[['tic', 'has cause', 'tic disorder'], ['tic', 'description', 'repetitive, nonrhythmic motor movement or vocalization involving discrete muscle groups']]
A <entity_2> is a sudden, <entity_0>. The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published in May 2013, reclassified Tourette's and <entity_2> disorders as motor disorders listed in the neurodevelopmental disorder category, removed the word "stereotyped" from the definition of <entity_2> to better distinguish between stereotypies and tics, replaced transient <entity_1> with provisional <entity_1>, removed the criterion that tics must occur nearly every day, and removed the criterion that previously had excluded long <entity_2>-free periods (months) from counting towards the year needed to diagnose Tourette's or Persistent (Chronic) <entity_2> disorders.
