Social network size and mental health outcomes in youth with neuroinflammatory disorders.

Background: 75 % of youth with MS report symptoms of fatigue, depression, and anxiety. Social network size (number of people in an individual's network) is known to have positive impacts on health and health behavior in pediatric populations and in individuals with multiple sclerosis.

Objectives: To estimate associations between social network size (SNS) and depression, anxiety, symptoms of post-traumatic stress disorder (PTSD), and quality of life among youth with recurrent neuroinflammatory disorders (RNI) in comparison to that of youth with monophasic acquired demyelinating syndrome (mono-ADS).

Antiepileptic Drugs as Potential Dementia Prophylactics Following Traumatic Brain Injury.

Seizures and other forms of neurovolatility are emerging as druggable prodromal mechanisms that link traumatic brain injury (TBI) to the progression of later dementias. TBI neurotrauma has both acute and long-term impacts on health, and TBI is a leading risk factor for dementias, including chronic traumatic encephalopathy and Alzheimer's disease. Treatment of TBI already considers acute management of posttraumatic seizures and epilepsy, and impressive efforts have optimized regimens of antiepileptic drugs (AEDs) toward that goal.

[Recent developments in the modeling and psychological management of persecutory ideation].

Persecutory ideas are a major clinical problem and are associated with impaired functioning, reduced compliance with medication and increased risk of hospitalization. Persecutory ideation is defined as the false conviction that others are threatening or conspiring against one. Although persecutory delusions are mainly described and experienced in schizophrenia spectrum disorders, they also occur in other neurological and psychiatric diagnoses including Alzheimer disease, epilepsy, depression, mania, dementia and post-traumatic stress disorder.

Harriet Tubman's Hypersomnia: Insights from Historical and Medical Perspectives.

Harriet Tubman, a hero of the abolitionist movement and early civil rights advocate, suffered a head injury in childhood and subsequently developed sleep attacks associated with visions that were extensively documented in historical accounts. Her contemporaries perceived these visions together with unpredictable and unavoidable urges to sleep as manifestations of her deep faith, rather than as symptoms of an illness. While religious perspectives remain crucial to understanding Tubman's sleep-related experiences, some may consider them insufficient in view of modern medical advances.

A machine learning approach to seizure detection in a rat model of post-traumatic epilepsy.

Epilepsy is a common neurologic condition frequently investigated using rodent models, with seizures identified by electroencephalography (EEG). Given technological advances, large datasets of EEG are widespread and amenable to machine learning approaches for identification of seizures. While such approaches have been explored for human EEGs, machine learning approaches to identifying seizures in rodent EEG are limited.

Derailment of Sleep Homeostatic Plasticity Affects the Most Plastic Brain Systems and Carries the Risk of Epilepsy.

Although a critical link between non-rapid eye movement (NREM) sleep and epilepsy has long been suspected, the interconnecting mechanisms have remained obscure. However, recent advances in sleep research have provided some clues. Sleep homeostatic plasticity is now recognized as an engine of the synaptic economy and a feature of the brain's ability to adapt to changing demands.

Dispensary Staff Perceptions About the Benefits, Risks, and Safety of Cannabis for Medical Purposes.

Background: Therapeutic use of cannabis is common in the United States (up to 18.7% of Americans aged ≥12), and dispensaries in the US are proliferating rapidly. However, the efficacy profile of medical cannabis is unclear, and customers often rely on dispensary staff for purchasing decisions.

[Traumatic brain injury].

Traumatic brain injury (TBI) describes parenchymal brain damage caused by external forces to the head. It has a massive personal and socioeconomic impact, as it is a disease with high morbidity and mortality. Both young and old people are affected, as a result of traffic or sports accidents as well as due to falls at home.

Marchiafava-Bignami disease: Case presentation and radiological imaging.

Marchiafava-Bignami disease (MBD) is a rare vitamin B deficiency classically associated with alcoholism. MBD damages the corpus callosum and presents with nonspecific neurological symptoms. Radiological imaging is critical for diagnosing MBD and commencing subsequent treatment, which often consists of vitamin B supplementation.

Surgical Outcomes in Post-Traumatic Temporal Lobe Epilepsy: A Systematic Review and Meta-Analysis.

Epilepsy surgery provides excellent benefits in post-traumatic epilepsy of the temporal lobe (PTE-TL), but outcomes relative to non-traumatic epilepsy of the temporal lobe (NTE-TL) are less favorable. Large well-designed studies are recommended to further clarify the role of epilepsy surgery in PTE. It is unclear whether epilepsy surgery outcomes in PTE are as robust as described for drug resistant epilepsy (DRE) in general.

The Long-Term Use of Diagnostic Subdural Electroencephalogram Electrodes and Subdural Hematoma: A Prospective Cohort Study.

Objectives: Seizures and status epilepticus (SE) are frequent complications of acute subdural hematoma (aSDH) associated with increased morbidity and mortality. Therefore, we aimed to evaluate whether invasive subdural electroencephalogram recording leads to earlier seizure detection and treatment initiation in patients with aSDH.

Design: Prospective, single-center, cohort trial.

Post-traumatic stress disorder (PTSD), cognitive control, and perceived seizure control in patients with epilepsy: An exploratory study.

Epilepsy is often linked to various psychiatric symptoms, with anxiety, depression, and interictal dysphoric disorders being the most prevalent. Few studies have investigated posttraumatic stress disorder (PTSD) in epilepsy, but they suggest a notable prevalence of PTSD. PTSD is known to be associated with cognitive impairments, particularly memory and executive functions.

4-AP challenge reveals that early intervention with brivaracetam prevents posttraumatic epileptogenesis in rats.

Purpose: There are currently no clinical treatments to prevent posttraumatic epilepsy (PTE). Recently, our group has shown that administration of levetiracetam (LEV) or brivaracetam (BRV) shortly after cortical neurotrauma prevents the development of epileptiform activity in rats, as measured ex vivo in neocortical slices. Due to the low incidence of spontaneous seizures in rodent-based models of traumatic brain injury (TBI), chemoconvulsants have been used to test injured animals for seizure susceptibility.

A preliminary study of calcium channel-associated mRNA and miRNA networks in post-traumatic epileptic rats.

The calcium channels are the main pathogenesis and therapeutic target for post-traumatic epilepsy (PTE). However, differentially expressed miRNAs (DEMs) and mRNAs associated with calcium channels in PTE and their interactions are poorly understood. We produced a PTE model in rats and conducted RNA-seq in PTE rats.

Image data harmonization tools for the analysis of post-traumatic epilepsy development in preclinical multisite MRI studies.

Preclinical MRI studies have been utilized for the discovery of biomarkers that predict post-traumatic epilepsy (PTE). However, these single site studies often lack statistical power due to limited and homogeneous datasets. Therefore, multisite studies, such as the Epilepsy Bioinformatics Study for Antiepileptogenic Therapy (EpiBioS4Rx), are developed to create large, heterogeneous datasets that can lead to more statistically significant results.

Manual lesion segmentations for traumatic brain injury characterization.

Traumatic brain injury (TBI) often results in heterogenous lesions that can be visualized through various neuroimaging techniques, such as magnetic resonance imaging (MRI). However, injury burden varies greatly between patients and structural deformations often impact usability of available analytic algorithms. Therefore, it is difficult to segment lesions automatically and accurately in TBI cohorts.

The effects of strength of religious faith on post-traumatic growth in patients with epilepsy.

Aim: This study was conducted to examine the effects of strength of religious faith on post-traumatic growth in patients with epilepsy.

Method: This cross-sectional and correlational study was conducted with 112 participants who were admitted to the neurology outpatient clinic of a university hospital in eastern Turkey, who met the research criteria and agreed to participate in the study. The data were collected by using "Descriptive Information Form", "Santa Clara Strength of Religious Faith Questionnaire (SCSRFQ)", and "Post-traumatic Growth Inventory (PTGI)".

ECoG spiking activity and signal dimension are early predictive measures of epileptogenesis in a translational mouse model of traumatic brain injury.

The latency between traumatic brain injury (TBI) and the onset of epilepsy (PTE) represents an opportunity for counteracting epileptogenesis. Antiepileptogenesis trials are hampered by the lack of sensitive biomarkers that allow to enrich patient's population at-risk for PTE. We aimed to assess whether specific ECoG signals predict PTE in a clinically relevant mouse model with ∼60% epilepsy incidence.

Case report: "Proust phenomenon" after right posterior cerebral artery occlusion.

Odors evoking vivid and intensely felt autobiographical memories are known as the "Proust phenomenon," delineating the particularity of olfaction in being more effective with eliciting emotional memories than other sensory modalities. The phenomenon has been described extensively in healthy participants as well as in patients during pre-epilepsy surgery evaluation after focal stimulation of the amygdalae and post-traumatic stress disorder (PTSD). In this study, we provide the inaugural description of aversive odor-evoked autobiographical memories after stroke in the right hippocampal, parahippocampal, and thalamic nuclei.

Posttraumatic epilepsy in critically ill children with traumatic brain injury.

Purpose: The aim of this study was to determine the clinical, laboratory, and radiological factors related with posttraumatic epilepsy (PTE).

Methods: The study is a multicenter descriptive cross-sectional cohort study. Children who followed up for TBI in the pediatric intensive care unit between 2014 and 2021 were included.

Delayed treatment with ceftriaxone reverses the enhanced sensitivity of TBI mice to chemically-induced seizures.

The pathophysiological changes that occur after traumatic brain injury (TBI) can lead to the development of post-traumatic epilepsy, a life-long complication of brain trauma. The etiology of post-traumatic epilepsy remains unknown, but TBI brains exhibit an abnormal excitatory / inhibitory balance. In this study, we examine how brain injury alters susceptibility to chemically-induced seizures in C57Bl/6J mice, and if pharmacological enhancement of glutamate transporters can reduce chronic post-traumatic seizures.

Dissociation in patients with epilepsy and functional seizures: A narrative review of the literature.

Dissociation is a "disruption of the usually integrated functions of consciousness, memory, identity or perception of the environment" according to DSM-5.  It is commonly seen in psychiatric disorders including primary dissociative disorders, post-traumatic stress disorder, depression, and panic disorder. Dissociative phenomena are also described in the context of substance intoxication, sleep deprivation and medical illnesses including traumatic brain injury, migraines, and epilepsy.

Closed-loop brain stimulation augments fear extinction in male rats.

Dysregulated fear reactions can result from maladaptive processing of trauma-related memories. In post-traumatic stress disorder (PTSD) and other psychiatric disorders, dysfunctional extinction learning prevents discretization of trauma-related memory engrams and generalizes fear responses. Although PTSD may be viewed as a memory-based disorder, no approved treatments target pathological fear memory processing.
