Grossman and Porth (2014), states that neurochemical changes in the brain are effected by Alzheimer’s disease and are the main cause of memory loss. Particularly, the level of choline acetyltransferase activity in the cortex and hippocampus is decreased. This is an enzyme that is required in order for acetylcholine (a memory neurotransmitter) to be synthesized, making the decrease in choline acetyltransferase enzymes quantitatively related to a large number of neuritic plaques (Grossman & Porth, 2014). According to the Alzheimer’s Association (n.d.b), the cortex shrivels up damaging the areas involved with thinking, planning, and remembering; the hippocampus (part of the cortex) also shrinks, which plays an imperative role in the formation of new memories.…
