V K Yeragani, G Hopkinson

    Canadian Journal of Psychiatry. Revue Canadienne De Psychiatrie
    |December 1, 1981

    Summary

    This case study highlights Klinefelter syndrome (XXY), a genetic condition, presenting with unusual behavioral episodes. Diagnosis involved ruling out epilepsy and identifying a personality disorder.

    Area of Science:

    • Genetics
    • Neuroscience
    • Psychiatry

    Background:

    • Klinefelter syndrome (47,XXY) is a common genetic condition in males, often associated with hypogonadism and infertility.
    • Behavioral and psychiatric disturbances can occur in individuals with Klinefelter syndrome, though specific presentations vary.
    • The differential diagnosis for episodic abnormal behavior includes neurological and psychiatric conditions.

    Observation:

    • A patient presented with recurrent, brief episodes of anxiety, perplexity, and auditory hallucinations.
    • During episodes, the patient exhibited non-epileptic physical manifestations like fist clenching.
    • Electroencephalogram (EEG) recordings were utilized to exclude a diagnosis of temporal lobe epilepsy.

    Findings:

    • The patient was diagnosed with Klinefelter syndrome (XXY).
    • Co-occurring conditions included a personality disorder and psychogenic attacks of abnormal behavior.
    • The clinical presentation mimicked certain epileptic seizures but was ultimately attributed to psychological factors in the context of Klinefelter syndrome.

    Implications:

    • This case underscores the importance of considering genetic conditions like Klinefelter syndrome in the differential diagnosis of unexplained behavioral abnormalities.
    • It highlights the complex interplay between genetic predispositions, personality factors, and psychogenic phenomena.
    • Further research into the neurobiological underpinnings of behavioral disturbances in Klinefelter syndrome is warranted.
