The Xenopus tadpole model offers many advantages for studying the molecular, cellular and network mechanisms underlying neurodevelopmental disorders. Essentially every stage of normal neural circuit development, from axon outgrowth and guidance to activity-dependent homeostasis and refinement, has been studied in the frog tadpole, making it an ideal model to determine what happens when any of these stages are compromised. Recently, the tadpole model has been used to explore the mechanisms of epilepsy and autism, and there is mounting evidence to suggest that diseases of the nervous system involve deficits in the most fundamental aspects of nervous system function and development. In this Review, we provide an update on how tadpole models are being used to study three distinct types of neurodevelopmental disorders: diseases caused by exposure to environmental toxicants, epilepsy and seizure disorders, and autism.

Department of Neurology, Massachusetts General Hospital, Harvard Medical School, Boston, MA.
Objectives: To analyze sex differences in outcomes in Tourette syndrome (TS) and Persistent Motor or Vocal tic disorders (PMVT) in the Tourette Association of America International Consortium for Genetics (TAAICG) dataset.
Methods: The relationship between sex and clinical measures was explored in 2,403 participants (N = 2,109 with TS; N = 294 with PMVT) from the TAAICG dataset using generalized estimating equation regression models, and adjusted for age and family relationships.
Results: Female (vs male) participants with TS (25.

Objective: to analyze the implementation of care agreements developed in the CACTO program for mothers of children with Autism Spectrum Disorder.
Method: exploratory, qualitative study, guided by Unitary Caring Science and the Implementation Science methodological framework, based on the Consolidated Conceptual Framework for Implementation Research. Conducted with 20 mothers of children with Autism Spectrum Disorder, between April 2023 and February 2024, during care meetings developed in a non-governmental organization.

Background: Tourette syndrome (TS) is a prevalent neurodevelopmental disorder with an uncertain etiology. Numerous neuroimaging studies have investigated patients with TS, but their conclusions remain inconsistent. The current study attempted to provide an unbiased statistical meta-analysis of published neuroimaging studies of TS.

Neuronal Ceroid Lipofuscinosis 11 (CLN11) is an ultra-rare subtype of adult-onset Neuronal Ceroid Lipofuscinosis. Its phenotype is variable and not fully known. A 21-year-old man was evaluated in our neurogenetic outpatient clinic for early onset complex phenotype, including learning difficulties, cerebellar ataxia, cone-rod dystrophy, epilepsy, and dystonia.

The phosphatase and tensin homolog deleted on chromosome 10 (PTEN) gene is a critical tumor suppressor that plays an essential role in the development and functionality of the central nervous system. Located on chromosome 10 in humans and chromosome 19 in mice, PTEN encodes a protein that regulates cellular processes such as division, proliferation, growth, and survival by antagonizing the PI3K‑Akt‑mTOR signaling pathway. In neurons, PTEN dephosphorylates phosphatidylinositol‑3,4,5‑trisphosphate (PIP3) to PIP2, thereby modulating key signaling cascades involved in neurogenesis, neuronal migration, and synaptic plasticity.
