Detailed explanation-1: -By the final stages of Alzheimer’s, this process-called brain atrophy-is widespread, causing significant loss of brain volume.
Detailed explanation-2: -Alzheimer’s disease damages cells that produce and use acetylcholine. Certain medications can increase levels of acetylcholine. They do this by blocking the action of enzymes that break down the neurotransmitter.
Detailed explanation-3: -Individuals with AD have low levels of ACh. Some research suggests that plaques may be one of the reasons for low levels of ACh because they increase the activity of a chemical called acetylcholinesterase, which is involved in breaking down ACh.
Detailed explanation-4: -Cholinergic neurons are most damaged in AD brain. Decline of acetylcholine (ACh) concentration in AD brain is also known.
Detailed explanation-5: -Alzheimer’s tissue has many fewer nerve cells and synapses than a healthy brain. Plaques, abnormal clusters of protein fragments, build up between nerve cells. Dead and dying nerve cells contain tangles, which are made up of twisted strands of another protein.
