Abstract
Autism spectrum disorder (ASD) is a neurological condition that directly affects brain
functions and can culminate in delayed intellectual development, problems in verbal communication,
difficulties in social interaction, and stereotyped behaviors. Its etiology reveals a genetic basis
that can be strongly influenced by socio-environmental factors. Ion channels controlled by ligand
voltage-activated calcium, sodium, and potassium channels may play important roles in modulating
sensory and cognitive responses, and their dysfunctions may be closely associated with neurodevelopmental
disorders such as ASD. This is due to ionic flow, which is of paramount importance to
maintaining physiological conditions in the central nervous system and triggers action potentials,
gene expression, and cell signaling. However, since ASD is a multifactorial disease, treatment is directed
only to secondary symptoms. Therefore, this research aims to gather evidence concerning the
principal pathophysiological mechanisms involving ion channels in order to recognize their importance
as therapeutic targets for the treatment of central and secondary ASD symptoms.
