Do you ever get confused about the different types of dementia you hear about? While Alzheimer's is the most common type, it's not the only one. Shortly after I was offered the position of the Alzheimer's guide for About.com, my health editor and I discussed changing the topic name to Alzheimer's/Dementia because of the many people that are affected by other kinds of dementia.
One of those is vascular dementia. Depending on which source you use, either vascular dementia or Lewy body dementia is the second most common type of dementia. Vascular dementia is related to blood flow, and although it may develop slowly over time, it also can develop suddenly after a stroke.
For more information about vascular dementia, here's an article I wrote recently comparing Alzheimer's disease and vascular dementia: What's the Difference Between Alzheimer's and Vascular Dementia?
Also, here are a few articles describing some of the other types of dementia.
I am disappointed that you do not include dementia that can occur in adults after long-term undiagnosed and untreated thyroid dysfunction. Too many doctors dismissed my symptoms as depression that I correctly diagnosed as endocrine imbalance, hormone imbalance, pre-diabetes, thyroid dysfunction and finally “brain not working properly”. After correct treatment for thyroid dysfunction, and my personal treatment of vitamins, physical exercise and brain exercises, my dementia has improved. But I am left with brain damage (and symptoms) that show on a scan. Medical negligence does occur, as does brain damage from untreated thyroid dysfunction.
Dear hh,
Thanks for bringing up this possible cause of dementia symptoms. I’m so sorry to hear of your experience with the medical community, but glad you have been persistent in your quest for answers and treatment. As noted here, thyroid problems can cause several symptoms, including forgetfulness and difficulty concentrating. Early treatment can often resolve some of those symptoms.
Also, for others reading this, a blood test of your thyroid functioning should be included in the tests you undergo when you’re being screened for dementia. Please see this article for more information: Blood Tests for Alzheimer’s Disease
hh, thanks for writing to highlight this concern. I have no doubt that your willingness to share your experience is helpful to others, so thank you!
