Alzheimer’s disease

What are the causes?

Alzheimer’s is a physical disease which attacks brain cells (where we store memory), brain nerves and transmitters (which carry instructions around the brain). Production of numerous chemical messengers, including acetylcholine and glutamate, are disrupted as nerve ends are attacked and cells die. The brain shrinks as gaps develop in the temporal lobe and hippo-campus, important for receiving and storing new information. The ability to remember, speak, think and make decisions is disrupted. After death, tangles and plaques made from protein fragments, dying cells and nerve ends are discovered in the brain. This confirms the diagnosis.
