Respected User, hi I evaluated your query thoroughly.
*Any neurological case requires detailed physical examination with sensory
motor evaluations from all aspects ; relevant investigations of EMG , NCV,
MRI , finding further reasons for underlying pathologies.
*After final diagnosis only line of treatment for outcome is decided & then
comes prognostic issues.
*Till then - give him high protein, iron diet to boost up his immunity
- light exercises at home.
- avoid
smoking / alcohol / any abuse substances if any.
- avoid
stress /
anxiety.
- have adequate sleep of 8 hours.
- multivitamins , multiminerals , antioxidants , Methylcobalamine containg
agents help to some extent.
