What could be the reason for a 9-month-old baby's slow neurodevelopment?

Patient's question:

No

Doctor's answer:

Treatment improves motor function by increasing joint mobility, adjusting muscle tone, and enhancing motor control, coordination, strength, and endurance, thereby enhancing the ability to perform daily activities. Additionally, medication can be used; common medications include neurotrophic drugs for the brain and muscle relaxants. Medication treatment should only be used when necessary.
