Scientists found that diminished levels of a special class of neurotransmitters called hypocretins which are produced by neurons in the hypothalamus have been implicated in a sleep disorder called. Neurotransmitters based therapy in Alzheimers disease such as cholinesterase inhibitors NMDA receptor inhibitors GABAergic modulators serotonin receptor modulators histaminergic modulators and adenosine receptor modulators. The most common early symptom is difficulty in remembering recent events.

However despite correlation between cholinergic defect and intellectual impairment. Two that have been found to be involved in schizophrenia symptoms are dopamine and glutamate. Cholinergic neurotransmission has been implicated in a number of disease states.

The best-known neurotransmitters responsible for such fast but short-lived excitatory action are acetylcholine norepinephrine and epinephrine while GABA is the major inhibitory neurotransmitter. A serotonin B dopamine C acetylcholine D GABA.

Postsynaptic receiving neuron is less likely to have an action potential. Acetylcholine ACh a neurotransmitter essential for processing memory and learning is decreased in both concentration and function in patients with Alzheimers disease. One particular reason is that impairment of the cholinergic system often manifests in patients with dementia.
