An adolescent is being observed for atention deficit hyperactivity disorder (ADHD). Which circumstance would demonstrate evidence to support this diagnosis?

Choice A reason: Multiple motor and vocal tics are more indicative of Tourete syndrome, not autism spectrum disorder.
Choice B reason: Overly atached behavior is not typically associated with autism spectrum disorder; individuals with ASD may struggle with social atachments.
Choice C reason: This is the correct choice. Individuals with autism spectrum disorder often display a preference for solitary activities and may have difficulty forming friendships.
Choice D reason: An irresistible urge to pull out one's hair is characteristic of trichotillomania, not autism spectrum
disorder.

Choice A reason: Medication is not a defining feature of all mental illnesses. While medications can be a part of treatment for many psychiatric conditions, not all mental illnesses require medication. Some may be managed with psychotherapy, lifestyle changes, or other non-pharmacological interventions.

Choice B reason: Self-awareness or acknowledgment of difficulties is not a prerequisite for a mental illness diagnosis. Many individuals may not realize they have a mental health condition, especially in cases of severe mental illness or when insight is affected.

Choice C reason: The presence of difficulties in functioning that cause significant distress or impairment is a core aspect of mental illness. These difficulties can manifest in various areas such as social, work, or family activities, and are a key factor in diagnosing mental health conditions.

Choice D reason: While physiological symptoms can accompany certain mental health conditions, they are not a defining feature of all mental illnesses. Mental illness primarily involves significant changes in thinking, emotion, and/or behavior.
