ADHD is defined by difficulties with attention, hyperactivity, and impulsivity. Inattentiveness shows up as trouble sustaining focus, easily missing details, and being easily distracted. Impulsivity appears as acting without thinking, interrupting others, and having difficulty waiting turns. Restlessness is part of hyperactivity—fidgeting, leaving seat, or speaking out of turn in situations where staying still is expected. Visual hallucinations, on the other hand, are not a characteristic of ADHD; they are more commonly associated with psychotic disorders, substance effects, or other medical conditions. So the statement that involves visual hallucinations does not fit ADHD’s typical symptom pattern.
