“…Their medication uptake remained the same throughout the therapy. Our sample size compares to most of past ERP research published earlier, which used comparable TD patients samples at n ¼6 (van de Wetering et al, 1985), n ¼10 (Johannes et al, 2001a(Johannes et al, , b, 2003, n ¼12 (Johannes et al, 1997), n ¼15 (Thibault et al, 2009) andn ¼24 (van Woerkom et al, 1994).…”

“…Nonetheless, patients with GTS also showed an intact P300 in an auditory oddball Van de Wetering et al, 1985;Oades et al, 1996) and a Stroop task (Johannes et al, 2003), while a larger P300 amplitude was elicited during a counting oddball task, where no motor responses are required (Thibault et al, 2008). In the current paradigm, the incompatibility condition required that inhibition of the automatically activated response occur concurrently with comparison, abortion and retrieval of the correct motor program, which likely required dividing attentional resources, and which in GTS, delayed stimulus evaluation and categorization processes.…”

Gilles de la Tourette syndrome (GTS) is a neuropsychiatric disorder with childhood onset presenting with multiple fluctuating motor tics and one or more phonic tics. A significant proportion of people suffering from GTS are still symptomatic in adulthood and present other emotional and cognitive difficulties, along with motor problems that often accompany these comorbid conditions. The nature of these difficulties is still poorly understood and multiple comorbidities are often inadequately controlled. The current study investigates both stimulus evaluation and motor processing in GTS while controlling for comorbidity. Fifteen adults with GTS and 20 control participants were matched on gender, laterality and intelligence. The P300 component, the no-go anteriorization (NGA) as well as the stimulus and response-locked lateralized-readiness potentials (S-LRP, R-LRP) were elicited during a stimulus-response compatibility (SRC) paradigm. The standard version of the Stroop Color-Word Test (SCWT) was also administered. Reaction times showed that participants with GTS processed both the SRC and the SCWT more rapidly than the control group, while producing a delayed P300 peak latency. The GTS group also showed faster S-LRP onset in response to the incompatible and faster processing of interference in the SCWT. There was also a tendency toward a greater frontal shift of the NGA in the GTS group. The P300 latency showed that with GTS patients, stimulus evaluation occurs later whereas the overlapping pre-motor response selection processes occur faster. Our findings are congruent with a probable cortical motor over-activation hypothesis of GTS involving faster motor program selection in processing conflicting SR configuration.

“…However, models derived from pharmaco logic information in this fashion inevitably suffer from a lack of anatomic specifIcity. Electrophysiologic studies demonstrate only nonspecifIc and nonlocalizing abnor malities (Van de Wetering et al 1985;Sweet et al 1973); in spite of reports of histologic or biochemical altera tions in postmortem studies of TS brains (Balthasar 1956;Haber et al 1986;Singer et al 1990), no unequiv ocal neuropathologic changes have yet been associated with the disorder. The pathogenesis of Tourette's syn drome remains nearly as obscure as when the illness was fIrst described more than a century ago (Gilles de la Tourette, 1885) .…”

Regional metabolic rates for glucose estimated using [18Flfluorodeoxyglucose positron-emission tomography were compared in 16 drug-free patients with Tourette's syndrome (TS) and 16 age-and sex-matched normal volunteers. Tourette's syndrome patients were characterized by decreased normalized metabolic rates in paralimbic and ventral prefrontal cortices, particularly in orbitofrontal, inferior insular, and parahippocampal regions. Similar decreases were observed in subcortical regions, including the ventral striatum (nucleus accumbenslventromedial caudate) and in the midbrain. Published by Elsevier Science Publishing Co., Inc.655 Avenue of the Americas, New York, NY 10010These changes were more robust and occurred with greater frequency in the left hemisphere. They were associated with concomitant bilateral increases in metabolic activity the supplementary motor, lateral premotor, and Rolandic cortices. Effects of prior exposure to neuroactive drugs did not account for these findings. These results suggest that an altered relationship between limbic-related regions of the cortex and striatum and cortical regions involved in the initiation of movement may play a role in the pathogenesis of this illness.
