Shedding excess body weight can promote your health. As reported by a study performed by Umea University in Sweden, it can have a good influence on brain in older age as well. The researchers discovered that after six months of healthy eating, the participants demonstrated a substantial improvement in their memory skills. This convinced the scientists that they’re able to reverse the obesity-related degradation in memory function.
The research involved 20 older, overweight women. They went through a sequence of cognitive exams to find out exactly how great was their episodic memory. The monitoring of brain activity on this team was recorded using magnetic resonance imaging (MRIs).
During the cognitive assessments, the subjects were asked to pair faces and names that were shown on the display. Matching the face using the first letter of their names was a protocol the researchers utilized in memory recalling task. As they were doing so, the scientists analyzed their brain process on MRIs. This technique is referred to as “encoding”.
The increased brain activity was observed in regions vital for recognition and the matching of faces as the subjects who had reduced body weight performed memory encoding exercises. The researchers in addition discovered that regions responsible for impaired episodic memories was observed with reduced brain activity. This suggested that the brain was more efficient in retrieving info.
According to the Swedish lead scientist, whenever a women loses weight, it changes the brain activity. This indicates that the brain becomes more active as its keeps new memories. This negates the requirements of additional brain resources to recall stored information.
In the past, one research indicated that impaired episodic memory was prevalent among overweight individuals. At Northwestern Medicine in the United States back in 2010, scientists learned that memory loss corresponded with the woman’s weight. It appeared that the memory loss was also related to the body frame of the women – pear or apple-shaped. If it turns out the woman had more weight around her hips, her memory loss was more evident than women with love handles around their waists.
