Quickly Make Decisions About Your Dementia Client's Mental Status and ADLs


Patients with neurocognitive impairment (e.g., dementia) are often unreliable reporters of their own symptoms. A knowledgeable observer such as a family member, friend, or home health nurse, can provide valuable insight into a patient's functioning, including ADLs. The OACS is a quick informant rating scale that helps professionals make decisions about a patient's mental status and determine the need for more in-depth testing.

Features and benefits

  • The only screening tool that maps directly onto the six principal domains of neurocognitive function defined in the DSM-5-TR : executive function, complex attention, language, perceptual–motor, social cognition, and learning and memory. 
  • Assesses activities of daily living separately from total neurocognitive impairment.
  • All-digital format ensures safe and convenient access to informant raters. 
  • Quickly indicates the need for follow-up testing.
  • Administer and score in less than 10 minutes via PARiConnect. 
  • OACS Change Report tracks change over time.
