Proton Magnetic Resonance Spectroscopy for the Early Diagnosis of Parkinson Disease in the Substantia Nigra and Globus Pallidus: A Meta-Analysis With Trial Sequential Analysis.

ABSTRACT: This study aimed to investigate the metabolic changes in globus pallidus (GP) and substantia nigra (SN) during the early stage of Parkinson disease (PD) using magnetic resonance spectroscopy (MRS). PubMed, Embase, Web of Science, and Chinese National Knowledge Infrastructure were searched till November 2018. Eligible trials comparing early metabolic changes in GP and SN in patients with PD vs. controls were included. The mean differences with 95% confidence intervals were estimated with either fixed- or random-effects models using Review Manager 5.3 software. Trial sequential analysis was performed using TSA 0.9.5.10 beta software. Finally, 16 studies were selected from the search. Overall, the N-acetyl aspartate-to-creatine ratio showed a significant difference between patients with early-stage PD and healthy controls. The overall heterogeneity was P < 0.00001, I ² = 94% in GP and P = 0.0002, I ² = 74% in SN. The results revealed that MRS could be a more sensitive imaging biomarker in the diagnosis of early-stage PD.

Project description:To characterize changes in the magnetic resonance (MR) relaxation properties of progressive supranuclear palsy (PSP) and tissue from neurologically normal brains by using high-resolution (21.1-T, 900-MHz) MR microscopy of postmortem human midbrain and basal ganglia.This HIPAA-compliant study was approved by the institutional review board at the Mayo Clinic and informed consent was obtained. Postmortem tissue from age-matched PSP (n = 6) and control (n = 3) brains was imaged by using three-dimensional fast low-angle shot MR imaging with isotropic resolution of 50 μm. Relaxation times and parametric relaxation maps were generated from spin-echo and gradient-recalled-echo sequences. MR findings were correlated with histologic features by evaluating the presence of iron by using Prussian blue and ferritin and microglia burden as determined by a custom-designed color deconvolution algorithm. T2 and T2*, signal intensities, percent pixels (that could not be fitted in a pixel-by-pixel regression analysis due to severe hypointensity), and histologic data (total iron, ferritin, and microglia burden) were statistically analyzed by using independent sample t tests (P < .05).PSP specimens showed higher iron burden in the cerebral peduncles and substantia nigra than did controls. However, only the putamen was significantly different, and it correlated with a decrease of T2* compared with controls (-48%; P = .043). Similarly, substantia nigra showed a significant decrease of T2* signal in PSP compared with controls (-57%; P = .028). Compared with controls, cerebral peduncles showed increased T2 (38%; P = .026) and T2* (34%; P = .014), as well as higher T2 signal intensity (57%; P = .049). Ferritin immunoreactivity was the opposite from iron burden and was significantly lower compared with controls in the putamen (-74%; P = .025), red nucleus (-61%; P = .018), and entire basal ganglia section (-63%; P = .016).High-field-strength MR microscopy yielded pronounced differences in substantia nigra and globus pallidus of PSP compared with control brains. Histologic data also suggested that the predominant iron in PSP is hemosiderin, not ferritin. Iron in the brain is a contrast enhancer and potential biomarker for PSP.

Project description:Maintaining and manipulating sequences online is essential for daily activities such as scheduling a day. In Parkinson's disease (PD), sequential working memory deficits have been associated with altered regional activation and functional connectivity in the basal ganglia. This study demonstrates that the substantia nigra (SN) integrity correlated with basal ganglia function and sequencing performance in 29 patients with PD (17 women) and 29 healthy controls (HC, 18 women). In neuromelanin-sensitive structural MRI, PD patients showed smaller SN than HC. In a digit ordering task with functional MRI, participants either recalled sequential digits in the original order ('pure recall') or rearranged the digits and recalled the new sequence ('reorder & recall'). PD patients performed less accurately than HC, accompanied by the caudate and pallidal hypo-activation, subthalamic hyper-activation, and weakened functional connectivity between the bilateral SN and all three basal ganglia regions. PD patients with larger SN tended to exhibit smaller ordering-related accuracy costs ('reorder & recall' versus 'pure recall'). This effect was fully mediated by the ordering-related caudate activation. Unlike HC, the ordering-related accuracy cost correlated with the ordering-related caudate activation but not subthalamic activation in PD. Moreover, the ordering-related caudate activation correlated with the SN area but not the daily dose of D2/3 receptor agonists. In PD, the daily dose of D2/3 receptor agonists correlated with the ordering-related subthalamic activation, which was not related to the accuracy cost. The findings suggest that damage to the SN may lead to sequential working memory deficits in PD, mediated by basal ganglia dysfunction.SIGNIFICANCELiu et al. demonstrate that damage to the substantia nigra (SN) correlates with basal ganglia dysfunction and poor sequencing performance in Parkinson's disease (PD). In neuromelanin-sensitive MRI, PD showed smaller SN than healthy controls. In a digit ordering task with functional MRI, PD's lower task accuracy was accompanied by the caudate and pallidal hypo-activation, subthalamic hyper-activation, and weakened functional connectivity between the SN and basal ganglia. PD with larger SN exhibited greater ordering-related caudate activation and lower ordering-related accuracy cost when sequencing digits. PD with more daily exposure to D2/3 receptor agonists exhibited greater ordering-related subthalamic activation, which did not reduce accuracy cost. It suggests that the SN may affect sequencing performance by regulating the task-dependent caudate activation in PD.
