精神科

Common symptoms

喃喃重复自语、喜讲秽语、抽动障碍、学习障碍、攻击行为、学习困难、模仿言语

The pathology of disease

Tic disorder is characterized by sudden, rapid, recurrent, non-rhythmic, stereotyped motor movements or vocalizations (tics), worsened by stress/excitement and temporarily suppressible. Subtypes: transient tic disorder (<1 year), chronic motor or vocal tic disorder, and Tourette syndrome (multiple motor + vocal tics, >1 year, onset <18). Tics usually improve by late adolescence. Treatment: education/reassurance, habit-reversal training, and medication (antipsychotics/alpha-agonists) only when impairing; manage comorbid ADHD/OCD.

Common Symptoms

Sudden rapid recurrent motor/vocal tics; worsened by stress; suppressible temporarily; onset childhood; may fluctuate

Causes and Pathogenesis
