Abstract
Diagnosis of dementia remains probabilistic and difficult to retain. Noninvasive and inexpensive tools are needed for guiding the diagnosis. Use of electroencephalogram (EEG) in dementia has been the subject of several studies. We selected controls and patients with cognitive impairment. Clinical examination and neuropsychological evaluation was made for all subjects. A cerebral Magnetic resonance imaging (MRI) and biological investigations were also made. Additionally, all subjects had a wake EEG with visual analyses and scores calculating. Ninety two patients were included (66 patients and 26 controls). After Clinical, neuropsychological, biological and radiological data collection, we classified patients: 16 with mild cognitive impairment, 50 with dementia classified as follows: 24 with Alzheimer disease, 9 with vascular dementia, 5 with dementia with lewy bodies, 5 with fronto-temporal dementia, 5 with mixt dementia and 2 with Parkinson disease. A Grand total score inferior to 5 was in favor of psychiatric cause. A score superior to 5 was in favor of an objective cognitive impairment. Appreciation of reactivity by score 3 allowed to make difference between mild cognitive impairment and dementia.
