Both the presence and severity of neuropsychiatric symptoms, in particular mood/apathy alterations,had a significant impact on quality of life in subjects with PD.
Parkinson's disease (PD) is characterized by a wide spectrum of motor and non-motor features; the latter include a high prevalence of neuropsychiatric symptoms 1 . Depression and psychosis are among the most frequent neuropsychiatric symptoms in PD 2,3 . Depression and psychosis have been associated with poor health-related quality-of-life and disability 4,5,6 . Psychopharmacotherapy is currently considered the first-line of treatment for depression, as well as for psychosis in patients with PD. A recent meta-analysis on treatment for depression reported a moderate, but non-significant, pooled effect for antidepressants over placebo 7 , The rate of depression remission in PD is 37% to 44 8 . Regarding psychosis, response rates to antipsychotics have been reported to be complete in 33% and partial in another 33% of the cases 9,10 . In refractory cases, the use of electroconvulsive therapy (ECT) has been proved to have beneficial effects on both, neuropsychiatric symptoms and motor symptoms of patients with PD 11,12 . The majority of these studies are uncontrolled prospective or retrospective studies, or case reports. Moreover, the stigma surrounding ECT has may also account for a reduced use of it in the treatment of neuropsychiatric symptoms in subjects with PD.The objective of the present study is to analyze the effectiveness of electroconvulsive therapy for the management of depression and/or psychosis refractory to drug therapy in AbstrActObjective: To analyze the effectiveness of electroconvulsive therapy for the management of depression and/or psychosis refractory to drug therapy in patients with Parkinson disease. Method: A retrospective study was carried out including patients treated with electroconvulsive therapy during the period between 2002 and 2013. A review of the literature was performed. Results: A total of 27 patients were included. In regards to the neuropsychiatric diagnosis, 14 patients had major depression, 12 patients had both psychosis and depression, and only one patient had isolated psychosis. The mean number of electroconvulsive therapy sessions was 12 ± 2.8. After electroconvulsive therapy, all patients showed a statistically significant improvement in the Brief Psychiatric Rating scale (reduction of 52% points) and Hamilton Depression Rating Scale (reduction of 50% points) independent of the presence of psychosis, depression or both. Conclusion: Electroconvulsive therapy is effective for the treatment of refractory neuropsychiatric symptoms in Parkinson's disease.Keywords: Parkinson's disease, electroconvulsive therapy, psychosis, depression.rEsumo Objetivo: Analisar a eficácia da eletroconvulsoterapia para o tratamento da depressão e/ou psicoses refratária ao tratamento medicamentoso em pacientes com doença de Parkinson.

Background Pharmacological management of subjects with Parkinson's disease (PD) is complex. Regardless of drug selection, adherence is one of the main concerns. Nonadherence is associated with poor symptomatic control and low quality of life. In general, adherence to once‐a‐day formulations is thought to be better in comparison to 3‐times‐daily dosing. Methods A cross‐sectional study was carried out. Consecutive uninsured subjects diagnosed with PD were treated either with an immediate‐ or extended‐release dopamine agonist formulation. Clinical and demographic data were collected. Subjects were assessed using the International Parkinson and Movement Disorder Society UPDRS. Adherence was evaluated using the Morisky‐Green test (MGT). Results A total of 314 (175 males and 139 females) subjects with PD were included. In regard to treatment, 188 (59.9%) were on an immediate‐release dopamine agonist and 126 (40.1%) on an extended‐release dopamine agonist. According to the MGT, 21 (6.7%) subjects were classified as nonadherent, 273 (86.9%) with a low adherence, and only 20 (6.4%) were considered with high adherence. Dopamine agonist levodopa equivalent daily dose was higher in the extended‐release group (296.6 ± 112.4 vs. 231.3 ± 133.4; P = 0.011); also, these subjects had more years of formal education (12.3 ± 5.2 vs. 9.5 ± 5.2; P = 0.630). No difference in adherence levels was found (P = 0.802) between subjects treated with an immediate‐release dopamine agonist and those receiving an extended‐release formulation. Conclusions Overall adherence in subjects with PD is low. Use of an extended‐release over an immediate‐release dopamine agonist formulation in this study population is not associated with a better adherence.
Parkinson's disease (PD) is the second most common neurodegenerative disease. There are no clinical trials comparing all available pharmacological therapies for the treatment of early PD. The objective of this review is to indirectly analyze the efficacy of antiparkinson drugs currently available in Latin America. A systematic review was performed exploring only placebo-controlled randomized trials comparing antiparkinson monotherapy (levodopa, pramipexole, rasagiline, or selegiline) in patients with PD on Hoehn and Yahr stages I through III published from January 1994 to May 2014. The primary outcome was the mean change in the Unified PD Rating Scale (UPDRS) I, II and III. A mixed treatment comparison analysis (indirect comparisons) through a random-effects model was performed. Levodopa demonstrated the highest effects in terms of UPDRS score improvement both from baseline and when compared to other treatments. Levodopa showed a 60.1% probability of granting the greatest reduction in UPDRS I, II and III.
