Which of the following is NOT classified as a chronic neurodevelopment disorder?

Hearing impairment is classified as a sensory disability rather than a neurodevelopmental disorder. Chronic neurodevelopmental disorders typically involve the central nervous system and are characterized by developmental deficits that produce impairments in personal, social, academic, or occupational functioning.

Conditions such as Asperger’s Syndrome, Autism Spectrum Disorder, and Learning Disabilities are all related to the brain's development and cognitive functioning, which distinctly categorize them as neurodevelopmental disorders. In contrast, hearing impairment affects one's ability to perceive sound, which may influence communication and social interactions but does not stem from the central nervous system's developmental processes, thereby distinguishing it from the other options.
