Pathophysiology of autism: current opinions

Area of Science:

• Neuroscience
• Autism Spectrum Disorder Research
• Neurochemistry

Background:

• Increasing research focuses on the neurochemical underpinnings of autism pathophysiology.
• Abundant publications necessitate a focused review of recent findings.
• Understanding the central nervous system (CNS) molecules linked to autistic behavior is crucial.

Purpose of the Study:

• To review significant neurochemical data from the last decade and recent research.
• To highlight the interplay between serotonergic, immunological, and endocrinological systems in autism.
• To examine the influence of genetic and environmental factors on these neurochemical systems.

Main Methods:

• Comprehensive literature review of neurochemical research in autism.
• Analysis of recent research data from the authors' center.
• Focus on molecules affecting the CNS and their relation to autistic behaviors.

Main Results:

• Detailed the mutual relationship between serotonergic, immunological, and endocrinological systems.
• Emphasized the interaction of these systems with genetic and environmental factors (prenatal, perinatal, postnatal).
• Noted the influence of age, sex, race, IQ, and pubertal stage on biological data.

Conclusions:

• The complexity and variability of neurochemical interactions likely explain autism's heterogeneous phenotypes and biological findings.
• Genetic, neuroanatomical, and neurophysiological data are relevant to neurochemical perspectives in autism.
• Further research into these intricate neurochemical pathways is warranted.
