Point and 5-year period prevalence of neuropsychiatric symptoms in dementia: The Cache county study

Abstract: Background Neuropsychiatric symptoms are nearly universal in dementia, yet little is known about their longitudinal course in the community. Objective To estimate point and 5-year period prevalence of neuropsychiatric symptoms in an incident sample of 408 dementia participants from the Cache County Study. Methods The Neuropsychiatric Inventory assessed symptoms at baseline and at 1.5 years, 3.0 years, 4.1 years, and 5.3 years. Point prevalence, period prevalence and mean symptom severity at each time point were estimated. Results Point prevalence for delusions was 18% at baseline and 34–38% during the last three visits; hallucinations, 10% at baseline and 19–24% subsequently; agitation/aggression fluctuated between 13% and 24%; depression 29% at baseline and 41–47% subsequently; apathy increased from 20% at baseline to 51% at 5.3 years; elation never rose above 1%; anxiety 14% at baseline and 24–32% subsequently; disinhibition fluctuated between 2% and 15%; irritability between 17% and 27%; aberrant motor behavior gradually increased from 7% at baseline to 29% at 5.3 years. Point prevalence for any symptom was 56% at baseline and 76–87% subsequently. Five-year period prevalence was greatest for depression (77%), apathy (71%), and anxiety (62%); lowest for elation (6%), and disinhibition (31%). Ninety-seven percent experienced at least one symptom. Symptom severity was consistently highest for apathy. Conclusions Participants were most likely to develop depression, apathy, or anxiety, and least likely to develop elation or disinhibition. Give converging evidence that syndromal definitions may more accurately capture neuropsychiatric co-morbidity in dementia, future efforts to validate such syndromes are warranted.

Anxiety and Depression in Later Life: Co-Occurrence and Communality of Risk Factors

Abstract: OBJECTIVE: The purpose of this study was to examine the comorbidity of and communality of risk factors associated with major depressive disorder and anxiety disorders in later life. METHOD: A random age- and sex-stratified community-based sample (N=3,056) of the elderly (age 55–85 years) in the Netherlands was studied. A two-stage screening design was used, with the Center for Epidemiologic Studies Depression Scale as a screening instrument and the National Institute of Mental Health Diagnostic Interview Schedule as a criterion instrument. Risk factors were measured with well-validated instruments and represented a broad range of vulnerability and stress-related factors associated with anxiety and depression. Multivariate analyses examined risk factors associated with pure major depressive disorder, pure anxiety disorders, and comorbid conditions. RESULTS: Comorbidity was highly prevalent: 47.5% of those with major depressive disorder also met criteria for anxiety disorders, whereas 26.1% of those with an...

The prevalence and meaning of fatigue in rheumatic disease.

Abstract: Objective. To determine the prevalence of fatigue in rheumatic disease ; to characterize the strength of associations between demographic and clinical features and fatigue ; to identify predictors of fatigue, and to determine the consequence of clinically significant fatigue. Methods. 1488 consecutive patients with rheumatic disease were assessed with the Clinical Health Assessment Questionnaire, a health status instrument with scales for fatigue, pain, global severity, sleep disturbance, gastrointestinal problems, anxiety, depression, health status, health satisfaction, and work ability. All patients underwent rheumatic disease examinations and laboratory testing. Results. Fatigue measured by visual analog scale (VAS) was present in 88-98% of patients, but clinically important levels of fatigue (≥ 2.0 on VAS) were present in more than 41% of patients with rheumatoid arthritis (RA) or osteoarthritis (OA) and 76% of those with fibromyalgia (FM). Fatigue was related to almost all demographic and clinical variables, but in multivariate analyses the strongest independent predictors of fatigue were pain, sleep disturbance, depression, tender point count and Health Assessment Questionnaire (HAQ) disability. About 90% of the R 2 of the model (all patients=0.51, RA=0.49, OA=0.45, FM=0.41) was explained by pain, sleep disturbance, and depression. In RA assessed by erythrocyte sedimentation rate, joint count and grip strength, no association of the inflammatory process with fatigue could be found in the multivariate analyses. In measuring health status, fatigue was strongly associated with work dysfunction and general measures of health (VAS of global severity, health status, and health satisfaction). Conclusion. Fatigue is common across all rheumatic diseases, associates with all measures of distress, and is a predictor of work dysfunction and overall health status. The correlates of fatigue are generally similar across RA, OA and FM. Fatigue assessment adds much to understanding and management of patients and diseases.

Psychomotor Symptoms of Depression

Abstract: Objective: The authors summarize current knowledge regarding the psychomotor symptoms of depression. Method: Findings from the objective quantification of psychomotor symptoms are reviewed, and methodological issues are considered. The contemporary empirical literature regarding the diagnostic, prognostic, and potential pathophysiologic significance of psychomotor symptoms is summarized. Results: It has been repeatedly shown that depressed patients differ from normal and psychiatric comparison groups with regard to objectively quantified gross motor activity, body movements, speech, and motor reaction time. Course of illness, diurnal variation, medication status, sex, and age are associated with agitation and retardation and should be controlled when one is studying psychomotor symptoms. Psychomotor symptoms in depression may have unique significance. They have high discriminative validity, may be the only symptoms of depression that distinguish depression subtypes, and are predictive of good response to tricyclic antidepressants. Results of brain imaging and biochemical studies link depression and motor symptoms to abnormalities in the basal ganglia and basal ganglia/thalamo-cortical circuits. Conclusions: The investigation of psychomotor disturbance in depression is specifically consistent with neo-Kraepelinian standards for the study of psychiatric disorders. Our current knowledge of psychomotor symptoms is conceptually obscure, yet a large body of evidence specifies their manifestation and supports their significance. Identifying the incidence of abnormal motor behaviors in depressed patients and assessing the component processes that accompany and determine their manifestation may be important advances in the study of psychomotor symptoms in depression.

Predictors of clinical recovery from concussion: a systematic review

Abstract: Objective A systematic review of factors that might be associated with, or influence, clinical recovery from sport-related concussion. Clinical recovery was defined functionally as a return to normal activities, including school and sports, following injury. Design Systematic review. Data sources PubMed, PsycINFO, MEDLINE, CINAHL, Cochrane Library, EMBASE, SPORTDiscus, Scopus and Web of Science. Eligibility criteria for selecting studies Studies published by June of 2016 that addressed clinical recovery from concussion. Results A total of 7617 articles were identified using the search strategy, and 101 articles were included. There are major methodological differences across the studies. Many different clinical outcomes were measured, such as symptoms, cognition, balance, return to school and return to sports, although symptom outcomes were the most frequently measured. The most consistent predictor of slower recovery from concussion is the severity of a person’s acute and subacute symptoms. The development of subacute problems with headaches or depression is likely a risk factor for persistent symptoms lasting greater than a month. Those with a preinjury history of mental health problems appear to be at greater risk for having persistent symptoms. Those with attention deficit hyperactivity disorder (ADHD) or learning disabilities do not appear to be at substantially greater risk. There is some evidence that the teenage years, particularly high school, might be the most vulnerable time period for having persistent symptoms—with greater risk for girls than boys. Conclusion The literature on clinical recovery from sport-related concussion has grown dramatically, is mostly mixed, but some factors have emerged as being related to outcome.
