What are the symptoms of attention-deficit/hyperactivity disorder (ADHD) according to DSM-5?

The symptoms of attention-deficit/hyperactivity disorder (ADHD) as defined by the DSM-5 include inattention, hyperactivity, and impulsivity. This classification reflects the core characteristics of ADHD, where inattention can manifest as difficulty sustaining attention, organizing tasks, and following through on instructions. Hyperactivity may present as excessive fidgeting or an inability to remain seated or quiet when expected. Impulsivity often involves acting without considering the consequences, interrupting others, or struggling with waiting for one's turn.

In contrast, the other options describe symptoms associated with different mental health conditions. Memory loss and depression are more aligned with mood disorders or cognitive impairments rather than ADHD. Social withdrawal and anxiety typically relate to anxiety disorders rather than the behavioral symptoms found in ADHD. Delusions and hallucinations are indicative of psychotic disorders, not ADHD. Recognizing these defining symptoms is essential for accurate diagnosis and appropriate intervention strategies for individuals with ADHD.
