vascular dementia, frontotemporal dementia, and more. With a focus on the intersection of psychiatry and neurology, this paper underscores the importance of comprehensive neuropsychiatric evaluation, rigorous diagnosis, and evidence-based management. The paper delineates the neuropsychiatric manifestations specific to each type of dementia and explores both non-pharmacological and pharmacological management strategies, aiming to equip psychiatrists with the latest evidence-based approaches. Case studies are included to demonstrate real-world clinical scenarios and to provide insights into the practical application of the theories discussed. Additionally, this guide addresses current challenges in the neuropsychiatric approach to dementia and highlights potential solutions and future research directions. The primary objective of this guide is to enable psychiatrists to enhance the quality of life for individuals living with dementia by improving understanding, diagnosis, and management of the neuropsychiatric aspects of these conditions.

Effects of Client-Centered Occupational Therapy on Behavioral Psychological Symptoms, Social Interaction, Occupational Performance, Quality of Life, and Caregiver Burden among the Individuals with Dementia.

This study aimed to verify the effects of client-centered occupational therapy on individuals with dementia. Twenty participants were randomly assigned to an experimental group (client-centered occupational therapy) and a control group (general occupational therapy). A pretest, post-test, and follow-up tests were used to compare the effects of the intervention. The experimental group had significant changes in all variables, and the control group showed significant differences in verbal social interaction, quality of life, and burden of caregivers (p < 0.05). As a result of repeated measurement variance analysis, it was found that there was a significant effect within the group except for the NPI-Q distress items (p < 0.05), but the effect was not verified in all areas between the groups. Client-centered customized occupational therapy can be more effective than general occupational therapy in problem behavior, social interaction, quality of life, caregiver burden, and occupational performance of individuals with dementia.

The severity of neuropsychiatric symptoms is higher in early-onset than late-onset Alzheimer's disease.

BACKGROUND AND PURPOSE: The faster rates of cognitive decline and predominance of atypical forms in early-onset Alzheimer's disease (EOAD) suggest that neuropsychiatric symptoms could be different in EOAD compared to late-onset AD (LOAD); however, prior studies based on non-biomarker-diagnosed cohorts show discordant results. Our goal was to determine the profile of neuropsychiatric symptoms in EOAD and LOAD, in a cohort with biomarker/postmortem-confirmed diagnoses. Additionally, the contribution of co-pathologies was explored. METHODS: In all, 219 participants (135 EOAD, 84 LOAD) meeting National Institute on Aging and Alzheimer's Association criteria for AD (115 amyloid positron emission tomography/cerebrospinal fluid biomarkers, 104 postmortem diagnosis) at the University of California San Francisco were evaluated. The Neuropsychiatric Inventory-Questionnaire (NPI-Q) was assessed at baseline and during follow-up. The NPI-Q mean comparisons and regression models adjusted by cognitive (Mini-Mental State Examination) and functional status (Clinical Dementia Rating Sum of Boxes) were performed to determine the effect of EOAD/LOAD and amnestic/non-amnestic diagnosis on NPI-Q. Regression models assessing the effect of co-pathologies on NPI-Q were performed. RESULTS: At baseline, the NPI-Q scores were higher in EOAD compared to LOAD (p < 0.05). Longitudinally, regression models showed a significant effect of diagnosis, where EOAD had higher NPI-Q total, anxiety, motor disturbances and night-time behavior scores (p < 0.05). No differences between amnestics/non-amnestics were found. Argyrophilic grain disease co-pathology predicted a higher severity of NPI-Q scores in LOAD. CONCLUSIONS: Anxiety, night-time behaviors and motor disturbances are more severe in EOAD than LOAD across the disease course. The differential patterns of neuropsychiatric symptoms observed between EOAD/LOAD could suggest a pattern of selective vulnerability extending to the brain's subcortical structures. Further, co-pathologies such as argyrophilic grain disease in LOAD may also play a role in increasing neuropsychiatric symptoms.
