    Summary
    This summary is machine-generated.

    Electroencephalogram (EEG) abnormalities were found in nearly half of the 46 transsexual individuals studied. Women with gender dysphoria showed higher rates of these EEG findings compared to men.

    Area of Science:

    • Neuroscience
    • Endocrinology
    • Psychiatry

    Background:

    • Transsexualism, now understood as gender dysphoria, involves a discrepancy between assigned sex and gender identity.
    • Previous research has explored potential biological underpinnings of gender dysphoria, including neurological factors.

    Purpose of the Study:

    • To investigate the prevalence of electroencephalogram (EEG) abnormalities in individuals with transsexualism.
    • To explore potential correlations between EEG findings, demographic factors, and clinical characteristics in this population.

    Main Methods:

    • A consecutive series of 46 transsexual patients (35 male, 11 female) underwent electroencephalogram (EEG) assessments.
    • Data on age, sex, presence of personality disorders, and self-reported sex drive were collected and analyzed.

    Main Results:

    • 48% of participants exhibited EEG abnormalities, with an additional 24% showing borderline abnormalities.
    • Women demonstrated a significantly higher proportion of EEG abnormalities compared to men.
    • Individuals with EEG abnormalities were younger at study inception and their gender dysphoria was recognized earlier by families.

    Conclusions:

    • EEG abnormalities are prevalent in individuals with gender dysphoria, particularly in women.
    • Earlier age of onset and recognition of gender dysphoria may be associated with neurological differences.
    • Further research is warranted to understand the neurobiological correlates of gender dysphoria.
