Restless legs in Tourette syndromeAbstract Restless legs syndrome (RLS) and Tourette's syndrome (TS) share some common features, including the phenomenology of sensations relieved by movements, but few studies have examined the links between RLS and TS. We examined RLS and other TS comorbidities in 144 probands with TS or chronic tics and their parents. RLS was present in 10% of probands and 23% of ... ...

Premonitory sensory phenomenon in Tourette's syndromeAbstract We administered a questionnaire designed to probe for premonitory sensations associated with motor tics to 50 patients with Tourette's syndrome (TS). Premonitory sensations were reported by 46 (92%) patients, and the most common sensation was an urge to move and an impulse to tic (“had to do it”). Intensification of premonitory sensations, if prevented from... ...

Deficits in rapid adjustments of movements according to task constraints in Parkinson's diseaseAbstract The role of the basal ganglia in the adaptive control of movement was investigated by unexpectedly perturbing movements in 8 patients with Parkinson's disease (PD) tested off medication and in 6 aged‐matched healthy subjects. Subjects performed two movement components simultaneously and without visual feedback: touching the nose with the finger while leanin... ...

Amantadine reduces levodopa‐induced dyskinesias in parkinsonian monkeysAbstract The antidyskinetic potential of the glutamate NMDA receptor channel blocker amantadine was evaluated in four levodopa‐primed parkinsonian monkeys using two different regimens (1.25 or 2.5 mg/kg administered subcutaneously twice daily for 3–6 days). When administered with a relatively low dose of levodopa, amantadine produced a near‐total suppression of chor... ...

Prevalence and Incidence of Huntington's Disease: An Updated Systematic Review and Meta‐AnalysisABSTRACT The incidence and prevalence of Huntington's disease (HD) based on a systematic review and meta‐analysis of 20 studies published from 1985 to 2010 was estimated at 0.38 per 100,000 person‐years (95% confidence interval [CI], 0.16–0.94) and 2.71 per 100,000 persons (95% CI, 1.55–4.72), respectively. Since 2010, there have been many new epidemiological studie... ...

The natural history of embouchure dystoniaAbstract Focal task‐specific dystonias are unusual disorders of motor control, often affecting individuals who perform complex repetitive movements. Musicians are especially prone to develop these disorders because of their training regimens and intense practice schedules. Task‐specific dystonia occurring in keyboard or string instrumentalists usually affects the ha... ...

Psychiatric symptoms associated with focal hand dystoniaAbstract Myoclonus dystonia and idiopathic dystonia are associated with a greater frequency of obsessive compulsive disorder (OCD) and major depression. We investigated the frequency of OCD in 39 patients with primary focal hand dystonia (FHD) using a semistructured interview. OCD and subsyndromal OCD was diagnosed in 5 of 39 (12.82%) patients with FHD, whereas OCD ... ...

Visual Sensory Processing is Altered in Myoclonus DystoniaABSTRACT Background Abnormal sensory processing, including temporal discrimination threshold, has been described in various dystonic syndromes. Objective To investigate visual sensory processing in DYT‐SGCE and identify its structural correlates....

Association and Familial Coaggregation of Idiopathic Dystonia With Psychiatric OutcomesAbstract Background Psychiatric comorbidities are common and major determinants of quality of life in idiopathic dystonia. Their prevalence estimates from service‐based studies are heterogeneous. Objective We explored the association between idiopathic dystonia and depress...

Executive cognitive deficits in primary dystoniaAbstract Primary dystonia is a disorder of movement for which no consistent pathophysiology has been identified; in the absence of evidence to the contrary, it is assumed to be cognitively benign. We have studied a clinically heterogeneous group of 14 patients with primary dystonia on a battery of neuropsychological tests. Despite well‐preserved speed of information... ...
