Abstract
Alzheimer’s Disease (AD) is a neurodegenerative disease. The disease itself
is progressive and full recovery from it isn’t achievable yet. There are several
hypotheses asserted (Cholinergic hypothesis, Amyloid hypothesis etc.) to explain the
mechanisms behind the disease. Also, many targets have been identified for possible
therapeutics and from these targets, numerous drug candidates have been evaluated in
clinical trials. Unfortunately, most of these trials failed due to the enigmatic nature of
this disease. Currently, there are 7103 targets associated with Alzheimer's disease listed
in the Open Targets platform where 1240 of them are enzyme-related. In this chapter,
enzymatic targets of the AD have been reviewed, and those claimed to have disease modifying effects were selected and presented according to their clinical significance.
