Acetylcholine is a neurotransmitter that plays a crucial role in memory and cognitive function. The "cholinergic hypothesis" of Alzheimer's disease and related forms of senility (now more commonly referred to as dementia) posits that a decline in acetylcholine levels in the brain is a major contributor to cognitive decline. This hypothesis is scientifically validated by numerous studies showing reduced acetylcholine activity in the brains of patients with Alzheimer's disease and other dementias.

While acetylcholine itself is not directly administered as a treatment (due to its rapid breakdown and inability to cross the blood-brain barrier), several medications used to treat symptoms of senility—such as donepezil, rivastigmine, and galantamine—are acetylcholinesterase inhibitors. These drugs work by inhibiting the breakdown of acetylcholine, thereby increasing its availability in the brain and partially compensating for the cholinergic deficit. Clinical trials have demonstrated modest benefits in cognition, behavior, and activities of daily living among patients with mild to moderate Alzheimer’s disease and some other dementias.

Thus, while acetylcholine itself is not used as a direct therapy, the scientific foundation for supporting cholinergic neurotransmission in senility is well-established, and several approved pharmacological treatments are based on this principle. However, the effects are generally modest and do not halt disease progression, which is reflected in the evidence rating.
