Dementia May Affect Motor Skills

There is accumulating evidence that dementia has a long preclinical phase that may begin years or even decades before a clinical diagnosis.1 In addition, data indicating the preclinical signs of dementia and declines in memory and other cognitive skills also include motor skill difficulties.

It's difficult to tease out regular age-related changes in coordination and balance from those motor skills that put people at increased risk for dementia. Measures of preclinical impairments include changes in gait and walking speed, loss of muscle mass and strength, as well as reduced manual agility and balance.

Once Dementia becomes part of the picture, friends and family members become increasingly aware of the changes in their loved one's memory and organizational skills. They may also notice their loved one has difficulty dressing or walking without assistance. Like the worsening cognition we associate with Dementia, losses in stamina and coordination also reflect more widespread brain damage.

Research shows that physical exercise plays a vital role in helping to protect, maintain, and improve the health and well-being of people in either the preclinical or the clinical stages of dementia. As is true for everyone, physical exercises must be safe, enjoyable, and give a sense of accomplishment. However, before embarking on new or increased physical activity, you must get approval from your loved one's doctor.

A physical therapist (PT) is often an excellent place to start. They can devise an exercise plan to improve stamina, flexibility, balance and exercises to prevent falls. You can find information about local physical therapists on the American Physical Therapy webpage: Your loved one's doctor, nurse, or medical social worker are other good sources of information.

Exercise also includes walking, dancing, gardening, and (ugh) housework. All are inexpensive, do not require specialized equipment, and come with the satisfaction of having done something worthwhile. As an added benefit, all of these, and similar activities, are sources of social and cognitive stimulation.

Exercise also includes activities that improve small or fine-muscle motor skills. The ability to button a shirt, open a cereal box, or use eating utensils helps people living with Dementia maintain their independence for as long as possible. An occupational therapist (OT) can suggest helpful exercises and adaptive equipment that can make it possible to live at home for as long as possible. Go to The American Occupational Therapy Association webpage to learn more about occupational therapy and the many ways occupational therapy can help people who have dementia:

Small muscle exercises include pastimes such as craft projects, scrapbooking, baking, working with clay, painting, and drawing. These simple, inexpensive small muscle activities encourage socialization and maintain or improve cognition. An added benefit, and perhaps the most important one, is making things to share with others creates mementos of a life together and affirms the whole person.
