Physical activity can help to improve dementia

A study conducted in London in a total of 70 participants over 65 years consisting of 30 individuals with dementia and 40 healthy controls. It showed Physical fitness is associated with higher global cognition in individuals with dementia, independent of their levels of past exercise and illness duration. A possible explanation proposed for this could that physical activity stimulates blood circulation in frontostriatal circuits, improving executive function in older adults with dementia. 

What is dementia?

Dementia is a syndrome, usually of a chronic or progressive nature .There is deterioration in cognitive function (i.e. the ability to process thought) beyond what might be expected from normal ageing. It affects memory, thinking, orientation, comprehension, calculation, learning capacity, language, and judgment. Consciousness is not affected in dementia. In India more that 4 million people have some form of dementia. The global societal economic cost of dementia is enormous (US $818 bn) which is  equivalent in magnitude to the GDP of countries like Indonesia, The Netherlands, and Turkey, the 16th to 18th largest economies in the world.

 Risk factors for dementia:

  • Physical inactivity,
  • obesity,
  • unhealthy diets,
  • tobacco use and harmful use of alcohol,
  • diabetes, and midlife hypertension.
  • Additional potentially modifiable risk factors include depression, low educational attainment, social isolation, and cognitive inactivity.
