A new study published in Nature Communications, a British scientific journal, has found that groups of genes in the human brain are involved in cognition, memory, spatial perception and reasoning. The research may lead to a breakthrough in the treatment of Alzheimer’s disease and cognitive impairment.
Researchers at the Centre for Cognitive Aging and Cognitive Epidemiology at the University of Edinburgh analyzed data from more than 300000 people aged 16 to 102 from Australia, Europe and North America. It was found that 148 DNA regions were related to human memory, reasoning ability, intelligence operation speed and spatial sense. Among them, 58 genes were previously unknown. The researchers believe the findings will help to understand why humans suffer from cognitive impairment that declines in cognitive ability.
Dr Gail Davies, who led the study, said: “this largest genetic study of cognitive function can identify many genetic differences in human genetic thinking skills. ”
In addition, the study found that the DNA region is associated with cardiovascular, mental health, lung cancer risk, and longevity. The team says they need to do much larger research to understand the overall picture and study the results carefully.
