What you may notice
Symptoms can overlap with other conditions and vary between people.
- Loss of developmental skills
- Muscle weakness
- Exaggerated startle

Understanding care
Clinical care may include neurological and genetic assessment with supportive feeding, respiratory and family care. A qualified clinician decides which investigations and options fit the individual situation.
When to seek help
Loss of skills or worsening movement needs prompt specialist review. New seizures, serious swallowing or breathing difficulty, or reduced consciousness requires urgent emergency care.
For severe breathing difficulty, collapse, suspected stroke, or another emergency, call local emergency services immediately. In India, call 112.
