What're the risk factors for Alzheimer's disease?
The risk for Alzheimer's disease increases with each decade of adult life. People with a family history of Alzheimer's have a greater risk, implying that a genetic factor is involved. A clear inherited pattern of Alzheimer's disease exists in less than 10% of cases. Some involve a mutation of the gene for the protein APP, found on chromosome 21. Nearly all people with Down's syndrome (trisomy 21) who live into their 40s develop the disease. Others involve a defect on chromosome 14. The gene for the protein Apo E, found on chromosome 19, is a risk factor that may be involved in modifying the age of onset.
Untreated chronic high blood pressure (hypertension) has been identified as a risk factor for loss of mental function in older people. Treatment reduces the risk. Adults who have had head injuries are three times more likely to develop Alzheimer's disease.
It is thought that gender plays a role because several studies suggest that women are afflicted with Alzheimer's disease more often than men. However, the evidence is inconsistent and some studies report that the disease is more prevalent in men. Therefore, more research is needed to obtain conclusive evidence regarding prevalence in gender.
The risk of developing Alzheimer's disease is as much as four times higher for African Americans as for Caucasians. A study published in the Journal of the American Medical Association recently compared the risk of Alzheimer's disease among African Americans and Africans from Nigeria, and found that the risk was nearly twice as high for African Americans as for the Nigerians studied. The risk for Latinos is twice that of whites. People of Asian and Native American descent are at lower risk. It is unclear whether these differences in risk are due to genetic heritage, health, or social or cultural differences between ethnic groups. What is clear, however, is that Alzheimer's disease affects all ethnic groups worldwide.
Lower Education and Economic Groups. A number of studies have reported either a higher risk for Alzheimer's disease in people with less education or a lower risk for Alzheimer's disease in those who remain mentally active. Some experts speculate that learning itself may stimulate more neurons to grow and thus create a larger reserve in the brain so that it takes longer for brain cells to be destroyed.
The risk of Alzheimer's disease or dementia was twice as high for those with a history of moderate head injury (loss of consciousness or amnesia for 30 minutes to 24 hours) and four times as high for those with a history of severe head injury (loss of consciousness for more than 24 hours). It is not yet known if such injuries directly cause Alzheimer's or simply accelerate the disease in people who are already susceptible to it.
There is a significant overlap between depression and dementia in the elderly. Some evidence suggests that there may even be common genetic factors in people who have both early depression and Alzheimer's disease. Being depressed may increase your risk of developing Alzheimer's disease, even if the depression was earlier in adulthood. In the elderly, the symptoms of depression can mimic the symptoms of Alzheimer's disease. It is important that depression be ruled out when obtaining a diagnosis for an elderly person displaying symptoms of dementia.
Slow, infectious viruses cause a number of other degenerative neurologic diseases, such as kuru and Creutzfeldt-Jakob disease. Although no specific virus has been linked to Alzheimer's, some researchers theorize that people with a genetic susceptibility to Alzheimer's may be vulnerable to the actions of certain viruses, particularly under circumstances when the immune system may be weakened.
Some laboratory studies have reported excessive amounts of metal ions such as zinc, copper in Alzheimer's disease brain. Such ions may possibly change the chemical architecture of normal beta amyloid, making it more harmful. A mildly acidic environment appears to be important in the process that binds these metals to beta amyloid. Experts observe that such conditions (acidic environment and higher levels of zinc and copper) commonly occur as part of the inflammatory response to local injury.

What's alcohol-related dementia? - Alcohol related dementia is a form of dementia related to the excessive drinking of alcohol. Alcohol abuse can lead to several forms of dementia.
What's frontal lobe dementia? - Frontal lobe dementia is a set of degenerative diseases producing many of the same symptoms as vascular dementia. The frontal lobe governs people's mood and behaviour.
What's senile dementia? - Senile dementia is the mental deterioration (loss of intellectual ability) that is associated with old age. Senile dementia is often used when referring to Alzheimer's disease.
What's early onset dementia? - Early onset dementia is a term that covers a range of diseases affecting memory and thinking in people under the age of 65.
What's AIDS related dementia? - HIV associated dementia (HAD) is comprised of a spectrum of conditions from the mild HIV-1 motor cognitive-motor disorder to severe and debilitating AIDS dementia.
