Making Better Predictions about Symptoms and Progression of Illness
Once obtaining a diagnosis of a form of cognitive impairment likely due to Alzheimer’s disease or Frontotemporal Lobar Degeneration or a related disorder, most individuals want to talk about prognosis and treatment. We have performed a large body of work examining the use of various clinical or imaging measures to predict the progression of cognitive decline or behavioral symptoms. Results have shown that—at least for groups of patients—the rate of decline can be predicted by a combination of the severity of cognitive symptoms as they affect a person in daily life and a person’s difficulties performing cognitive tests in the clinic or lab. In addition, MRI measures of brain shrinkage or changes in function are useful for prediction.
