Scientists Uncover Shared Genetic Roots of OCD, Tourette Syndrome, And Autism : ScienceAlert

The prenatal to postnatal development of our brains involves a complex cascade of chemicals, branching brain-signaling pathways, and unfolding neural cells – the evolution of a universe in microcosm. This incredibly intricate development can lead to potentially debilitating conditions like obsessive-compulsive disorder (OCD) and chronic tic disorders (CTDs), such as Tourette disorder (TD), which affect up to 2 percent of the population.
