Abstract

Autism spectrum disorder (ASD) deals with several symptoms, including language and speech impairment and developmental delays. The main brain regions affected could be the prefrontal cortex (PFC) or the temporal lobe. The detrimental features could include oxidative stress, mitochondrial dysfunction, and neuroinflammation. Most often, these phenomena are interrelated and can lead to one another, creating a vicious cycle. They also influence the regulation of certain genes involved in the pathogenesis of ASD or related behavior. In the brain regions prone to these detrimental features, a cascade of free radicals, inflammatory cytokines, and mitochondrial energy disruptions is initiated. These actions during the prenatal or developmental stage of the child potentially lead to ASD symptomatic features, such as social isolation, communication difficulty, speech and language impairment, cognitive dysfunction, and intellectual disability. The more recent theories, including genetics, epigenetics, and the gut-brain axis, have been demonstrated to play a greater role in ASD pathology, often being associated with the more common ones as mentioned above. We also introduced some of the neurological disorders possessing shared genetic and behavioral traits with ASD. Many genes playing a role in ASD-like features and their potential targeted drugs were explained briefly. However, there are limited therapeutic options, and molecular pathways related to this disorder are less explored. Currently, researchers and therapists are racing to uncover a concrete remedy. This review also provides a brief outline of potential antioxidant, mitochondrial, and anti-inflammatory therapies. We finally included some novel strategies to diagnose and manage autistic pathology and symptoms.
