David's symptoms of being excitable, impulsive, very active, and having difficulty concentrating all point towards attention-deficit/hyperactivity disorder (ADHD). Mental retardation and childhood schizophrenia have a different set of symptoms and are not indicated here. A sensory deficit involves impairment in one or more of the senses, which is not described in the scenario.
