Failure to Diagnose a Stroke FAQs

The failure to diagnose a stroke can result from errors during triage, examination, testing, communication, or interpretation of results. Emergency personnel may fail to document symptom onset, a clinician may perform an incomplete neurological examination, or a patient may be discharged without appropriate brain imaging. A provider may also rely too heavily on an initial CT scan even though certain ischemic strokes may not yet be readily apparent, fail to obtain additional imaging when clinically indicated, or misinterpret the study. In other cases, a stroke may be mistaken for vertigo, migraine, anxiety, medication effects, intoxication, or another condition. Delays can also occur when staff do not communicate abnormal findings promptly or request a specialist consultation. Whether any particular decision was negligent depends on the information available at the time and the accepted standard of care under those circumstances.

A stroke interrupts normal blood flow or causes bleeding in the brain, and brain tissue can be damaged quickly. The correct treatment depends on whether the stroke is ischemic or hemorrhagic, when symptoms began, the location and severity of the event, imaging findings, and the patient's medical condition. Some patients with an ischemic stroke may be candidates for medication intended to dissolve a clot, while selected patients with certain large-vessel blockages may benefit from a clot-removal procedure. These treatments are not appropriate for every patient and must be administered within applicable medical criteria. A delay may cause a patient to lose eligibility for a time-sensitive intervention or allow a larger area of the brain to become permanently injured. Resulting harm can include paralysis, impaired speech, cognitive limitations, difficulty swallowing, vision loss, chronic pain, loss of independence, and the need for long-term rehabilitation or personal care.

A poor medical outcome alone does not establish malpractice. Under New York law, a patient generally must prove that a healthcare provider departed from accepted medical practice and that the departure proximately caused the injury. In a delayed diagnosis case, the evidence may need to show that a reasonably competent provider should have recognized the possibility of a stroke, ordered appropriate testing, obtained a specialist consultation, or initiated treatment sooner. The patient must also demonstrate that the delay caused additional harm. This may involve proving that timely action probably would have reduced the extent of brain injury, preserved a treatment option, or improved the patient's functional outcome. Qualified medical experts ordinarily review the records, imaging, symptom timeline, treatment criteria, and resulting disabilities to address the standard of care and causation. The analysis must distinguish damage caused by the stroke itself from additional damage attributable to negligent delay.

A patient injured by the failure to diagnose a stroke may be able to seek compensation for both financial and personal losses. Economic damages can include emergency care, hospitalization, rehabilitation, medication, assistive equipment, home modifications, nursing services, future medical treatment, lost wages, and reduced earning capacity. When a patient can no longer perform household tasks or live independently, the cost of necessary assistance may also be considered. Non-economic damages may compensate for pain and suffering, emotional distress, physical impairment, loss of enjoyment of life, and the profound frustration associated with communication or cognitive limitations.

New York generally requires a medical malpractice action to be commenced within two years and six months of the negligent act or omission or, when all legal requirements are satisfied, the end of continuous treatment for the same illness, injury, or condition. Unlike certain failure-to-diagnose cancer claims, a missed stroke diagnosis does not ordinarily receive New York's special cancer discovery rule. A patient therefore should not assume that the filing period begins when the error is discovered. Claims against a public hospital, municipality, or government-affiliated provider may be subject to shorter deadlines and separate notice requirements. The applicable date can also depend on the identity of the defendants and the course of treatment. Anyone considering a claim based on the failure to diagnose a stroke should speak with an attorney promptly so that the deadline can be evaluated and important evidence can be preserved.
