Scales for the assessment of Alzheimer's disease.
The clinical symptoms of Alzheimer's disease must be assessed and characterized comprehensively to confirm a diagnosis of dementia, to follow the course of the illness, and to evaluate the effects of treatment. Comprehensive assessment measures are multi-item scales that evaluate the various core cognitive symptoms of dementia and that provide a total score representing the overall magnitude of cognitive impairment. Neuropsychologic test batteries provide more detailed, objective evaluations of the various cognitive functions that are impaired. Global staging methods provide a single measure of the stage or severity of dementia, which is useful for tracking the clinical course and for comparisons among different studies. Scales to assess activities of daily living (basic physical functions and more complex instrumental activities) provide the most clinically relevant information regarding a patient's capacity to function in daily life. Finally, noncognitive behavioral symptom scales evaluate the secondary dementia symptoms (depression, agitation, hallucinations, delusions, etc.) that provide the greatest difficulty for patient management.
