It is a mysterious brain disorder can be confused with the preliminary stage of Alzheimer's, but does not deprive patients of their memories, but the words to talk about them.
It is called primary progressive aphasia (PPA), and scientists said they are looking for better ways to diagnose this disease little known. That will help people whose thoughts are lucid but can not express them to receive proper care.
Even many doctors know little about this rare type of aphasia, and spread the problem is key to improving care. There is a study underway to try to slow the progression of the disease by electrical stimulation of the affected region of the brain.
Language and speech are enormously complex. 100 requires just talk activate muscles between the lungs and lips to produce at least 14 different sounds per second, said Dr. Joseph Duffy, of the Mayo Clinic.
A stroke or brain injury can often leave the person with problems to produce sounds or words. The APP occurs for a different reason, because the region of the brain that controls language is sick and degenerates, resulting in communication difficulties -a first glance similar to those caused by dementia.
