Alzheimer's Disease and Exercise
What is Alzheimer's Disease
Alzheimer’s disease (AD) is the most common form of dementia that accompanies the aging process and involves oxidative damage to the brain. This degenerative brain disease results in loss of ability to:
- Cope with every day activities,
- Mental deterioration,
- Memory disturbances and

risk of developing AD if another family member has AD.
Prevention for Alzheimer's Disease
Physical Activity/Exercise and Diet
Regular exercise through mid-life reduces risk of AD by 60%. Vascular diseases such as hypertension, coronary heart disease, diabetes and strokes have been found to have an association with AD. Regular exercise has been shown to decrease the risk of vascular diseases and therefore can help delay the symptoms of AD by.
- Directly counteracting vascular oxidative stress seen in AD patients and
- Indirectly by reducing the vascular burden – a critical factor for AD onset.
There is no physical activity/exercise specifically for AD. General physical activity guidelines would be appropriate to reduce vascular risks associated with AD. Additional research suggests that the risk of cognitive decline decreased twofold in patients who completed greater than 1 hour of exercise daily at a high to moderate intensity level is associated with a decrease risk of AD.

Throughout the course of AD patients can develop malnutrition, increased rate of falls, fractures, muscle loss, behavioural disturbances and depression. This can result in a decreased quality of life, independence and, high rate hospitalisation, disability and death.
Benefits of Physical Activity/Exercise
Regular exercise in AD patients can significantly improve their ability to complete every day activities such as cleaning, cooking, hanging washing out (etc). To improve quality of life, ability to complete every day activities, decrease the risk of diseases (i.e. hypertension, diabetes) an AD exercise program should include:
- Aerobic/endurance activities,
- Neuromuscular coordination/balance and
- Strength of the major muscle groups.
Research has suggested moderate exercise program of one hour conducted twice a week significantly slows the progressive deterioration by up to a 1/3.
