Many medications ease the constellation of symptoms that define Parkinson's disease, but the only treatment that slows the progression of the neurological movement disorder can't be purchased at a pharmacy. It's high-intensity, cardiovascular exercise, like boxing, and it's changing lives.

The chemical cross-communication between the guts and other organs that occurs when a person metabolizes nutrients begins before we open our mouths, when we see or smell food. The answer to why some people develop obesity, diabetes, and other metabolic disorders, and why some people respond so well to medicines like Ozempic, might lie in those signals. UT Health San Antonio endocrinologist Dr. Marzieh Salehi is studying that communication in patients with spinal cord injury.

Jannine Cody, PhD, founded and leads the Chromosome 18 Clinical Research Center, which has revolutionized the understanding of and care for disorders caused by alterations in chromosome 18 in humans. However, Cody began this mission as a mom with a baby with a chromosome 18 disorder who needed care.

A team of San Antonio researchers is training artificial intelligence models to help improve the materials used to make things like cavity fillings and dental sealants, which currently tend to be either unattractive or not as durable as they could be. This could dramatically decrease the time it takes to get better products into dentists' offices and clients' mouths.

CTE can rob a person of their memories and ability to make decisions and plans. It can also cause a person to become a threat to themselves and, sometimes, others.
