Living with Tourette Syndrome
Living with Tourette Syndrome samer kareem 7,215 Views • 2 years ago

The cause for TS is unknown. Early research suggested that TS is an inherited condition (often, the person's near or distant relatives have had some form of transient or chronic tic disorder or associated symptoms). Recent studies point to a combination of environmental and genetic factors as a cause of the disorder. The specific genes involved in the development of TS are still being investigated. Studies suggest that TS has a neurological basis and results from an abnormality which affects the brain's metabolism of certain neurotransmitters (chemicals in the brain that regulate behavior.) Current research being funded by the Tourette Syndrome Association (TSA) will help provide more information about the causes and genetic factors of TS.

Tonsillectomy
Tonsillectomy samer kareem 25,685 Views • 2 years ago

Tonsillectomy (ton-sih-LEK-tuh-me) is the surgical removal of the tonsils, two oval-shaped pads of tissue at the back of the throat — one tonsil on each side. A tonsillectomy was once a common procedure to treat infection and inflammation of the tonsils (tonsillitis). Today, a tonsillectomy is usually performed for sleep-disordered breathing but may still be a treatment when tonsillitis occurs frequently or doesn't respond to other treatments. A tonsillectomy may also be necessary to treat breathing and other problems related to enlarged tonsils and to treat rare diseases of the tonsils.
