Sexual and hypothalamic dysfunction in the postconcussional syndrome.

M Kosteljanetz, T S Jensen, B Nørgård

    Acta Neurologica Scandinavica
    |March 1, 1981
    PubMed
    Summary

    Postconcussional syndrome in males often involves brain damage, with many experiencing intellectual impairment and sexual dysfunction. Some show hormonal changes suggesting reduced sperm production, possibly linked to hypothalamic issues.

    Area of Science:

    • Neurology
    • Endocrinology
    • Neuropsychology

    Background:

    • Postconcussional syndrome (PCS) can manifest with diverse symptoms, including cognitive and sexual dysfunction.
    • The underlying organic basis of PCS, particularly in males, requires further investigation.

    Purpose of the Study:

    • To investigate the neurological, intellectual, and endocrinological profiles of males with well-developed postconcussional syndrome.
    • To explore potential correlations between cerebral changes, intellectual function, sexual dysfunction, and hormonal imbalances in PCS.

    Main Methods:

    • CT scans for cerebral atrophy assessment.
    • Psychometric testing for intellectual function evaluation.
    • Endocrinological assessments including laboratory tests and sexual function evaluation.

    Main Results:

    • 68% showed cerebral atrophy on CT scans.
    • 79% exhibited intellectual impairment, with 37% severely affected.
    • 58% reported sexual dysfunction (reduced libido and/or erectile dysfunction), more common with severe intellectual impairment.
    • 37% had increased follicle-stimulating hormone (FSH) levels, suggesting reduced sperm production.
    • No major hypothalamic-pituitary dysfunction was evident despite potential hypothalamic involvement.

    Conclusions:

    • High prevalence of cerebral atrophy and intellectual deterioration in PCS suggests organic brain dysfunction.
    • Sexual dysfunction in PCS is common and may correlate with intellectual impairment.
    • Elevated FSH levels indicate potential reproductive health issues in PCS patients.
    • While organic brain dysfunction is suggested, a direct causal link for all PCS symptoms remains to be established.
