Are Motor Skills and Motor Inhibitions Impaired in Tourette Syndrome? A Review
Tourette syndrome (TS) is a neurodevelopmental motor disorder described as an inability to inhibit unwanted motor movements. This article reviews research on the execution and inhibition of voluntary motor movements in TS. Over last two decades, a number of studies have addressed the structural and functional deficits associated with this syndrome. Only a limited number of studies have assessed...
متن کاملFine motor skills in adult Tourette patients are task-dependent
BACKGROUND Tourette syndrome is a neuropsychiatric disorder characterized by motor and phonic tics. Deficient motor inhibition underlying tics is one of the main hypotheses in its pathophysiology. Therefore the question arises whether this supposed deficient motor inhibition affects also voluntary movements. Despite severe motor tics, different personalities who suffer from Tourette perform suc...
متن کاملTic & Tourette Syndrome and Motor Disorders
Motor disorder refers to neuropsychiatric disorders such as abnormal movements, meaningless repetitive movements, and impairment in acquisition and performance of motor skills. Motor disorder was included as a sub-category of neurodevelopmental disorder chapter in the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) [1]. DSM-5’s motor disorders include tic disorders (T...
متن کاملImpaired inhibition of prepotent motor actions in patients with Tourette syndrome.
BACKGROUND Evidence that tic behaviour in individuals with Tourette syndrome reflects difficulties inhibiting prepotent motor actions is mixed. Response conflict tasks produce sensitive measures of response interference from prepotent motor impulses and the proficiency of inhibiting these impulses as an act of cognitive control. We tested the hypothesis that individuals with Tourette syndrome s...
متن کاملMotor excitability during movement preparation in Tourette syndrome
Tourette syndrome (TS) is a neurodevelopmental disorder characterized by the occurrence of motor and vocal tics. TS has been linked to the impaired operation of cortical-striatal-thalamic-cortical circuits that give rise to hyper-excitability of cortical motor areas, which may be exacerbated by dysfunctional intra-cortical inhibitory mechanisms. That said, many individuals gain control over the...
