YouTuber Jan Zimmermann, Known for His Honesty About Tourette’s, Found Dead at 27

26 November 2025

Beloved German YouTuber Jan Zimmermann, celebrated for his candid and humorous videos about living with Tourette's syndrome, has died at the age of 27. His family announced that he passed away suddenly on November 18 from an epileptic seizure.

Zimmermann first gained widespread recognition through the YouTube channel Gewitter im Kopf (which roughly translates to “Storm in the Head”). Launched in 2019 along with his friend Tim Lehmann, the channel drew in millions of viewers at last count, over two million subscribers with its frank and often humorous portrayal of life with Tourette’s including the involuntary tics and vocalizations that come with the condition.

Through a mix of video blogs, conversations, and personal storytelling, Zimmermann used his platform to demystify a neurological disorder often misunderstood showing the world how one can live, laugh, and find community even with “Gisela,” the affectionate name he gave to his condition. Over the years, he and Lehmann documented the ups and downs, shared medical experiences, and turned personal vulnerability into public empathy.

In 2022 Zimmermann underwent a surgical intervention, a “brain pacemaker” procedure in an effort to reduce the severity of his tics. After the surgery, he reportedly experienced a reduction in symptoms, and for a time stepped away from social media. But the duo returned earlier this year with renewed energy, and fans welcomed them back.

On November 24, his family shared a statement expressing grief and gratitude. “Jan died very suddenly and unexpectedly,” they wrote. “His humor, his honesty, and his big heart were gifts he shared with everyone.” They thanked supporters for their condolences and promised to honor his memory.

Authorities in Bonn, Germany confirmed that Zimmermann was found dead in his apartment in Königswinter on the evening of November 18. An autopsy ruled out foul play, and officially concluded that the cause of death was a seizure closing the investigation.

The news sent shockwaves through his community of fans, fellow creators, and advocates. On social media platforms, tributes poured in many thanking him for his vulnerability, courage, and the comfort he brought to people who struggled with similar conditions. “Rest in peace our icon,” wrote one fan. Another commented: “Thank you for always sharing your shine with us.”

Beyond entertainment, Zimmermann’s legacy lies in representation. For many viewers living with neurological or mental health challenges, his channel offered not just visibility but a validation of experience. He turned a private condition into public conversation, showing that neurological difference shouldn’t be a source of shame or silence.

His passing is a tragic reminder of the unpredictability of life and the fragility behind even the most resilient of spirits. For the community he nurtured, the laughter, the honest disclosures, and the hope he offered remain powerful testaments.
