## 💡 Clinical Pearl
[Key clinical insight that helps distinguish this from similar conditions or aids diagnosis]
:::

Example:

::: {.callout-tip icon="false"}
## 💡 Clinical Pearl
The presence of **fever and encephalopathy** distinguishes ADEM from MS at initial presentation. ADEM is **monophasic**—recurrence should prompt reconsideration of diagnosis.
:::

Red Flag Warning (⚠️)

::: {.callout-warning icon="false"}
## ⚠️ Red Flag
[Critical warning about dangerous presentation or misdiagnosis]
:::

Example:

::: {.callout-warning icon="false"}
## ⚠️ Red Flag
**Thunderclap headache** with normal CT still requires lumbar puncture—10-15% of subarachnoid hemorrhages have negative CT in first 6 hours.
:::

Key Diagnostic Criteria (🎯)

::: {.callout-important icon="false"}
## 🎯 Key Diagnostic Criteria
**[Disease] Diagnosis requires:**
1. Criterion 1
2. Criterion 2
3. Criterion 3
4. Exclusion of alternative diagnoses
:::

Example:

::: {.callout-important icon="false"}
## 🎯 Key Diagnostic Criteria
**ADEM Diagnosis requires:**
1. First clinical event with acute/subacute onset
2. Encephalopathy (altered consciousness, behavioral changes)
3. Multifocal neurologic deficits
4. MRI: Large (>1-2 cm), poorly demarcated lesions
5. No better explanation (infection, metabolic, other demyelination)

📈 Enhancement #8: Evidence-Based Medicine Grades

Grading System:

[**Grade A, Strong**] - High-quality evidence, strong recommendation
[**Grade B, Moderate**] - Moderate-quality evidence, moderate recommendation
[**Grade C, Weak**] - Low-quality evidence, weak recommendation

Usage in Treatment Algorithms:

**Treatment Algorithm:**

1. **First-line:** [Treatment details] [**Grade A, Strong**]

2. **Second-line:** If first-line inadequate:
   - Option A [**Grade B, Moderate**]
   - Option B [**Grade C, Weak**]

3. **Supportive care:**
   - [Measure 1]
   - [Measure 2]

Example:

**Treatment Algorithm:**

1. **First-line:** High-dose IV methylprednisolone (20-30 mg/kg/day, up to 1 g/day) for 3-5 days → leads to rapid improvement in most patients [**Grade A, Strong**]

2. **Second-line:** If corticosteroid response inadequate, consider:
   - IVIG (2 g/kg over 2-5 days) [**Grade B, Moderate**]
   - Plasma exchange (5-7 exchanges) [**Grade C, Weak**]
