Migraine: Epidemiology, Risk Factors, Pathophysiology, and Treatment

MedComm, Volume 7, Issue 9, September 2026.
Migraine is a highly prevalent, female‐predominant, and disabling brain disorder shaped by genetic susceptibility, hormonal influences, modifiable attack factors, and comorbidity‐related progression. This review integrates current evidence on migraine epidemiology, phase‐specific neurovascular and neuroglial mechanisms, including CGRP signaling and ...

Neurocardiology: Brain–Heart Interactions in the Heart

MedComm, Volume 7, Issue 9, September 2026.
The heart and brain maintain systemic homeostasis through bidirectional communication involving neural, biochemical, and mechanical pathways. Dysregulation of these pathways contributes to a spectrum of conditions involving heart–brain interactions, including Takotsubo syndrome, the epileptic heart, stroke–heart syndrome, heart failure, cardiac ...

Pattern of sensory processing disorder in school‐aged preterm children with attention‐deficit hyperactivity disorder

Psychiatry and Clinical Neurosciences Reports, Volume 5, Issue 3, September 2026.
Preterm children show high attention‐deficit/hyperactivity disorder (ADHD) prevalence and frequent sensory processing alterations. ADHD is associated with more severe impairments, particularly in sensory sensitivity, auditory processing, and behavioral domains.

Biogenic Silver Nanoparticles Mediated by Phytoconstituents of the Edible Spice Pimpinella anisum: Characterization and In Vitro, In Vivo, and In Silico Biological Evaluation

Journal of Food Science, Volume 91, Issue 9, September 2026.
ABSTRACT This study evaluated the aqueous extract of Pimpinella anisum seeds (AE‐PAS) and its green‐synthesized silver nanoparticles (PA‐AgNPs) using integrated in vitro, in vivo, and in silico approaches. LC–MS analysis identified 26 phytoconstituents, mainly sinapic acid (15.78%), hispidulin (15.35%), caffeic acid (11.09%), and rutin (8.86%).

Multi‐decadal woodland recovery after land abandonment: environmental constraints on passive rewilding in Mediterranean landscapes

Restoration Ecology, Volume 34, Issue 7, September 2026.
Abstract Introduction Across the Mediterranean Basin, land abandonment has opened large areas to passive rewilding, raising questions about the pace and variability of secondary succession in these landscapes and how ecological and abiotic gradients mediate vegetation recovery in post‐agricultural landscapes. Objectives This study aims to quantify long‐

BOLD fMRI activations and LC contrast associated with successful episodic memory in healthy older adults and MCI

Alzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION We examined whether locus coeruleus (LC) contrast, an indirect proxy for neuronal density and structural health, was related to delayed episodic memory in healthy older adults (OAs) and those with mild cognitive impairment (MCI) and its association with encoding‐related brain activity, controlling for emotional salience.
