Alzheimer’s Disease

Alzheimer’s disease (also called Alzheimer disease, or Alzheimer’s) is the most common form of dementia. This incurable, degenerative, and terminal disease is diagnosed in people over 65 years of age, although the less-prevalent early-onset Alzheimer’s can occur much earlier. In 2006, there were 26.6 million sufferers worldwide. Alzheimer’s is predicted to affect 1 in 85 people globally by 2050. Although the course of Alzheimer’s disease is unique for every individual, there are many common symptoms. In the early stages, the most commonly recognised symptom is inability to acquire new memories, such as difficulty in recalling recently observed facts. When Alzheimer’s is suspected, the diagnosis is usually confirmed with behavioural assessments and cognitive tests, often followed by a brain scan if available.
