C M Filley, P E Jarvis

    Neurology
    |April 1, 1987
    PubMed
    Summary
    This summary is machine-generated.

    A man developed a specific delusion years after a head injury, linked to right hemisphere and bifrontal brain damage. This case highlights how brain injury can lead to delayed, specific false beliefs.

    Area of Science:

    • Neuroscience
    • Psychiatry
    • Neurology

    Background:

    • Traumatic brain injury (TBI) can cause diverse neurological and psychological deficits.
    • Understanding the long-term effects of TBI on cognitive and delusional thinking is crucial.

    Observation:

    • A 25-year-old male with a history of closed head injury and left hemiparesis developed a specific delusion.
    • The patient falsely believed his hospital was located near his home, over three years post-injury.
    • No prior history of psychosis or delusional thinking was noted, despite good recovery from the initial injury.

    Findings:

    • Clinical and neuropsychological assessments revealed right hemisphere and bifrontal brain pathology.
    • The findings suggest a correlation between specific cerebral pathology and the development of delusional beliefs.

    Implications:

    • This case demonstrates that specific delusional beliefs can emerge years after the initial brain injury.
    • It underscores the importance of considering delayed-onset psychiatric symptoms following TBI.
    • Further research into the neurobiological underpinnings of TBI-related delusions is warranted.
