- Motor assessment improvements were noted in patients aged 2 to 4 years.
- Common adverse reactions include vomiting, back pain, and headache.
Guideline-Based Recommendations
Diagnosis
- Diagnosis is based on clinical presentation and genetic testing for GFAP mutations.
Management
- Zilganersen is indicated for treatment in pediatric and adult patients.
Monitoring & Follow-up
- Monitor for adverse reactions, including aseptic meningitis.
Risks
- Potential risks include vomiting, back pain, cough, headache, and post-lumbar puncture syndrome.
