Tics are involuntary, repetitive movements or sounds that can arise from a combination of genetic, neurological, and environmental factors. They are often associated with conditions like Tourette syndrome but can also occur independently. Stress, excitement, or fatigue can exacerbate tics, and they typically emerge in childhood. While the exact cause is not fully understood, brain chemistry and function, particularly involving neurotransmitters like dopamine, play a significant role.
