Which type of disorder is characterized by difficulties with attention and hyperactivity?

Attention-Deficit/Hyperactivity Disorder (ADHD) is characterized primarily by challenges with maintaining attention, hyperactivity, and impulsivity. Individuals with ADHD often find it difficult to focus on tasks, may struggle to follow through on instructions, and frequently exhibit behaviors such as fidgeting or excessive movement that are not appropriate for the setting.

This set of symptoms sets ADHD apart from the other disorders mentioned. Autism Spectrum Disorder (ASD) involves a broader range of social, communication, and repetitive behavior challenges rather than focusing solely on attention and hyperactivity. Oppositional Defiant Disorder (ODD) is defined by a pattern of disobedient and hostile behavior toward authority figures and does not primarily include attention or hyperactivity issues. Learning Disabilities (LD) refer to difficulties in processing information or acquiring skills in academic areas but do not inherently involve the impulsive and hyperactive behaviors that define ADHD.
