    Area of Science:

    • Neurology
    • Psychiatry

    Background:

    • Presenile dementia is a debilitating condition.
    • Early diagnosis is crucial for management.
    • Depressive symptoms can precede or mask dementia.

    Purpose of the Study:

    • To investigate the prevalence of depressive illness manifestations in patients diagnosed with presenile dementia.
    • To understand how depression might mask presenile dementia.

    Main Methods:

    • Retrospective analysis of medical records of 50 patients with presenile dementia.
    • Radiological evidence of cerebral atrophy was a diagnostic criterion.
    • Assessment for antecedent depressive illness symptoms and diagnoses.

    Main Results:

    • Half of the patients exhibited symptoms of major affective disorder.

  • One-fourth received depressive spectrum diagnoses prior to the dementia diagnosis.
  • Psychiatric treatment history was common, more so in females, suggesting potential sex bias.

    • Conclusions:

    • Depressive illness is a common, often preceding, feature of presenile dementia.
    • Presenile dementia can be occult, masked by superimposed depressive symptoms.
    • Further research into sex-related biases in psychiatric presentation is warranted.
