Summary
Adolescents with attention-deficit/hyperactivity disorder (ADHD) show earlier and more severe substance use disorder (SUD) patterns, regardless of cultural context. Early ADHD diagnosis and treatment are crucial for better SUD prognosis and reduced societal costs.
Area of Science:
- Child and Adolescent Psychiatry
- Neurodevelopmental Disorders
- Addiction Medicine
Background:
- Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder.
- Substance use disorder (SUD) is a significant public health concern among adolescents.
- Cultural factors and drug availability may influence SUD patterns.
Purpose of the Study:
- To investigate the patterns of SUD in Iranian adolescents with and without a history of ADHD.
- To explore the impact of ADHD on SUD development within a specific cultural context.
Main Methods:
- A case-control study involving interviews by a child psychiatrist.
- Utilized the Kiddie Schedule for Affective Disorder and Schizophrenia for school-age children (K-SADS), Opium Treatment Index (OTI), and Global Assessment Functioning (GAF).
- Statistical analysis included chi-square, T-tests, and Fisher's exact test.
Main Results:
- Adolescents with ADHD initiated substance use, abuse, and dependency at a younger age (p=0.0001).
- They experienced a shorter latency from first use to dependence/abuse (p=0.0001) and exhibited more severe substance use (p<0.05).
- ADHD group showed greater functional impairment (p=0.0007) and higher comorbidity rates (p=0.03).
Conclusions:
- Findings align with Western and non-Western studies, indicating ADHD's significant role in SUD development.
- ADHD appears to be a stronger predictor of SUD than cultural barriers or drug availability.
- Early diagnosis and treatment of ADHD are recommended to improve SUD prognosis and reduce associated healthcare costs.

01:30Attention-Deficit/Hyperactivity Disorder
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.

01:24Substance Use Disorders Affecting Sleep
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

01:24Drug Toxicity: Risk factors
Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...
01:15Drug Abuse and Addiction: Pharmacological Phenomena
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not necessarily...
01:29Stimulants
Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

01:19Autism Spectrum Disorder
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
