Review question

In older people, does visual art therapy improve cognitive (thinking) ability?

Background

Decline in cognitive ability is common in older adults. Risk or progression of cognitive decline may be reduced by exposing the brain to challenging mental activities. Visual art therapy involves several mental activities (creativity, planning, decision making, cognitive control, abstract thinking, and verbal expression) that may stimulate the brain, but it is not known whether it can help improve thinking and prevent cognitive decline.

How the review was done

The researchers did a systematic review of studies available up to September 2019. They found 10 randomized controlled trials and 1 nonrandomized study that included a total of 831 people.

Key features of the studies were

• patients were 60 years of age or older, and the average age was 71 years;
• 63% were women;
• people had normal cognition, cognitive decline without a diagnosis, mild cognitive impairment, Alzheimer disease, or any type of dementia;
• visual art therapy included drawing, painting ceramic plates and tiles, coloring abstract patterns, painting, or visual art cognitive evaluation and analysis;
• visual art therapy was done in supervised group-based activities that allowed interaction;
• visual art therapy sessions were 35 minutes to 2 hours long, one to three times per week for 4 to 40 weeks; and
• visual art therapy was compared with recreational activities, theatre art, singing/music, cognitive stimulation, or no activity.

What the researchers found

Compared with control, visual art therapy:

• improved global cognition (overall thinking) by a small amount in people with mild cognitive impairment;
• improved working memory (the ability to remember information for a short time) by a moderate amount;
• reduced depressive symptoms by a small amount; and
• reduced anxiety by a small amount.

Conclusion

In older people with mild cognitive decline, visual art therapy improves cognitive ability by a small amount.
