Drugs 2022 May 21. Epub 2022 May 21.

Springer Nature, Private Bag 65901, Mairangi Bay, Auckland, 0754, New Zealand.

Ganaxolone (ZTALMY; Marinus Pharmaceuticals) is a synthetic neuroactive steroid that acts as a positive allosteric modulator of the gamma-aminobutyric acid (GABA) receptor complex. Ganaxolone received its first approval in March 2022 in the USA for the treatment of seizures associated with cyclin-dependent kinase-like 5 (CDKL5) deficiency disorder (CDD) in patients 2 years of age and older. Approval was based on the results of a multinational phase III trial, in which ganaxolone was effective in reducing seizure frequency in children and adolescents with CDD. Read More

Hum Brain Mapp 2022 May 20. Epub 2022 May 20.

Comprehensive Epilepsy Center, Department of Neurology, NYU Grossman School of Medicine, New York, New York, USA.

In-scanner head motion systematically reduces estimated regional gray matter volumes obtained from structural brain MRI. Here, we investigate how head motion affects structural covariance networks that are derived from regional gray matter volumetric estimates. We acquired motion-affected and low-motion whole brain T1-weighted MRI in 29 healthy adult subjects and estimated relative regional gray matter volumes using a voxel-based morphometry approach.

Semin Cardiothorac Vasc Anesth 2022 May 20:10892532221080946. Epub 2022 May 20.

University of Texas Health Science Center at Houston, Houston, TX, USA.

Mutations of the transport and Golgi organization 2 (TANGO2) genes are linked with both long-term neurological decline and acute metabolic crises during stress, leading to significant anesthetic risk. Crises are marked by rhabdomyolysis, lactic acidosis, seizures, cardiac dysfunction, and dysrhythmias. Much is unknown about optimal management of this condition, especially in the acute and critical care settings. Read More

Squamosal Suture Synostosis: An Under-Recognized Phenomenon.

Cleft Palate Craniofac J 2022 May 20:10556656221100675. Epub 2022 May 20.

6595University of Pittsburgh Medical Center, Pittsburgh, PA, USA.

Introduction: The squamosal suture (SQS) joins the temporal to the parietal bones bilaterally and is a poorly described site of craniosynostosis. SQS fusion is thought to occur as late as the fourth decade of life and beyond; however, we have incidentally noted its presence among our pediatric patients and hypothesize that it may occur earlier in life and more frequently than previously believed.

Methods: A retrospective review of imaging performed on pediatric patients was completed to identify patients with SQS synostosis. Read More

Presentation, Etiology, Outcome, and Differentiation of Visual Semiology of Adult Occipital Epilepsy From Visual Aura of Migraine Headache: A Prospective Study in a Tertiary Care Center in Bangladesh.

Cureus 2022 Apr 16;14(4):e24186. Epub 2022 Apr 16.

Neurology, Dhaka Medical College Hospital, Dhaka, BGD.

Background: Occipital epilepsy is an uncommon and likely underdiagnosed type of epilepsy that is often misdiagnosed as a migraine with aura. High clinical suspicion and subsequent electroencephalogram (EEG) and brain imaging lead to early diagnosis.  Methods: We recruited patients with occipital epilepsy based on visual semiology, structural abnormalities in the occipital region, or EEG changes who visited the Department of Neurology of Dhaka Medical College from June 2019 to January 2020.

Intra- and Inter-Subject Perspectives on the Detection of Focal Onset Motor Seizures in Epilepsy Patients.

Sensors (Basel) 2022 Apr 26;22(9). Epub 2022 Apr 26.

Epilepsy Center, Department of Neurosurgery, Medical Center-University of Freiburg, 79106 Freiburg im Breisgau, Germany.

Focal onset epileptic seizures are highly heterogeneous in their clinical manifestations, and a robust seizure detection across patient cohorts has to date not been achieved. Here, we assess and discuss the potential of supervised machine learning models for the detection of focal onset motor seizures by means of a wrist-worn wearable device, both in a personalized context as well as across patients. Wearable data were recorded in-hospital from patients with epilepsy at two epilepsy centers. Read More
