Serotonin signaling is central to depression and anxiety disorders, but could also play important roles in the pathogenesis of several age-related disorders, including Alzheimer’s disease. Alzheimer's disease (AD) is the most common form of dementia affecting 35 million individuals worldwide and this is expected to increase to 115 million by 2050.Therefore, modulation of defined serotonin receptors by specific ligands represents a promising tool for treatments for neurodegenerative diseases like AD. Serotonin neurons located in the raphe nucleus of the hindbrain have crucial roles in regulating brain functions and brain development where it regulates neurite outgrowth, synaptogenesis and cell survival. This paper provides a review the synthesis of serotonin and an overview of the involvement of the serotonergic system in AD Keywords: Serotonin; nerve cell survival; alzheimer's disease
