Alzheimer’s disease is a chronic (lifelong), progressive disease characterized by degeneration of the brain’s nervous tissue. It sets in gradually and typically presents in older people.
Alzheimer’s disease is the most common cause of dementia globally, accounting for 60 – 70% of all cases. According to the WHO, in 2019 there were 50 million people around the world with dementia, and the annual total for new cases was around 10 million.
The factors that can protect against developing Alzheimer’s disease include physical exercise, mental exercises, and breathing exercises that increase oxygen flow to the brain.
