Alzheimers risks

Using this test early could indicate the likelihood of someone having or developing the disease. Two categories of genes influence whether a person develops a disease: risk genes and deterministic genes. People can have more than one type of dementia. Alzheimers risks of a mouse study, published in Nature, suggested in that It may one day be possible to restore memories for people with early Alzheimer's.

Most genetic mechanisms of Alzheimer's among families remain largely unexplained, and the genetic factors are likely complex. These include: Lack of exercise Smoking or exposure to secondhand smoke High blood pressure High cholesterol Poorly controlled type 2 diabetes These factors can all be modified.

It involves plaques and tangles forming in the brain. Risk factors Unavoidable risk factors for developing the condition include : aging a family history of Alzheimer's carrying certain genes Modifiable factors that may help prevent Alzheimer's include: getting regular exercise managing the risk of cardiovascular disease, diabetesobesitysmoking, and high blood pressure following a varied and healthful diet participating in lifelong learning and cognitive training Some studies suggest that staying mentally and socially engaged may possibly reduce the risk of Alzheimer's.

Heart-head connection: Some of the strongest evidence links brain health to heart health. In the future, emerging biological tests may make it possible to assess for biomarkers in people who may be at risk of Alzheimer's.

Causes and risk factors Like all types of dementia, Alzheimer's is caused by brain cell death.

Sex There appears to be little difference in risk between men and women, but, overall, there are more women with the disease because they generally live longer than men. Poor sleep patterns Research has shown that poor sleep patterns, such as difficulty falling asleep or staying asleep, are associated with an increased risk of Alzheimer's disease.

These effects can increase vulnerability to additional health problems such as: Inhaling food or liquid into the lungs aspiration Pneumonia and other infections. But these mutations account for less than 1 percent of people with Alzheimer's disease.
