What is ADHD (Attention-Deficit/Hyperactivity Disorder)?

ADHD (Attention-Deficit/Hyperactivity Disorder) is a developmental disorder characterized by persistent symptoms of inattention, hyperactivity, and impulsivity that affect an individual's daily life and social functioning.

Main Symptoms

  • Inattention: Difficulty sustaining focus, frequent forgetfulness, poor organization, etc.
  • Hyperactivity: Restlessness, constant movement
  • Impulsivity: Acting without thinking, difficulty waiting for turns

Types of ADHD

  • Predominantly Inattentive Type (ADHD-I): Primarily inattentive symptoms
  • Predominantly Hyperactive-Impulsive Type (ADHD-HI): Prominent hyperactivity and impulsivity
  • Combined Type (ADHD-C): Both inattentive and hyperactive-impulsive symptoms

Diagnostic Criteria (Based on DSM-5)

  • Symptoms must have been present before the age of 12
  • Symptoms must be observed in multiple environments (home, school, workplace, etc.)
  • Clear functional impairment in academic, occupational, or interpersonal settings

Diagnosis Process

ADHD diagnosis involves interviews, behavioral observations, psychological testing, and screening tests. Differential diagnosis from other mental disorders is also crucial.

Treatment and Support

  • Medication (e.g., methylphenidate, atomoxetine)
  • Cognitive Behavioral Therapy (CBT)
  • Adjustments and support in daily life

With proper treatment and support, individuals with ADHD can improve their quality of life.

What is the DSM-5 Diagnostic Logic for ADHD?

1. Symptom Criteria

The following symptoms must persist for at least 6 months.

  • Inattention Symptoms: For individuals 16 years or younger, at least 6 out of 9 symptoms are required. For those 17 years or older, at least 5 symptoms are required.

    • Difficulty organizing tasks and activities
    • Avoids or dislikes tasks requiring sustained mental effort
    • Loses necessary items frequently
    • Easily distracted by external stimuli
    • Forgetful in daily activities
  • Hyperactivity-Impulsivity Symptoms: Must meet the age-specific criteria for the following 9 symptoms.
    • Fidgets with or taps hands or feet, or squirms in seat
    • Leaves seat in situations where remaining seated is expected
    • Runs about or climbs in inappropriate situations
    • Difficulty playing or engaging in leisure activities quietly

    • Blurts out answers before questions are completed
    • Difficulty waiting for their turn
    • Interrupts or intrudes on others' conversations or activities

2. Age of Onset

Some symptoms must have been present before the age of 12.

3. Symptoms in Multiple Settings

Symptoms must be observed in at least two different environments (e.g., home, school, workplace).

4. Clear Functional Impairment

Symptoms must cause clear impairment in academic, occupational, or interpersonal functioning.

5. Symptoms Not Explained by Other Disorders

Symptoms cannot be better explained by other mental disorders such as schizophrenia, mood disorders, or anxiety disorders.

Summary of Diagnostic Logic

All criteria must be met.

  • Number of inattention or hyperactivity-impulsivity symptoms meets the criteria
  • Presence of symptoms before age 12
  • Confirmation of symptoms in multiple settings
  • Clear functional impairment
  • Symptoms not explained by other disorders

Based on this diagnostic logic, accurate evaluation and diagnosis are conducted.
