The results indicate that neonatal complications and prematurity alone do not significantly predict dyslexia diagnosis, but a negative trend was observed between intraventricular haemorrhage and periventricular leukomalacia and reading comprehension and word decoding performance. These findings suggest that prematurity, in the absence of other risk factors, does not necessarily result in dyslexia, but when combined with specific neonatal conditions, it may increase the severity of reading difficulties.

However, the effects of catechol on zebrafish redox and behaviour are unknown. The aim of this study was to investigate the effects of catechol on oxidative stress levels in early zebrafish development and on behaviour in later stages of zebrafish development and to attempt to intervene in this effect with music therapy. We exposed zebrafish adults and juveniles to catechol separately, tested zebrafish juveniles for various redox indices and found that zebrafish juveniles had increased levels of reactive oxygen species and decreased total antioxidant capacity and lipid peroxidation capacity, and we tested zebrafish adults for behavioural studies and found that anxiety behaviours increased as social cohesion decreased. We then conducted a music therapy intervention for catechol exposure in adult zebrafish and found that music therapy exacerbated catechol-induced behavioural abnormalities and altered oxidative levels, whether zebrafish were exposed to both catechol and classical music or whether the catechol exposure was followed by a 12-day classical music intervention after 12 days of catechol exposure. In summary, this study revealed for the first time that catechol caused redox imbalance in juvenile zebrafish and socially disturbed, anxious behaviour in adults and found that music treatment worsened this behavioural abnormality.

This article examines genetic alterations linked to ASD, with a specific emphasis on single nucleotide polymorphisms (SNPs) and single nucleotide variants (SNVs). Recent genome-wide association studies (GWAS) have identified several genetic variations associated with ASD. Although their precise roles remain unclear, such genetic polymorphisms and variations significantly influence several neurodevelopmental processes. Mutations in <i>SHANK3</i> and <i>NRXN1</i>, for example, disrupt synaptic activity and neurotransmission, contributing to ASD and intellectual deficits. Similarly, <i>PTEN</i> and <i>MECP2</i>, crucial for brain development, are associated with abnormal cell proliferation and neurodevelopmental disorders when mutated. <i>CHD8</i>, a key regulator of chromatin remodelling, is strongly linked to ASD, with its mutations impacting transcriptional regulation and neurodevelopment, while mutations in <i>SCN2A</i> disrupt neuronal excitability and synaptic transmission. In this review, we discuss SNPs and SNVs across these six key genes, to summarise their impact on the aetiology of ASD.
