It can take a long time to recover functioning with this serious condition, I am sorry to say.
What treatment is he getting? I'd make sure he is not shuffled off into the once a month injection!
5mg oral methylcobalamin daily on an empty stomach for a while and maybe for a LONG time.
PN can be due to other things too... gluten intolerance leading to malabsorption, is one. If another factor goes unidentified, recovery may be slower or minimal.
