ABSTRACT The study was aimed to examine the prevalence of depression in patients with Parkinson's disease (PD) and identify its features. A total of 131 out-patients, diagnosed as having idiopathic PD in accordance with the United Kingdom Parkinson's Disease Society Brain Bank criteria, were interviewed with questionnaire and evaluated by Mini-Mental State Examination (MMSE), Unified Parkinson's Disease Rating Scale (UPDRS), Hohen &Yahr staging (H&Y staging) and Hamilton Rating Scale for Depression (HRSD). Patients were divided into three groups in terms of HRSD score: depression group, sub-threshold depression group and non-depression group. The clinical variables and symptom profiles were obtained and compared among the three groups. The results showed that 27 patients (20.6%) fell into the depression group, 71 (54.2%) into the sub-threshold depression group, and 33 (25.2%) into the non-depression group. There were no differences in age, gender or tremor score among the groups (P>0.05). Significant differences were found in duration of PD, UPDRS score, rigidity score and H&Y stage between the sub-threshold depression group (or the depression group) and the non-depression group (P<0.05). Moreover, the clinical variables in the subthreshold depression group had the trend of increasing with the severity of PD and their values were similar to those in the depression group. Anhedonia, feeling of incapability, sleep disturbance, gastrointestinal symptoms and depressive moods were most common in the depression group. And these symptoms also were more common in the other two groups. It is concluded that depression and sub-threshold depression are common in PD and share similar clinical features. Furthermore, subthreshold depression might be the prodrome of depression and may develop into depression as the condition progresses.

    Article: Postural control in bipolar disorder: increased sway area and decreased dynamical complexity.
    [show abstract] [hide abstract]
    ABSTRACT: Structural, neurochemical, and functional abnormalities have been identified in the brains of individuals with bipolar disorder, including in key brain structures implicated in postural control, i.e. the cerebellum, brainstem, and basal ganglia. Given these findings, we tested the hypothesis that postural control deficits are present in individuals with bipolar disorder. Sixteen participants with bipolar disorder (BD) and 16 age-matched non-psychiatric healthy controls were asked to stand as still as possible on a force platform for 2 minutes under 4 conditions: (1) eyes open-open base; (2) eyes closed-open base; (3) eyes open-closed base; and (4) eyes closed-closed base. Postural sway data were submitted to conventional quantitative analyses of the magnitude of sway area using the center of pressure measurement. In addition, data were submitted to detrended fluctuation analysis, a nonlinear dynamical systems analytic technique that measures complexity of a time-series, on both the anterior-posterior and medio-lateral directions. The bipolar disorder group had increased sway area, indicative of reduced postural control. Decreased complexity in the medio-lateral direction was also observed for the bipolar disorder group, suggesting both a reduction in dynamic range available to them for postural control, and that their postural corrections were primarily dominated by longer time-scales. On both of these measures, significant interactions between diagnostic group and visual condition were also observed, suggesting that the BD participants were impaired in their ability to make corrections to their sway pattern when no visual information was available. Greater sway magnitude and reduced complexity suggest that individuals with bipolar disorder have deficits in sensorimotor integration and a reduced range of timescales available on which to make postural corrections.
