The Consortium to Establish a Registry for Alzheimer's Disease (CERAD). Part X. Neuropathology confirmation of the clinical diagnosis of Alzheimer's disease.
This report summarizes the neuropathologic findings in the first 106 autopsies of CERAD (Consortium to Establish a Registry for Alzheimer's Disease) dementia patients diagnosed clinically as having Alzheimer's disease (AD). In 92 (87%) of the 106 cases, neuropathologists confirmed Alzheimer's disease (AD) as the primary dementing illness. Coexistent Parkinson's disease (PD) changes were present in 19 (21%) and vascular lesions of varying nature and size in 26 (28%) of these 92 AD cases. The 14 cases in which AD was not interpreted as the primary dementing illness can be divided into four major subgroups based on their neuropathology findings: PD and related pathology (n = 5), hippocampal sclerosis (n = 3), miscellaneous neurodegenerative and other disorders (n = 3), and no significant changes (n = 3). Despite the relatively high level of clinical diagnostic accuracy, further refinement of assessment batteries may facilitate distinction of non-AD dementias from AD.
