What Is ADHD?

ADHD is a neurodevelopmental disorder characterized by persistent patterns of inattention, hyperactivity, and impulsivity that interfere with daily functioning. According to the latest diagnostic guidelines, it impacts children, teens, and adults alike, often persisting into adulthood.

Symptoms must be present before age 12 and occur in multiple settings, like home, school, or work. Early identification leads to better outcomes—let's dive into the 3 types of ADHD to see which resonates with you.

The 3 Types of ADHD: Breaking Them Down

The 3 types of ADHD are defined by symptom dominance. Diagnosticians use criteria like those from the American Psychiatric Association to classify them.

1. Predominantly Inattentive ADHD (ADHD-PI)

Inattentive ADHD is the "dreamer" type. People with this struggle more with focus than fidgeting. Common in girls and adults, it's often underdiagnosed because it's less disruptive.

• ✅ Frequently loses items like keys or phones
• ✅ Makes careless mistakes in work or school
• ✅ Daydreams or zones out during conversations
• ✅ Avoids tasks requiring sustained mental effort
• ✅ Forgets daily responsibilities, like paying bills

If you're organized but can't start tasks, this might be you. Symptoms must occur at least 6 days a week for 6+ months in adults.

2. Predominantly Hyperactive-Impulsive ADHD (ADHD-HI)

The "engine that won't turn off." Hyperactive ADHD involves excessive movement and snap decisions, more noticeable in boys and young children.

• ✅ Fidgets, taps feet, or squirms constantly
• ✅ Talks excessively or interrupts others
• ✅ Can't wait for turns; blurts out answers
• ✅ Feels "on the go" like driven by a motor
• ✅ Engages in risky behaviors without thinking

This type decreases with age but can evolve into inner restlessness in adults.

3. Combined ADHD (ADHD-C)

The most common, Combined ADHD blends both inattention and hyperactivity. It presents the fullest challenge, affecting about 60-70% of cases.

• ✅ All symptoms from inattentive and hyperactive types
• ✅ Struggles with organization and impulse control
• ✅ High emotional reactivity and frustration
• ✅ Difficulty in relationships due to forgetfulness + interruptions
