Autism Spectrum Disorder: Classification, diagnosis and therapy

Area of Science:

• Neurodevelopmental Disorders
• Pediatric Psychiatry
• Clinical Psychology

Background:

• Autism Spectrum Disorder (ASD) encompasses autism, Asperger's syndrome, and PDD-NOS, characterized by social communication deficits and restricted interests.
• ASD prevalence is rising, with estimates at 1 in 36 children, influenced by genetic and environmental factors.
• Comorbidities like ADHD and anxiety affect nearly 75% of individuals with ASD.

Purpose of the Study:

• To review the diagnostic criteria, risk factors, assessment tools, and current interventions for Autism Spectrum Disorder.
• To highlight the range of available treatments, from pharmacological to non-pharmacological approaches.
• To discuss emerging therapeutic strategies, including hormonal therapies and novel disease-modifying treatments.

Main Methods:

• Review of diagnostic criteria for ASD, focusing on core domains of social communication and restricted behaviors.
• Analysis of risk factors including genetics, parental history, and prenatal exposures.
• Examination of assessment scales like CARS, ASD-OC, and 3di.
• Overview of pharmacological (psychostimulants, antipsychotics, antidepressants) and non-pharmacological (music, CBT, social behavioral therapy) interventions.
• Exploration of hormonal therapies (oxytocin, vasopressin antagonists) and complementary treatments (vitamins, supplements).

Main Results:

• ASD diagnosis relies on core domains of social communication and restricted interests/behaviors.
• Multiple factors contribute to ASD risk, including genetics and environmental exposures.
• A variety of assessment tools are available to evaluate ASD symptoms.
• Pharmacological and non-pharmacological interventions provide symptomatic relief and manage comorbidities.
• Emerging therapies like hormonal treatments and disease-modifying agents show potential for core symptom improvement.

Conclusions:

• ASD is a complex neurodevelopmental disorder with increasing prevalence and significant comorbidity.
• Current interventions focus on symptomatic management and improving social and communication skills.
• Further research into disease-modifying therapies is crucial for sustained, long-term improvement in ASD.
