Alzheimer's disease is a neurological condition that gradually impairs an individual's ability to remember things, think rationally, and perform cognitive tasks. Alois Alzheimer, a German doctor, was the first to identify the disorder in 1907; one in nine persons who are 65 years of age or older are estimated to have the condition.

It is a chronic condition that progresses and worsens over time eventually making the patient incapable of carrying out basic daily tasks. The destruction and damage of neurons (brain nerve cells) in the brain are what cause the weakening of memory and cognitive abilities.

Alzheimer’s disease is also considered to be influenced by a variety of other intricate alterations in the brain. Memory-related regions of the brain(hippocampus entorhinal cortex), initially suffer damage.Subsequently, it impacts parts of the cerebral cortex that are involved in language, thinking, and socialising.Other parts of the brain eventually suffer harm as well.

Dementia generally refers to a state of cognitive decline that is severe enough to limit one’s daily life activities. At least two-thirds of dementia cases in people over 65 years old are brought on by AD, the most prevalent form of dementia. Someone with AD can exhibit dementia-like symptoms, which is known as Alzheimer’s dementia. But not all dementia patients have AD…read more on NOPR
