Recent evidence suggests that VPA exposure during adulthood may also elicit autism spectrum disorder (ASD)-like features by altering key signalling pathways, such as phosphoinositide 3-kinase/AKT/mammalian target of rapamycin (PI3K-AKT-mTOR), and cause behavioural and neuromorphological deficits. The study explored the neuroprotective properties of ferulic acid (FA) in VPA-induced cognitive and behavioural impairments. Zebrafish were exposed to VPA at 500 μM for four consecutive days to induce ASD-like features. After 4 days of VPA exposure, they were treated with FA (50, 100, and 200 mg/kg) and risperidone (0.5 mg/kg) for 4 days. Behavioural (T-maze, Novel Tank Driving Test (NTDT), and social interaction), biochemical (oxidative markers), molecular changes (PI3K, mTOR by ELISA, and AKT by immunohistochemistry), and histopathological analyses were performed to confirm the neuroprotective properties of ferulic acid (FA).
