Neurobiological Mechanisms Underlying Psychological Dysfunction After Brain Injuries.

Despite the presentation of similar psychological symptoms, psychological dysfunction secondary to brain injury exhibits markedly lower treatment efficacy compared to injury-independent psychological dysfunction. This gap remains evident, despite extensive research efforts. This review integrates clinical and preclinical evidence to provide a comprehensive overview of the neurobiological mechanisms underlying neuropsychological disorders, focusing on the role of key brain regions in emotional regulation across various forms of brain injuries.

Molecular Biomarkers Associated with Traumatic Brain Injury Outcome in Individuals of Black Racial Identity or African Ancestry: A Narrative Review.

Traumatic brain injury (TBI) is a leading cause of death and disability worldwide and a major global health concern. In the United States, individuals of Black or African American racial identity experience disproportionately higher rates of TBI and suffer from worse postinjury outcomes. Contemporary research agendas have largely overlooked or excluded Black populations, resulting in the continued marginalization of Black patient populations in TBI studies, thereby limiting the generalizability of ongoing research to patients in the United States and around the world.

Neurosurgery in Pakistan: Past, Present, and Future.

Background And Objectives: Since its independence from India in 1947, Pakistan has struggled with economic crises such as global debt, corruption, constant regime change, and a decades-long war against terrorism. The resulting socioeconomic barriers have stymied efforts to develop a comprehensive and equitably accessible healthcare system, especially regarding safe, timely, and affordable surgical care. This article evaluates neurosurgery's development, current state, and prospects in Pakistan, a lower-middle-income country.

Bimodal functions of calcitonin gene-related peptide in the brain.

Aims: Calcitonin gene-related peptide (CGRP) is a pluripotent neuropeptide crucial for maintaining vascular homeostasis, yet its full therapeutic potential remains incompletely exploited. Within the brain, CGRP demonstrates a distinct bimodal effect, contributing to neuroprotection in ischemic conditions while inducing neuronal sensitization and inflammation in non-ischemic settings. Despite extensive research on CGRP, the absence of a definitive determinant for this observed dichotomy has limited its potential for therapeutic applications in the brain.

CGRP as a potential mediator for the sexually dimorphic responses to traumatic brain injury.

Background: The outcomes of traumatic brain injury (TBI) exhibit variance contingent upon biological sex. Although female sex hormones exert neuroprotective effects, the administration of estrogen and progesterone has not yielded conclusive results. Hence, it is conceivable that additional mediators, distinct from female sex hormones, merit consideration due to their potential differential impact on TBI outcomes.
