Identify Areas of The Brain
The research, carried out by a Spanish team, was awarded first prize at the III World Congress on Controversies in Neurology.
A group of Spanish researchers has identified the areas in the brain that are impaired when a neurodegenerative process is initiated and appears mild cognitive impairment. “The findings are relevant because they give us clues about the brain areas that we should look to in future make an early diagnosis of Alzheimer’s disease,” said Juan Antonio Hernandez Tamames, director of the Laboratory of Medical Image Analysis and Biometrics URJC center where images were analyzed in the study.
The research, carried out by the Universidad Rey Juan Carlos (URJC), in collaboration with Queen Sofia Foundation Alzheimer’s Project and the Department of Basic Psychology, National University of Distance Education (UNED), analyzed a total of 40 patients -18 and 22 healthy subjects with mild cognitive impairment-selected sample of 140 individuals used in the study, three-year Early detection of MCI and progression to Alzheimer’s Disease. Analysis of MCI subtype, markers, and Risk Factors. Patients with cognitive impairment were classified as amnestic, amnestic and multidomain not, ie those with amnesia problems and problems in the execution of daily tasks.
The work, which has received the first prize at the III World Congress on Controversies in Neurology held in the Czech Republic last October, shows that in subjects with mild cognitive impairment amnestic begins turning parahippocampal damage the brain – an area close to the memory and memories in the brain.
However, in patients with non-amnestic mild cognitive impairment deteriorates first thing is the anterior cingulated. Finally, in patients with impaired both areas are damaged multidomain-turn parahippocampal and cingulated. The three findings are consistent with each other and with clinical symptoms.
According to research, this could be due to the fact that multidomain cognitive impairment is a more advanced stage of Alzheimer’s that can occur after a mild cognitive impairment, either amnesia or amnesia. These findings also can be easily distinguished from other dementias that present with symptoms similar to Alzheimer’s, such as vascular dementia or Lewy body dementia.
