Alzheimer’s disease is an irreversible, progressive brain disorder that
slowly destroys memory and thinking skills and, eventually, the ability to
carry out the simplest tasks. In most people with the disease—those
with the late-onset type—symptoms first appear in their mid-60s. Early-
onset Alzheimer’s occurs between a person’s 30s and mid-60s and is
very rare. Alzheimer’s disease is the most common cause
of dementia among older adults. The disease is named after Dr. Alois
Alzheimer.
Proteins build up in the brain to form
structures called plaque and tangles. This
leads to the loss of connections between
nerve cells and eventually causing the
death of nerve cells and loss of brain
tissue
