Dementia & Alzheimer’s Disease and Exercise

08 Feb Dementia & Alzheimer’s Disease and Exercise

Alzheimer’s disease (AD) is a neurodegenerative disease in which brain cells are progressively destroyed causing a loss of cognitive, memory and physical function and a progressive decline in quality of life. AD mostly affects older people and is the leading cause of dementia.

 

Approximately 332 000 Australians had dementia in 2014, and this number is expected to increase to 550 000 people by 2030, and 891 000 people by 2050. The biggest reason for the increase in AD incidence is Australia’s ageing population, caused by greater life expectancy and the post-war increase in birth rates (the ‘baby boomer’ generation).

 

 

WHY EXERCISE IS IMPORTANT

 

 

The risk factors for Alzheimer’s disease — which are largely associated with reduced physical activity — suggest that exercise can help to prevent or delay Alzheimer’s disease.

 

Exercise can also be used as a ‘medicine’ for managing established AD by: slowing the progression of AD in people with mild to moderate cognitive impairment improving physical and mental function slowing or reversing the muscle wasting often associated with advanced disease improving mood and depression in patients with existing disease and lessening behavioural problems in people with advanced disease.

 

People who are physically active have a lower risk of developing AD than those who are inactive. Furthermore, starting and maintaining an exercise program is associated with reduced levels of beta amyloid — a protein that forms plaques on the brain and is currently thought to be the main cause of AD.

 

Exercise can benefit people who already show signs of AD by improving their quality of life, slowing down the disease progression, and improving physical function and health.

 

THINGS TO REMEMBER:

One on one exercise supervision is advised over group exercise due to need for close supervision, instruction of exercises and counting of repetitions.

  • For outside activities, encourage the wearing of a medical alert bracelet or pendant.
  • Use weight machines rather than dumbbells or barbells that can be dropped.

 

 

TYPES OF EXERCISE RECOMMENDED:

Exercise Right recommends 30 minutes of activity per day, for at least five days a week. This can be broken up into shorter sessions throughout the day, with each session lasting a minimum of 10 minutes.

 

The goals of exercise to prevent or manage AD are to maintain or increase muscle mass and strength; decrease risk factors for cardiovascular disease and metabolic syndrome; increase testosterone levels; and provide a socially engaging and interactive environment.

 

Exercise (particularly resistance or weight training) also increases testosterone levels, which can help to protect brain cells and preserve cognitive function.

 

People with dementia can also benefit from a regular programme of seated exercise sessions at home under supervision or with a supervised group at a local class. These exercises are aimed at building or maintaining muscle strength and balance, and are less strenuous than exercises in a standing position. They can be part of a developing programme, with the number of repetitions of each exercise increased over time.

 

Some examples of seated exercises include:

  • marching
  • turning the upper body from side to side
  • raising the heels and toes
  • raising the arms towards the ceiling
  • raising the opposite arm and leg
  • bending the legs
  • clapping under the legs
  • bicycling the legs
  • making circles with the arms
  • practising moving from sitting to standing.
