Alzheimer's Disease

Nearly 10 percent of men over age 70 suffer from Alzheimer’s disease, a form of dementia where parts of the brain that control thought, memory, and language are impaired and can seriously affect a person’s ability to carry out daily activities. It is the most common form of dementia, with more than 5 million sufferers living in the United States.

Researchers at the Mayo Clinic found men are more susceptible to mild cognitive declines than women. The study of senior citizens, between ages 70 and 89, found men were 1.5 times as like to experience mild cognitive impairment (MCI) than women. Researchers found their test group in Olmstead County, Minn.

MCI is a condition where people having thinking and memory problems more severe than age-related changes. It’s thought to be a gateway to Alzheimer’s and other types of dementia.

Not all patients with cognitive impairment develop Alzheimer’s.

The exact causes of Alzheimer’s disease is not known, but research shows many factors can contribute to the development of the disease. Age is the most important known risk factor for Alzheimer’s disease – the number of people with the disease doubles every 5 years beyond age 65. Family history is another risk factor; genetics may play a role in developing Alzheimer’s disease.

A study published in the journal Neurology, found that free testosterone levels – testosterone not bound to any other substance in the blood – may be lower in men with the disease.
