HIV-2 Positive with MND. Can survive?

Hi doctor,Its been 10 months iam roaming around the globe to save my dad.He was diagnosed with MND in january, from their on wards we are using "Rilutor, Maxmalla and Vitamin-D tablets and improvement was not observed.In search of the solution gone through many referral books about MND and came to know stages of MND but one month back through twitter we came to know that "Stem cell therapy" will halt the disease. We decided to do that as a generic rule gone through blood tests and finally we came to know that my dad is HIV-2 positive were it took long time to digest it. In simple words my questions are 1.HIV with MND is possible technically?If yes can the patient will be recovered with ART medicines(Lopimmune and duovir tablets) Many articles say 50% chances 2.Should We stop using rilutor tablets? 3.Will panchakarma treatment is helpful along with allopathy medicines?? 4.Once if it spreads to mouth part how long can the patient can survive? Note:CD4 count is 657 as of now
