The cholinergic hypothesis (Fig. 1.3 C) was the first to be proposed; it summarizes the attenuation in the production of acetylcholine in cholinergic synapses in patients with AD [16]. Tohgi and coauthors demonstrated that there is a reduction of 73% in acetylcholine production comparing AD patients to healthy patients [68].
