Brain researchers say they have confirmed for the first time that a rare genetic mutation can cause some cases of Tourette syndrome, with the fault disrupting production of histamine in the brain.
The New Haven, CT, researchers at the Yale School of Medicine say the histamine effect "is a cause of the tics and other abnormalities of Tourette syndrome." Tics are repetitive movements and vocal sounds, and they are unwanted and involuntary - they cannot be controlled.
Publishing their research on mice in the journal Neuron, the authors raise the question of investigating treatment of Tourette syndrome by drugs that target histamine receptors in the brain.
Drugs with such a mode of action are already being explored by pharmaceutical companies for the treatment of separate brain disorders, schizophrenia and ADHD.
Information from the national gene database about histamine describes the chemical's role - it is a messenger molecule released by nerves, among other functions.
