Clinical Manifestations.

Background: It is believed that delayed perseveration on a semantic verbal fluency (SVF) test may occur due to impaired working memory (WM). However, the relation between perseveration and switching, and the self-generated interference one has to overcome when switching back to a previously visited subcategory has not been explored. In this study we wanted to see: 1) if perseverative errors in SVF test require switching and subsequent switch back to a previously explored subcategory; (2) if this trend would parallel cognitive decline.

Effects of Meditation on Structural Changes of the Brain in Patients With Mild Cognitive Impairment or Alzheimer's Disease Dementia.

Previous cross-sectional studies reported positive effects of meditation on the brain areas related to attention and executive function in the healthy elderly population. Effects of long-term regular meditation in persons with mild cognitive impairment (MCI) and Alzheimer's disease dementia (AD) have rarely been studied. In this study, we explored changes in cortical thickness and gray matter volume in meditation-naïve persons with MCI or mild AD after long-term meditation intervention.
