New Study Techniques Reveal Insights Into Dementia with Lewy bodies (DLB) and Corticobasal Syndrome
lewy bodiesA new study on Dementia with Lewy bodies (DLB) and Corticobasal Syndrome (CBS) entitled “Differentiating between visual hallucination-free dementia with Lewy bodies and corticobasal syndrome on the basis of neuropsychology and perfusion single-photon emission computed tomography” was published in Alzheimer's Research & Therapy by Michael R Misch, part of Dr. Mario Masellis’ group from the L.C. Campbell Cognitive Neurology Clinic at the Sunnybrook Health Sciences Centre in Toronto, Canada. Dementia with Lewy Bodies (DLB) and Corticobasal Syndrome (CBS) are atypical parkinsonian disorders characterized by fronto-subcortical and posterior cognitive dysfunction. Lewy body pathology can be detected based on visual hallucinations, although these features are not observed in all cases of DLB and are rare in Corticobasal Syndrome. These two pathologies can normally be clinically distinguished during the mid-stages of the disease, but in the early stages they usually have identical clinical characteristics and therefore a precise diagnosis is more difficult.  Thus, additional information through neuroimaging and neuropsychological evaluation could help to differentiate DLB wi
