Hi, your baby's case details are complex, & requires personal, detailed evaluation.
Please consult urgently a competent developmental Pediatrician or Pediatric Neurologist, as abnormal USG brain will require further developmental assessment (+/- neuroimaging) & Opthalmologist fundus examination.
If persistent neonatal jaundice is present, again blood workup after examining your baby.
Next Steps
Don't lose precious time, as early treatment (if correctable) is the key.
Health Tips
An abnormal cranial ultrasound should preferably be confirmed by better imaging modalities, especially for prognostication
