Alzheimer's disease is one of the forms of dementia (and the commonest). It is irreversible, progressive and, as of now, incurable.


In Alzheimer's disease, the development of plaques or beta-amyloid protein and tangles of tau protein are thought to be responsible for the progressive loss of memory.

While such plaques and tangles are common in aging people, in those with Alzheimer's disease, they develop much faster and, in a few cases, can even start much earlier.

Initially, the symptoms of Alzheimer's are short-term memory loss, but as the disease progresses, the person loses even cognitive and communication ability. This is thought to be caused both by the breakdown of communication between nerve cells by the plaques and tangles, and by the death of nerve cells as the disease progresses.

As the brain gets increasingly affected, the symptoms include a state of confusion, disorientation, inability to remember faces and names, mood swings, paranoia, suspicion, and a slow breakdown of physical functions such as eating, drinking, walking, and talking.

Alzheimer's disease is a disease which leads to problems in which old or aged persons loose their memory power and forget different issues.


Alzheimer's disease leads to Dimentia which leads to memory loss of aged persons. This reduces the brain functioning of older people.
This occurs due to lesser application of brain tissues and is incurable.
