Background– As the age of general population is raising the prevalence of vascular dementia (VaD) along with other dementias are also rising. VaD is the 2nd common form of dementia after Alzheimer‘s disease. There is no confirmatory test for dementia diagnosis. Many studies support the possibility for EEG to detect dementia in early stages by the use of EEG. Dementia in Creutzfeldt–Jakob disease has triphasic wave form in EEG as criteria for it diagnosis under ICD–10. Researchers are going for other types of dementias to make their diagnosis easy and affordable and cost effective. According to some studies EEG could be used as a diagnostic tool, as well as for predicting the stages of dementia as it can identify the neuronal activities and cognitive manifestation in dementia through techniques of EEG signal analysis and processing. Aims & Objectives– 1) To study EEG changes in vascular dementia. 2) Compare EEG changes in vascular dementia wit healthy controls. Material & Methods– forty vascular dementia participants and forty healthy elderly controls above age 55 years were included in this study. Participants 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. EEG were recorded in eyes closed, on intermittent photic stimulation and hyperventilation, and there data were entered in excel sheet and analyzed using SPSS Software, appropriate statistical test was applied wherever necessary. Results– participants with VaD have preponderance of theta wave as compare to control. Conclusion – EEG can have additive value in diagnosing VaD as well as it alone can be helpful in differentiating healthy individuals from dementia patients.
