What causes a 4-month-old baby not to lift their head, not to look at things, or not to follow sounds?

Patient's question:

No

Doctor's answer:

The pre-treatment mainly involves strengthening rehabilitation training at home, and medication may not be very effective. The training time needs to be long, patience is required, and persistence is essential. It can be done under the guidance of a doctor, focusing on nutrition, avoiding illness, and especially preventing brain diseases.
