Memory Failing? You May Be at Higher Risk for Stroke

02.02.2010
People who experience memory loss or a decline in their thinking abilities may be at higher risk of stroke, regardless of whether they have been diagnosed with dementia, according to a new study published in the February 2, 2010, print issue of Neurology®, the medical journal of the American Academy of Neurology.

“Stroke is a leading cause of disability and death among older people, making early identification of people at high risk of stroke extremely important, so preventative measures can be taken,” said study author Bernice Wiberg, MD, with Uppsala University in Sweden.

For the study, 930 men in Sweden around the age of 70 without a history of stroke participated in three mental tests. The first test, called the Trail Making Test A, measures attention and visual-motor abilities. The second, the Trail Making Test B, measures the ability to execute and modify a plan. The third, the Mini Mental State Examination, is commonly used by doctors to measure cognitive decline.

During a 13-year period, 166 men developed a stroke or transient ischemic attack, or TIA. Brain infarction is the most common cause of stroke and happened to 105 patients. It causes tissue damage when the proper amount of blood does not reach the brain. Hemorrhage is another kind of stroke.

The study found that people who were among the bottom 25 percent of performers on the Trail Making Test B were three times more likely to have a stroke or a brain infarction compared to those who scored among the top 25 percent of performers on the test. The other two mental tests did not predict brain infarction or stroke.

“Our results support the idea that cognitive decline regardless of whether a person has dementia may predict risk of stroke,” said Wiberg. “The Trial Making Test B is a simple and cost-effective test that, with more research, could be used to identify those persons for whom stroke prevention measures should be considered.”

The study was supported by the Medical Faculty at Uppsala University, the Swedish Stroke Association, Swedish Research Council, the Swedish Heart Lung Foundation, the Geriatric Fund and the Uppsala County Association Against Heart and Lung Diseases.

The American Academy of Neurology, an association of more than 22,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as multiple sclerosis, restless legs syndrome, Alzheimer’s disease, narcolepsy and stroke.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
