Tourette-like tics vanish in mice treated with histamine

Yale scientists produced increased grooming behavior in mice that may model tics in Tourette syndrome and discovered these behaviors vanish when histamine—a neurotransmitter most commonly associated with allergies—is ...

Genetics

First clear-cut risk genes for Tourette disorder revealed

Tourette disorder (also known as Tourette syndrome) afflicts as many as one person in a hundred worldwide with potentially disabling symptoms including involuntary motor and vocal tics. However, researchers have so far failed ...

Brain chemical aids tic control in Tourette Syndrome

A chemical in the brain could potentially be harnessed to help young people with Tourette Syndrome (TS) to overcome the physical and vocal tics associated with the neurological disorder, say researchers.

A shift in the code: New method reveals hidden genetic landscape

With three billion letters in the human genome, it seems hard to believe that adding a DNA base here or removing a DNA base there could have much of an effect on our health. In fact, such insertions and deletions can dramatically ...

Neuroscience

Researchers find rare genetic cause of Tourette syndrome

A rare genetic mutation that disrupts production of histamine in the brain is a cause of the tics and other abnormalities of Tourette syndrome, according to new findings by Yale School of Medicine researchers.
