What Are Neurodevelopmental Disorders?
Neurodevelopmental disorders are conditions that emerge during childhood development and affect how the brain processes information, regulates behavior, and manages attention. These are typically lifelong conditions that have gone undiagnosed. The chronic relapser may have spent their entire life with the disorder, and substance use became their way to function, focus, and fit-in.
Understanding Neurodevelopmental Disorders
Attention-Deficit/Hyperactivity Disorder (ADHD)
Persistent patterns of inattention, hyperactivity, and impulsivity that interfere with functioning and development. Strongly associated with substance use disorders.
What it looks like:
- Chronic difficulty completing tasks and following through
- Impulsive decision-making, including substance use
- Using stimulants to finally focus and feel "normal"
- Using alcohol or sedatives to quiet the constant mental restlessness
Autism Spectrum Disorder (ASD)
Persistent challenges with social communication and interaction, along with restricted or repetitive patterns of behavior and interests.
What it looks like:
- Difficulty reading social cues, missing the unspoken context
- Using alcohol to reduce social anxiety and "fit in" at gatherings
- Rigid routines that become disrupted by stress
- Using cannabis or other substances to dampen overwhelming sensory experiences
Specific Learning Disorders
Difficulties in reading (dyslexia), written expression, or mathematics that are not explained by intellectual ability, creating lifelong patterns of frustration, shame, and compensatory behaviors.
What it looks like:
- History of academic struggles despite obvious intelligence
- Using substances to escape the shame and frustration of lifelong learning difficulties
- Developing elaborate strategies to hide reading or writing problems from others
- Gravitating toward substance use in social groups where academic achievement doesn't matter
Dual Diagnosis Stats:
Prevalence: 21% of individuals with substance use disorders have comorbid ADHD, approximately 1 in 5 patients¹
Co-Occurrence: Adults with ADHD are 69% more likely to develop substance use disorder, even after controlling for other factors²
Relapse Risk: Individuals with Autism Spectrum Disorder (without intellectual disability) have twice the risk of substance use problems compared to the general population³
How Do Neurodevelopmental Disorders Contribute to Relapse?
Neurodevelopmental disorders create lifelong vulnerabilities that standard addiction treatment often fails to address. The person may complete treatment appearing “successful”—but the underlying condition that drove substance use remains untreated.
- Strongly Ingrained Patterns of Self-Medication
Substance use becomes a normalized part of their life. - Impulsivity Undermines Recovery
ADHD in particular involves neurological difficulty with impulse control. - Treatment Programs Miss the Diagnosis
Most programs focus only on behavior and motivation.
How Neurodevelopmental Disorders Are Identified & Diagnosed
Diagnosing neurodevelopmental disorders in adults with active substance use presents significant challenges. ADHD symptoms can look like stimulant withdrawal; ASD traits can be masked by substances used for social lubrication. Accurate diagnosis requires extended observation during sustained sobriety—and clinicians who know what to look for.
What proper diagnosis requires:
- Developmental history going back to childhood
- Assessment during sustained abstinence to separate symptoms from substance effects
- Comprehensive neuropsychological testing when indicated
- Evaluation for multiple conditions—ADHD and ASD frequently co-occur, as do ADHD and learning disorders
"About one in five patients with substance use disorder has undiagnosed ADHD. In short-term programs, there isn't time to identify or treat it. Long-term treatment allows us to separate substance effects from other underlying conditions."
Long-Term Treatment for Neurodevelopmental Disorders and Addiction
Standard addiction treatment may achieve short-term sobriety, but if the underlying ADHD, ASD, or learning disorder remains unaddressed, the drive to self-medicate returns. Burning Tree’s long-term, progress-based model provides time for accurate diagnosis and integrated treatment.
- Time for Comprehensive Assessment
Accurate diagnosis requires months of observation in sobriety. - Treating Both Conditions Together
Long-term treatment allows for a comprehensive therapeutic approach that addresses the neurodevelopmental symptoms. - Building Skills for a Different Brain
Recovery means learning strategies that work with their neurology.
