Autism Spectrum Disorder (ASD) Evaluations at the Neuropsychological Assessment Center of Houston
Autism Spectrum Disorder (ASD) is a neurological and developmental disorder that affects social communication, behavior, and overall functioning from childhood through adulthood. Neuropsychological Assessment Center of Houston, Inc. (NACH) offers comprehensive autism evaluations designed to support children and young adults in their development and long-term mental health success. The neuropsychologists at NACH evaluate autism within the context of other neurological, cognitive, emotional, and behavioral considerations.
What Is ASD?
ASD is defined as a neurodevelopmental disorder characterized by deficits in:
- Social communication and nonverbal communication
- Social emotional reciprocity and social interactions
- Restricted and repetitive patterns of behavior
- Sensory sensitivities
ASD is listed in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), which is published by the American Psychiatric Association and provides standardized criteria for the classification and diagnosis of mental disorders.
Individuals with autism may have a wide range of traits that can affect their communication, language, thinking, and relationships.
Common Autism Symptoms and Early Signs
In Early Childhood:
- Reduced eye contact and facial expressions
- Deficits or delays in language skills
- Odd and Rrepetitive behavior or atypical play
- Lack of interest in social interactions
In Later Development:
- Difficulty interpreting others’ intentions
- Challenges in maintaining and understanding peer relationships
- Highly restricted interests
- Sensory sensitivities
Early childhood screening is critical, as early signs allow for evidence-based interventions that support healthy development.
What Causes ASD?
Research studies and clinical trials indicate various factors that may contribute to the risk of ASD, including, but not limited to:
- Genetic mutations/ Family history of ASD
- Advanced parental age and older parents
- Low birth weight
Research suggests ASD is not caused by childhood vaccines — a conclusion supported by the Centers for Disease Control and multiple national library research reviews.
Co-Occurring Conditions Associated With ASD
Many children and young adults with autism experience co- occurring conditions such as:
- Anxiety disorders
- Language Disorders
- Intellectual disability
- Sleep difficulties
- Emotional/Behavioral dysregulation
These mental health conditions often require coordinated care from a team of healthcare providers, including medical, developmental, and psychological specialists.
