Actor Liev Schreiber was hospitalized in New York City on Sunday after a sudden, severe headache led his doctor to recommend immediate evaluation, sources told TMZ. The 58-year-old Ray Donovan star was admitted overnight as doctors ran comprehensive tests to determine the cause.
Schreiber reportedly contacted his physician as the headache intensified, describing it as unusually strong. Concerned it could indicate a neurological event, the doctor advised immediate hospital evaluation. Schreiber followed the recommendation and was kept for observation through Monday while specialists conducted imaging and neurological assessments. As of Monday afternoon, physicians had not identified a specific diagnosis.
Sources who spoke with TMZ said Schreiber remained alert and stable. He did not show impaired speech or movement, and reportedly “is able to speak and walk without any issues and has the full use of his limbs.” Those indicators reduce the likelihood of a major stroke, though doctors continue testing until serious conditions are ruled out.
Representatives for Schreiber have not commented, and it is unclear whether he will require further monitoring. TMZ reported that, despite the uncertainty, medical staff have maintained caution, using several diagnostic tools to evaluate potential neurological causes.
The weekend incident follows a previous medical episode in 2024, when Schreiber experienced temporary amnesia while performing in Doubt: A Parable. He described the event on Late Night with Seth Meyers as beginning with a severe headache and resulting in memory issues.
The memory lapse worsened backstage; Schreiber realized he could not recall his co-star Amy Ryan’s name, which caused concern about a possible stroke. He attempted to go onstage but found himself unable to remember his lines.
Doctors later diagnosed the episode as transient global amnesia (TGA), a rare neurological condition that results in sudden memory loss and confusion. Schreiber described how an MRI—a scan that creates detailed images of the brain—revealed no brain bleed or structural abnormality. In a summary of additional remarks, he said the neurologist (specialist in disorders of the brain and nerves) reassured him that the episode was reversible and unlikely to recur.
The Cleveland Clinic notes TGA is typically triggered by migraines, exertion, stress, or sudden temperature changes. It mainly affects middle-aged and older adults, and symptoms usually resolve within 24 hours.
While no link has been made between Schreiber’s previous TGA episode and his current hospitalization, neurologists say severe headaches can come from many causes—some benign but some requiring prompt evaluation. Because of this variability, physicians often recommend immediate testing for sudden or unusual symptoms.
Schreiber, known for Ray Donovan, Spotlight, Scream, and Broadway work, has remained busy over the last year. As of Monday evening, there were no updates on his upcoming projects or filming commitments.
Further information is expected as test results come in, but for now, Schreiber’s condition appears stable, and sources emphasize he remains fully responsive. Fans and colleagues have expressed relief online as they await more news about his health.
