Hyperactivity is a symptom that can be associated with several mental disorders, but it is not a disorder in and of itself.
Hyperactivity can be a characteristic of attention-deficit/hyperactivity disorder (ADHD), which is a neurodevelopmental disorder that affects both children and adults. ADHD is characterized by symptoms such as inattention, impulsivity, and hyperactivity.
Hyperactivity can also be a symptom of other mental health conditions, such as bipolar disorder, anxiety disorders, and some personality disorders.
Therefore, hyperactivity is not a mental disorder on its own, but it can be a symptom of various mental health conditions. A professional evaluation is needed to determine the underlying cause of hyperactivity and any related symptoms.
