Neuroprotective effect of Geijigadaehwang-tang against trimethyltin-induced hippocampal neurodegeneration: An in vitro and in vivo study.

J Ethnopharmacol 2022 Jun 17:115451. Epub 2022 Jun 17.

Department of Oriental Medicine, College of Oriental Medicine, Dongshin University, 120-9, Dongsindae-gil, Naju-si, Jeollanam-do, 58245, Republic of Korea. Electronic address:

Ethnopharmacological Relevance: Patients with dementia are diagnosed with deficiency patterns and interior patterns in traditional Chinese medicine due to decreased physical strength, mental atrophy including cognitive function, and decreased motor function in the gastrointestinal tract. Since "greater yin symptom" in Shanghanlun has been interpreted as interior, deficiency, and cold pattern in traditional Chinese medicine, it is necessary to determine whether Geijigadaehwang-tang (GDT) has therapeutic effects on neurodegenerative diseases and the underlying mechanism if it has such effects.

Aims Of The Study: Trimethyltin (TMT), a neurotoxic organotin compound, has been used to induce several neurodegenerative diseases, including epilepsy and Alzheimer's disease. Read More

A peptide blocking the ADORA1-neurabin interaction is anticonvulsant and inhibits epilepsy in an Alzheimer's model.

JCI Insight 2022 Jun 8;7(11). Epub 2022 Jun 8.

Departments of Cell, Developmental and Integrative Biology.

Epileptic seizures are common sequelae of stroke, acute brain injury, and chronic neurodegenerative diseases, including Alzheimer's disease (AD), and cannot be effectively controlled in approximately 40% of patients, necessitating the development of novel therapeutic agents. Activation of the A1 receptor (A1R) by endogenous adenosine is an intrinsic mechanism to self-terminate seizures and protect neurons from excitotoxicity. However, targeting A1R for neurological disorders has been hindered by side effects associated with its broad expression outside the nervous system. Read More

Sulphonylurea for Improving Neurological Features in Neonatal Diabetes: a systematic review and meta-analyses.

Pediatr Diabetes 2022 Jun 3. Epub 2022 Jun 3.

Pediatric Endocrinology, Gynaecology and Diabetology, Centre de Référence des Pathologies Gynécologiques Rares et des Maladies Endocriniennes Rares de la Croissance et du Développement, Hôpital Universitaire Necker Enfants Malades, Université de Paris, Paris, France.

Background: In monogenic diabetes due to KCNJ11 and ABCC8 mutations that impair KATP- channel function, sulphonylureas improve long-term glycaemic control. Although KATP channels are extensively expressed in the brain, the effect of sulphonylureas on neurological function has varied widely. We evaluated published evidence about potential effects of sulphonylureas on neurological features, especially epilepsy, cognition, motor function and muscular tone, visuo-motor integration, and attention deficits in children and adults with KCNJ11 and ABCC8-related neonatal-onset diabetes mellitus.

Functional correlates of clinical phenotype and severity in recurrent SCN2A variants.

Commun Biol 2022 05 30;5(1):515. Epub 2022 May 30.

Ion Channels and Human Diseases Group, The Florey Institute of Neuroscience and Mental Health, University of Melbourne, Parkville, VIC, 3052, Australia.

In SCN2A-related disorders, there is an urgent demand to establish efficient methods for determining the gain- (GoF) or loss-of-function (LoF) character of variants, to identify suitable candidates for precision therapies. Here we classify clinical phenotypes of 179 individuals with 38 recurrent SCN2A variants as early-infantile or later-onset epilepsy, or intellectual disability/autism spectrum disorder (ID/ASD) and assess the functional impact of 13 variants using dynamic action potential clamp (DAPC) and voltage clamp. Results show that 36/38 variants are associated with only one phenotypic group (30 early-infantile, 5 later-onset, 1 ID/ASD). Read More

Henri Legrand du Saulle's 1873 book: "La Folie Héréditaire" (hereditary madness).

Am J Med Genet B Neuropsychiatr Genet 2022 Apr 23;189(3-4):51-59. Epub 2022 May 23.

Department of Psychiatry, Virginia Institute of Psychiatric and Behavioral Genetics, Medical College of Virginia/Virginia Commonwealth University, Richmond, Virginia, USA.

In his 1873 monograph "La Folie Héréditaire," the French Alienist Legrand du Saulle (LdS) first outlined his understanding of hereditary factors in insanity and then described in detail the theory of Hereditary Madness (HM) that emerged from the writings of his mentor Bénédict Morel. This form of insanity was thought to arise only in families with neuropathic traits. Degeneration theory, proposed by Morel, postulated a within-family "evolution" of increasingly severe psychopathology, typically beginning with mild neuropathic traits and associated idiosyncrasies, and progressing over generations to hereditary madness, mental retardation, epilepsy, and eventual sterility.

Role of the pathologist in the diagnosis of autoimmune encephalitis.

Indian J Pathol Microbiol 2022 May;65(Supplement):S198-S206

Department of Neuropathology, National Institute of Mental Health and Neurosciences, Bengaluru, Karnataka, India.

Autoimmune encephalitis is a group of non-infectious immune-mediated inflammatory disorders manifesting with epilepsy and encephalitis syndromes that are associated with autoantibodies in the serum and/or cerebrospinal fluid (CSF). Pathogenic autoantibodies have been discovered against intracellular onconeural antigens, surface neuronal, or synaptic antigens with distinctive pathogenesis that underlie differences in response to immunotherapy. The onconeural antigens incite cytotoxic T-cell-mediated neuronal destruction, whereas surface antigens trigger direct damage by autoantibodies via complement mediated pathways, and hence respond well to immunomodulatory therapy, in contrast to poor response in the former.
