76  Functional Neurologic Symptom Prototype

76.1 Summary

  • A pattern of neurologic symptoms (e.g., weakness, tremor, non-epileptic events) not fully explained by structural disease and linked to functional disruption.

76.2 Prototype Features

  • Neurologic-type symptoms with inconsistent or variable findings.
  • Symptoms fluctuate with attention, stress, or context.
  • Significant distress or functional impairment.

76.3 Threshold Guidance

  • Use when functional neurologic symptoms are prominent and impairing after medical evaluation.

76.4 Expected Domain Profile

  • Somatic Distress and Interoception: moderate to high.
  • Anxiety and Threat Sensitivity: variable.

76.5 Time-Course and Trajectory

  • Fluctuating with stress or context.
  • May be episodic or persistent.

76.6 Differential and Red Flags

  • Neurologic disease requiring workup.
  • Substance or medication effects.
  • Seizure disorders or syncope.

76.7 Specifiers (treatment-relevant, non-prescriptive)

  • Course/time pattern (episodic, fluctuating).
  • Contributors (stress, trauma history, medical events).
  • Risk modifiers (falls, injury risk).

76.8 Measurement Prompts

  • Symptom frequency and functional impact tracking.
  • Activity or mobility limitations log.
