Alzheimer's disease is a progressive brain disorder that affects memory, thinking, and emotions. It is the most common form of dementia, and currently has no cure. However, treatments to reduce the symptoms are being developed.

• 00:00:00 Alzheimer's disease is the most common form of dementia, affecting over 40 million people in the world. German psychiatrist Alois Alzheimer described the symptoms for the first time in 1901, when he noticed that a patient in a hospital had problems. These problems included difficulty sleeping, problems with memory, drastic changes in mood, and a growing confusion. When the patient died, Alzheimer was able to perform an autopsy and find that the symptoms were due to abnormalities in the brain's structure. Under a microscope, he discovered differences in the brain's tissue, specifically in the form of senile plaques and neurofibrillary tangles. These plaques and tangles form together and destroy the brain's structure, typically appearing first in areas responsible for memory. Alzheimer's disease progresses in a sequential manner, first attacking the front part of the brain responsible for thinking and emotions, and then moving on to the emotional area at the back of the brain. Eventually, the disease affects areas in the brain that control breathing and the heartbeat, leading to death. There is currently no cure for Alzheimer's, but treatments such as reducing acetylcholine production and developing a vaccine to attack beta-amiloides plaques before they form deposits are being pursued. Alzheimer's disease was first identified
