Unusual gestures

Unusual gestures refer to any purposeless or repetitive physical movements that are not part of normal behavior. They are often seen in people with mental illnesses such as schizophrenia, autism, and depression. Unusual gestures can include hand-flapping, rocking, and finger-flicking. They can also include repetitive movements such as spinning, pacing, or repeating certain words or phrases. These gestures can start suddenly and can become more frequent and more intense over time.
