Background and purpose: Depressed mood is a common psychiatric problem associated with Parkinson's disease (PD), and studies have suggested a benefit of rasagiline treatment. Methods: ACCORDO (see the) was a 12-week, double-blind, placebo-controlled trial to evaluate the effects of rasagiline 1 mg/day on depressive symptoms and cognition in non-demented PD patients with depressive symptoms. The primary efficacy variable was the change from baseline to week 12 in depressive symptoms measured by the Beck Depression Inventory (BDI-IA) total score. Secondary outcomes included change from baseline to week 12 in cognitive function as assessed by a comprehensive neuropsychological battery; Parkinson's disease quality of life questionnaire (PDQ-39) scores; Apathy Scale scores; and Unified Parkinson's Disease Rating Scale (UPDRS) subscores. Results: One hundred and twenty-three patients were randomized. At week 12 there was no significant difference between groups for the reduction in total BDI-IA score (primary efficacy variable). However, analysis at week 4 did show a significant difference in favour of rasagiline (marginal means difference ± SE: rasagiline -5.46 ± 0.73 vs. placebo -3.22 ± 0.67; P = 0.026). There were no significant differences between groups on any cognitive test. Rasagiline significantly improved UPDRS Parts I (P = 0.03) and II (P = 0.003) scores versus placebo at week 12. Post hoc analyses showed the statistical superiority of rasagiline versus placebo in the UPDRS Part I depression item (P = 0.04) and PDQ-39 mobility (P = 0.007) and cognition domains (P = 0.026). Conclusions: Treatment with rasagiline did not have significant effects versus placebo on depressive symptoms or cognition in PD patients with moderate depressive symptoms. Although limited by lack of correction for multiple comparisons, post hoc analyses signalled some improvement in patient-rated cognitive and depression outcomes. © 2015 The Authors.

Background. Episodic memory and semantic abilities deteriorate early in Alzheimer disease (AD). Since the cognitive system includes interconnected and reciprocally influenced neuronal networks, the authors hypothesized that stimulation of lexical-semantic abilities may benefit semantically structured episodic memory. Objective. To investigate the effects of lexical-semantic stimulation (LSS) on verbal communication and episodic memory in early AD. Methods. Forty AD participants were randomized to LSS or unstructured cognitive stimulation (UCS) as control condition. Treatments lasted 3 months, 2 sections a week. The primary outcome measures were the Mini-Mental State Examination (MMSE), Boston Naming Test (BNT), Verbal Naming Test (VNT), Phonemic and Semantic Fluency, Story Recall, and Rey Auditory Verbal Learning (RAVL). Secondary outcome measures were neuropsychological tests assessing cognitive functions not stimulated by the intervention, such as attention, executive functions, and visual-spatial abilities, and the instrumental activities of daily living scale. A 6-month follow-up assessment was administered to the LSS group. Results. LSS treatment yielded significant improvements of the MMSE, BNT, VNT, Brief Story Recall, and RAVL delayed recall mean scores. Among secondary outcome measures, only working memory and the speed of a task assessing executive functions (Stroop test) improved after LSS. Unstructured cognitive stimulation intervention did not improve any cognitive domain. Six months after LSS discontinuation, the MMSE mean score remains significantly higher than the baseline value. Conclusion. LSS treatment may improve episodic memory in AD patients and may be regarded as a clinical option to counteract the cognitive decline typical of the disease. © 2012 The Author(s).
