This case study highlights permanent cognitive deficits, including executive dysfunction and amnesia, following psychogenic malignant catatonia. These findings suggest catatonia may impact frontal lobe function long-term.

Area of Science:

  • Neuropsychiatry
  • Cognitive Neuroscience

Background:

  • Catatonia is a complex neuropsychiatric syndrome with varied motor, autonomic, and affective symptoms.
  • The long-term cognitive sequelae of catatonia remain poorly understood.
  • Psychogenic malignant catatonia represents a severe subtype requiring intensive management.

Observation:

  • A patient presented with psychogenic malignant catatonia.
  • Diagnostic evaluations included neurological and neuropsychological assessments, EEG, MRI, and sodium amytal interview.
  • Treatment involved electroconvulsive therapy (ECT).

Findings:

  • Following ECT, the patient exhibited persistent executive function deficits.
  • Anterograde amnesia was a significant and enduring cognitive impairment.

  • These deficits remained evident at a follow-up examination over two years post-treatment.

    • Implications:

    • The study suggests that catatonia, particularly severe forms, can lead to lasting cognitive impairments.
    • Findings support the conceptualization of catatonia as a syndrome with potential frontal lobe involvement.
    • Highlights the need for comprehensive cognitive assessment and management in catatonia survivors.
