What Changes the Differential

Age modifiers

  • •Age changes baseline risk: pediatric, adult, and older patients have different top causes.

Severity and acuity

  • •Escalating severity, hemodynamic instability, or neurologic compromise should always override watchful waiting.

Timing and pattern

  • •Timing matters: onset speed, duration, and recurrence pattern help separate benign from high-risk causes.

Associated symptoms

  • •Associated symptom clusters (e.g., Irritability + Insomnia, Irritability + Poor Concentration, Irritability + Fatigue) materially alter the differential.

When Testing Is Needed

Immediate testing when red flags are present

  • •Focused examination with baseline labs if symptoms persist
  • •Escalate to urgent workup when red flags appear

Group-directed workup

  • •Structured clinical assessment
  • •Basic metabolic screen
  • •Medication/substance review
  • •Sleep and mental-health questionnaires
  • •ECG
  • •Troponin
  • •Blood pressure in both arms
  • •Echocardiography when indicated
