Lucas Clark’s Family Page – Helping to Find a Cure

Lucas Clark’s Family Page – Helping to Find a Cure
2017 Update by Sidney Clark Dear Friends and Family, Lately we have been surrounded by so many devastating occurrences. Terrorist attacks, hurricanes, earthquakes, floods and fires have occurred one after another, and it seems like the world hasn’t had time to catch up. For a moment, I want you to put yourself in the head of one of the victims of these devastating occurrences. We are surrounded with external stressors that are beyond our control. You might feel overwhelmed, shocked, and left not knowing how to deal with the present situation. This is how my brother Lucas feels on a daily basis when triggered by seemingly insignificant things. If the food Lucas wants isn’t available, if his headphones are wrapped imperfectly around his phone, or if he is rushed anywhere, Lucas feels like his world is falling apart and immediately breaks down. Visiting a doctor for medical attention is traumatizingRead more

MicroRNA Mediated Astroglial GLT1 Dysregulation in Fragile X

MicroRNA Mediated Astroglial GLT1 Dysregulation in Fragile X

Almost all brain research focuses on neurons – nerve cells. However, the brain has many more glial cells which support, nourish, and protect the neurons. FRAXA Research Foundation awarded a 2017 grant $90,000 to support Dr. Yang’s studies of how changes in glial cells contribute to Fragile X syndrome. This grant is funded by a grant from the Pierce Family Fragile X Foundation.
