Hi. I m 17 years old and i have a few concerns which I want to clarify. A few months ago when i was on holiday , I had a very high fever and began to have some serious seizures as well as got very aggressive so im told. Now that I m back and have began college , I ve noticed that my short term memory has gone very bad. I mean before , I would rarely forget. Now my short term memory is pretty bad , but i keep telling myself that it is due to me not concentrating. Even my long term memory isn t great however before I would never forget anything that has been dedicated to my long term memory. The other day , my vision went blurry all of a sudden. And occasionally I get really bad headaches to the side of my head. Background noise is now becoming much more noticeable. Is there anything to be concerned out?
