First get evaluation by a cognitive specialist such as a neuropsychologist. You might benefit from a full testing protocol. The results can be assessed by either a psychiatrist or neurologist. We do have memory enhancing meds, but also items that improve focus and concentration. All of this is potentially readily handled by experienced practitioners.
