Background No previous studies have determined how the post-stroke integrity of non-corticospinal neural pathways relates to the efficacy of constraint-induced movement therapy (CIMT). Objectives We aimed to clarify the relationship between several non-corticospinal neural pathway integrities and the short- and long-term benefits of CIMT. Methods This was a pilot cohort study (UMIN registration number: R00027136UMIN000023566), for which we enrolled 13 patients with chronic stroke and hemiparesis who had undergone CIMT...

Studies that examined white matter (WM) alterations in amnestic mild cognitive impairment (aMCI) abound. This timely meta-analysis aims to synthesize the results of these studies. Seventy-seven studies (totalNaMCI=1844) were included. Fourteen region-of-interest-based (ROI-based) (k≥8;NaMCI≥284 per ROI) and two activation likelihood estimation (ALE) meta-analyses (fractional anisotropy [FA]: k=15;NaMCI=463; mean diffusivity [MD]: k=8;NaMCI=193) were carried out. Among the many significant ROI-related findings, reliable FA and MD alterations in the fornix, uncinate fasciculus, and parahippocampal cingulum were observed in aMCI...

INTRODUCTION AND HYPOTHESIS: Uterine preservation in uterine prolapse is an option for young patients. We hypothesized that sacrospinous hysteropexy (SSH) with anchorage to both the anterior and posterior cervix (SSH-ap) would have a better outcome than SSH with anchorage to the posterior cervix only (SSH-p). METHODS: This was a retrospective study including 75 patients who underwent SSH at Chang Gung Memorial Hospital between March 2008 and August 2013. Five were excluded due to incomplete data...

This review brings together current knowledge from tract tracing studies to update and reconsider those limbic connections initially highlighted by Papez (1937) for their presumed role in emotion. These connections link hippocampal and parahippocampal regions with the mammillary bodies, the anterior thalamic nuclei, and the cingulate gyrus, all structures now strongly implicated in memory functions. An additional goal of this review is to describe the routes taken by the various connections within this network...

Trigeminal neuralgia (TN) is a severe chronic neuropathic facial pain disorder. Affect-related behavioral and structural brain changes have been noted across chronic pain disorders, but have not been well-studied in TN. We examined the potential impact of TN (37 patients: 23 with right-sided TN, 14 with left-sided TN), compared to age- and sex-matched healthy controls, on three major white matter tracts responsible for carrying affect-related signals-i.e., cingulum, fornix, and medial forebrain bundle. Diffusion magnetic resonance imaging (dMRI), deterministic multi-tensor tractography for tract modeling, and a model-driven region-of-interest approach was used...

BACKGROUND: Thalamic deep brain stimulation (DBS) is an effective strategy for treatment of essential tremor (ET). With limitations of imaging modalities, targeting largely relies on indirect methods. This study was designed to determine the optimal target for DBS in ET and construct a targeting method based on probabilistic maps. METHODS: Patients with ET who had sustained tremor reduction at 1 year and optimal microelectrode recordings were selected. Stimulation volume was individually modeled in standard space, and a final optimal region was derived for the whole population...

Pure amnesia (amnesic syndrome) is an organic brain syndrome characterized by impairment in episodic memory, with either an anterograde or sometimes retrograde loss of memories. Although episodic memory is impaired, semantic memory, immediate memory, and procedural memory are preserved. The Papez circuit is a network of nerve fibers and nerve centers that starts and ends in the hippocampus travelling by way of the fornix, mammillary bodies, anterior thalamic nuclei, cingulate gyrus, and parahippocampal gyrus...

Diffusion tensor imaging (DTI) studies have detected white matter microstructural changes in essential tremor (ET). However, it is still unclear whether these changes are related to cognitive deficits, which have been described in ET patients. DTI-derived fractional anisotropy, mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity measures were compared between 23 ET patients and 23 age-, gender-, and education-matched healthy individuals, using whole-brain tract-based spatial statistics. Correlations of white matter changes with scores obtained from a detailed neuropsychological assessment were subsequently examined...
