Selection of Young Animal Models of Autism over Adult: Benefits and Limitations.

This review looked at whether using younger animals (rather than adult animals) is better for autism research. The researchers found that younger animals might show clearer behavioral differences that are relevant to autism. They suggest that studying younger animals could help scientists better understand early signs of autism and develop treatments that work earlier in life.

This 2023 review examines the advantages and disadvantages of using younger versus adult animal models in autism research. The authors analyzed various factors including age, sex, body weight, sample sizes, and autism-inducing agents across different animal studies. The review suggests that behavioral parameters show clearer differentiation in younger animal models compared to adult models. The authors conclude that young and adolescent animal models may be more suitable for autism research, potentially supporting early detection strategies and more effective interventions.

However, the complex pathophysiology of autism and limited understanding of drug targets continue to make standardization and validation of animal models challenging.

The findings suggest that research focusing on younger animal models may be more relevant for understanding early autism development and designing age-appropriate interventions. However, translation to human clinical practice requires caution given the preliminary nature of these conclusions.

This is a review paper without original data. No sample sizes or study methodology details are provided. The evidence supporting conclusions about younger versus adult models is not clearly specified.

Autism is a complex neurodevelopmental broad-spectrum disorder characterized by social interaction, and aberrant restrictive and repetitive behavior. The complex pathophysiology and unexplored drug targets make it difficult to standardize and validate the animal models of autism. The review was purposed for determining the benefits of younger animal models over adult models of autism. Similarly, animal models with respect to age, sex, body weight, number of animals used, along with autism inducing agents have been reviewed in this article.

The differentiation of behavioral parameters has shown the benefits in the selection of younger animal models. Thus, we conclude that young and adolescence animal models of autism will be supporting for early detection and interventions with significant results.
