Population-Based Study of Medical Comorbidity in Early Dementia and “Cognitive Impairment, No Dementia (CIND)”: Association With Functional and Cognitive Impairment: The Cache County Study

Persons with CIND and dementia have more serious medical comorbidity than comparable persons without cognitive impairment. This comorbidity may play a role in the progression of CIND and dementia. Future studies should investigate the role of medical comorbidity and its treatment on dementia onset or progression, as well as the mechanisms mediating its neuropathologic effects.
