Met criteria for partial remission after initial episode of full remission
Met full criteria for ADHD after initial episode of full remission
Recurrence could not be judged when remission solely occurred at final time point
Demonstrated full remission of ADHD, followed by partial or full recurrence, followed by a second episode of full remission (i.e., ADHD, full Remission, Recurrence, full Remission).
Recovery was defined as full remission that persisted for at least two consecutive assessments without being followed by a recurrence (includes both first episodes of remission or recurrent episodes that meet this criteria). Eight cases that were classified as recovered experienced full remission followed by partial or full recurrence, and finally a second period of full remission that led to recovery, whereas 42 experienced no recurrence after the initial episode of full remission.
