Attention Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder characterized by symptoms of inattention, hyperactivity, and impulsivity. It is one of the most common childhood disorders, affecting approximately 8-10% of children and adolescents worldwide. ADHD can persist into adulthood, affecting approximately 4-5% of adults.

Diagnostic Criteria (DSM-5)

To diagnose ADHD, the following criteria must be met:

Diagnostic Criteria

1. A persistent inattention and/or hyperactivity-impulsivity pattern that interferes with functioning or relationships.

2. At least five inattention and/or hyperactivity-impulsivity symptoms must be present in two or more settings (e.g., home, school, work).

3. Symptoms must have been present for at least six months.

4. Another mental disorder cannot better explain symptoms.

Subtypes of AD/HD

The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) recognizes three subtypes of ADHD:

1. Predominantly Inattentive Type (ADHD-PI):

• Symptoms of inattention predominate.
• Few or no symptoms of hyperactivity and impulsivity.

2. Predominantly Hyperactive-Impulsive Type (ADHD-PH):

• Symptoms of hyperactivity and impulsivity predominate.
• At least 6 symptoms of hyperactivity and impulsivity.
• Few or no symptoms of inattention.

3. Combined Type (ADHD-C):

• Symptoms of both inattention and hyperactivity-impulsivity are present.
• At least 6 symptoms of inattention and 6 symptoms of hyperactivity-impulsivity.

Specifiers of AD/HD

The DSM-5 also includes specifiers to indicate the severity and course of ADHD:

Severity Specifiers

1. Mild: Few symptoms, minimal impairment.

2. Moderate: Symptoms cause significant impairment.

3. Severe: Many symptoms, significant impairment.

Course Specifiers

1. In partial remission: Symptoms have decreased in severity.

2. In full remission: Symptoms have disappeared.

Other Specifiers

1. With other mental health conditions: ADHD co-occurs with other mental health conditions (e.g., anxiety, depression).

2. With sleep disorders: ADHD co-occurs with sleep disorders (e.g., insomnia, sleep apnea).

3. With substance use disorders: ADHD co-occurs with substance use disorders.

Additional Subtypes (not officially recognized in DSM-5)

1. Attention Deficit Disorder (ADD): Older term for ADHD-PI.

2. Hyperkinetic Disorder: Similar to ADHD-PH.

Prevalence and Demographics

Here's an overview of the prevalence and demographics of Attention Deficit/Hyperactivity Disorder (ADHD):

Prevalence

• ADHD is one of the most common neurodevelopmental disorders worldwide.
• According to the Centers for Disease Control and Prevention (CDC), approximately 9.4% of children (6.1 million) and 4.4% of adults (10.5 million) in the United States have ADHD.
• Global prevalence estimates range from 5-8% for children and 2.5-4% for adults.

Demographics

• Age: ADHD symptoms typically appear between 6-12 years old. While symptoms may decrease with age, ADHD can persist into adolescence and adulthood.
• Sex: Boys are 1.5-3 times more likely to be diagnosed with ADHD than girls. Women are more likely to have inattentive symptoms.
• Ethnicity: No significant differences in prevalence exist among ethnic groups. However, minority groups may face disparities in diagnosis and treatment.
• Socioeconomic Status: Lower socioeconomic status is linked to higher ADHD prevalence, possibly due to limited access to healthcare and diagnostic services.

Underdiagnosis and Misdiagnosis

• Children: Often misdiagnosed as "lazy" or "unmotivated."
• Adults: Frequently misdiagnosed with anxiety, depression, or substance use disorders.
• Women: More likely to be underdiagnosed or misdiagnosed.

2. Perinatal factors: Premature birth, low birth weight.

3. Neurotoxins: Exposure to lead, mercury, and other toxins.

4. Nutrition and diet: Food additives, sugar, and omega-3 deficiency.

Neurobiological Factors

1. Brain structure: Differences in prefrontal cortex, basal ganglia, and cerebellum.

2. Neurotransmitter imbalance: Dopamine, serotonin, and norepinephrine.

3. Brain function: Abnormalities in executive function, attention, and impulse control.

Other Factors

1. Premature birth and low birth weight.

2. Traumatic brain injury.

3. Infections (e.g., strep throat).

4. Sleep disorders.

5. Social and environmental factors (e.g., poverty, neglect).

The interplay between Factors

1. Gene-environment interaction: Genetic predisposition + environmental triggers.

2. Epigenetics: Environmental factors influencing gene expression.
