Summary: Children with neurodevelopmental conditions attending developmental assessment services have high rates of mental health concerns, with approximately 48% of preschool and 61% of school-age children having subclinical or clinically elevated scores. These rates remain high even after excluding items specifically related to neurodevelopmental concerns. School-aged females are more likely to have elevated internalizing problems compared to males (67% vs 48%). Children with multiple DSM-5 diagnoses also show a greater rate of subclinical or clinically elevated scores. These findings highlight the importance of identifying and addressing mental health concerns in children attending developmental assessment services.

Summary: Neurodevelopmental Disorders (NDDs) encompass a wide range of disorders, including autism spectrum disorders (ASD) and schizophrenia (SCZ), which are linked to brain developmental processes. The clinical treatment of these disorders has traditionally focused on symptom management due to the variability in developmental disruption and limited knowledge of the underlying molecular mechanisms. With the identification of several hundred genes associated with ASD and SCZ, there is potential for new therapeutic approaches and the opportunity for precision medicine. This review discusses the progress in research technologies that enhance our understanding of disease progression and highlights advances in targeted clinical treatment and ongoing preclinical efforts in NDD precision medicine.

Summary: Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by impairments in social interaction and repetitive behaviors, with mitochondrial dysfunction considered as an important underlying pathogenic factor. However, the pathophysiology of ASD is still not fully understood, with mutations in synaptic genes also playing a role in the disorder. Mitochondria play diverse functions at the synapse, beyond their classical role as energy providers.

Summary: CTNNB1 is a gene that encodes b-catenin and plays a crucial role in the Wnt signaling pathway, regulating cellular homeostasis. While most studies on CTNNB1 have focused on its role in cancer, it has recently been found to be involved in neurodevelopmental disorders (NDDs) such as intellectual disability, autism, and schizophrenia. Mutations in CTNNB1 disrupt the Wnt signaling pathway, leading to abnormalities in gene transcription, synaptic plasticity, neuronal apoptosis, and neurogenesis. This review explores various aspects of CTNNB1 and its physiological and pathological functions in the brain, as well as recent research on its expression and function in NDDs. The findings suggest that CTNNB1 might be one of the top high-risk genes for NDDs and a potential therapeutic target for their treatment.

Summary: Recent studies have shown that overactivated mTORC1 in the cerebellum can lead to autism-like features and cognitive deficits, whereas ablation of 4E-BP2 in Purkinje cells causes reduced cell numbers, increased regularity of action potential firing, and deficits in motor learning. Surprisingly, mice with selective ablation of 4E-BP2 exhibit impaired spatial memory but normal social interaction and no deficits in repetitive behavior, suggesting independent cerebellar mechanisms controlling social behavior and memory formation downstream of mTORC1/4E-BP2.

Summary: Research shows that disruption of the Bmal1 gene leads to social impairments, repetitive behaviors, and motor learning disabilities in mice, similar to core behavioral deficits in ASD. Abnormal cell density and morphology were found in the cerebellar Purkinje cells of Bmal1 knockout mice. Electrophysiological recordings revealed enhanced synaptic transmission and reduced firing rates in these cells. Differential expression of genes associated with ASD and ataxia and dysregulated pathways were identified in the cerebellum of Bmal1 knockout mice. The antidiabetic drug metformin was able to reverse the hyperactivation of mTORC1 and alleviate behavioral and cellular deficits in Bmal1 knockout mice. Conditional deletion of Bmal1 in cerebellar Purkinje cells alone was sufficient to replicate autistic-like behaviors and cellular changes. These findings suggest a previously unknown role for Bmal1 disruption in cerebellar dysfunction and autistic-like behaviors, providing experimental evidence for the involvement of circadian clock gene dysregulation in the pathogenesis of ASD.

Summary: MAPK interacting protein kinases 1 and 2 (Mnk1/2) regulate various functions by phosphorylating their substrate eIF4E on Ser209. Deletion of Mnk1/2 impairs synaptic plasticity and memory in mice, but ablation of phospho-eIF4E (Ser209) has no effect on these processes, indicating that Mnk1/2 have additional downstream effectors in the brain. Synaptic Ras GTPase activating protein 1 (Syngap1), encoded by an autism gene, is identified as a downstream target of Mnk1. Knockdown of Syngap1 reverses memory deficits in Mnk double knockout mice and pharmacological inhibition of Mnks rescues autism-related phenotypes in Syngap1(+/-) mice.

Summary: The granule fraction contains proteins implicated in stalled polysome function, and the ribosomes in this fraction are mainly stalled in the hybrid state. Ribosome profiling reveals longer footprints on mRNAs associated with FMRPs and an increase in ribosome occupancy on mRNAs encoding RNA binding proteins. The data supports a model in which specific sequences in mRNAs stall ribosomes during translation elongation in neurons.

Summary: The phosphorylation of eIF4E plays a critical role in the translational control of long-term synaptic plasticity and the selective translation of the Wnt signaling pathway. Phospho-ablated Eif4e(S209A) Knockin mice exhibit impaired maintenance of dentate gyrus LTP, while the basal perforant path-evoked transmission and LTP induction are unaffected. These findings suggest that activity-induced eIF4E phosphorylation is essential for LTP maintenance and the regulation of the mRNA cap-binding complex.

Summary: Repeated or prolonged general anesthesia during the early postnatal period leads to long-lasting impairments in memory formation by causing selective apoptosis and loss of parvalbumin-positive inhibitory interneurons in the hippocampus of mice. This loss disrupts the regulation of neuronal circuits and memory consolidation. Preventing the loss of parvalbumin neurons rescues anesthesia-induced deficits in pyramidal cell inhibition and long-term memory, while partial depletion of these neurons in neonates is sufficient to impair long-term memory.
