What the latest research shows about the causes and detection of dementia: Testing for memory loss, contributing factors, and the growing burden of Alzheimer’s disease.

Appetite Hormone Linked to Alzheimer’s Disease

Having low levels of leptin, a hormone that regulates appetite, is linked to an increased risk of Alzheimer’s disease in people who have memory problems, according to a new report. The findings confirm earlier reports that leptin, which like other … Continue reading

Cancer Drug Shows Disappointing Results for Alzheimer’s

A cancer drug called bexarotene failed to live up to its early promise in treating the brain plaques of Alzheimer’s disease, though the drug did show some benefits in improving memory in animal studies. The mixed findings highlight the difficulty … Continue reading

Anesthesia Does Not Lead to Dementia, Study Finds

A new study provides reassurance to the millions of people who must undergo major surgery each year: general anesthesia does not appear to lead to an increased likelihood of developing Alzheimer’s disease or other forms of dementia. The findings, published … Continue reading

Poor Sleep May Be Early Sign of Alzheimer’s

People with Alzheimer’s disease often sleep poorly. Now, a new study shows that sleep problems may signal the early onset of Alzheimer’s disease. The findings, from researchers at Washington University School of Medicine in St. Louis, are consistent with earlier … Continue reading

Blood Pressure Drugs May Reduce Alzheimer’s Risk

Men and women who take drugs to keep high blood pressure in check may be somewhat protected against Alzheimer’s disease and other types of dementia, a new study found. And those who took a type of blood pressure drug called … Continue reading

Blacks and Whites Share Common Alzheimer’s Genes

One of the first broad studies of genetics in African Americans has found that blacks and whites of European ancestry share similar genes when it comes to the risk of developing Alzheimer’s disease, though there are slight differences. The research … Continue reading

Brain Changes Detected 20 Years Before Alzheimer’s Symptoms

Scientists increasingly recognize Alzheimer’s as a disease process that begins years before symptoms of dementia become evident. Now, new research has found changes in the brain and body up to 20 years before Alzheimer’s symptoms arise. The research, published in the journal … Continue reading

Newly Identified Gene Triples Alzheimer’s Risk

Researchers have discovered a new genetic defect that increases the risk of developing late-onset Alzheimer’s, by far the most common form of the disease, by threefold or more. The mutated gene is known to play a role in the immune … Continue reading

A Range of Diagnostic Tests for Alzheimer’s

Various tests for diagnosing Alzheimer’s disease have become available in recent years, although they remain imperfect diagnostic tools. Now researchers at Duke University report that using a combination of tests – two types of brain scans along with analysis of … Continue reading

Football Players at Increased Alzheimer’s Risk

Professional football players are at increased risk of dying from Alzheimer’s disease, a new study reports. The findings are consistent with earlier reports that concussions and other head injuries that damage the brain can raise the risk of Alzheimer’s and … Continue reading
