Dementia Rating Scale-2
DRS-2; Mattis dementia rating scale
The Dementia Rating Scale-2 (DRS-2) is the most recent edition (2001) of a battery-style assessment of mental status in older patients with suspected dementia. The DRS-2 consists of 24 brief subtests whose scores are combined into five subscales of attention, initiation/perseveration, construction, conceptualization, and memory (for details, see Strauss et al. 2006). In addition to quantifying impairment in these specific cognitive domains, the sum of all five subscale scores (out of a possible total of 144 points) yields an estimate of overall dementia severity. As subtest items are arranged and administered in order of decreasing difficulty, patients who successfully complete the initial items on any subscale can be given credit for adequate performance on the entire subscale.
Historically, clinical cutoff scores were used to identify individuals with cognitive impairment. More recently, normative data for the DRS were...
