Case: 23 years old female is admitted to ICU with anxiety, depression, and suicidal ideation. Family reported recent symptoms of tic. Psychology service was consulted, and they diagnosed patient with "TikTok tics."
Answer: Interestingly, there was an increase in reporting of functional tics during COVID-Pandemic. The probable cause is mental health issues while in isolation. A particular form is called "TikTok tics." Most young females between the ages of 15 and 25 have been reported to have acute, complex vocal and motor tics involving large-amplitude arm movements. Associated symptoms were a tendency to self-injury, anxiety, depression, and coprolalia (use of wide range of odd words and obscenities). The common underlying feature is the long hours of viewing online videos depicting tic-like behaviors.
Coprolalia is a prominent distinguishing feature between functional and nonfunctional tics.
