# Advantages and Limitations of Animal Schizophrenia Models

## TL;DR

This paper discusses the use of animal models to study schizophrenia, highlighting their benefits and limitations in understanding the disease and developing new treatments.

## Contribution

The paper provides an overview of different types of schizophrenia animal models and their limitations in reflecting human disease.

## Key findings

- Animal models of schizophrenia include pharmacological, genetic, and neurodevelopmental approaches.
- These models induce brain changes in rodents that resemble human schizophrenia symptoms.
- Despite their usefulness, animal models have limitations and do not fully replicate human mental illness.

## Abstract

Mental illness modeling is still a major challenge for scientists. Animal models of schizophrenia are essential to gain a better understanding of the disease etiopathology and mechanism of action of currently used antipsychotic drugs and help in the search for new and more effective therapies. We can distinguish among pharmacological, genetic, and neurodevelopmental models offering various neuroanatomical disorders and a different spectrum of symptoms of schizophrenia. Modeling schizophrenia is based on inducing damage or changes in the activity of relevant regions in the rodent brain (mainly the prefrontal cortex and hippocampus). Such artificially induced dysfunctions approximately correspond to the lesions found in patients with schizophrenia. However, notably, animal models of mental illness have numerous limitations and never fully reflect the disease state observed in humans.
