Are There Early Signs of Alzheimer’s Disease to Watch For?

Alzheimer’s is a progressive brain disorder that happens in phases, slowly destroying a person’s memory, cognitive functions, and eventually many physical abilities as well. The condition happens in five different stages, starting with what’s known as preclinical Alzheimer’s disease. This is when a person isn’t showing any signs of the condition, but their brain is undergoing changes that will eventually cause symptoms.

During this time, protein deposits in the brain form abnormal clumps that interrupt the way brain cells communicate, the Mayo Clinic explains. The brain also begins to create tangled bundles of the fibers necessary for transporting materials essential for proper brain function, like nutrients. These changes mean that neurons that used to be healthy stop functioning, lose connections with other neurons, and die, according to the National Institute on Aging (NIA).
