Music alleviates cognitive impairments in an animal model of autism.

Researchers used rats with autism-like behaviors to test if music helps with thinking and social skills. Baby rats listened to Mozart piano music for 4 hours daily for 30 days. The music helped improve social behavior (especially in males), learning, and memory skills compared to rats that didn't hear music. This early research suggests music might help children with autism, but more human studies are needed.

This preclinical study investigated music therapy effects in a valproic acid (VPA) rat model of autism. Male and female rat pups exposed to VPA prenatally (modeling autism-like behaviors) were treated with Mozart's piano sonata K.448 for 30 days (4 hours daily) from postnatal day 21-50. VPA-exposed rats showed impaired social interaction, learning, and memory compared to controls. Music intervention improved sociability particularly in males, enhanced spatial learning in males, and improved spatial and passive avoidance memory in both sexes, with stronger effects in females for passive avoidance.

The study provides preliminary evidence that music exposure may ameliorate some cognitive and social deficits in this autism animal model.

Provides preliminary support for music therapy in autism, particularly for cognitive and social development. Suggests potential sex-specific benefits. However, this is early-stage animal research requiring human studies before clinical recommendations can be made.

Animal model findings may not translate to humans. Sample size not reported. Single intervention type (Mozart piano sonata) limits generalizability. Short-term study duration. Authors acknowledge need for more investigation.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by core symptoms including impairment in social communication and restrictive and repetitive behaviors and interests. Music has emerged in the past decade as an intervention therapy for children with ASD. The aim of the present study was to evaluate the effects of music on cognition impairments in the valproic acid (VPA) rat model of autism. The VPA was administered for animal modeling of autism on embryonic day 12.5 (E12.5) (600 mg/kg).

Male and female pups were sub divided into four main groups (Saline.Non-music, VPA.Non-music, Saline.Music, and VPA.Music). The rats in the music groups were exposed to Mozart's piano sonata K.448 for 30 days (4 h/day), from postnatal day (PND) 21 to 50. Autistic-like behaviors were tested using a social interaction, the Morris water maze (MWM), and a passive avoidance tasks at the end of the PND 50. Our results demonstrated that VPA-exposed rat pups had significantly lower sociability and social memory performance compared with the saline-exposed rats in both sexes.

VPA-exposed rat pups exhibited learning and memory impairments in the MWM and passive avoidance tasks. Our results demonstrated that music improved sociability in VPA-exposed rats, especially in males. Furthermore, our findings revealed that music improved learning impairments in VPA-exposed male rats in MWM task. In addition, music improved spatial memory impairments in VPA-exposed rats of both sexes.

We also found that music improved passive avoidance memory impairments in VPA-exposed rats of both sexes, especially in females. More investigation in future studies are needed.
