Indications

* also see cognitive assessment

Diagnostic criteria

Clinical significance

Procedure

* free tools validated in primary care populations[10]

# MMSE may be better than MoCA for cognitive screening in African American patients

# MoCA is better than MMSE for detecting MCI in the elderly, particularly in the oldest old population[12][13]

Radiology

* presence of 2 of 3 predicts dementia

* hippocampal atrophy associated with 5-fold risk

* white matter lesions associated with ~3-fold risk[8]

Management

  • insufficient evidence to recommend for or against screening[1]
  • screening best postponed until effective therapy available[4]
  • consider screening for all older adults, despite lack of effective treatment[2]
    • actually 2-5% of cases are due to reversible causes[3]
    • early warnings could avoid problems with
    • driving
    • financial mismanagement
    • social isolation
  • screening of nursing home residents for dementia does not reduce emergency department transfers[20]
  • a healthy diet, adequate sleep, & exercise should be part of recommendations for every patient, regardless of cognitive complaints[6]
