Alzheimer’s disease affects most known biological pathways in the brain, researchers find

Nearly 6 million older adults have Alzheimer’s disease in the United States, a number expected to double by 2050. Already the sixth leading cause of death, Alzheimer’s disease is a complex neurodegenerative disease that causes memory loss, confusion, poor judgment, depression, delusions and agitation that robs people of their ability to live independently. Currently, the biological mechanisms underlying Alzheimer’s disease are poorly understood; as a result, there are few effective treatments and no cure for the disease.
