Case 9: Dementia Syndrome (MCI Index = 5)

This 82-year-old woman presented with a five-year history of gradually increasing problems with memory.  Neurologic examination was unremarkable and a full battery of neurodiagnostic tests for treatable causes of dementia was negative.  Cognistat revealed multiple areas of intellectual dysfunction in a pattern typical of mild to moderate Alzheimer Dementia.

A score of 6 out of 12 indicates significant disorientation. This may reflect significant confusion and/or memory impairment but other possibilities include aphasia and psychosis. It is important to rule out possible medication side effects.
A score of 8 out of 8 falls within the average range.
The Comprehension and Naming subtest scores strongly indicate acquired language impairment with a substantial weakness in Naming that can represent an isolated language disorder or can occur in the context of generalized cognitive impairment. Further medical and cognitive evaluation is indicated.
A score of 0 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 5 out of 12 indicates significant memory impairment. It is important to rule out treatable causes of memory problems and/or more general cognitive decline. This patient needs to be further evaluated both medically and cognitively.
This patient has specific areas of impairment: Orientation, Repetition, Naming, Constructions, Memory, Calculations, Similarities.
MCI Index: 
The MCI Index of 5 suggests a Mixed Dementia Syndrome that is likely to impact occupational and social functioning. This patient should be further evaluated for treatable causes of cognitive decline.
The patient required multiple presentations in order to register the four words for the Memory Subtest and thus scores on the other Cognistat subtests must be interpreted with caution.
