Impact of Pediatric Posterior Fossa Tumor Treatments on Working Memory Tracts Using Resting‐State fMRI and Tractography

by Clinical Neuropsychologist | Friday, January 10, 2025 | Neuroimaging

ABSTRACT Background and Purpose Working memory, a primary cognitive domain, is often impaired in pediatric brain tumor survivors, affecting their attention and processing speed. This study investigated the long-term effects of treatments, including surgery,...

Brain MRI Detection of an Abnormal Peak Width of Skeletonized Mean Diffusivity in REM Sleep Behavior Disorder

by Clinical Neuropsychologist | Thursday, January 9, 2025 | Neuroimaging

ABSTRACT Background and Purpose Peak width of skeletonized mean diffusivity (PSMD) is a novel marker of white matter damage, which may be related to small vessel disease. This study aimed to investigate the presence of white matter damage in patients with isolated...

Role and Prognostic Implications of Venous Outflow Assessment in Acute Ischemic Stroke

by Clinical Neuropsychologist | Thursday, January 9, 2025 | Neuroimaging

ABSTRACT Introduction The venous outflow profile (VOP) is a crucial yet often overlooked aspect affecting stroke outcomes. It plays a major role in the physiopathology of acute cerebral ischemia, as it accounts for both the upstream arterial collaterals and cerebral...

Middle Cerebral Artery M2 Occlusions: Impact of Segment Dominance and Benefit of Direct Aspiration for the First‐Pass Effect

by Clinical Neuropsychologist | Monday, January 6, 2025 | Neuroimaging

ABSTRACT Background and Purpose Endovascular thrombectomy (EVT) for acute ischemic stroke (AIS) with M2 segment occlusion of the middle cerebral artery (MCA) is debatable. This study assessed the efficacy, safety, and functional outcomes of EVT in M2 occlusion...

Functional Connectivity to the Amygdala in the Neonate Is Impacted by the Maternal Anxiety Level During Pregnancy

by Clinical Neuropsychologist | Monday, January 6, 2025 | Neuroimaging

ABSTRACT Background and Purpose Anxiety during pregnancy is common, and exposure to heightened anxiety during pregnancy may influence children’s brain development and functioning. However, it is unclear if exposure to low levels of anxiety in utero would also...

Real‐Time 2D Phase‐Contrast MRI to Assess Cardiac‐ and Respiratory‐Driven CSF Movement in Normal Pressure Hydrocephalus

by Clinical Neuropsychologist | Tuesday, December 31, 2024 | Neuroimaging

ABSTRACT Background and Purpose In idiopathic normal pressure hydrocephalus (iNPH) patients, cerebrospinal fluid (CSF) flow is typically evaluated with a cardiac-gated two-dimensional (2D) phase-contrast (PC) MRI through the cerebral aqueduct. This approach is limited...
