Ten years of tracking mental health in refugee primary health care settings: an updated analysis of data from UNHCR's Health Information System (2009-2018).

BMC Med 2022 May 16;20(1):183. Epub 2022 May 16.

Public Health Section, Division of Resilience and Solutions, United Nations High Commissioner for Refugees, Geneva, Switzerland.

Background: This study examines mental, neurological, and substance use (MNS) service usage within refugee camp primary health care facilities in low- and middle-income countries (LMICs) by analyzing surveillance data from the United Nations High Commissioner for Refugees Health Information System (HIS). Such information is crucial for efforts to strengthen MNS services in primary health care settings for refugees in LMICs.

Department of Nuclear Medicine, Assistance Publique Hôpitaux de Marseille, Timone University Hospital, Marseille, France.

The relationship between post-traumatic stress disorder (PTSD) and focal epilepsy is poorly understood. It has been hypothesized that there is a complex and reciprocal potential reinforcement of the symptoms of each condition. In this study, we investigated whether there were PTSD-specific brain changes in temporal lobe epilepsy (TLE). Read More

Acute-onset amnesia: transient global amnesia and other causes.

Pract Neurol 2022 Jun 3;22(3):201-208. Epub 2022 May 3.

Department of Brain Sciences, Imperial College London, London, UK.

Acute-onset amnesia is a dramatic neurological presentation that can cause considerable concern to both patient and clinician. The patient typically presents with an inability not only to retain new memories but also to access previously acquired memories, suggesting disturbance of hippocampal function. Transient global amnesia (TGA) is the most common cause of acute-onset amnesia, and is characterised by a profound anterograde and retrograde amnesia that typically lasts for up to 24 hours.

Authors:
Debopam Samanta

Epilepsy Behav 2022 May 14;130:108678. Epub 2022 Apr 14.

Child Neurology Section, Department of Pediatrics, University of Arkansas for Medical Sciences, Little Rock, AR, United States. Electronic address:

DEPDC5-related epilepsy, caused by pathogenic germline variants(with or without additional somatic variants in the brain) of DEPDC5 (Dishevelled, Egl-10 and Pleckstrin domain-containing protein 5) gene, is a newly discovered predominantly focal epilepsy linked to enhanced mTORC1 pathway. DEPDC5-related epilepsy includes several familial epilepsy syndromes, including familial focal epilepsy with variable foci (FFEVF) and rare sporadic nonlesional focal epilepsy. DEPDC5 has been identified as one of the more common epilepsy genes linked to infantile spasms and sudden unexpected death (SUDEP). Read More

Neurology 2022 04 6;98(17):e1761-e1770. Epub 2022 Apr 6.

From the Department of Neurology (J.J.G., R.D.-A.), University of Pennsylvania, Philadelphia; University of Utah (E.K., S.P., D.F.T., A.R., M.J.P.), Salt Lake City, UT; University of Pittsburgh (A.C.V.C.), PA; University of Miami (M.R.L.), FL; and Yale University (H.A.), New Haven, CT.

Background And Objectives: Epilepsy is defined by the occurrence of multiple unprovoked seizures, but quality of life (QOL) in people with epilepsy is determined by multiple factors, in which psychiatric comorbid conditions play a pivotal role. Therefore, understanding the interplay between comorbid conditions and QOL across epilepsy phenotypes is an important step toward improved outcomes. Here, we report the impact of QOL across distinct epilepsy phenotypes in a cohort of post-9/11 veterans with high rates of traumatic brain injury (TBI). Read More

Immune Mechanism of Epileptogenesis and Related Therapeutic Strategies.

Biomedicines 2022 Mar 19;10(3). Epub 2022 Mar 19.

Epilepsy Unit, Regional University Hospital of Málaga, 29010 Málaga, Spain.

Immunologic and neuroinflammatory pathways have been found to play a major role in the pathogenesis of many neurological disorders such as epilepsy, proposing the use of novel therapeutic strategies. In the era of personalized medicine and in the face of the exhaustion of anti-seizure therapeutic resources, it is worth looking at the current or future possibilities that neuroimmunomodulator or anti-inflammatory therapy can offer us in the management of patients with epilepsy. For this reason, we performed a narrative review on the recent advances on the basic epileptogenic mechanisms related to the activation of immunity or neuroinflammation with special attention to current and future opportunities for novel treatments in epilepsy.

Post-Traumatic Epilepsy and Comorbidities: Advanced Models, Molecular Mechanisms, Biomarkers, and Novel Therapeutic Interventions.

Pharmacol Rev 2022 Apr;74(2):387-438

Department of Neuroscience and Experimental Therapeutics, College of Medicine, Texas A&M University Health Science Center, Bryan, Texas

Post-traumatic epilepsy (PTE) is one of the most devastating long-term, network consequences of traumatic brain injury (TBI). There is currently no approved treatment that can prevent onset of spontaneous seizures associated with brain injury, and many cases of PTE are refractory to antiseizure medications. Post-traumatic epileptogenesis is an enduring process by which a normal brain exhibits hypersynchronous excitability after a head injury incident. Read More

An Interplay Between Post-Traumatic Epilepsy and Associated Cognitive Decline: A Systematic Review.

Front Neurol 2022 24;13:827571. Epub 2022 Feb 24.

Neuropharmacology Research Strength, Jeffrey Cheah School of Medicine and Health Sciences, Monash University Malaysia, Subang Jaya, Malaysia.

Background: Post-traumatic epilepsy (PTE) is a devastating neurological outcome of traumatic brain injury (TBI), which may negatively impact the quality of life of patients with TBI, and may impose a huge socioeconomic burden. This burden may be due to long-term functional outcomes associated with PTE, particularly cognitive dysfunction. To date, the relationship between TBI and PTE remains unclear, with little known about how the effect of their link on cognitive function as well. Read More

Mild Traumatic Brain Injury-Induced Disruption of the Blood-Brain Barrier Triggers an Atypical Neuronal Response.

Front Cell Neurosci 2022 18;16:821885. Epub 2022 Feb 18.

Fralin Biomedical Research Institute, Virginia Tech Carilion, Roanoke, VA, United States.

Mild TBI (mTBI), which affects 75% of TBI survivors or more than 50 million people worldwide each year, can lead to consequences including sleep disturbances, cognitive impairment, mood swings, and post-traumatic epilepsy in a subset of patients. To interrupt the progression of these comorbidities, identifying early pathological events is key. Recent studies have shown that microbleeds, caused by mechanical impact, persist for months after mTBI and are correlated to worse mTBI outcomes. Read More

Brivaracetam prevents the development of epileptiform activity when administered early after cortical neurotrauma in rats.

Epilepsia 2022 Apr 17;63(4):992-1002. Epub 2022 Jan 17.

Departments of Physiology and Pharmacology, SUNY Downstate Health Sciences University, Brooklyn, New York, USA.

Objectives: There is no effective therapy to prevent the development of posttraumatic epilepsy (PTE). Recently, we reported that administration of the antiseizure medication (ASM) levetiracetam (LEV) shortly after trauma prevented the development of epileptiform activity in two experimental models of neurotrauma. However, the time window for effective intervention with LEV may be too narrow for most clinical settings. Read More
