A team of Florida State University College of Medicine researchers has found a link between a specific protein in the brain and increased vulnerability to neurodegeneration for individuals with temporal lobe epilepsy (TLE).
Tumors are made up of many types of cells, both cancerous and benign. The specific complexity of the cells inside brain tumors has been a trademark of the disease, one that makes treatment extremely difficult. While scientists have long known about the variety of cells within a brain tumor, the ways these tumors grow has relied on the understanding that the cells are static, unmoving and relatively fixed.
An important new study of diverse communities is looking at how brain changes, genetics and other factors contribute to dementia and Alzheimer’s disease. The results could affect millions. Among people 65 and older, about 1 in 9 has Alzheimer’s disease.
