Thedisease ischaracterized bya decrease off nerve cells and brain tissue.Forpatientswith Alzheimer's disease, memory lapses are typical, at the beginning of the disease states of anxiety and depression occur.The main cause isthe formation and deposition of β-amyloid and deficit of the neurotransmitter acetylcholine.
