New Genetic Clues to Alzheimer’s Cause Found

Scientists continue to look for the cause or causes of Alzheimer’s disease in genetics, lifestyle, and injuries to the head. Alzheimer’s is the most common type of dementia, and generally occurs in older patients. In persons over age 65 one in eight will develop the disease, and in those over age 85 almost half have Alzheimer’s. Alzheimer’s cannot be diagnosed with 100% accuracy except by autopsy. Autopsy has shown that the brain cells of all people who die at an advanced age have some plagues and tangles in their brains.

Co-morbidities Can Be Deadly for Alzheimer’s

A new study finds that people with Alzheimer’s disease who also have diabetes or high blood pressure may die sooner than people without such disorders.

Researchers studied 323 people who had no memory problems when first tested but later developed dementia. Memory tests and physical exams were then given every 18 months.

The study found that after an Alzheimer’s diagnosis was made, people with diabetes were twice as likely to die sooner than those without diabetes who had Alzheimer’s disease. People with Alzheimer’s disease who had high blood pressure were two-and-a-half times more like to die sooner than those with normal blood pressure.

Different Ethnic Response to Antidepressants

In a new study, a team of researchers discover Spanish-speaking Hispanics take longer to respond to medication for depression and are less likely to go into remission than English-speaking Hispanics.

Scientist from the Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center (LA BioMed) report their findings in November’s Psychiatric Services journal.

Using data from the nation’s largest real-world clinical study of depression, the researchers found the Spanish-speaking participants in the study were older and were more likely to be women than the English speakers.
