Answer

Patients with DLB may have changes on electroencephalography earlier than do patients with Alzheimer disease, but whether this difference is diagnostically useful is not clear.

In certain circumstances, neuropsychological testing is helpful in differentiating DLB from Alzheimer disease and in establishing a baseline for future comparison. [14]
