Background: With significant increases in life expectancy the number of person with dementia are also climbing. There is no confirmatory test to diagnose dementia. Doctors diagnose dementia based on a medical history, a physical examination, and the characteristic changes in thinking, day-to-day function and behavior. Certain diagnosis of dementia is only possible after post-mortem exam. Efforts are being made to diagnose these neurodegenerative disorders in the early stages.

Aims & Objectives: 1) Aim: - To study Diagnosis capability of EEG in dementia.

 2) To study EEG changes in different parts of brain by using 32 channels, 24 lead EEG machine.

Material & Methods: The study was conducted by including patients and healthy elderly controls above age 55 years. Subjects were taken from Dept of psychiatry, MGM Medical College and MYH, Indore fulfilling the inclusion and exclusion criteria. Written informed consent will be taken after explaining the objectives and procedure of study in detail. The EEG of participants has been recorded in Mental Hospital Banganga by using departmental RMS® EEG Systems Maximus version 4.2.54. © 2007-2008. Data were entered in excel sheet and analyzed using SPSS Software, appropriate statistical test was applied wherever necessary.

Results: Participants with dementia have slow waves preponderance as compare to control.

Conclusion: EEG can be used to differentiate person with dementia with healthy individual.
