Cerebral Hemodynamic Changes in Older Adults With Cognitive Complaints According to the Presence of Peripheral Artery Disease

AGING MEDICINE, EarlyView.
Among 132 older adults, 13 had peripheral artery disease (PAD), identified using the ankle–brachial index. Over approximately 13 months, PAD was associated with increasing middle cerebral artery mean flow velocity, with a significant difference in left‐sided velocity change between groups.

Transcranial focused ultrasound-induced blood‒brain barrier opening in mice without shaving hairs

Scientific Reports, 2023
Acoustic coupling through hairs remains a challenge to performing transcranial-focused ultrasound procedures. Here, we demonstrated that this challenge could be addressed by using oil as the coupling medium, leveraging oil's high affinity to hairs due to

Anodal Transcranial Direct Current Stimulation Improves Social Behavior Alongside Neuroplastic Changes in a Tsc2+/− Rat Model of Autism Spectrum Disorder

Autism Research, EarlyView.
ABSTRACT Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by altered synaptic connectivity and network organization, resulting in profound impairments in social communication and interaction. Transcranial direct current stimulation (tDCS) represents a promising approach to modulate maladaptive plasticity associated with ASD;

Low‐intensity focused ultrasound neuromodulation for drug‐resistant epilepsy: A randomized, sham‐controlled crossover trial

Epilepsia, EarlyView.
Abstract Objective This study was undertaken to evaluate the safety, feasibility, and efficacy of low‐intensity focused ultrasound (LIFU) as a noninvasive neuromodulation technique in patients with drug‐resistant epilepsy (DRE). Methods In this pilot, single‐blind, randomized sham‐controlled crossover trial, 12 patients with DRE underwent both LIFU and

Toward Inter‐Sonication Monitoring of Skull and Brain Temperatures in Transcranial MRgFUS Using a 3D Stack‐of‐Spirals Sequence

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop an MRI approach for simultaneous skull and brain temperature monitoring between sonications in transcranial MR‐guided focused ultrasound (MRgFUS) surgeries. Methods A 3D stack‐of‐spirals dual‐echo ultra‐short TE (UTE) sequence incorporating fat suppression, spiral deblurring, trajectory measurement, and B1 correction was ...

Transcranial Doppler ultrasound to assess cerebrovascular reactivity: reliability, reproducibility and effect of posture [PDF]

, 2013
Transcranial Doppler ultrasound (TCD) allows measurement of blood flow velocities in the intracranial vessels, and can be used to assess cerebral vasodilator responses to a hypercapnic stimulus. The reliability of this technique has not been established,

Muscle fatigue in patients with severe long COVID: A 2‐year follow‐up study

PM&R, EarlyView.
Abstract Background Fatigue is recognized as one of the most persistent and debilitating symptoms of long COVID, affecting both functionality and quality of life. However, its long‐term effects, especially beyond the first year after infection, remain poorly understood.
