Alzheimer's disease is an age-related, irreversible brain disorder that destroys memory and other important mental functions. It is the most common cause of dementia in older people. Dementia is a loss of thinking, remembering, and reasoning skills that interferes with a person’s daily life and activities.

Alzheimer's disease begins slowly and first involves parts of the brain that control thinking, memory and language. A related problem called mild cognitive impairment (MCI), causes more memory problems than normal for people of the same age.

Alzheimer’s disease Facts:

According to the Centres for Disease Control and Prevention, Alzheimer's disease is the sixth leading cause of death in the United States.

The National Institutes of Health funding for HIV/AIDS research in the United States is 23 times more that for Alzheimer's disease research.

Mortality rates for Alzheimer’s disease are increasing, unlike in the case of heart disease and cancer death rates, which are continuing to decline.

Alzheimer’s affects more than five million Americans and is expected to increase exponentially in the next few decades.

Older age is the major risk factor for Alzheimer’s disease; the disease rate doubles every five years after age of 65 years.

Every 68 seconds, one person in America develops Alzheimer's disease.

Nearly 44 million people are believed to be suffering from Alzheimer's disease or other dementias, which could exceed 135 million by 2050 if there is no breakthrough in the future.

Causes of Alzheimer's include a combination of genetic, environmental, and lifestyle factors.

The common symptoms of Alzheimer’s disease include memory loss and confusion, which can proceed to behavioural and other changes.

For the treatment of Alzheimer's disease, the U.S Food and Drug Administration has approved four medications.

Donepezil, rivastigmine or galantamine are used to treat mild-to-moderate Alzheimer's. Memantine and donepezil are used to treat moderate-to-severe Alzheimer's disease.
