Neuropaediatrics, Tourette syndrome.

Main research areas

Since 2005, we have followed a large clinical cohort of children and adolescents with Tourette syndrome longitudinally with focus on symptom severity, comorbidity, neuropsychological consequences, neuroimaging and genetics.
Since 2014, we have offered a new non-pharmacological treatment for tics, behavioural therapy, and evaluate ongoing its effect in a research project.
Since 2017, we have established a cohort of twins with Tourette syndrome, who we examine clinically and genetically.

Besides Tourette syndrome, I am interested in other neuropaediatric topics and I am planning research projects on cerebral palsy, headache and sleep disorders.

Current research

  • "Behavioural therapy in Tourette syndrome"
    Since 2014, we have treated patients with Tourette syndrome with behavioural therapy. In this project, we examine the short-term and long-term efficacy, and the efficacy of behavioural therapy via telemedicine
  • "Twins study"
    We include all twins from the Danish Twins Register with a diagnosis of tics or Tourette syndrome. The participants are examined clinically and genetically
  • Genetics study
    All patients from the Danish Tourette Clinic are included ongoing in this project, that examines the influence of genes and environment on the development of Tourette syndrome
  • Longitudinal study 
    A large clinical cohort started in 2005 was reexamined after 6 years with regard to development of tics, comorbidity, neuropsychology and psychosocial aspects of Tourette syndrome. On a cross-sectional basis this cohort, the psychiatric comorbidity, abuse of drugs, alcohol and cigarettes, and quality of life is examined.
  • "Neuropsychology in Tourette syndrome"
    Several neuropsychological aspects of Tourette syndrome are examined, among others intelligence and time perception.
