History & Effects of Alzheimer's Disease

Alzheimer's disease is a brain disorder that was first described in 1906 by a physician named Alois Alzheimer, according to alz.org. Alzheimer's disease kills brain cells, causing cognitive problems and memory loss. It is a form of dementia that has no cure.

  1. Origin of Name

    • In 1910, Emil Kraepelin, a German psychiatrist, coined the phrase "Alzheimer's disease" after Alois Alzheimer.

    First Alzheimer's Case

    • In 1901, August D. showed signs of language and cognitive deficits. Alzheimer and Kraepelin studied August D. until she died in 1906. Her brain was later examined for further research.

    Plaques

    • Plaques damage nerve cells in the brain. They consist of a protein called beta-amyloid. Beta-amyloid is broken down in normal brains but hardens and multiplies in Alzheimer's patients.

    Tangles

    • Tangles are fibers found inside brain cells. The protein found in these fibers collapses and becomes abnormal.

    Memory Loss

    • Memory loss is the hallmark of Alzheimer's disease. Forgetting names, important dates and recent information is common.
