The main symptoms of Tourette’s syndrome are motor and sound tics, often accompanied by psychiatric disorders. These are almost always accompanied by psychiatric manifestations. tics occur intensely and repeatedly, but they can be temporarily controlled by voluntary effort, although this is usually limited to short periods. In children, the types of tics vary over time: some may disappear to make room for others.
Diagnosis of Tourette’s syndrome
According to the DSM-5 criteria, the disease begins before the age of 18, there are motor and vocal tics that appear regularly for more than a year and are not due to drug use or other neurological disease.
Disease severity is achieved by an objective measurement of tics using the Yale Global Tic Severity Scale (YGTSS).
The diagnosis of Tourette’s syndrome is said to be differential because it is sometimes necessary to eliminate other pathologies. In clinically complex cases, neurophysiological methods may be particularly useful in differentiating tics from other abnormal movements that may be similar, such as dystonia (muscle twisting movements) or myoclonus (muscle twitching).
