A 35-year-old woman in Germany was out in public when her right arm rose and extended on its own. Her brain implant's battery had run down, and the posture that followed, her doctors wrote, resembled a "Hitler salute." In February, a man with Tourette syndrome shouted a racial slur during a nationally televised awards show in London. Neither person chose what their body did.
The two incidents came from different disorders, but they expose the same problem. When a neurological symptom looks or sounds like a deliberate act, it can carry social and even legal weight. The German doctors wrote that awareness of such episodes matters "to mitigate psychosocial distress and stigma."
A Dead Battery and a Gesture That Is Illegal in Germany
The case, published online March 9 in Movement Disorders Clinical Practice by neurosurgeons at Hannover Medical School, involved a woman with right-sided hemidystonia, a disorder of sustained, twisting muscle contractions on one side of the body. It developed after she had herpes encephalitis at age 5.
Surgeons implanted a deep brain stimulation (DBS) electrode in a region of the thalamus called the ventralis intermedius nucleus, powered by a rechargeable pulse generator. Her motor score on the Burke-Fahn-Marsden Dystonia Rating Scale fell from 34 to 18, a 47% improvement.
At a follow-up visit two years after surgery, her mother described what had happened. The generator had discharged unexpectedly, and the dystonia returned abruptly, lifting and extending her right arm. Once the system was recharged and switched back on, the dystonia improved rapidly. Doctors could reproduce the sudden return simply by turning the device off.
The report is subtitled "An Embarrassing Situation," but the stakes went beyond embarrassment. Section 86a of Germany's Criminal Code bans using symbols of prohibited organizations, expressly including "forms of greeting,"with penalties of up to three years in prison or a fine. The authors wrote that the patient "feared possible legal consequences." Nothing in the report indicates she faced any.
The Hannover team also pointed out that involuntary gestures with socially inappropriate or illegal connotations have been reported in other movement disorders, including Tourette syndrome.
Tourette Tics Put the Same Problem on Live Television
That connection had already played out in front of millions. At the BAFTA Film Awards on Feb. 22, Scottish campaigner John Davidson, whose life inspired the film "I Swear," shouted the n-word as actors Michael B. Jordan and Delroy Lindo presented an award. The BBC aired the ceremony on a two-hour delay but did not edit the slur out.
Host Alan Cumming told the audience that "the tics you have heard tonight are involuntary." Davidson later told Variety, "My stomach just dropped," adding that he felt "a wave of shame and embarrassment." In a public statement, he said he was "deeply mortified if anyone considers my involuntary tics to be intentional or to carry any meaning."
In April, the BBC's complaints unit ruled that the broadcast breached editorial standards, though it found the error unintentional. It called the delay in removing the slur from the BBC's iPlayer streaming service "a serious mistake."
Offensive Tics Are Real but Much Less Common Than People Think
Popular culture often treats swearing as the defining feature of Tourette syndrome. The data say otherwise. A 2009 international analysis of 597 patients, drawn from 15 specialty sites in seven countries, found that coprolalia, or involuntary obscene or socially inappropriate speech, appeared at some point in 19.3% of males and 14.6% of females.
Copropraxia, involuntary obscene gestures, was rarer, at 5.9% of males and 4.9% of females. Both typically emerged around age 11, about five years after tics began.
The Centers for Disease Control and Prevention notes that swearing symptoms are not required for a diagnosis and that "most people with TS do not experience swearing or other socially inappropriate tics."
Dystonia carries its own social weight. A 2024 study of 114 adults with cervical dystonia found distress levels above general-population norms. Maladaptive coping strategies, such as behavioral disengagement, helped explain the link between stigma and poorer well-being.
When Involuntary Symptoms Meet Law Enforcement
The consequences can extend beyond embarrassment. The Tourette Association of America warns officers that they "may encounter someone with TS or Tic Disorders uttering obscenities, racial statements, or socially inappropriate phrases," stressing that "these tics, like all others, are involuntary." The group adds that tics "can increase in high-stress situations, such as being stopped by law enforcement."
In a 2023 survey by the Tourette Syndrome Association of Australia, people with the condition reported that 20% of first responders they encountered confused their tics with drug use, and 29% confused them with erratic or violent behavior. The survey came from an advocacy group and was not peer-reviewed. After the BAFTA incident, Reice Griffin, a 20-year-old Black woman with Tourette syndrome, told the Associated Press that "law enforcement is not well equipped to deal with Tourette syndrome."
The German authors cautioned that a single patient allows no strong conclusions, and they called for more research into what happens when long-term brain stimulation suddenly stops. People with brain implants who notice symptoms returning suddenly should contact their care team.
What ties these cases together is a gap between what observers see and what is actually happening in the brain. A gesture or a word can look like a choice. For a small but real group of patients, it is a symptom.
Key Questions Answered
What happened to the woman in the German case?
Her deep brain stimulator's rechargeable battery discharged unexpectedly, her hemidystonia returned abruptly, and her right arm rose into a posture resembling a Nazi salute. Recharging and restarting the device quickly improved the movement.
Why does the gesture matter legally in Germany?
Section 86a of the German Criminal Code bans using symbols of prohibited organizations, including forms of greeting, with penalties of up to three years in prison or a fine. The patient feared legal consequences, though the report does not say she faced any.
How common are offensive tics in Tourette syndrome?
In a 597-patient international study of clinic patients, involuntary obscene speech occurred at some point in about 15% to 19% of patients, and involuntary obscene gestures in about 5% to 6%. Most people with Tourette syndrome never have them.
Are these movements and words intentional?
No. Dystonic postures and tics are involuntary neurological symptoms. The Tourette Association of America stresses that offensive tics are just as involuntary as any other tic.
What remains unknown?
The German authors said a single case allows no strong conclusions and called for more research on what happens when long-term brain stimulation stops. There is also little rigorous data on how often people with movement disorders face legal or police consequences.
