Article Abstract
Background: Cranial nerve palsy (CNP) in patients with intracranial aneurysms (IAs) can impose significant burdens on a patient's quality of life. The literature has a paucity of reviews addressing patterns of overall reported cranial nerve (CN) involvement and outcomes in patients with IA.
Methods: The literature systematically reviewed CNP at presentation in the setting of IA using PubMed, Web-of-Science, and Scopus according to the PRISMA guidelines.
Results: Fifty-two studies reported a total of 513 patients with IA and 630 CNPs observed at presentation: oculomotor (58.25%), abducent (15.87%), optic (12.06%), trochlear (8.7%), and trigeminal (1.9%). Most common aneurysms are located in a posterior communicating artery (46%) and cavernous internal carotid artery (29.2%). Trends of CNP based on the rupture status of IAs showed that 80% were associated with unruptured IAs and 20% with ruptured IAs. Post-treatment of IA, 55% of patients had complete resolution of CNP, with most (89%; = 134) resolving within the first 6 months. Stratified by CNP type: Complete resolution rate is 100% in CN VII-IX, 60% in CN VI, 59% in CN IV, 54% in CN III, 45% in CN V, and 43% in CN II.
Conclusion: In patients with cranial nerve palsies attributed to IAs, the location and rupture status of the aneurysm could determine the type and severity of the nerve palsy. Most patients experienced favorable outcomes in terms of their resolution and long-term function of the CNP after treatment of the IA.

Resting vagal tone, alpha amylase and cortisol levels in women with eating disorders before and after psychotherapy.
PLoS One
September 2025
Faculty of Psychology, Mental Health Research and Treatment Center, Ruhr University Bochum, Bochum, Germany.
Background: Eating disorders such as Anorexia Nervosa (AN) and Bulimia Nervosa (BN) were previously found to partly entail alterations in stress physiology including salivary cortisol (sC), and salivary alpha amylase (sAA) at rest and basal vagal tone (HF-HRV), compared to individuals without mental disorders or with mixed mental disorders (anxiety and depressive disorders), but corresponding data remain scarce and are not entirely consistent.
Method: HF-HRV, sC and sAA at rest were assessed in a female sample of 58 individuals with AN and 54 individuals with BN before and after psychotherapy and contrasted against measurements from 59 female individuals suffering from mixed disorders and 101female healthy controls.
Results: Values for sC were elevated in AN compared to all other groups, those for HF-HRV were highest in both AN and BN and lowest in mixed mental disorders and no differences were found at rest for sAA.
Variations in Presentation of Basilar Dolichoectasia: A Case Series.

Neurology, University of Texas Medical Branch, Galveston, USA.
Vertebrobasilar dolichoectasia (VBD) is a vascular anomaly marked by abnormal elongation and dilation of the vertebral and basilar arteries. Often, VBD remains undiagnosed or is discovered incidentally during evaluations of vascular events such as ischemia, hemorrhage, hydrocephalus, or cranial nerve palsies. While most patients are managed conservatively, treatment choices are highly individualized based on clinical presentation, vessel characteristics, and risk factors.

August 2025
Medical Education Division, Weill Cornell Medicine - Qatar, Doha, Qatar.
Purpose: Neuroanatomy is a cornerstone of medical education, yet its complexity often leads to student apprehension, termed "neurophobia." This quantitative study evaluated the effectiveness of online Functional Neuroanatomy modules in enhancing second-year medical students' understanding of neuroanatomy at Weill Cornell Medicine-Qatar during the 2024-25 academic year.
Participants And Methods: Four functional neuroanatomy modules were developed: Brainstem Anatomy, Sensory Pathway, Motor Pathway, and Cranial Nerves.
Intraindividual Optic Nerve Sheath Variation and Intracranial Pressure Changes: A Systematic Review and Meta-Analysis.
J Neuroimaging
September 2025
Faculdade de Medicina, Universidade de Lisboa, Lisbon, Portugal.
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 assessing intraindividual variation in ICP through multiple timepoint measurements of ONSD using ultrasonography. Meta-analysis of studies assessing intraindividual correlation coefficients between ONSD and ICP was performed using a random effects model, and we calculated the weighted correlation coefficient for the expected change in ICP associated with variations in ONSD.

Guillain-Barré Syndrome (GBS) is an acute immune-mediated inflammatory demyelinating polyradiculopathy of the peripheral nerves often provoked by a preceding upper respiratory or gastrointestinal infection. Guillain-Barré Syndrome usually presents with symmetrical lower limb ascending weakness and decreased deep tendon reflexes. Here, we describe a case of an uncommon presentation of GBS presenting with upper extremity neuropathy and cranial nerve palsy in a 36-year-old Caucasian Army pilot.
