Thank you for your query.
I deeply empathize with you and can understand your concern.
These are all problems of global developmental delay with mental retardation.
The basic functioning of the body is impaired due to inadequate brain development.
There are no medications for this problem. Recently pirecetam syrup may act better than placebo.
Other than that physiotherapy
exercises and speech therapy
are the only means to rehabilitate your child. Consult online support groups and specialised centres in your country for help.
Consult your doctor if the problem persists.
If you have any further queries you are free to consult me.
Hope this answers your query.
Wishing a speedy recovery.
Have a nice day.
