[Psychogenic paraplegia/quadriplegia]

Area of Science:

• Neurology
• Psychiatry

Background:

• Psychogenic movement disorders can mimic organic neurological conditions.
• Accurate diagnosis is crucial to avoid unnecessary investigations and treatments.

Observation:

• Eight patients with clinically diagnosed psychogenic para- or quadriparesis were studied.
• Key diagnostic indicators included contradictory clinical findings and 'belle indifférence'.
• Normal electrophysiological, neuroradiological, and cerebrospinal fluid results were noted.

Findings:

• Contradictory findings such as normal muscle tone, reflexes, and alternating muscle power suggest psychogenic etiology.
• Paradoxical behavior, termed 'belle indifférence', is a characteristic feature.
• Normal results from extensive diagnostic testing further support a psychogenic diagnosis.

Implications:

• Overreliance on technical diagnostics risks misdiagnosis and costly interventions.
• Accurate clinical diagnosis of psychogenic paresis is crucial for appropriate patient management.
• Focusing on clinical signs prevents fixation on symptoms and unnecessary treatments.
