What are Some Examples of Nervous Tics?
Nervous tics are involuntary movements or twitches that most commonly occur in a person’s face, arms, or shoulders. The movements associated with nervous tics usually last for only a brief period of time and serve no purpose. Often, they are repetitive in nature. Typically, nervous tics involve twitching of the corner of the mouth, grimacing, twitching of the corner of the eye, blinking, or general repetitive movements with the arms, shoulders, or hands. Some nervous tics are caused by brain damage or damage to the nervous system. Many nervous tics, however, are caused by underlying psychological reasons that remain largely unknown. Some nervous tics are associated with Tourettes syndrome, which causes the individual to tic repeatedly and to exhibit outbursts of profane language. Often, those who exhibit nervous tics do so after experiencing an extreme psychological problem or emotional trauma.
