Rheumatard arthritis

A mental side effect branched from rheumatoid arthritis that causes mental blocks on top of rheumatoid symptoms. Those with Rheumatard arthritis can suffer from mental judgement impairments, sudden use of poor grammar, and "brain farts".

My mom forgot to take her medication yesterday and her Rheumatard arthritis acted up; she thought her hemorrhoid cream was her toothpaste.
