I was in a terrible car accident 17 yrs ago, my brain was bleeding which left me with a 'head injury' or brain damage. I was in a coma for awhile and when I woke my short term memory wasnt working what so ever. My brother was an angel and brought me a tincture while I was int he hospital, gotu kola...I believe that is what helped me gain my short term memory back....that with loads of love and support! !7 yrs later my memory is excellent! Good luck!
