How to recover meningitis after effects

Dear Doctor,
I'm a male 26,height 180cm and weight 59 kg.I suffered meningitis at the age of 22.After a two week allopathic treatment I recovered.Meningitis is fully cured but I had some other problem.That are double vision,and mild walking imbalance.It almost recovered after allopathic and ayurvedic treatment.But still some problem of total weakness,food swallowing problem,take very small quantity of food,very slow in eating,become too tired and sleepy after some physical work,forgetting things and names,cann';t studying and by heart lessons,after all OCD and depression.For this I take SSRIs and antidepressants under the prescription of a psychiatrist.Doing the treat ment for one year.Some problems like ocd and depressive nature are 90% recovered 50% other problems but forgetting things or names and studying problem has no change .I stopped all medicine as doctor said and recover it naturally.But there is no improvement.Now my problem is cannot study anything .Lost interest in studing,feel mind is occupied some other things,forget studying names and lessons,i know the words it is in my tongue's tip but cannot spell the words,too slow in understanding,forget English language skills and grammar.I cannot study even a word or paragraph.So totally disappointed.I heard have better medicines for this problems...so consider my problem and prescribe some good medicine ...
thanking you
