Fig. 1From: Sleep disturbances and gastrointestinal dysfunction are associated with thalamic atrophy in Parkinson’s diseaseCorrelations between thalamic atrophy and non-motor symptoms in Parkinson’s disease patients. Loss of thalamic volume correlated with a higher NMSQ (r = − 0.42, P = 0.042) and NMSS (r = − 0.47, P = 0.014) total scores; b higher NMSS domain 2 sleep/fatigue (r = − 0.36, P = 0.042) and NMSS domain 6 gastrointestinal tract dysfunction (r = − 0.36, P = 0.042) subscoresBack to article page
