1. The development of multiple cognitive deficits manifested by both

   1. memory impairment (impaired ability to learn new information or to recall previously learned information)
   2. one (or more) of the following cognitive disturbances:
      1. aphasia (language disturbance)
      2. apraxia (impaired ability to carry out motor activities despite intact motor function)
      3. agnosia (failure to recognize or identify objects despite intact sensory function)
      4. disturbance in executive functioning (i.e., planning, organizing, sequencing, abstracting)
2. The cognitive deficits in Criteria A1 and A2 each cause significant impairment in social or occupational functioning and represent a significant decline from a previous level of functioning.
3. The deficits do not occur exclusively during the course of a delirium and persist beyond the usual duration of substance intoxication or withdrawal.
4. There is evidence from the history, physical examination, or laboratory findings that the deficits are etiologically related to the persisting effects of substance use (e.g., a drug of abuse, a medication).
