It doesn't have to get better to not be dementia. I agree that if there is a sudden increase, you should first ask yourself about recent lifestyle changes (sleep, alcohol/drugs, medicines, recent general anesthesia) and ask a doctor if you're still concerned. But although a sudden increase can be a symptom of something else--especially in combination with other symptoms--a gradual increase beginning in mid-life is a symptom of the "terminal illness" of ordinary aging.
