Case 7: Dementia Syndrome (MCI Index = 4)

This mixed dementia syndrome case is from a 77-year-old retired computer systems analyst with a three-year history of visual "hallucinations" or misperceptions and memory problems.  His wife expressed concern about his daily alcohol use.

A score of 11 out of 12 falls within the average range.
A score of 8 out of 8 falls within the average range.
The Comprehension subtest score indicates an inability to consistently perform two-step commands. In the absence of hearing impairment or significant problems with attention, this suggests an acquired language impairment that should be further evaluated.
A score of 1 out of 6 indicates severe spatial-construction disability that needs to be further evaluated both medically and cognitively. Although spatial-construction ability varies widely in the normal population, this score indicates moderate to severe spatial-construction disability.
A score of 10 out of 12 falls within the average range for patients of this age.
This patient has specific areas of impairment: Comprehension, Constructions, Calculations.
MCI Index: 
The MCI Index is 4, which raises the question of a Mixed Dementia Syndrome and is likely to impact occupational and social functioning. This patient should be further evaluated for treatable causes of cognitive decline.
The patient was consistently unable to perform two-step tasks and thus scores on the other Cognistat subtests must be interpreted with caution.
