Which condition is commonly associated with symptoms that include inattention and hyperactivity?

Attention-Deficit/Hyperactivity Disorder (ADHD) is a condition that is distinctly characterized by symptoms of inattention and hyperactivity. Individuals with ADHD may struggle to focus on tasks, tend to be easily distracted, and may display impulsive behavior. The hallmark features that define ADHD make it a primary condition associated with these symptoms.

In contrast, narcolepsy primarily involves uncontrollable sleep attacks and excessive daytime sleepiness rather than the hyperactivity or inattentiveness typical of ADHD. Anxiety disorders can lead to concentration difficulties due to excessive worrying or panic, but they do not typically include hyperactive symptoms. Insomnia mainly refers to difficulties in falling asleep or staying asleep, which would not directly cause inattention and hyperactivity. Therefore, ADHD is the most relevant condition associated with both inattention and hyperactivity symptoms.
