TORONTO, Ontario (CTV Network) — A rise in teen girls developing “tic-like” behaviors could be linked to TikTok, along with an increase in anxiety and depression, resulting in symptoms similar to Tourette’s syndrome, doctors say.
In a study entitled “Rapid Onset Functional Tic-Like Behaviour in Young Females During the COVID-19 Pandemic,” published in the August issue of the journal Movement Disorders, researchers said when they began interviewing patients, many reported that the behaviors began after watching videos on platforms like TikTok and Youtube “showing persons allegedly having Tourette’s syndrome.”READ MORE: Ocean City Hit With 9 Inches Of Snow Saturday Morning
“However, many of these videos show movement and vocalizations not typically present in Tourette’s syndrome, including predominantly complex, variable and often continuous movements and elaborated and variable swearing and offensive phrases,” the study’s authors wrote.
Researchers from pediatric hospitals around the world found that referrals for tic-like behaviors “experienced a dramatic increase” during the pandemic, “almost exclusively” in girls aged 12 to 25, according to the study.
Since March 2020, referrals in Canada, the U.S., the U.K., Germany and Australia have reached 20 to 35 percent from one to two percent prior.
The study notes that the videos, which are posted by young people all over the world and have millions of views, but are not verified by experts, may “trigger tic-like behaviors in susceptible individuals.”
The study used data from 290 registry participants from a Calgary tic disorder clinic that was collected between 2012 and June 30, 2021 to describe the symptoms and demographic characteristics of the youth affected in this global phenomenon.
When the data was analyzed, 270 patients were found to have a primary tic disorder and 20 patients were found to have rapid onset “functional tic-like behaviors” or FTLBs.
Of the 20 patients with FTLBs, 17 had no history of previous tics, whereas three had mild simple tics earlier in childhood that were never detected.READ MORE: Winter Weather: Heaviest Snow Hits Eastern Shore, With Wind Gusts Possibly Exceeding 40 MPH
The rapid onset of the FTLBs all occurred in all participants during the pandemic period (after March 1, 2020) and all endorsed exposure to influencers on social media, mainly TikTok, with tics or Tourette’s syndrome.
The patients with FTLBs exhibited symptoms ranging from repetition of random words such as “knock knock,” or repetition of curse words, or obscene, offensive or derogatory statements, the study said. Others had complex hand and arm movements like clapping, pointing or throwing objects, and some exhibited behavior where they would hit or bang parts of their body, other people or objects.
Those with FTLBs were more likely to be female and have anxiety or a major depressive disorder diagnosis, but most have no definite history of previous tics. Those with FTLBs typically escalated in frequency and severity over a period of hours to days, prompting emergency room visits and even hospitalization, the study said.
The study notes that this phenomenon is a “noticeable departure” from the usual demographic and natural history of Tourette’s syndrome, which disproportionately affects boys with onset occurring between the ages four to seven.
“Global availability and increased usage of social media, particularly during the coronavirus disease 2019 pandemic, coupled with great social interest in the stage of Tourette’s syndrome, might lead to maladaptive gains further intensifying symptoms in susceptible individuals,” the study’s authors wrote.
Researchers posit that the pandemic has been a major source of stress and anxiety for people globally, resulting in increased mental health symptoms and demand for mental health services, with “increased social isolation and widespread utilization of social media” likely factors in a relevant portion of the patients reporting FTLBs.
“External factors like watching popular social media personalities’ videos portraying tics or tic-like behaviors may have instilled a belief that ‘tics’ may catalyze peer acceptance or even popularity,” the study says. “This exposure to tics or tic-like behaviors is a plausible trigger for the behavior.”
While social media exposure was reported in all of the patients with FTLBs at the Calgary clinic, that was not the case for every patient at the other global centres, which is why researchers are calling for a more in-depth study of the link between social media and the onset of symptoms and their severity in youth.MORE NEWS: New Details Surface About The Fire That Killed 3 Baltimore Firefighters
