Spinal cord involvement in Lewy body-related α-synucleinopathies
2019
Context: Lewy body (LB)-related α-synucleinopathy (LBAS) is the neuropathological hallmark of several neurodegenerative diseases such as Parkinson disease (PD), but it is also found in neurologically asymptomatic subjects. An abnormal accumulation of α-synuclein has been reported also in the spinal cord, but extent and significance of the spinal cord involvement are still poorly defined.Objective: We aimed to review the studies addressing the spinal cord involvement of LBAS in healthy subjects and in patients with PD or other neurodegenerative diseases.Methods: A MEDLINE search was performed using following terms: “spinal cord”, “ α-synucleinopathy”, “α-synuclein”, “Lewy body”, “Parkinson’s disease”, “multiple system atrophy”, “neurodegenerative disorder”.Results: LBAS in the spinal cord is associated with that of the medullary reticular formation and locus ceruleus in the brainstem but not with that in the olfactory bulb and amygdala. The intermediolateral columns of the thoracic and sacral cord are the ...
