P300 long-latency auditory EPs have been considered for using in evaluation for Alzheimer disease. In Alzheimer disease, the posterior scalp components are selectively lost. This test was also found to be strongly correlated with hypometabolism on positron emission tomography in this disease population. Although the test shows promise, its findings are considered nonspecific and nondiagnostic and are not limited to Alzheimer dementia. [38]
