My mom is only 57 y/o, has RA, hypothyroidism, osteoporosis - but has been showing some symptoms, like forgetfulness, mood shifts, disorientation, balance issues, repeating stories, no appetite, blood pressure getting low day after day, is anemic (they don't know why ) and many others. Neurologist made a brief memory test on her, she could answer correct just her kids names and then dr. asked me to write down her symptoms and come back in two months. Isn't that too long?
