### 1. Potential Differential Diagnoses

For a 13-year-old male presenting with insomnia, consider the following:

- **Primary sleep disorders:**  
  - Delayed sleep phase syndrome (common in adolescents)  
  - Restless leg syndrome  
  - Obstructive sleep apnea (less common but possible)

- **Psychiatric/psychological causes:**  
  - Anxiety disorders  
  - Depression  
  - Adjustment disorder (e.g., stress from school or social situations)

- **Medical causes:**  
  - Hyperthyroidism  
  - Asthma or allergies causing nocturnal symptoms  
  - Chronic pain

- **Medication/substance-related:**  
  - Stimulant use (including caffeine, ADHD medications)  
  - Illicit substance use

- **Environmental/behavioral:**  
  - Poor sleep hygiene (e.g., excessive screen time before bed)  
  - Irregular sleep schedule

### 2. Recommended Diagnostic Tests

- **Clinical assessment:**  
  - Detailed sleep history (onset, duration, pattern, sleep environment, bedtime routine)  
  - Review of systems (for psychiatric, respiratory, or endocrine symptoms)  
  - Medication and substance use history  
  - Family/social history

- **Screening tools:**  
  - Sleep diary (1-2 weeks)  
  - Pediatric Sleep Questionnaire  
  - Screening for depression/anxiety (e.g., PHQ-9, GAD-7 for adolescents)

- **Physical examination:**  
  - General exam, including ENT (for signs of sleep apnea), neurological, and thyroid assessment

- **Laboratory tests (if indicated by history/exam):**  
  - Thyroid function tests  
  - CBC (if restless leg syndrome suspected, to check for iron deficiency)

- **Further studies (if indicated):**  
  - Polysomnography (if sleep apnea or periodic limb movement disorder suspected)

### 3. Urgency Level

**Medium**  
- Insomnia in adolescents is common but can significantly impact functioning, mood, and academic performance.  
- If associated with severe mood symptoms, suicidality, or significant daytime impairment, urgency increases to **High**.

---

### 4. Key Observations and Clinical Notes

- Insomnia in adolescents is often multifactorial; a thorough history is essential.
- Consider behavioral and environmental causes first, as these are most common.
- Screen for depression/anxiety, as these are frequently associated with insomnia in this age group.
- Assess for signs of sleep-disordered breathing or other medical conditions if suggested by history/exam.
- Family and school stressors should be explored.

### 5. Red Flags to Watch For

- **Suicidal ideation or severe depression**
- **Hallucinations, mania, or psychosis**
- **Significant weight loss, night sweats, or systemic symptoms**
- **Symptoms suggestive of sleep apnea (e.g., loud snoring, witnessed apneas, daytime somnolence)**
- **Unexplained neurological findings**
- **Substance abuse**
