The study involved 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.
“Studies show that the average lifespan of a person diagnosed with Alzheimer’s can be anywhere from three to nine years. For that person and their caregiver, every minute counts. Here we have two controllable factors that may drastically affect how long that person can survive,” said study author Yaakov Stern, PhD, professor at the Taub Institute for Research on Alzheimer’s Disease and the Aging Brain and director of the Cognitive Neuroscience Division of Gertrude H. Sergievsky Center at Columbia University Medical Center in New York. Stern is also a member of the American Academy of Neurology.
The study also looked at how race could affect how long a person lives with Alzheimer’s disease. It found Hispanic people lived for eight years after diagnosis, about four years longer than non-Hispanic white people did. African-Americans lived an average of five years, longer than non-Hispanic whites but not as long as Hispanic people. However, after adjusting for gender and other factors, the results were no longer significant.
“Though these findings were not significant, they are intriguing and warrant further research as to whether race affects survival time in people with Alzheimer’s disease,” said Stern.
The study was supported by the National Institute on Aging.
The American Academy of Neurology, an association of more than 21,000 neurologists and neuroscience professionals, is dedicated to improving patient care through education and research. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as epilepsy, dystonia, migraine, Huntington’s disease, and dementia.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
