Background: Bilateral cerebral peduncular infarction (BCPI) is an extremely rare neurological disorder, and related literature is scarce. This study investigated the clinical manifestations, magnetic resonance imaging (MRI) features and prognosis of BCPI.
Method: We retrospectively reviewed the clinical features, MRI and magnetic resonance angiography manifestations, and prognosis of 14 patients with BCPI, confirmed by diffusion-weighted MRI from 5050 cerebral infarction patients at our medical center from January 2007 to June 2013.
Result: Eleven of the 14 (78.6%) patients had quadriplegia and 9 (64.3%) had decreased consciousness. At the most severe stage, the National Institutes of Health Stroke Scale scores ranged from grades 4 to 26 (mean grade, 18.9). Eleven (78.6%) cases were caused by large artery atherosclerosis. Besides the bilateral cerebral peduncle, the pons (85.7%) and cerebellum (42.9%) were the other infarct locations. Twelve (85.7%) patients had vertebrobasilar artery occlusion or severe stenosis, and 12 (85.7%) did not have collateral patency of the posterior cerebral artery. Thirteen (92.9%) patients had poor prognosis and 9 of them died.
Occlusion: BCPI is a very rare disorder and associated with severe vertebrobasilar artery stenosis or occlusion without collateral patency of the posterior communicating artery. It has a very poor prognosis.

Objective: Focused ultrasound (FUS)-mediated blood-brain barrier (BBB) opening is safe and potentially beneficial in patients with Alzheimer's disease (AD) for the removal of amyloid-beta (Aβ) plaques. However, the optimal BBB opening intervals and number of treatment sessions for clinical improvement remain undefined. Therefore, the aim of this study was to evaluate the safety and benefits of repeated and more extensive BBB opening alone.

Electroencephalogram (EEG) monitoring during electroconvulsive therapy (ECT) is commonly done using a 2-channel EEG in order to capture activity from both brain hemispheres, though many institutions may instead opt to utilize a 1-channel EEG, often for reasons of convenience. We present a novel case of asymmetric termination of EEG seizure activity during an acute course of right unilateral ECT, prompting a full neurological workup to investigate potential underlying structural or physiological causative factors. This case assists in informing the necessity of bilateral hemispheric EEG monitoring as well as highlights the importance of searching for undiagnosed or latent neurological dysfunction in certain clinical situations arising during ECT.

Background: White matter hyperintensities (WMH) are prominent neuroimaging markers of cerebral small vessel disease (CSVD) linked to cognitive decline. Nevertheless, the pathophysiological mechanisms underlying WMH remain unclear.
Objective: This study aimed to assess the structural decoupling index (SDI) as a novel metric for quantifying the brain's hierarchical organization associated with WMH in cognitively normal older adults
Methods: We analyzed data from 112 cognitively normal individuals with varying WMH burdens (43 high WMH burden and 69 low WMH burden).

Background: Addiction affects millions of people, often resulting from a complex interplay between genetic and environmental factors, and is frequently linked to mental health disorders. Many experts agree there is no cure for addiction, but there are effective treatments available. Many patients continue to succumb to addiction despite treatment.
