Background: Early detection of dementia is currently of great interest and of
crucial importance for the implementation of preventive measures and treatment
of the disease. Impairment in verbal episodic memory, and in particular in a
delayed recall phase, is considered one of the early markers of progression
from mild cognitive impairment (MCI) to dementia. Therefore, having cognitive
screening instruments with predictive value for progression is of utmost
importance. Objective:The purpose of this work is
to show the predictive value, sensitivity and specificity of the Memory
Impairment Screen with delayed recall (MIS-DR) to predict conversion to
dementia in patients with MCI. Methods:In retrospective study 502 patients over 60 years old, evaluated in the
Older Adult Functional Evaluation Unit of our hospital for cognitive complaint, were diagnosed with MCI. They were followed up to assess conversion to
dementia. Results: During follow up, 144 participants developed dementia
(28.6%, 95% CI 24.76-32.85) and the average time of progression to dementia were 23 months (SD 13.2).The cut-off point was
established below 6 for MIS-DR and it showed a sensitivity of 76% (95% CI 68.77-77.84) and a specificity of 56% (95% CI 50.44-61.58), with a positive predictive value of 41% (95% CI 34.78-47.6) and a negative predictive value of 85% (95% CI 80.53-
