Alzheimer's disease is a form of dementia which is caused by low levels of neurotransmitter acetycholine in the cortex of the brain associated with the destruction of neurons.
According to research, enzyme cholinesterase can effectively raise the acetylcholine level in the brain but it cannot reverse the destruction of neurons.
Alzheimer's disease is irreversible and can be inherited.
