Background: Thalamic hemorrhage constitutes 6% to 25% of intracerebral hemorrhages. Vascular lesions affecting the thalamus may cause a variety of clinical symptoms. This retrospective study aims to evaluate localization of hemorrhage and clinical symptoms in patients with thalamic hemorrhage.
Methods: One hundred and one patients with thalamic hemorrhage were examined retrospectively in our department. Hemorrhages were classified into 5 groups according to computed tomography: medial (thalamoperforate), anterolateral (tuberothalamic), posterolateral (thalamogeniculate), dorsal (posterior choroidal), and global. The relation between volume, localization, and penetration to adjacent structures/ventricles of hemorrhage and risk factors, clinical features, and prognosis were evaluated.
Results: The study group included 101 patients. Eighty-two percent of the patients had hypertension, 19.8% had diabetes mellitus, 14.9% had cardiac disease, and 5.9% had chronic renal failure. Mean blood pressure was 173/101 mm Hg. Decreased Glasgow coma scale was significantly higher in the global hemorrhage group than in all regional groups (Chi-square, 10.54; P = .002). Medial group hemorrhages had a significantly higher rate than anterolateral, posterolateral, and dorsal intraventricular expansion. Out of speech disorders, 49% of patients had a right thalamic lesion (especially dysarthria) and 51% of patients had a left thalamic lesion (mostly aphasia).
Conclusions: In the study, we detected that the most important risk factor in thalamic hemorrhage is hypertension. The prognosis is worse in global and medial group hemorrhages, especially those which rupture to the ventricle, than the other groups. Thalamic lesions cause a variety of symptoms, including forms of aphasia, such as crossed dextral aphasia.

Unlabelled: To analyze the clinical characteristics of an overlapping syndrome, MNOS, of anti-myelin oligodendrocyte glycoprotein antibody (MOG-Ab) coexisting with anti-N-methyl-D-aspartate receptor encephalitis (NMDARE) in children. We included patients with NMDARE at Children's Hospital of Chongqing Medical University between 2018 and 2022 and conducted a comparison between NMDARE with and without MOG-Ab. Among 163 patients with NMDARE, 15 individuals tested positive for MOG-Ab.

A patient in their early 60s presented with a headache and right-sided numbness. Imaging revealed a hemorrhagic lesion in the left thalamus and venous engorgement involving the left sphenoparietal sinus, with drainage through the basal vein of Rosenthal and the superficial middle cerebral vein. The trans-Galen approach was utilized for embolization, successfully obliterating the fistulas using coils without retrograde opacification.

Background: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most common hereditary cerebral small vessel disease (CSVD). Intracerebral hemorrhage (ICH) is reported to be increasing in CADASIL patients from areas where the p.R544C mutation is prevalent (e.

Background: Aberrant interoceptive processing has been hypothesized to contribute to the pathophysiology of functional neurological disorder, although findings have been inconsistent. Here, we utilized functional magnetic resonance imaging (fMRI) to examine neural correlates of interoceptive attention - the conscious focus and awareness of bodily sensations - in functional movement disorder (FMD).
Methods: We used voxelwise analyses to compare blood oxygenation level-dependent responses between 13 adults with hyperkinetic FMD and 13 healthy controls (HCs) during a task requiring attention to different bodily sensations and to an exteroceptive stimulus.
