BACKGROUND: The majority of people living with Parkinson's disease will develop impairments in cognition. These impairments are associated with a reduced quality of life.
OBJECTIVE: The Cochrane Review aimed to investigate whether cognitive training improves cognition in people with Parkinson's disease and mild cognitive impairments or dementia.
METHODS: A Cochrane Review by Orgeta et al. was summarized with comments.
RESULTS: The review included seven studies with a total of 225 participants. There was no evidence for improvements in global cognition when cognitive training was compared to control conditions. Observed improvements in attention and verbal memory measures after cognitive training could not be confirmed in a subsequent sensitivity analysis. There was no evidence for benefits in other cognitive domains or quality of life measures. The certainty of the evidence was low for all comparisons.
CONCLUSIONS: The effectiveness of cognitive training for people with Parkinson's disease and cognitive impairments remains inconclusive. There is a pressing need for adequately powered trials with higher methodological quality.
