How Can Cognitive Problems Causing Memory And Concentration Lapses Be Treated?

Hi I think i might have some cognitive problems. Sometimes I keep forgetting words, I can read something (like a text book) and I forget everything i have read (I can't remember a single word) I'm having some problems with my concentration, I can "fall" out of the stuff I'm reading extremely easily and when i read it feels like im reading the words not what it says / the content. Sometimes I feel quite disoriented and I can forget why I walked into the room, and I can forget where I left stuff. I'm having difficulties learning new things
