What is Alzheimer’s disease (AD)?

The Rotary Club of St. Maarten launched its Alzheimer’s awareness campaign last week Wednesday. As part of this campaign articles and useful information will be published. The source of the information in this article titled "What Is Alzheimer’s disease" is the US National Institute of Health – National Institute on Aging.

Alzheimer’s disease (AD) is an irreversible, progressive brain disease that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks of daily living. In most people with AD, symptoms first appear after age 60.

AD is the most common cause of dementia among older people, but it is not a normal part of aging. Dementia refers to a decline in cognitive function that interferes with daily life and activities. AD starts in a region of the brain that affects recent memory,then gradually spreads to other parts of the brain. Although treatment can slow the progression of AD and help manage its symptoms in some people, currently there is no cure for this devastating disease.

AD is named after Dr. Alois Alzheimer, a German doctor. In 1906, Dr. Alzheimer described changes in the brain tissue of a woman who had died of an unusual mental illness. He found abnormal clumps (now called amyloid plaques) and tangled bundles of fibers (now called neurofibrillary tangles).

Today, these plaques and tangles in the brain are considered hallmarks of AD. The third main feature of AD is the gradual loss of connections between nerve cells (neurons) in the brain. This loss leads to diminished cell function and cell death.

We don’t know what starts the AD process, but we do know that damage to the brain begins as many as 10 to 20 years before any obvious signs of forgetfulness appear.

As nerve cells die throughout the brain, affected regions begin to shrink. By the final stage of AD, damage is widespread, and brain tissue has shrunk significantly.

More information will become available during the three month Rotary Alzheimer’s Awareness campaign. For more information please contact the St. Maarten Alzheimer’s Foundation on HOTLINE 9220 or al**********@gm***.com.

The Rotary Club of St. Maarten will continue with articles and provide more insight into the disease, the symptoms and provide tips for patients and caregivers.

To support the campaign please contact any member of the Rotary Club or the St. Maarten Alzheimer’s Foundation.
