Study ties obesity-related gene to weaker memory

• http://medicalxpress.com, by Randy Dotinga
Researchers found the link between genes and memory in whites but not in blacks. The research "could be useful in identifying people who may need more help with declining cognition," said John Speakman, a professor at the Institute of Biological and Environmental Sciences at the University of Aberdeen in Scotland, who is familiar with the findings. Although some people believe obesity is purely a failure of individual will, scientists think genetic makeup has a lot to do with the propensity to gain extra pounds. Studies of twins and families suggest that genes account for about 65 percent of variance in body weight, Speakman said. The new study focuses on four genetic traits related to a gene that's thought to play a role in obesity. Researchers looked for signs of the traits among nearly 8,400 white and 2,100 black people aged 45 to 64.
They found signs of a link between problems being able to remember words and two of the genetic traits. The connection held up even after the researchers adjusted their results so they wouldn't be thrown off by factors like large or small numbers of people who were of certain ages, genders, levels of obesity and education levels.
