Objectives: Electroencephalography can still reveal a variety of focal abnormalities in different neurological diseases. EEG could represent an easy and economical tool to differentiate parkinsonisms when compare to neuroradiological studies. We want to report the EEG findings in a serie of diffuse lewy body disease and demented Parkinson ́s disease patients of our unit of movement disorders, in...

α‐synuclein (Lewy Body) pathology is commonly found in the enteric nervous system (ENS) of patients diagnosed with Neurocognitive Disorder with Lewy Bodies (NCDLB) and Parkinson’s Disease (PD). Lewy pathology in the ENS can produce symptoms of bowel immotility, including constipation, obstipation, and bowel impaction. These symptoms significantly reduce the quality of life for the patient, prod...

Clinical dementia associated with the appearance of Lewy bodies in the cerebral cortex has been recognized for over 40 years. Until the 1990s, however, cortical Lewy body disease was thought to be a rare cause of dementia. At that time, the advent of sensitive and specific immunohistochemical techniques for highlighting these elusive structures led to the recognition of cortical Lewy body disea...

Neuroinflammation is increasingly recognized as a key factor in the pathogenesis of neurodegenerative conditions. However, it remains unclear whether it has a protective or damaging role. Studies of Alzheimer's disease and Parkinson's disease have provided much of the evidence for inflammatory pathology in neurodegeneration. Here we review the evidence for inflammation in dementia with Lewy bod...

Lewy body pathology (LBP) is the pathological hallmark of Lewy body diseases, such as Parkinson's disease and Lewy body dementia. Recent studies have shed new light on the role of LBP, the interactions of LBP with concomitant pathologies, and the propagation of LBP from the olfactory bulb and enteric nervous system to the central nervous system. The intrinsic difficulty with identifying clinico...

(123)I-meta-iodobenzylguanidine (MIBG) has become widely applied in Japan since its introduction to clinical cardiology and neurology practice in the 1990s. Neurological studies found decreased cardiac uptake of (123)I-MIBG in Lewy-body diseases including Parkinson's disease and dementia with Lewy bodies. Thus, cardiac MIBG uptake is now considered a biomarker of Lewy body diseases. Although sc...
