Chemical Signals Go Awry in Fragile X Syndrome
Mouse study shows drugs that target the miscommunication may help
MONDAY, Jan. 14 (HealthDay News) — New information about how brain cells are affected in Fragile X syndrome — the most common cause of inherited mental retardation — has been uncovered.
In the study, researchers at the University of Texas Southwestern Medical Center at Dallas examined mice to see how Fragile X syndrome affects communication between cells in the hippocampus, a part of the brain involved in learning and memory. The team found that two different chemical signals go awry in Fragile X syndrome. This suggests that drugs that interact with these chemical signals may offer a treatment.
