It later affects areas in the cerebral cortex responsible for language, reasoning, and social behavior.
What are the two neurotransmitters involved in Alzheimer's disease?Alzheimer's disease is characterized by markedly reduced concentration of acetylcholine in hippocampus and neocortex, caused by degeneration of cholinergic neurons. Acetylcholine is essential in learning and memory.
Why does acetylcholine cause Alzheimer's?Two neurotransmitters seem to play a role in Alzheimer's Disease: acetylcholine and glutamate. Acetylcholine (ACh) activates muscles and helps with arousal, short-term memory, and learning. Individuals with AD have low levels of ACh.
What causes alzheimers disease?The causes probably include a combination of age-related changes in the brain, along with genetic, environmental, and lifestyle factors. The importance of any one of these factors in increasing or decreasing the risk of Alzheimer's disease may differ from person to person.
