Alzheimer’s disease (AD) is a progressive neurodegenerative disorder, primarily manifesting as a loss of memory in old aged people. In this disease the destruction of neurons in the cortex and limbic structures of the CNS occurs, particularly in basal forebrain, amygdala, hippocampus, cerebral cortex. These areas are associated with functions of higher learning, memory, reasoning, behaviour, identification, an emotional control in brain. Alzheimer's disease is a devastating disease whose recent increase in incidence rates has broad implications for rising health care costs. Clinically, patients initially present with short-term memory loss, subsequently followed by executive dysfunction, confusion, agitation, and behavioural disturbances. This review comprises aspects of the introduction, history, types, etiology, pathophysiologic mechanisms of neurological pathways of Alzheimer’s disease and the drug treatments and their target site.
