High Blood Pressure Linked to Memory Problems in Middle Age

High blood pressure is linked to memory problems in people over 45, according to research published in the August 25, 2009, print issue of Neurology®, the medical journal of the American Academy of Neurology.

The study found that people with high diastolic blood pressure, which is the bottom number of a blood pressure reading, were more likely to have cognitive impairment, or problems with their memory and thinking skills, than people with normal diastolic readings.

For every 10 point increase in the reading, the odds of a person having cognitive problems was seven percent higher. The results were valid after adjusting for other factors that could affect cognitive abilities, such as age, smoking status, exercise level, education, diabetes or high cholesterol.

The study involved nearly 20,000 people age 45 and older across the country who participated in the Reasons for Geographic And Racial Differences in Stroke (REGARDS) Study and had never had a stroke or mini-stroke. A total of 1,505 of the participants, or 7.6 percent, had cognitive problems, and 9,844, or 49.6 percent, were taking medication for high blood pressure.

High blood pressure is defined as a reading equal to or higher than 140/90 or taking medication for high blood pressure.

“It’s possible that by preventing or treating high blood pressure, we could potentially prevent cognitive impairment, which can be a precursor to dementia,” said study author Georgios Tsivgoulis, MD, of the University of Alabama at Birmingham and a member of the American Academy of Neurology.

Research has shown that high diastolic blood pressure leads to weakening of small arteries in the brain, which can result in the development of small areas of brain damage.

Tsivgoulis said more research is needed to confirm the relationship between high blood pressure and cognitive impairment.

The study was supported by the National Institute of Neurological Disorders and Stroke (NINDS).

“The REGARDS study is one of the largest population-based studies of risk factors for stroke. These latest data suggest that higher blood pressure may be a risk factor for cognitive decline, but further studies will be necessary to understand the cause-effect relationship,” said Walter J. Koroshetz, MD, deputy director of NINDS and Fellow of the American Academy of Neurology. “The National Institutes of Health is now organizing a large clinical trial to evaluate whether aggressive blood pressure lowering can decrease a number of important health outcomes including cognitive decline.”

The American Academy of Neurology, an association of more than 21,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic 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.

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
