Examination of cognition and mental status in patients with suspected DLB may include the following findings:

  • Impaired, but relatively conserved cognition

  • Fluctuating cognition: Periods of being alert, coherent, and oriented alternating with periods during which the patient is confused and unresponsive to questions

  • Retrieval from memory: May be relatively worse than memory storage

  • May do relatively well with confrontation naming tests but poorly on tests of visuospatial skills (eg, drawing a clock, copying figures)
