Dementia is a decline in intellectual performance from the person’s previous level of functioning and always involves memory loss. In addition, there is typically a loss of problem-solving ability and other aspects of abstract thinking. Dementia describes a group of symptoms and is not the name of a disease that causes the symptoms.
Causes of Dementia
Dementia can be caused by a number of diseases, and they may be treated differently. Some causes of dementia can be reversed and some can not.
For example, a vitamin B-12 deficiency, malnutrition, and drug interactions can cause dementia and can be treated, eliminating the symptoms. That is why it is so important to get a medical diagnosis when dementia occurs.
Alzheimer’s disease, the most frequent cause of irreversible dementia is progressive and causes structural changes in the brain. The second most common form, called multi-infarct dementia, is caused by a series of small strokes that may be undetectable when they occur, but do cumulative damage to the brain.
It is important to remember that dementia is not a normal part of aging. Some memory loss is to be expected as we age. Occasional forgetfulness or taking a bit longer to recall a name or the location of an object is common and no cause for concern.
Dementia, however, is notable because of the extent, pattern, and persistence of the problem. People suffering from dementia experience it differently; some will display certain symptoms and some will display others. How do you identify changes associated with dementia?

Behaviors Typical of Early Dementia
Often, an individual struggling with early stage dementia will exhibit characteristic behaviors, such as:
- Denial and attempts to cover up the mistakes
- Withdrawal from favorite activities or social interactions
- Paranoia and general agitation, sometimes exhibited as blaming others or accusing them of stealing
- Uncharacteristic personality changes
- Poor judgment and confusion
What to Expect
Family members must try to remember that many of these behaviors and personality changes are outside the person’s control and their capabilities may fluctuate from day to day. However, individuals with early stages of dementia are often able to participate in their treatment, in family decisions and in planning for the future. Therefore, it is critical for the person with dementia to get a thorough medical examination as soon as possible in order to confirm the diagnosis. Even though most dementia is irreversible, much can be done to enhance the quality of life for persons with dementia and for family members.
