Alzheimer's disease is a neuro-degenerative disease that causes the decline of cognitive functions, reducing work and social relationship capacities, in fact, Alzheimer's is characterized by regular and important fluctuations in the ability to remember things, with a few days better than others. Over time, it also interferes with the person's behavior and personality, causing consequences such as memory loss.
