Overview

Limited laboratory testing is recommended in most patients being evaluated for cognitive impairment and dementia. We do not order other laboratory tests unless there is a specific suspicion for abnormality. Other than the routine lab work for dementia, other laboratory tests are not recommended unless there is a specific suspicion for abnormality.[1][2]

Laboratory Findings

Routine lab work for dementias include:

Electrolyte and Biomarker Studies
