Recent imaging studies in Tourette's syndrome (TS) have reported a loss of normal asymmetry in basal ganglia volumes. Our recent report of reduced midline sagittal cross-sectional area in TS suggests that altered lateralization may be widespread throughout the TS cerebrum. We report here our analyses of cerebral asymmetries of T2 (transverse or spin-spin) relaxation times derived from multi-echo/multi-planar/spin-echo magnetic resonance images in 14 adult TS subjects and 14 matched normal control subjects. T2 relaxation times were found to be asymmetric throughout the cerebrum of normal control subjects, with differences seen between T2 times of corresponding regions of both cerebral hemispheres that were small in magnitude (2-5%) but of a high degree of statistical significance in all regions examined. Our hypothesis of altered T2 relaxation time asymmetries in TS was confirmed in a multivariate analysis of variance, with post hoc analyses suggesting that group differences were attributable to specific asymmetry differences in the TS insular cortex and frontal white matter. Exploratory analyses revealed group differences in T2 times of the amygdala and red nucleus, as well as significantly lower ferritin levels in the TS group. These findings are discussed in relation to the previous TS volumetric studies, and the tissue characteristics that might produce normal and abnormal relaxation time asymmetries are considered.

Tourette's syndrome is a neurodevelopmental disorder clinically characterized by multiple motor and phonic tics. It is likely that a neurobiological susceptibility to the disorder is established during development by the interaction of genetic, biochemical, immunological, and environmental factors. This study sought to investigate the possible correlation of several immunological and biochemical markers with Tourette's syndrome. Children with Tourette's syndrome attending a tertiary pediatric medical center from May 2008 to April 2010, and healthy age-matched control subjects underwent a comprehensive biochemical and immunological work-up. Demographic data were abstracted from the medical records. Findings were compared between the groups and analyzed statistically. Sixty-eight children with Tourette's syndrome (58 males, 85.3%) and 36 healthy children (25 males, 69.4%) were recruited. Compared with the control group, the Tourette's syndrome group had significantly higher levels of ferritin (p = 0.01) and hemoglobin (p = 0.02), a lower level of zinc (p = 0.05), and a lower percentage of non-ceruloplasmin copper (p = 0.01). Analysis of the immunological markers revealed no significant between-group differences in IgA, IgM or IgG; however, IgE and IgG-4 levels were significantly higher in the Tourette's syndrome group (p = 0.04 and p = 0.02, respectively). Children with Tourette's syndrome have high levels of biochemical indices of oxidative stress and the quantitative immunoglobulins. These findings add to the still-limited knowledge on the pathogenesis of Tourette's syndrome and may have implications for the development of novel therapeutic modalities.
