Overview
Most patients do not require a full neuropsychological examination as part of an evaluation for dementia; however, testing is useful when bedside cognitive testing is equivocal. Follow-up testing or just serial observations generally provide more helpful information than a single study, particularly when results are equivocal.[1]
Other Diagnostic Studies
Different diagnostic modalities used to make in diagnosis of dementias include:
- Genetic testing
- Cerebrospinal fluid (CSF) analysis is suggested in some cases
- Electroencephalogram (EEG) may be used to diagnose Creutzfeldt-Jakob disease or underlying metabolic/toxic disorders
- Lumber puncture
- Brain biopsy
- Positron emission tomography (PET)[2] [3]
- Single-photon emission computed tomography (SPECT)[4]
- VDRL
- HIV testing
