Article Synopsis
  • The study examines how Parkinson's disease (PD) medication affects cognitive functioning, psychiatric symptoms, impulsivity, and quality of life in patients with advanced PD who are preparing for deep brain stimulation surgery.
  • It compares effects of low versus high dosages of levodopa-equivalent dosage (LED) and the presence or absence of dopamine agonists on neuropsychological performance.
  • Results indicate that lower LED correlates with better performance in impulsivity tests and that dopamine agonists can negatively impact verbal learning tasks and increase psychiatric symptoms, suggesting the need for careful consideration before surgery.

Background: The hippocampal formation represents a key region in the pathophysiology of schizophrenia. Aerobic exercise poses a promising add-on treatment to potentially counteract structural impairments of the hippocampal formation and associated symptomatic burden. However, current evidence regarding exercise effects on the hippocampal formation in schizophrenia is largely heterogeneous.

Introduction: To date, concrete recommendations for physical activity in psychiatric treatments are limited. Thus, we evaluated knowledge, barriers and beliefs associated with exercise prescription of mental health professionals (MHP) to people with mental illnesses. We aimed to identify patients' barriers to exercise participation and to work out options addressing these barriers.

Introduction: Previous studies described various adaptive neuroplastic brain changes associated with physical activity (PA). EEG studies focused mostly on effects during or shortly after short bouts of exercise. This is the first study to investigate the capability of EEG to display PA-induced long-lasting plasticity in runners compared to a sedentary control group.

Exercise interventions are nowadays considered as effective add-on treatments in people with schizophrenia but are usually associated with high dropout rates. Therefore, the present study investigated potential predictors of adherence from a large multicenter study, encompassing two types of exercise training, conducted over a 6-month period with individuals with schizophrenia. First, we examined the role of multiple participants' characteristics, including levels of functioning, symptom severity, cognitive performance, quality of life, and physical fitness.
