Regular exercise helps memory in dementia

Regular walking and doing strength exercises improves memory and thinking skills in elderly people with dementia. This is according to research from the University Medical Center in Groningen.

Walking and strength exercises not only have a positive impact on physical fitness in elderly people with dementia. They also improve memory and sharp thinking skills. This improves the skill with which everyday tasks are performed which ultimately contributes to a better quality of life. 

Research

109 people aged 75 years and older living in a nursing home and suffering from dementia were followed for nine weeks. Two exercise programs were evaluated: walking for 30 minutes four times a week or walking for 30 minutes twice a week and doing 30 minutes of strength exercises twice a week.

The combination of walking and strength exercises was most successful. Stamina, leg strength and balance improved, but memory, recognition of people and concentration also showed positive development. This ensured that participants had less difficulty, for example, putting on a coat or spreading a sandwich. 

However, when there is no more exercise or strength training, the effect quickly disappears. The researchers therefore urge that both walking and strength training be made a structural part of the care of older people with dementia.
