Diagnostic value score: 33

Top Condition Groups Causing This Symptom

Mental Health

6 linked conditions

•Temporal relationship with psychosocial stressors
•Sleep, concentration, and mood triad
•Need to exclude organic causes before attribution

Anxiety Disorder Depression Panic Disorder Post-Traumatic Stress Disorder (PTSD)Premenstrual Dysphoric Disorder (PMDD)Obsessive-Compulsive Disorder (OCD)

Neurological

3 linked conditions

•Sudden vs progressive neurologic deficit
•Focal deficits, consciousness changes, and meningeal signs
•Headache phenotype and trigger pattern

ADHD (Attention Deficit Hyperactivity Disorder)Substance Use Disorder Autism Spectrum Disorder (ASD)

Cardiovascular

2 linked conditions

•Character of pain and exertional trigger
•Hemodynamic instability, pulse pattern, and blood pressure
•ECG and cardiac biomarkers trend

Hyperthyroidism PCOS (Polycystic Ovary Syndrome)

General Internal Medicine

2 linked conditions

•Prioritize red flags and severe progression first
•Use focused history + exam to define the leading organ system

Magnesium Deficiency Borderline Personality Disorder (BPD)

Renal and Urologic

1 linked conditions

•Dysuria, hematuria, flank pain, and urinary pattern
•Infection signs vs obstructive colic pattern
•Urinalysis profile with imaging correlation

Urgent Causes

Anaphylaxis

Dangerous but Less Common

No high-signal entries available for this block.

What Changes the Differential

Age modifiers

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

Severity and acuity

•Red-flag triage first: rule out urgent causes such as Anaphylaxis.

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., Anxiety + Insomnia, Anxiety + Fatigue, Anxiety + Poor Concentration) materially alter the differential.

When Testing Is Needed

Immediate testing when red flags are present

•Vital signs and focused triage examination
•Pulse oximetry and ECG
•Basic blood panel (CBC, CRP, electrolytes, glucose)
•Immediate imaging based on dominant red flags

Group-directed workup

•Structured clinical assessment
•Basic metabolic screen
•Medication/substance review
•Sleep and mental-health questionnaires
•Focused neurologic exam
•CT/MRI when red flags are present
•Lumbar puncture when indicated
•Glucose and electrolytes
