From your description here it seems that the problems you are facing are memory impairment, poor concentration, and a state of confusion or daze. It seems that these problems have been present with you for some time now. The precise cause and the reasons behind such a presentation will require a thorough evaluation in terms of a detailed history, thorough interview of you, some neuropsychological assessment, and some laboratory investigations. You are correct in saying that these are neural psychic presentations and labelling these as brain problem. Do not delay a consultation with a psychiatrist or a neurologist. Early assessment and intervention is the key to management of such problems. Hope this helps you.. Wishing you an early recovery..
