Background: Although significantly increased mental health concerns were noted globally during the first year of the COVID-19 pandemic, much less is known about the mental health trends during the COVID-19 recovery period. We aimed to compare current anxiety or depression rates to those before and during the first year of the pandemic and to evaluate demographic differences. Methods: We analyzed Household Pulse Survey data prospectively collected from a representative U.S. population sample. We compared the anxiety or depression rates from the first pandemic year (04/2020–05/2021) and recovery period (06/2023–03/2024) from the national cohort and demographic subgroups using two-sided paired t-tests and regression analyses and compared these to pre-pandemic (01/2019–12/2019) rates using one-sided t-tests. Results: The national estimates for anxiety or depression improved during the recent COVID-19 recovery period as compared to the first year (29.5 ± 5.5 vs. 37.6 ± 3.1; p < 0.0001) but did not return to the pre-pandemic benchmark (29.5% vs. 10.8%; p < 0.001). Higher rates were noted in younger individuals aged 18–29 years (p < 0.0001), in individuals with less than a high school diploma (p < 0.0001), or with disabilities (p < 0.0001). Non-Hispanic Asians reported the lowest rates (p < 0.0001), and no significant gender differences were noted. Conclusion: The U.S. population’s mental health concerns have improved since the first year of the pandemic but remain above pre-pandemic benchmarks. Certain demographic subgroups are at higher risk, indicating the need for targeted health care and economic policy interventions to address these disparities.

Sturge–Weber Syndrome (SWS) is a rare neurocutaneous disorder caused by a somatic nonsynonymous mosaic mutation most commonly in the GNAQ gene (G protein guanine Nucleotide-binding protein Alpha subunit q). SWS is characterized by capillary-venous malformations in the brain and eyes and a characteristic facial port wine (PW) birthmark (previously called port wine stain/PWS) in the head/neck region. Clinical manifestations vary and include epilepsy, stroke-like episodes, migraine headaches, cognitive delays, glaucoma, ocular vascular anomalies, heterochromia of the iris, visual field defects, and endocrine disorders like growth hormone deficiency or central hypothyroidism. The pathognomonic findings seen in neuroimaging with magnetic resonance imaging (MRI) include the presence of unilateral intracranial leptomeningeal angiomatosis, typically ipsilateral to the facial birthmark. SWS does not currently have a definitive cure, and management strategies focus on symptomatic management such as anti-seizure medications, limited surgical resection of the epileptogenic tissue or hemispherectomy for cases of drug-resistant epilepsy (DRE), selective photo-thermolysis of the PWS using a pulsed dye laser, and the medical and/or surgical management of glaucoma. In addition to these symptomatic treatments, the use of preventive, modifying, or stabilizing treatments like low-dose aspirin in reducing the frequency and severity of seizures and stroke-like events and the use of newer therapies like cannabidiols and mTOR inhibitors are being reviewed and have shown promising early results. This comprehensive narrative review summarizes the current literature on clinical management strategies, ongoing research studies, and future directions in the diagnosis and management of SWS.

Despite strong evidence supporting timely surgical evaluation, many children with drug-resistant epilepsy undergo multiple antiseizure medication (ASM) trials before surgery. Because guidelines recommend evaluation after failure of 2 appropriate ASMs, evaluation after failure of >2 ASMs serves as a clinically relevant benchmark. The aim of this study was to identify factors associated with initiation of surgical evaluation after failure of >2 ASMs and evaluate its association with seizure freedom. We performed a retrospective analysis using the Pediatric Epilepsy Research Consortium Surgery Database, including 24 US pediatric epilepsy centers. Children aged 18 years and younger who initiated epilepsy surgery evaluation between January 2018 and February 2023 were included. Timing of evaluation was defined by the number of ASM failures before first phase I evaluation (≤2 vs >2). Unadjusted analyses and multivariable logistic regression were used to identify predictors of later evaluation and assess its association with seizure freedom, adjusting for etiology, seizure type, MRI findings, and surgical procedure. Among 1,767 patients, 802 (45.4%) initiated surgical evaluation after failing ≤2 ASMs and 965 (54.6%) after failing >2 ASMs, with a median age at seizure onset of 5.96 and 4.00 years, respectively. Factors independently associated with later initiation of surgical evaluation included genetic etiology (odds ratio [OR] 1.83, 95% CI 1.28-2.60), generalized seizures (OR 2.64, 95% CI 1.58-4.40), daily seizures (OR 1.69, 95% CI 1.33-2.14), multiple seizure types (OR 1.59, 95% CI 1.39-1.82), normal MRI (OR 1.82, 95% CI 1.52-2.18), and abnormal neurologic examination (OR 2.44, 95% CI 2.01-2.96). Surgical intervention rates were similar (∼50%) between groups. Patients who initiated surgical evaluation after failure of ≤2 ASMs had significantly higher seizure freedom rates (60.8% vs 39.3%, p < 0.001). On multivariable analysis, failure of >2 ASMs before surgical evaluation was independently associated with lower odds of seizure freedom (OR 0.66, 95% CI 0.45-0.96, p = 0.028). Initiation of surgical evaluation after failure of more than 2 ASMs is associated with more complex epilepsy phenotypes and lower rates of seizure freedom. However, 80% of these patients still experienced a >50% reduction in seizures, highlighting the therapeutic benefits of timely epilepsy surgery-even when seizure freedom is unlikely-regardless of epilepsy subtype.

Focal cortical dysplasia (FCD) is the most common cause of surgically treatable drug-resistant epilepsy (DRE) in children. Surgical outcomes are poorly defined in early-onset FCD-DRE. The purpose of this study was to evaluate clinical and presurgical characteristics relating to surgical outcomes in early-life (seizure onset <4 months old) FCD-DRE. A multicenter prospective cohort was analyzed from the Pediatric Epilepsy Research Consortium (PERC) Surgery Database to identify patients with pathologically confirmed FCD-DRE and seizure onset younger than 4 months old. Clinical characteristics, presurgical workup, and surgical intervention and outcomes data were collected and analyzed. Primary outcome was to evaluate whether earlier surgery is associated with seizure freedom; secondary outcomes evaluated clinical/presurgical predictors of seizure freedom and safety. Thirty-one patients with FCD-DRE were identified from 18 PERC centers. Median age at seizure onset was 2.4 months (interquartile range 1.2-3.6 months). Four patients had focal to bilateral tonic-clonic seizures (FBTCS); 35% (n = 11) had epileptic spasms. Median age at phase 1 referral was 2.0 years (0.7-4.0 years). Median age at surgery was 2.6 years (1.1-5.5 years). Pathology was type II, 65% (n = 20); type I, 26% (n = 8); and type III, 6% (n = 2). Seizure freedom was achieved in 65% (n = 20) with median follow-up 2.5 years (1.3-4 years). Age at seizure onset/referral/surgery, surgery type, and experiencing FBTCS were not associated with seizure-free outcome. Type IIB pathology had 89% (n = 8) seizure-free outcome. Epileptic spasms had 45% seizure-free outcome. Transient neurologic deficits occurred in 2 patients, and an expected neurologic deficit in 1 (visual field cut from occipital lobectomy). There were no deaths. This study finds high rates of seizure-free outcome in epilepsy surgery for early-onset FCD-DRE across all pathologies and procedures with minimal complication rates and no deaths. Focal cortical dysplasia type IIB is associated with very high rates of seizure-free outcome. Epileptic spasms were associated with lower seizure-free outcome. The study also fails to confirm a high rate of multilobar unilateral hypoplasia with severe epilepsy in children, a type I FCD variant that has been reported as a common etiology of early-life FCD.
