What are the Different Types of Dementia?

As we age and see ourselves or loved ones beginning to struggle with recalling either important or basic items of information, concern grows regarding the onset of dementia.  How do you know what type of dementia you or you loved one might be experiencing?

The good news is that it is fairly simple to determine the differences in dementia.  Two main types of dementia exist, one that affects the outer layers of the brain that play a role in thinking and memory, and the other that affects the parts of the brain that is beneath the cortex.

The first issue called Cortical dementia emerges from a disorder that affects the cerebral cortex.  This problem characteristically presents itself with severe memory loss and the inability to remember words or understand language.   As you may guess, the resulting diagnosis is typically Alzheimer’s disease.

The latter issue called Sub-Cortical dementia, reflecting the problems beneath the cortex, usually results in difficulties with speed of thinking and the ability to initiate activities.  Typically, these issues are in connection with Parkinson’s or Huntington’s disease.

In addition to these two issues, in some rare cases, both parts of the brain can be affected with a disorder called Multi-Infarct dementia.  With this disorder, the symptoms that typically occur include memory loss, language, judgment and behavior.  This disorder is usually a result of a series of strokes suffered by an individual.

Given our longer life expectancies, the prevalence of dementia increases as we all age.  With each of the types of dementia, a variety of forms of treatment exist depending on your or your loved one’s symptoms.  Because of improvements in diagnostic technology, dementia is increasingly recognizable and treatable.

Should you or your loved one have concerns, do not hesitate to contact your healthcare provider with questions.
