Furthermore, studies have also proposed a relationship between oxidativestress and dysfunction in acetylcholinesterase (AChE) and Na+-K+-ATPase activity in many diseases [16]. AChE is responsible for the hydrolysis of the neurotransmitteracetylcholine (ACh) and this enzyme has been an important therapeutic target in ADsince this pathology was first associated with the loss of cholinergic neurons anddecrease in the level of ACh in the brain, leading to cognitive deficits [17,18].
