The aim of this postmortem study was to compare, in Parkinson's disease subjects with and without bilateral subthalamic nucleus deep brain stimulation (STN-DBS), the loss of pigmented neurons within the substantia nigra and pathological alpha-synuclein density within the SN and other brain regions.
PD subjects were identified from the Arizona Study of Aging and Neurodegenerative Disorders database (STN-DBS = 11, non-DBS = 156). Pigmented neuron loss scores within the substantia nigra as well as alpha-synuclein density scores within the substantia nigra and 9 other brain regions were compared, the latter individually and in summary as the Lewy body brain load score.
DBS subjects had higher alpha-synuclein density scores within the substantia nigra, olfactory bulb, and locus ceruleus, as well as higher total Lewy body brain load scores when compared with non-DBS subjects. No differences in substantia nigra pigmented neuron loss scores were found.
STN-DBS subjects tend to have higher alpha-synuclein density scores, but do not have a differential loss of substantia nigra pigmented neurons. © 2016 International Parkinson and Movement Disorder Society.
本尸检研究的目的是比较接受双侧丘脑底核脑深部电刺激(STN-DBS)和未接受该刺激的帕金森病患者黑质中色素神经元的丧失情况,以及黑质和其他脑区中病理性α-突触核蛋白的密度。
从亚利桑那衰老与神经退行性疾病研究数据库中识别出帕金森病患者(接受STN-DBS治疗的患者=11例,未接受治疗的患者=156例)。比较黑质中色素神经元丧失评分以及黑质和其他9个脑区中α-突触核蛋白密度评分,后者单独比较,并汇总为路易体脑负荷评分。
与未接受DBS治疗的患者相比,接受DBS治疗的患者黑质、嗅球和蓝斑中的α-突触核蛋白密度评分更高,路易体脑负荷总分也更高。未发现黑质色素神经元丧失评分存在差异。
接受STN-DBS治疗的患者往往具有更高的α-突触核蛋白密度评分,但黑质色素神经元的丧失并无差异。©2016国际帕金森病和运动障碍协会。
