Summary
Electroencephalography (EEG) can help diagnose dementia, especially rare conditions like SSPE and CJD. Quantitative EEG shows promise as an additional diagnostic tool for various dementing illnesses.
Area of Science:
- Neurology
- Neurophysiology
Background:
- Dementia is a global health issue with diverse causes, including neurodegenerative diseases and infections.
- Distinguishing between dementia types can be challenging due to overlapping symptoms.
Purpose of the Study:
- To review the role of electroencephalography (EEG) in diagnosing various dementing illnesses.
- To explore the utility of quantitative EEG as a diagnostic aid.
Main Methods:
- Systematic literature search of PubMed and Cochrane Database (1946-2016).
- Keywords included "EEG," "electroencephalography," "dementia," and "status epilepticus."
- Qualitative and quantitative EEG findings in dementia were summarized.
Main Results:
- Specific EEG patterns are characteristic of certain dementias, such as subacute sclerosing panencephalitis (SSPE) and Creutzfeldt-Jakob disease (CJD).
- Quantitative EEG analysis is emerging as a valuable tool to complement traditional diagnostic methods.
Conclusions:
- EEG is a valuable neurophysiological tool for diagnosing specific dementia syndromes.
- Quantitative EEG offers potential for improved diagnostic accuracy in dementia evaluation.
