Hi, Welcome to HealthcareMagic Forum.
You should be repeating the CT Scan
or MRI head to rule out any Brain Tumor
or if to see if the Meningitis
is completely cured. If it is meningitis and is completely not cured, there are chances of his symptoms recurring back. The cause for this has to Found out like TB Meningitis or something else as treating the cause will definitely help. If TB Meningitis is confirmed, he will have to take Medicines for 6 Months at least for complete cure. Take him to a Neurologist
for a second opinion
at the earliest.
I wish him Good Health, Good Luck.
