Concomitant AD pathology affects clinical manifestation and survival in dementia with Lewy bodies

DLB-patients with a CSF AD profile have a more severe manifestation of the disease and a higher risk of institutionalisation and mortality. In clinical practice, CSF biomarkers may aid in predicting prognosis in DLB. In addition, DLB-patients with positive AD biomarkers could benefit from future treatment targeting AD pathology.
