Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that affects both children and adults. ADHD is characterized by inattention, hyperactivity, and impulsivity, which can have a significant impact on daily functioning. In adults, ADHD can manifest in three different types, each with its own unique set of symptoms.   The inattentive type of ADHD in adults is characterized by difficulty in paying attention to details and sustaining attention on tasks or activities. Individuals with this type of ADHD may be easily distracted, forgetful, and disorganized. They may struggle with completing tasks and following instructions. For instance, an individual with inattentive ADHD may forget important deadlines or appointments, have difficulty focusing during meetings, or struggle to organize their workspaces.   The hyperactive-impulsive type of ADHD in adults is characterized by hyperactivity and impulsivity. Individuals with this type of ADHD may experience restlessness, fidgeting, and difficulty sitting still. They may engage in impulsive behavior such as interrupting others, speaking without thinking, and taking risks. For example, an individual with hyperactive-impulsive ADHD may struggle to sit still during long meetings or conversations, interrupt others while they are speaking, or make impulsive purchases without considering the consequences.   The combined type of ADHD in adults is a combination of inattentive and hyperactive-impulsive symptoms. This type of ADHD is the most common in adults, and symptoms can vary in severity. Individuals with combined ADHD may experience difficulty with attention, hyperactivity, and impulsivity, which can impact daily functioning in work, school, or social settings. For instance, an individual with combined ADHD may struggle to focus on important tasks, feel restless and fidgety during meetings, or interrupt others during conversations.   ADHD is a complex disorder that can manifest in different ways in adults. The three types of ADHD in adults are inattentive, hyperactive-impulsive, and combined. Each type has its own unique set of symptoms, which can impact daily functioning in different ways. Understanding the different types of ADHD in adults is essential to provide appropriate treatment and support for individuals with this disorder.
