Which aspect of Alzheimer's disease does acetylcholinesterase inhibitors aim to address?

Acetylcholinesterase inhibitors primarily aim to address the deficiency of acetylcholine (ACh) in patients with Alzheimer's disease by increasing the levels of this important neurotransmitter in the brain. In Alzheimer’s, there is a significant loss of cholinergic neurons, which impairs cognitive functions, particularly memory. By inhibiting acetylcholinesterase, the enzyme responsible for breaking down ACh, these drugs help to prolong the action of ACh in the synaptic cleft, thereby enhancing cholinergic transmission. This can lead to improvements in symptoms related to memory and cognitive functions, making it the best choice in relation to the primary goal of these medications.

Other aspects like improving memory retention or enhancing motor function are secondary outcomes that can occur as a result of increased ACh levels, but they are not the direct aim of the drug. Upholding neurogenic development is less relevant in the context of current treatments, as acetylcholinesterase inhibitors are not primarily designed to promote the growth of new neurons but rather to counteract the decline associated with existing cholinergic pathways. Thus, the focus remains on increasing ACh levels to support cognitive functions impaired in Alzheimer's disease.
