Hi!
I am sorry to hear about your son’s medical problems. The specialist used the term new born stroke because usually such defects occur at birth or shortly after. Sometimes a cause is found and at other times no cause is detected. In Wallerian degeneration, the axon of the nerve fiber is damaged and conduction of impulses is hampered. It may happen secondary to birth injuries. Please discuss in detail with your child’s neurologist as this is an antegrade degeneration, which means the process continues for life. Depending on the neurological, psychological and mental deficits, he will need a lot of support in form of physiotherapy etc. Take care!
The medical advice given should not be considered a substitute for medical care provided by a doctor who can examine you. The advice may not be completely correct for you as the doctor cannot examine you and does not know your complete medical history. Hence this reply to your post should only be considered as a guiding line and you must consult your doctor at the earliest for your medical problem.
Please note: he is a toddler but the Peds neuro only said "newborn stroke"
