Brain exercises may help thinking in Parkinson's disease, but the studies are few.
HelpedThe short version
In four studies, the same brain exercises helped planning and control skills more than other groups did.

The review
Who took part
480 people with Parkinson's disease took part in 14 trials, published from 2006 to 2014. Their average age was 66, and only two trials included people with memory or thinking problems.
What they did
Eight trials gave the same brain exercises to everyone, and three set them up for each person. Three used repeated magnetic pulses. Trials ranged from 8 minutes to 45 hours in total.
What happened
The same exercises helped planning and control, attention and memory more than other groups did. Set-up exercises did not clearly help those skills, and magnetic pulses did not help planning and control. The summary says set-up exercises may help too, but results were unclear, and small studies may be missing.

How solid is this?
- Unclear how groups were picked
- Summary claims more than the results show
- Mixes trials with other kinds of study
- Signs that small negative studies went unpublished
