Quantitative and Qualitative Differences of Action Verbal Fluency between Young and Older Adults

Soomin Kim et al.

Summary: This study investigates the age-related quantitative and qualitative differences in action verbal fluency (AVF) of Korean adults. The results show that the older group performs worse than the young group in AVF both quantitatively and qualitatively. The older group produces more simple verbs and fewer moment verbs in comparison.

Effects of Noninvasive Cervical Vagal Nerve Stimulation on Cognitive Performance But Not Brain Activation in Healthy Adults

Ruth Klaming et al.

Summary: This study aimed to assess the effects of noninvasive vagal nerve stimulation (nVNS) on complex visuospatial problem solving in healthy individuals. The results showed that participants who received nVNS performed better in terms of accuracy, reaction time, and error rate. These findings provide initial support for nVNS as a low-risk, low-cost treatment for cognitive disorders.

Reduced cerebral blood flow of lingual gyrus associated with both cognitive impairment and gait disturbance in patients with idiopathic normal pressure hydrocephalus

Yuya Suzuki et al.

Summary: Patients with iNPH have severely impaired cognitive function, but motor dysfunction of the legs is similar to PD patients. The cognitive and gait disturbances of iNPH are significantly interrelated, which may be associated with an impaired brain network that includes the bilateral lingual gyrus.

Characteristics of the Fractional Amplitude of Low-Frequency Fluctuation in Ocular Hypertension Patients: A Resting-State fMRI Study

Ying Liang et al.

Summary: This study investigated the nature of spontaneous brain activity in ocular hypertension (OH) patients and its relationship with clinical features using rs-fMRI and fALFF method. The results revealed that the fALFF values in two specific brain areas were associated with visual impairment in OH patients.

Advances in the Treatment of Cholinergic Anti-Inflammatory Pathways in Gastrointestinal Diseases by Electrical Stimulation of Vagus Nerve

Wei Lei et al.

Summary: The cholinergic anti-inflammatory pathway (CAIP) modulates the immune system through the vagus nerve (VN) and plays an anti-inflammatory role. The mechanism of the anti-inflammatory effect of VNS through CAIP is not fully known, but animal studies have shown beneficial effects in treating inflammatory diseases, particularly in the gastrointestinal tract.

Cervical transcutaneous vagal nerve stimulation (ctVNS) improves human cognitive performance under sleep deprivation stress

Lindsey K. McIntire et al.

Summary: The research evaluated the efficacy of non-invasive cervical transcutaneous vagal nerve stimulation (ctVNS) on mitigating the negative effects of fatigue on cognition and mood. Results suggest that ctVNS can significantly improve arousal and multi-tasking, and may represent an alternative treatment for fatigue in humans.

Cognitive Processes Underlying Verbal Fluency in Multiple Sclerosis

Alfonso Delgado-Alvarez et al.

Summary: Verbal fluency in Multiple Sclerosis is influenced by various cognitive processes, such as attention-executive functioning, memory, and language. Machine-learning algorithms using VF-derived scores can effectively predict cognitive deficits in MS patients, particularly in the areas of general cognitive impairment and executive dysfunction.

Temporal dynamic changes of intrinsic brain activity in Alzheimer's disease and mild cognitive impairment patients: a resting-state functional magnetic resonance imaging study

Ting Li et al.

Summary: This study explored dynamic brain activity in patients with Alzheimer's disease (AD) and mild cognitive impairment (MCI) using dALFF and dfALFF metrics, finding that AD patients showed increased dALFF variability in the cerebellar posterior and temporal lobes compared to healthy controls. These findings suggest a potential insight into the neurophysiological mechanisms of AD based on functional magnetic resonance imaging data.

Vagus nerve stimulation in brain diseases: Therapeutic applications and biological mechanisms

Yue Wang et al.

Summary: With the development of medical technology, vagus nerve stimulation (VNS) has been approved by the FDA as an alternative treatment for refractory epilepsy, refractory depression, cluster headaches, and migraines. Although VNS has shown promising results for more brain diseases like Parkinson's disease, autistic spectrum disorder, and traumatic brain injury, the specific biological mechanisms underlying its beneficial effects remain incompletely understood.

Noninvasive Cervical Vagal Nerve Stimulation Alters Brain Activity During Traumatic Stress in Individuals With Posttraumatic Stress Disorder

Matthew T. Wittbrodt et al.

Summary: The study confirmed that transcutaneous cervical vagal nerve stimulation (tcVNS) can increase brain activations in specific regions during trauma scripts, potentially indicating a reversal of neurobiological changes in patients with posttraumatic stress disorder (PTSD).

Cognitive and Behavioral Disorders in Patients with Precuneal Infarcts

Emre Kumral et al.

Summary: This study evaluated the clinical, neurocognitive, and behavioral characteristics of patients with isolated PC infarcts and found that damage within different regions of the precuneal cortex can lead to various types of cognitive disorders. Predominant cognitive impairments include visuospatial disorders and self-processing impairment in patients with precuneal infarcts.

Considerations for using the Wisconsin Card Sorting Test to assess cognitive flexibility

Stephanie Miles et al.

Summary: This critical review examines the changes in the WCST, differences in existing scoring methods, key terminology and its relation to cognitive flexibility assessment, and issues with the use of WCST in the literature. It particularly focuses on the confusion between 'perseverative responses' and 'perseverative errors' and the inconsistencies in scoring these variables, providing recommendations for future research and clinical practice using the WCST.
