Ever since I've healed from having swine flu, i feel as if I'm mentally impaired?

I feel as if my ability to explain things has literally been cut in half, along with my vocabulary. I constantly forget short term things, such as the sentence that i was just about to type out. I used to have one of the best memories in my entire school, i mean, i could memorize 50-60 answers in 10 minutes if i needed to study for an upcoming test. Do you guys know anything i could do to get back on track with things, and fully recover?
