The neurotransmitter acetylcholine —related to neuronal transmission and body movement— may experience a decrease in its production leading to Alzheimer's, according to the cholinergic hypothesis.

Many therapies and treatments at present are based on the use of drugs to correct the acetylcholine deficit.

Regarding other options:

Dopamine: alteration or deficit is related to Parkinson's disease.
Gamma aminobutyric acid (GABA): deficiency is not common and is related to a type of congenital and infantile neuropathy.
Serotonin: deficit of this neurotransmitter can lead to depression and psychological disorders.
