Atrial fibrillation affects more than two million Americans, and it is more common as people age. About 15 percent of strokes occur in people with atrial fibrillation. The heart’s two upper chambers do not beat effectively in the condition, resulting in an irregular heart rhythm.
The research analyzed all of the available studies where people with atrial fibrillation were compared to people without atrial fibrillation and followed to determine who developed dementia over time.
A total of 15 studies were analyzed, with 46,637 participants with an average age of 72. The research found that stroke survivors with atrial fibrillation were 2.4 times more likely to develop dementia than stroke survivors who did not have the heart condition. About 25 percent of patients with stroke and atrial fibrillation were found to have developed dementia during follow-up.
“These results may help us identify potential treatments that could help delay or even prevent the onset of dementia,” said study author Phyo Kyaw Myint, MD, of the University of East Anglia in Norfolk, U.K. “Options could include more rigorous management of cardiovascular risk factors or of atrial fibrillation, particularly in stroke patients.”
Myint noted that the research on whether people who have atrial fibrillation but have not had a stroke have any greater risk of dementia was not conclusive.
The American Academy of Neurology, an association of more than 22,500 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 Alzheimer’s disease, stroke, migraine, multiple sclerosis, brain injury, Parkinson’s disease and epilepsy.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
