There are other conditions that cause a person to have Dementia. The first mentioned on the NINDS sight is a brain condition called Creutzfeldt-Jakob disease, CJD. This one is a rarity. This brain condition only affects about one in a million people worldwide annually. It belongs to a family of diseases known as transmissible spongiform encephalopathies, TSEs.
To explain a bit further, the term spongiform pretty much means how it sounds. The human brain becomes filled with microscopic swellings that look like holes; sponge-like in appearance.
Medical professionals believe the condition for CJD and other TSEs are caused by infectious proteins called prions that become misfolded. Due to their presence they believe that they may trigger other normal proteins to also misfold. The chain reaction is a result of all of the misfolding.
The resulting factor is that all of the abnormal misfolded prion proteins tend to clump together. When this happens it damages the human brain.
The symptoms for CJD begin after the person turns 60. Most of the people diagnosed will die within the year. Scarier yet is when it is realized. Most of the time, CJD patients have no known risk factors for the disease; only about five-to-ten percent believe to have some sort of genetic mutation which causes it.
This is one scary form of brain condition causing Dementia or Dementia-like symptoms. In this case it is truly important for a caregiver to show the person that With Age Comes Respect – even if the person is not even old!
