Final answer:
The DSM-5 categorizes conditions such as autistic disorder, Asperger's disorder, childhood disintegrative disorder, and pervasive developmental disorders under Neurodevelopmental Disorders.
Step-by-step explanation:
According to the DSM-5, the category that previously included autistic disorder, Asperger's disorder, childhood disintegrative disorder, and pervasive developmental disorders is now named Neurodevelopmental Disorders. This change reflects the understanding that these conditions have a common feature of being disorders that occur when the development of the nervous system is disturbed. Within this category, disorders such as autism spectrum disorder and attention deficit/hyperactivity disorder are included due to their complex symptoms that affect communication, learning, social skills, and the motor system.
