Possible Early Dementia
Possible Early Dementia Overview
Dementia is a serious brain disorder that interferes with a person’s ability to carry out everyday tasks.
Alzheimer's disease usually begins with mild, slowly worsening memory loss. Many older people fear that they have Alzheimer's disease because they can’t find their eyeglasses or remember someone’s name.
MCI is a transitional zone between age-related memory loss and Alzheimer's disease. A person is often said to have MCI when he or she has Alzheimer's-like memory loss while the mind remains "sharp" otherwise.
There are other types of MCI, but the type involving short-term memory loss is the most common. Medical professionals call this type “amnestic” MCI. Amnestic has the same root as the word amnesia, meaning memory loss.
We are still learning about MCI. We don’t know how common it is, for example.
From studies in the brains of people with Alzheimer's disease or amnestic MCI, we know that the changes are similar. Therefore, amnestic MCI is generally considered to be due to an early form of Alzheimer's disease.

Perhaps the most important challenge in treating dementia is identifying cases (albeit uncommon) of reversible dementia such as chronic drug intoxication, vitamin deficiencies (B-12 and folate), subdural hematoma(s), major depression (causing forgetfulness), normal pressure hydrocephalus (NPH), and hypothyroidism.
