@pfraz118 Hello & welcome to Mayo Connect. It sounds like your brother has dealt with a lot, and it's very good of you to step up to help him.
The way for your brother to find care at Mayo is to go to this link:

There is a questionaire to respond to, then your application will be reviewed and you will be contacted, usually within about 5 business days. After an interview, he may be asked to submit medical records so they can decide if there is a good likelihood of being able to help.
