Alzheimer's disease facts

  • Over 26.6 million people worldwide are believed to suffer with Alzheimer’s disease (AD).
  • This incurable, degenerative, and terminal disease was first described by German psychiatrist and neuropathologist Alois Alzheimer in 1906 and was named after him.
  • As the disease advances, symptoms include confusion, irritability and aggression, mood swings, language breakdown, long-term memory loss, and the general withdrawal of the sufferer as their senses decline.
  • When Alzheimer's disease is suspected, the diagnosis is usually confirmed with behavioural assessments and cognitive tests, often followed by a brain scan if available.
  • A biopsy of the brain after death is the only definite diagnosis of AD.
  • Alzheimer's is predicted to affect 1 in 85 people globally by 2050.
  • The risk of developing Alzheimer’s grows with old-age, doubling every 5 years beyond the age of 65.
  • The mean life expectancy following diagnosis of AD is approximately 7 years.
  • AD is more common in women due to the fact women live longer than men.
  • Fewer than 3% of individuals live more than fourteen years after diagnosis.
  • Rare hereditary forms of Alzheimer’s disease can strike people in their 30s and 40s.
  • Because Alzheimer's disease cannot be cured and is degenerative, management of patients is essential.
  • AD is the most common form of Dementia, affecting 75 percent of all cases.
  • In developed countries, Alzheimer's disease is one of the most costly diseases to society.
