|Genetic and environmental factors play a role in the etiology of Tourette syndrome, but the exact causes are unknown. The first symptoms usually occur in the head and neck area and may progress to include muscles of the trunk and extremities. Motor tics generally precede the development of vocal tics and simple tics often precede complex tics. Most patients experience peak tic severity before the mid-teen years with improvement for the majority of patients in the late teen years and early adulthood. Approximately 10 percent of Tourette syndrome affected has a progressive or disabling course that lasts into adulthood.
International Journal of Emergency Mental Health and Human Resilience is one of the best scholarly journals on Tourette syndrome. The journal follows a stringent peer-review process that aims to improve the overall quality of the published content and attracting more number of citations. In collaborative efforts, the journal is focusing on Psychological trauma, Resilience, Psychotherapy, Dissociation, related psychological, social and medical research.
