Predicting the chaos in Tourette Syndrome tics

Researchers have replicated and expanded on previous work to show that tics associated with Tourette syndrome have a fractal pattern, which can predict disease severity. This discovery could lead to a diagnostic tool for doctors to analyze tic patterns and diagnose patients with Tourette's

How do tics develop?

A team of researchers from Charité – Universitätsmedizin Berlin has identified a neural network that generates tics, which could lead to improved treatment of people with Tourette syndrome. The study found that targeting this network via deep brain stimulation can alleviate symptoms in patients.

Major genetic study confirms that many genes contribute to risk for Tourette's syndrome

A meta-analysis of multiple studies identifies hundreds of gene variants contributing to Tourette's syndrome, with more severe symptoms associated with increased risk variants. The study suggests a continuous spectrum of tic disorders and raises the possibility of predicting TS development in children with mild tics.

Tics are common in famous boys choir

A new study found that 35% of young singers in an elite choir exhibited tics during a performance. This discovery may indicate a relation between ticcing and exceptional motor skills, potentially leading to a reevaluation of the perception of tics as a disorder.

Brain's role in Tourette tics simulated in new computational model

A new computational model simulates the role of the brain in Tourette syndrome, suggesting that motor tics arise from interactions between multiple brain areas. The model predicts how dysfunctions in neural circuits can lead to an increased number of tics, which could aid in identifying new treatment targets.

Increased cognitive control in Tourette's syndrome

Researchers found that individuals with Tourette's syndrome make fewer error responses than neurologically normal peers, while responding just as fast to task demands, suggesting a compensatory change in cognitive control. This study challenges the widely held view that TS results from a failure of cognitive control mechanisms.

New research on Tourette's syndrome

Research suggests Tourette's syndrome is not a simple motor disorder, but rather a condition affecting the brain's circuits that control planning and decision making. The study found that individuals with Tourette's can anticipate and adjust to their tics, indicating intentional movement.
