Too often, family members of a patient are told by a doctor that their loved one is diagnosed with “dementia”. Hearing this, the family members walk away with a feeling of relief that at least Alzheimer’s disease is not the cause behind the mental problems their loved one has been going through lately.

This is where they are wrong. Dementia is an umbrella term for a number of mental diseases, under which Alzheimer’s diseases rates at the top. Today, doctors use the word “dementia” instead of “senility” to describe the symptoms a person might be going through such as memory difficulties, decline in cognitive function, confusion, etc.

What is the Difference between Alzheimer’s and Dementia?

A good analogy for explaining the term dementia is “fever”. When a person’s body temperature rises, we say that the person is sick. Though we have figured out the symptom, we have yet to discover the cause. Dementia tells us that there is something wrong with the brain but we still have to find out what is causing the cognitive difficulties.

In other words, dementia is a clinical presentation that defines a disease.

Symptoms of Dementia

Dementia causes memory difficulties in cognitive functioning of the following areas:

  • Language
  • Attention
  • Problem solving
  • Spatial skills
  • Judgment
  • Planning
  • Organization

There comes a time when the cognitive functioning declines to such a level, where patients experience difficulty in their daily lives including areas in occupational and social functioning.

Identifying the difference between Alzheimer’s and dementia is a confusion, which is not just faced by the patients or family members but by health care providers too.
