It is problematic to try to compare the concussion symptoms of different people. Every concussion is different. The progression and regression of symptoms often gives most experience with a wide range of symptoms, just not in the same way.

You need to learn new study habits. Your old memorizing system will not work. It helps to use two or more senses to memorize. Read the information (visual), say it out loud (auditory) and write it down (tactile). This should help you memorize information. It creates three different memory indexes of the same information. It should help.

Also, you may find that certain times of day are better. It may help to be in a quiet and visually bland room. Get some ear plugs. The yellow foam cylinders are my favorite. Blocking out ambient sounds will help your brain focus.

I lost my photographic memory and had to learn new ways to retain information. It takes extra effort but you can do it.

Let us know how else we can help.

My best to you.
