Brain perfusion anomalies in rapid eye movement sleep behavior disorder with mild cognitive impairment
Movement Disorders, 08/01/2012
Vendette M et al. – The study showed specific patterns of posterior cortical hypoperfusion and hyperperfusion in some brain areas in patients with Rapid eye movement (REM) sleep behavior disorder and mild cognitive impairment, similar to those found in Parkinson's disease dementia and dementia with Lewy bodies. This suggests the presence of an identifiable neuroimaging marker of synucleinopathy in REM sleep behavior disorder with mild cognitive impairment.
