The longitudinal course of anxiety, depression and apathy through two years after stroke.

OBJECTIVE: Estimate the prevalence of anxiety disorders, depressive disorders and apathy two years after stroke, examine their longitudinal course, describe the course of psychological distress through two years after stroke, and evaluate Hospital Anxiety and Depression Scale HADS-A and HADS-D cut-off scores of ≥4 and ≥ 8 for detection of anxiety and depressive disorders two years after stroke. METHODS: In a longitudinal cohort study of 150 consecutive stroke patients in a stroke unit, 103 were assessed four months and 75 two years after stroke. Anxiety and depression disorders and symptoms were assessed by the Structured Clinical Interview for DSM-IV and HADS, apathy by the Apathy Evaluation Scale. RESULTS: Prevalence of at least one anxiety disorder or one depressive disorder decreased from four months to two years (23% vs 9%, P = 0.026, 19% vs 10%, P = 0.17). Apathy remained stable at 48% vs 50%. After two years, 80%, 79% and 19% of those with anxiety, depression or apathy at four months had recovered. Recovery-rates among patients with anxiety were 83% for panic disorder, 60% for generalized anxiety disorder (GAD), and 50% for social phobia. CONCLUSIONS: In contrast to apathy, recovery from anxiety and depression was high. About half of the patients with GAD, social phobia or agoraphobia did not recover. Co-morbid depression and apathy at four months implied a high risk for not recovering at two years. HADS-A and HADS-D cut-off scores of ≥8 were feasible for detection of anxiety and depression disorders two years after stroke.

Early detection of patients at risk for anxiety, depression and apathy after stroke.

BACKGROUND AND PURPOSE: The aim of this study was to identify clinical factors in the acute stage that can predict anxiety, depression and apathy at 4 months after stroke. METHODS: One hundred four consecutive stroke patients in a stroke unit were assessed within the first 2 weeks and after 4 months. Assessments included anxiety and depression symptoms on the Hospital Anxiety and Depression Scale (HADS) [HADS Anxiety subscale (HADS-A) > or = 8 and HADS Depression subscale (HADS-D) > or = 8], physical impairment, functional disability, somatic comorbidity upon admission, assessment of apathy (score > or = 34 on the Apathy Evaluation Scale) and a psychiatric Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnosis of anxiety disorder (anxiety) or depression (depression) on follow-up. Logistic regression analysis was used to identify factors associated with anxiety, depression and apathy. RESULTS: Anxiety and depression at 4 months were significantly associated with HADS-A scores of > or = 8 upon admission [odds ratio (OR)=4.4; 95% confidence interval (95% CI)=1.7-11.9; P=.003 and OR=2.9; 95% CI=1.0-7.9; P=.043, respectively]. Apathy at 4 months was significantly associated with somatic comorbidity upon admission (OR=3.0; 95% CI=1.0-8.3; P=.036) and had a borderline association with HADS-D scores of > or = 8 (OR=8.4; 95% CI=1.0-72.0; P=.051) upon admission. CONCLUSION: Assessment with HADS within the first 2 weeks of stroke can contribute to the detection of patients at risk for clinically significant anxiety, depression and apathy at 4 months after stroke.

Screening for anxiety and depression after stroke: comparison of the hospital anxiety and depression scale and the Montgomery and Asberg depression rating scale.

OBJECTIVE: Anxiety and depression after stroke are frequent, but are often overlooked and not assessed. The aims of the study were to (1) assess the prevalence of anxiety and depression and (2) compare the performance of the Hospital Anxiety and Depression Scale (HADS) and Montgomery and Asberg Depression Rating Scale (MADRS) as screening instruments for anxiety and depression disorders 4 months after stroke. METHODS: Stroke patients, consecutively admitted to a stroke unit, were assessed with HADS and MADRS 4 months after stroke (n=104). Depression and anxiety disorders were diagnosed using the Structured Clinical Interview for DSM-IV (SCID). Measures were compared in terms of correlations, sensitivity, specificity, positive and negative predictive value, overall agreement, kappa, and ROC curves, using DSM-IV diagnoses of "at least one current significant anxiety disorder" (Anxiety) and "any current depression" (Depression), as the clinical criteria. RESULTS: Anxiety occurred in 23% of patients and Depression in 19% (13% major depression, 3% minor depression, 4% dysthymia). For Anxiety, the optimal screening cut-off was 4 for HADS-A and 6 for HADS-total; for Depression, optimal cut-offs were 4 for HADS-D, 11 for HADS-total, and 8 for MADRS. At cut-offs commonly used in clinical practice for depression screening (HADS-D: 8, MADRS: 12), the MADRS performed marginally better than the HADS. CONCLUSION: Anxiety is as prevalent as depression 4 months after stroke. MADRS and HADS-D perform acceptably as screening instruments for depression, and HADS-A for anxiety after stroke. However, lower HADS cut-offs than recommended for the general population should be considered for stroke patients.

Mental health consultations in a prison population: a descriptive study.

BACKGROUND: The psychiatric morbidity among prison inmates is substantially higher than in the general population. We do, however, have insufficient knowledge about the extent of psychiatric treatment provided in our prisons. The aim of the present study was to give a comprehensive description of all non-pharmacological interventions provided by the psychiatric health services to a stratified sample of prison inmates. METHODS: Six medium/large prisons (n = 928) representing 1/3 of the Norwegian prison population and with female and preventive detention inmates over-sampled, were investigated cross-sectionally. All non-pharmacological psychiatric interventions, excluding pure correctional programs, were recorded. Those receiving interventions were investigated further and compared to the remaining prison population. RESULTS: A total of 230 of the 928 inmates (25 %) had some form of psychiatric intervention: 184 (20 %) were in individual psychotherapy, in addition 40 (4 %) received ad hoc interventions during the registration week. Group therapy was infrequent (1 %). The psychotherapies were most often of a supportive (62 %) or behavioural-cognitive (26 %) nature. Dynamic, insight-oriented psychotherapies were infrequent (8 %). Concurrent psychopharmacological treatment was prevalent (52 %). Gender and age did not correlate with psychiatric interventions, whereas prisoner category (remanded, sentenced, or preventive detention) did (p < 0.001). Most inmates had a number of defined problem areas, with substance use, depression, anxiety, and personality disorders most prevalent. Three percent of all inmates were treated for a psychotic disorder. Remand prisoners averaged 14 sessions per week per 100 inmates, while sentenced inmates and those on preventive detention averaged 22 and 25 sessions per week per 100 inmates, respectively. Five out of six psychiatric health services estimated the inmates' psychiatric therapy needs as adequately met, both overall and in the majority of individual cases. CONCLUSION: Our results pertain only to prisons with adequate primary and mental health services and effective diversion from prison of individuals with serious mental disorders. Given these important limitations, we do propose that the service estimates found may serve as a rough guideline to the minimum number of sessions a prison's psychiatric health services should be able to fulfil in order to serve the inmates psychiatric needs. The results rely on the specialist services' own estimates only. Future studies should take other important informants, including the inmates themselves, into consideration.
