Physical activity and neuropsychiatric symptoms of Parkinson disease

Neuropsychiatric symptoms of Parkinson disease (PD) such as fatigue, depression, and apathy are common and detract from quality of life. There is little published on the impact of physical activity on the neuropsychiatric symptoms of PD. A convenience sample of 45 patients with PD (mean age = 66.1 years; 33% female) completed questionnaires on physical activity, neuropsychiatric symptoms, and specific exercise preferences. Covarying for age and gender, higher levels of physical activity were associated with significantly less fatigue, as well as a trend for less apathy and depression and greater positive affect. Exercise preferences included moderate intensity (73%), at home (56%), in the morning (73%), scheduled (69%), options for varied activities (73%), and preference for both structured/supervised (50%), and unsupervised/self-paced (50%) programs. Preferred activities included the use of aerobic exercise equipment, resistance training, and yoga. Developing and tailoring exercise programs that incorporate specific preferences may result in more effective interventions for patients with PD. © The Author(s) 2012

Design and rationale for a randomized controlled trial testing the efficacy of aerobic exercise for patients with obsessive-compulsive disorder

Background: Over the last two decades very few advances have been made in the development of new treatments for obsessive-compulsive disorder (OCD). While patients with OCD improve with available treatments (pharmacotherapy and/or cognitive-behavioral therapy), moderate levels of OCD symptoms often persist even with adequate doses and durations of these treatments. Building on the growing body of evidence for the efficacy of exercise in the treatment of other psychiatric disorders, interventions to increase aerobic exercise in patients with OCD represent a potentially useful yet relatively unexplored strategy in OCD. Methods/design: One hundred and two (102) patients with clinically significant OCD symptoms despite current engagement in recommended treatments (pharmacotherapy and/or CBT) will be randomly assigned to receive either a 12-week moderate-intensity aerobic exercise (AE) intervention or a health education control (HEC) intervention. Follow-up interviews will be conducted at the end of treatment and at 3-, 6- and 12-months post-intervention. They will assess OCD severity, nonspecific anxiety, depression, quality of life, cardiorespiratory fitness and cognition (executive function). Discussion: If efficacy is established, patients with OCD who have clinically significant residual symptoms despite current pharmacotherapy or CBT would gain a valuable and practical treatment augmentation option.

A pilot randomized controlled trial of aerobic exercise as an adjunct to OCD treatment.

ObjectiveThe purpose of the current study was to conduct a randomized controlled trial testing the efficacy of aerobic exercise for decreasing OCD symptom severity, other mental health outcomes, and increasing exercise behaviors and cardiorespiratory fitness among individuals with OCD.MethodFifty-six patients (64% female; mean age=38.8years) with OCD and a Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) score of 16 or greater despite engaging in OCD treatment were randomized to 12-weeks of supervised plus home-based moderate-intensity aerobic exercise (AE; n=28) or to 12-weeks of health education sessions (HE; n=28).ResultsRandom intercepts mixed models examined differences between conditions at post-treatment. Though no difference between conditions on outcomes was observed, both AE and HE showed significant reduction in OCD symptom severity, depression and anxiety at post-treatment. Relative to HE, significant increases were noted in amount of exercise and cardiorespiratory fitness for those in the AE condition. At post-treatment, 30.4% of the AE condition (7 of 23) were treatment-responders (using the commonly accepted measure of 35% symptom reduction from baseline). In the HE condition, 7.7% of the sample (2 of 26) met this criterion at post-treatment.ConclusionThe results of this preliminary study suggest that exercise and health-focused interventions may be beneficial adjuncts to existing OCD treatment. Future studies with larger samples are needed to more definitively answer questions the efficacy of AE for reducing OCD symptoms and improving related clinical outcomes
