Neuro-developmental disorders manifest during development and impair personal, social, academic, or occupational functioning. Let's examine the provided options:
- Autism Spectrum Disorder (ASD): A neuro-developmental disorder marked by challenges in social communication and interaction, alongside restricted, repetitive behaviors, interests, or activities.
- Intellectual Disability: This neuro-developmental disorder involves deficits in general mental abilities, affecting conceptual, social, and practical adaptive functioning.
- Specific Learning Disorder: Characterized by difficulties in acquiring or using specific academic skills such as reading, writing, or arithmetic, which are foundational for academic progress.
- Hallucinations: These are not neuro-developmental disorders but rather symptoms often associated with psychiatric conditions like schizophrenia.
- Conduct Disorder: This is categorized as a disruptive, impulse-control, and conduct disorder, not a neuro-developmental disorder. It involves behavior that infringes upon the rights of others or violates age-appropriate societal norms.
Consequently, options (A), (B), and (C) are the only ones classified as neuro-developmental disorders. The correct answer is: (A), (B) & (C) only.
