Intraindividual Optic Nerve Sheath Variation and Intracranial Pressure Changes: A Systematic Review and Meta‐Analysis

by Clinical Neuropsychologist | Monday, September 8, 2025 | Neuroimaging

ABSTRACT Background and Purpose To review the existing evidence on multiple timepoint assessments of optic nerve sheath diameter (ONSD) as an indicator of intraindividual variation of intracranial pressure (ICP). Methods A systematic search identified studies...

Impact of Childhood Neighborhood Deprivation on White Matter and Functional Connectivity During Adolescence

by Clinical Neuropsychologist | Monday, September 8, 2025 | Neuroimaging

ABSTRACT Background and Purpose Socioeconomic determinants of health impact childhood development and adult health outcomes. One key aspect is the physical environment and neighborhood where children live and grow. Emerging evidence suggests that neighborhood...

Reliability and Spatial Consistency of MR Diffusion Tensor Imaging Measures Along the Cerebral Perivascular Space

by Clinical Neuropsychologist | Thursday, September 4, 2025 | Neuroimaging

ABSTRACT Background and Purpose Diffusion tensor imaging analysis along the perivascular space (DTI-ALPS) has emerged as a promising noninvasive method for evaluating water motion that may reflect glymphatic system function. However, the reliability of DTI-ALPS...

High Multiband Acceleration Degrades Resting‐State Functional MRI Reliability and Signal Quality Under Anesthesia

by Clinical Neuropsychologist | Saturday, August 23, 2025 | Neuroimaging

ABSTRACT Background and Purpose Resting-state fMRI (rs-fMRI) is increasingly used to map brain networks in patients under anesthesia, but technical factors can affect its utility. We evaluated the effects of sevoflurane, multiband acceleration, and scan duration on...

Atypical Edema in Posterior Reversible Encephalopathy Syndrome: Clinical Associations and Outcome

by Clinical Neuropsychologist | Monday, August 18, 2025 | Neuroimaging

ABSTRACT Background and Purpose Posterior reversible encephalopathy syndrome (PRES) is a neurotoxic state with characteristic imaging findings. While classic PRES typically involves parieto-occipital edema, atypical cases present with variable involvement of deep gray...

Advances in Collateral Neuroimaging for Acute Ischemic Stroke: Redefining Time and Tissue Windows in the Reperfusion Era

by Clinical Neuropsychologist | Monday, August 18, 2025 | Neuroimaging

ABSTRACT Cerebral collateral circulation is a critical determinant of infarct evolution, therapeutic response, and clinical outcomes in patients with acute ischemic stroke. While the concept of “time is brain” has traditionally guided reperfusion therapy, recent...
