ALS Disability

Hi, Professional friends recently my close friend is diagnosed with ALS last year and I want to make sure he gets all tax credits possible please let me know what all credits and benefits are available to him we already got T2201 from the doctor. they have made some renovation for easy access with in-home. and His brother has been helping him and he has paid him for the support. I would like to know all the credits and deductions he can get as every dollar is valuable

I would highly appreciate every ones input. Thanks in advance
