Alzheimer’s disease is a progressive neurodegenerative disorder that can result in significant memory impairment. In saying that it is progressive, this means that it will progress overtime. It is mainly caused by the deposition of a protein that builds up both in and around brain cells. This also leads to the formation of plaques around the brain cells that hinder brain activity. In addition to memory loss, patients in the late stages of Alzheimer’s have speech challenges and difficulty registering their surroundings properly.
