What is Alzheimer's Disease?

Alzheimer's disease is a seriously disabling neurodegenerative disease of the brain. Alzheimer's disease ...more »

  • Alzheimer's Disease: Dementia-causing brain disease mostly in seniors and the elderly.
  • Alzheimer's Disease: A degenerative disease of the BRAIN characterized by the insidious onset of DEMENTIA. Impairment of MEMORY, judgment, attention span, and problem solving skills are followed by severe APRAXIAS and a global loss of cognitive abilities. The condition primarily occurs after age 60, and is marked pathologically by severe cortical atrophy and the triad of SENILE PLAQUES; NEUROFIBRILLARY TANGLES; and NEUROPIL THREADS. (From Adams et al., Principles of Neurology, 6th ed, pp1049-57)

  • Alzheimer's Disease: a progressive form of presenile dementia that is similar to senile dementia except that it usually starts in the 40s or 50s; first symptoms are impaired memory which is followed by impaired thought and speech and finally complete helplessness.

How many people get Alzheimer's Disease?

Prevalance of Alzheimer's Disease: more than 4 million Americans (CDC); estimated 4 million people in the U.S (NHWIC)
Prevalance Rate of Alzheimer's Disease: approx 1 in 68 or 1.47% or 4 million people in USA [about data]

Who gets Alzheimer's Disease?

Patient Profile for Alzheimer's Disease: Over 40's; usually over age 65; 2-3% of age 65-74; about half over 85.

Profile for Alzheimer's Disease: AD usually begins after age 65, however, its onset may occur as early as age 40 (Source: excerpt from NINDS Alzheimer's Disease Information Page: NINDS)

Gender Profile for Alzheimer's Disease: AD is twice as common in women than in men, although former president Ronald Reagan is a well known disease sufferer. (Source: Genes and Disease by the National Center for Biotechnology)

Gender Profile for Alzheimer's Disease: Studies have shown that while the number of new cases of AD is similar in older adult women and men, the total number of existing cases is somewhat higher among women. 26 ,27 Possible explanations include that AD may progress more slowly in women than in men; that women with AD may survive longer than men with AD; and that men, in general, do not live as long as women and die of other causes before AD has a chance to develop. Research is being conducted to find ways to prevent the onset of AD and to slow its progression. (Source: excerpt from Women Hold Up Half the Sky: NIMH)

How serious is Alzheimer's Disease?

Prognosis of Alzheimer's Disease: Poor. Progressive deterioration from 5-20 years.
Complications of Alzheimer's Disease: see complications of Alzheimer's Disease
Prognosis of Alzheimer's Disease: AD is a progressive disease. The course of the disease varies from person to person. Some people have the disease only for the last 5 years of life, while others may have it for as many as 20 years. The most common cause of death in AD patients is infection. (Source: excerpt from NINDS Alzheimer's Disease Information Page: NINDS)
Average life years lost for Alzheimer's Disease: 6.8 years (SEER)1; 7.7 in North Carolina2.
Deaths for Alzheimer's Disease: 53,852 deaths in USA 2001 (CDC); 44,536 annual deaths (NVSR Sep 2001)
Cause of death rank for Alzheimer's Disease: 8th leading cause of death in 1999 and 2000 (CDC)
