World Alzheimer’s Day
September 21 is World Alzheimer’s Day. Alzheimer’s disease is one of the most widespread forms of dementia among senior people. The disease affects the regions of the brain, responsible for memory, thinking, and speech. The most common early symptom of Alzheimer’s disease is loss of short-term memory (or difficulty in remembering recent events).
The number of people suffering from Alzheimer’s disease increases every year. By 2050 their number will grow four times. In the USA Alzheimer’s disease is the sixth widespread cause of death among people older than 18 years and the fifth among people older than 65.
Observation of World Alzheimer’s Day raises public awareness of this disease and helps recognize it in early stages. Annual events are coordinated by Alzheimer’s Disease International and the World Health Organization. Purple was chosen to be the color of the day. Wear purple on purpose to express your support and awareness.
