Exercise

Alzheimer's disease affects physical functioning as well as a person's mental ability. Patients show decreased mobility and an increased risk of falls and fractures. Due to decreased mobility, the patient is likely to experience decreased muscle mass leading to further loss of independence.

Exercise can improve general health and may alter the progression of Alzheimer's disease. Exercise programs that focus on improving endurance, strength, balance and flexibility may help increase the patient's mobility and independence despite the progression of the disease.

Exercise targets dementia by improving the health of neurons. Better neuron health means better communication within the brain and improvement of symptoms such as confusion, memory and comprehension. One reason that exercise may benefit those with Alzheimer's disease is stated in the "amyloid hypothesis". The "amyloid hypothesis" says that physical activity may decrease beta-amyloid levels (as recently found in mice), leading to fewer amyloid plaques and less disruption to neurons.

It is said that physically active people have greater 'cognitive reserve'. For the same deterioration in brain structure, physically active people show superior cognitive function . Similarly, education, occupation, and intelligence show protective effects on cognitive function. Exercise is associated with a myriad of benefits including improved cognitive functioning, mobility, independence, depression , and behavioural problems. If they are able, it is a good idea to encourage the person that you care for to become involved in an exercise program.
