Changsha hospital says man handled sudden dizziness as vertigo following an AI platform's prompts, stayed home three days and had a large cerebellar stroke

Xinmin Evening News reported on 25 June 2026 that Changsha Central Hospital treated a 52-year-old man who had sudden dizziness at home on 18 June. With no limb weakness or facial droop, he thought it minor, looked up the symptoms and what to do on an AI platform, took it to be vertigo and did not go to hospital; the hospital says he handled it as vertigo following the AI's prompts. Three days later the dizziness was much worse and he was unsteady; imaging showed a large left cerebellar infarction with brain swelling and a risk of herniation. He came through the critical phase after treatment. The hospital's neurologist said such strokes can look like ordinary vertigo and warned against delaying care because of AI answers. The AI platform is not named.

AI system as recorded: An unnamed AI platform the man used to look up his symptoms and what to do, as described by the treating hospital

What Happened

The account. On 25 June 2026 Xinmin Evening News, in a report carried by the Shanghai Observer app, said Changsha Central Hospital had treated a 52-year-old man who had sudden dizziness at home on 18 June. Because he had none of the familiar stroke signs such as limb numbness, weakness or a drooping mouth, he thought it minor, used an AI platform to look up the symptoms and what to do, took it to be vertigo and did not go to hospital. The hospital describes him as having handled it as vertigo following the AI's prompts.

The diagnosis. Three days later his dizziness had worsened markedly and he was unsteady and listless, and his family took him to the hospital. Imaging showed a large infarction of the left cerebellar hemisphere with brain swelling, a mass effect and a risk of herniation, and his condition was critical. After active treatment he came through the critical phase.

Limits. The only account is the treating hospital's, through one newspaper report. The AI platform, his question and its answer are not reported. The hospital's neurologist said cerebellar strokes can present only as dizziness and that late recognition can cost thrombolysis and early treatment, but did not say how the delay changed this patient's outcome.

Reported harm

A Changsha hospital says a man who handled sudden dizziness as vertigo following an AI platform's prompts stayed home three days and was then found to have a large cerebellar infarction in critical condition (hospital account).

How Harm Occurred

According to the treating hospital, a man treated sudden dizziness as vertigo following an AI platform's prompts and stayed home for three days; he was then found to have a large cerebellar infarction in critical condition.

Outcome

Resolved

After active treatment he came through the critical phase (hospital account, 25 Jun 2026). Lasting effects are not reported. No complaint, company response or legal action is reported.

What remains unknown

  • Which AI platform he used, what he typed and what it answered.
  • Whether earlier hospital care would have changed his treatment or outcome; the doctor speaks only in general terms.
  • His condition and any lasting effects after the critical phase.

What the evidence supports

AI involvement: reported. Changsha Central Hospital, through Xinmin Evening News, says the man used an AI platform to look up his dizziness and what to do, took it to be vertigo, and handled it as vertigo following the AI's prompts instead of going to hospital; three days later a large cerebellar infarction was found. The hospital connects the AI reading to the delay. The platform is not named and its answer is not quoted.

Reported After active treatment the patient came through the critical phase.

Causal attribution. Outcome as reported by the hospital.

Reported The hospital's deputy head of neurology said some cerebellar stroke patients show only persistent dizziness at first and are easily mistaken for ordinary vertigo, and that if it is not recognised in time patients can miss thrombolysis and early treatment of swelling.

Reported The doctor said AI consultation relies on what the patient types and cannot take a history, examine or image, and that patients must not diagnose themselves from AI prompts or delay seeing a doctor because of them.

Low Unidentified chatbot

Case report: teenager travelling in China took a nephrotoxic Aristolochia herbal remedy after a commercial chatbot told him it was safe, then had severe nausea

A case series published in the Journal of Family Medicine and Primary Care in 2026 by an author from the Faculty of Health Sciences at Ben-Gurion University of the Negev describes three cases in which chatbots misled patients or families. In the first, a 16-year-old boy with recurring abdominal pain had a severe episode while travelling in China and consulted a local alternative-medicine practitioner, who prescribed an herbal remedy containing Aristolochia (birthwort) extract. Unsure about the treatment, he asked a popular commercial chatbot, which reassured him that the remedy was safe and harmless. The therapy was stopped after three days because it did not help and he developed severe nausea. After returning home he learned that Aristolochia contains aristolochic acid, a nephrotoxin linked to irreversible kidney damage and cancer and banned in many countries. The report does not name the chatbot, say when this happened or report any kidney testing or lasting effect.

Medium Unidentified symptom-analysis tool

Zhejiang toddler hospitalised with pneumonia after his mother relied on an AI tool's asthma diagnosis and declined a chest X-ray (newspaper account)

A Guangming Daily feature on AI symptom-checking, republished by Bingtuan Daily on Sina Finance on 8 October 2026, recounts a case from August 2026 in Zhejiang and closes it with a quotation from the head of paediatrics at a provincial hospital, who says the family did not heed the doctor's advice. A three-year-old boy with a history of asthma was brought in; his mother had entered keywords such as allergy, asthma, cough and night-time wheezing into an AI tool, which quickly returned a diagnosis of an acute bronchial asthma attack. On that basis, the account says, she declined the chest X-ray the doctor recommended and insisted on taking home only nebuliser medication. Two days later the child's condition worsened with rapid breathing; on an overnight return to the hospital, examination found extensive inflammatory lesions in both lungs, and he was diagnosed with human metapneumovirus pneumonia with a superimposed bacterial infection and admitted as an emergency. The paediatrics head is quoted saying the illness would not have become so severe had the family listened earlier. The AI tool is not named. The case is told in the newspaper's voice, and the feature does not say where its account came from beyond the paediatrics head's quotation; no statement from the family is reported.

His son expressly cautioned that AI did not simply “kill” his father and that he might have resisted treatment without it.

Critical ChatGPT

Florida pastor's lawsuit alleges ChatGPT told him for weeks his symptoms were not dangerous before a near-fatal pulmonary embolism

Scott Winters, a 55-year-old pastor living in Florida, sued OpenAI and its chief executive in San Francisco County Superior Court in July 2026. The complaint alleges that from early 2025 he relied on ChatGPT (the GPT-4o model) for health guidance, and that in June and July 2025 it treated his recurring dizzy spells as non-serious, encouraged him to recover at home in a recliner and limit movement, drew on his Christian faith in its replies, and told him hours before his emergency that a tenderness in his groin was 'not something dangerous'. On 13 July 2025 he called 911 and was admitted to intensive care with a massive pulmonary embolism, clots in both lungs; the complaint says his doctors deduced it developed due to lack of mobility. He survived and says he lost his job, ministry and home. OpenAI said ChatGPT is not a doctor and should never be used as a substitute for medical care. The allegations are unproven and no ruling has been reported.
