Study Notes
Screening Tools for Cognition and Mood in Older Adults
- A "gold standard" test is one that is most likely to correctly identify people with a condition and those who do not have the condition.
MMSE (Mini-Mental State Examination)
- A brief tool used to systematically assess mental status
- Assess five areas of cognitive function: orientation, registration, attention, calculation, and recall and language
- Takes 5-10 minutes to complete
- Maximum score is 30, and a score of 23 or lower indicates cognitive impairment
- Sensitivity of 92-98% and specificity of above 70%
AD8 (Eight-item Informant Interview to Differentiate Aging and Dementia)
- A brief screening tool used to help discriminate between the signs of normal aging and mild dementia
- Tests memory, orientation, judgment, and function
- Can be completed in-person or over the phone
- Takes approximately 3 minutes to perform
- Sensitivity > 84% and specificity > 80%
MoCA (Montreal Cognitive Assessment)
- A tool for early detection of mild cognitive impairment
- Used in primary and secondary care settings
- Assess eight cognitive domains: attention and concentration, executive functions, memory, language, visuoconstructional skills, conceptual thinking, calculations, and orientation
- Takes approximately 10 minutes to complete
- Highly accurate, correctly identifying dementia about 94% of the time
ACE-III (Addenbrooke's Cognitive Examination III)
- A screening tool used to detect cognitive impairment, especially Alzheimer's disease and fronto-temporal dementia
- Assesses five cognitive domains: attention/orientation, memory, language, verbal fluency, and visuospatial skills
- Takes up to 20 minutes to complete
- Useful tool for clinicians to assist in making a dementia diagnosis
Geriatric Depression Scale (GDS)
- Designed for the assessment of depression in elderly people
- Used in community and acute and long-term care settings
- Short-form GDS takes about 5-7 minutes to complete, and long-form GDS takes around 15 minutes
- Found to have a 92% sensitivity and an 89% specificity when evaluated against diagnostic criteria
Cornell Scale for Depression in Dementia (CSDD)
- Developed to assess major depression in patients with dementia
- Designed as a screening tool, not diagnostic
- Used to assess moderate to severely impaired older people with dementia
- Takes approximately 30 minutes to complete
- Valid screening tool for depression in older people with dementia, with a sensitivity and specificity of 93% and 97%
