Dementia is not a diagnosis

Getting the right diagnosis is crucial to treating memory loss. Saying that someone has dementia is like saying that someone has a headache—it doesn’t imply anything about the underlying cause. Similarly, dementia can also be caused by things that are relatively benign, such as a vitamin deficiency or a thyroid disorder, or by more serious disorders such as Alzheimer’s disease or frontotemporal dementia.
