A To Z Disease Directory / 02 Aug 2019



Alzheimer's disease is a type of progressive disorder that causes brain cells to degenerate and die which extirpate memory and other functions of the brain. It most commonly causes dementia which gives rise to continuous decline in thinking, behavioral and social skills that distort the ability to function and think independently. As the symptoms gets worse, it becomes difficult for people to remember the recent events and to recognize people they know. Alzheimer's disease has no cure at present, but treatments for reducing the symptoms are available. Although the available Alzheimer's treatments cannot stop it from progressing, but they can temporarily slow down the worsening of dementia symptoms and improve quality of life.


  • The exact cause is still unclear but this is mostly caused by a genetic transformation, or permanent change in one or more specific genes. Disease can inherit through parent genetic transformation to affect the upcoming generation.
  • A neurodegenerative disorder which causes continuous brain cell death over a period of time to lead to Alzheimer’s disease.


  • Memory loss that distorts daily life – Affected people tend to forget communications frequently, important dates or events, ask for the same information repeatedly, and rely upon memory aids like reminder notes or electronic devices.
  • Challenges in thinking and finding the solution - Difficulty in developing and following a plan to work with numbers, keeping track of monthly bills, concentration and time management.

  1. Regular exercise and quality sleep
  2. Healthy diet
    • Minimal use of sugar and refined carbohydrates.
    • Avoid Trans fats - The fats can cause inflammation and produce free radicals which are hard on the brain.
