Movement disorders in young people related to ADHD

Genetic analysis based on one man

The scientific article, which has just been published in Journal of Clinical Investigation, is based on one patient only. Neurologists and psychiatrists have examined the male patient, who is 45 years old and has suffered from serious movement disorders since he was in his 20s. Furthermore, he has had various mental problems since childhood. When he was 36 years old, he was diagnosed with ADHD:

"It was a great relief for the patient and his family to get a genetic explanation of a disease that has affected him since childhood," says Freja H. Hansen.

But can the results be used in a wider perspective?

"We will, among other things, create a mouse model with the same genetic deficiencies, and we expect it to become a new disease model for parkinsonism and mental disorders. We hope that this will help us find new and better ways of treating these diseases," says Ulrik Gether.

"We would like to examine the frequency of mutations in the DAT-encoding gene in both children and young adults with serious movement disorders. This knowledge can clarify whether the DAT gene can be used in the genetic investigation of patients. Genetic examinations of embryos may also be relevant for some families," concludes Freja H. Hansen.
