cognitive abilities screening instruments (CASI)

Advantages

• ease of administration
• relatively quick compared to full neuropsychological battery
• higher score range minimizes ceiling effect of MMSE
• examines several cognitive domains, provides domain scores
• more refined scoring system for pentagons
• translated versions for other languages retain contextual contexts & same total score range

Procedure

Combines items from MMSE, 3MS & Hasegawa Dementia Scale

• 25 items
• range of scores: 0-100
• test administration time: 15 minutes

Goals of instruments:

• screening instruments for dementia
• monitor of disease progression
• provide a profile of impairiment among differing domains of cognitive impairment

Domains examined:

• attention
• concentration/mental manipulation
• orientation
• short-term memory
• long-term memory
• language
• visual construction
• list fluency
• abstraction & judgement

Sensitivity: 91%*

Specificity: 95%*
