Stereotypic movement disorder is often misdiagnosed as tics or Tourette syndrome (TS). [6] [7] Unlike the tics of TS, which tend to appear around age six or seven, repetitive movements typically start before age three, [1] [8] are more bilateral than tics, and consist of intense patterns of movement for longer runs than tics. Tics are less ...

Tic disorders are more commonly diagnosed in males than females. [3] At least one in five children experience some form of tic disorder, most frequently between the ages of seven and twelve. [9] [10] Tourette syndrome is the more severe expression of a spectrum of tic disorders, which are thought to be due to the same genetic vulnerability ...
Motor disorders are disorders of the nervous system that cause abnormal and involuntary movements. They can result from damage to the motor system. [1]Motor disorders are defined in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) – published in 2013 to replace the fourth text revision – as a new sub-category of neurodevelopmental disorders.
Punding is a term that was coined originally to describe complex prolonged, purposeless, and stereotyped behavior in chronic amphetamine users; [10] it was later described in Parkinson's disease. [11] Punding is a compulsion to perform repetitive mechanical tasks, such as sorting, collecting, or assembling and disassembling common items. [12]
Conditions besides Tourette syndrome that may manifest tics or stereotyped movements include developmental disorders, autism spectrum disorders, [29] and stereotypic movement disorder; [30] [31] Sydenham's chorea; idiopathic dystonia; and genetic conditions such as Huntington's disease, neuroacanthocytosis, pantothenate kinase-associated ...
The abnormal movements associated with choreas, dystonias, myoclonus, and dyskinesias are distinct from the tics of Tourette's in that they are more rhythmic, not suppressible, and not preceded by an unwanted urge. [24] [27] Developmental and autism spectrum disorders may manifest tics, other stereotyped movements, [95] and stereotypic movement ...
As explained in a 2008 study, in people with mood disorders there is a dynamic link between their mood and the way they move. [6] People showing signs of psychomotor agitation may be experiencing mental tension and anxiety, which comes out physically as: fast or repetitive movements; movements that have no purpose; movements that are not ...
