Tics are a neurological condition characterized by involuntary and repetitive movements or sounds. Many people experience tics. Children, for example, may have transient tics that clear up on their own later in life. But why do they happen at all? Scientists think a buildup of neurotransmitters in parts of the brain helping plan and control movement may play a role. Researchers are working to unravel the neuroscience of tics and how they can be treated.
