What is definition of Attention-Deficit/Hyperactivity Disorder (ADHD) in Mental Health Conditions?

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that manifests in childhood and often persists into adulthood. It is characterized by a persistent pattern of inattention, impulsivity, and hyperactivity that is atypical for an individual’s developmental level.

Individuals with ADHD may present symptoms such as difficulty sustaining attention, being easily distracted, trouble organizing tasks and activities, forgetfulness, impulsivity (acting without thinking), and excessive or inappropriate motor activity.

There are three subtypes of ADHD:

1. Predominantly inattentive presentation: Individuals primarily display symptoms of inattention, struggling to focus or follow instructions.
2. Predominantly hyperactive/impulsive presentation: Individuals primarily exhibit symptoms of hyperactivity and impulsivity, finding it challenging to sit still or control impulses.
3. Combined presentation: Individuals demonstrate symptoms of both inattention and hyperactivity/impulsivity.

To diagnose ADHD, symptoms must be present in multiple settings (e.g., home, school, work) and cause significant impairment in daily functioning.

It’s important to note that the specific causes of ADHD are still being researched, but it is believed to involve a combination of genetic and environmental factors. Treatment approaches for ADHD often include medication, behavioral interventions, and psychoeducation to help manage symptoms and improve overall functioning.
