Tic disorder (TD) is a complex chronic neuropsychiatric disorder that begins in childhood and adolescence and is characterized by involuntary sudden, rapid, repetitive, non-rhythmic, stereotyped single or multi-site muscle movements or vocal tics. It can be divided into transient tic disorder, chronic motor or vocal tic disorder, and combined vocal and multiple motor tic disorder. Possible etiologies of tic disorders include genetic factors, neuromodulation disorders and functional defects of the dopamine system. 1, the clinical manifestations of tic disorder? The clinical manifestations of transient tic disorder in tic disorders are: sudden, repetitive, and stereotyped one or more motor tics and vocal tics. However, most present as simple motor tics, and a few present as simple vocal tics. The most common motor tics are twitches of the face, head and neck, and arms, and vocal tics are also common. Chronic motor or occurrence tic disorders manifest primarily as one or more motor tics or vocal tics, but motor and vocal tics do not coexist. The most common twitches are motor twitches, especially of the face, head and neck, and limbs. Tourette’s syndrome (TS) is the most representative of tic disorders, with the most complex and severe clinical presentation, and the most difficult to diagnose and treat. The onset of symptoms in patients usually appears in the first 5 to 8 years of adolescence. Initially, the symptoms are similar to those of transient motor tic disorder, with lighter and shorter duration twitches, mainly of the face, head and upper limbs. Over time, tic symptoms persist and become more varied and widespread, usually progressing from the upper part of the body to the trunk and legs. 2. What is the treatment for Tourette’s syndrome? The treatment used includes medication and psychotherapy. Medications can directly improve tic symptoms, and commonly used medications include aripiprazole, haloperidol, thiopride, colistin, etc. Psychotherapy, on the other hand, is an important part of the comprehensive treatment and is the main tool to prevent relapse and reduce complications of the disease. Psychological transference and cognitive-behavioral therapy (self-monitoring methods, relaxation exercises, biofeedback, etc.) are commonly used. A good prognosis for tic disorders is based on a complete and systematic psychological treatment and family and social support.
