Hi,
Seizure and loss of already attained milestones occur in a condition called neuro-degenerative disorder. Truly speaking, this is not a single disease but a group of conditions with neuro-regression. Frequently, despite thorough investigations, we won't be able to find out a specific course, as new diseases are being discovered year by year and the list we have now is incomplete and yet to expand.
The
hypoglycemia she had after delivery could be a reason, but in that case we expect
MRI to be abnormal and although milestones can be delayed, loss of already gained ones is unusual. In such cases, what we can offer is symptoms oriented supportive measures like early stimulation to maximise development, seizure control with drugs, maintain proper nutrition, vision and
hearing assessment and management. Your doctor will guide through these steps.
Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Muhammed Aslam TK, Pediatrician
