A new study from Houston Methodist suggests that obesity may affect the brain through harmful fat molecules that travel from body tissues into the brain. The team wanted to understand why obesity has been linked with a higher risk of Alzheimer’s disease in many earlier studies. They found that correcting the imbalance improved brain function and thinking ability in Alzheimer’s disease models. The researchers stressed that the findings do not mean everyone with obesity will develop Alzheimer’s disease.
