Summary

In the current study, the investigators will examine the extent of subclinical epileptic activity in patients with Alzheimer's disease and patients with Lewy body dementia as compared to healthy elderly controls. The participants will wear a new device called "ear-EEG", which makes it possible to record EEG for longer periods of time while at home. Furthermore, the investigators want to investigate whether there is an association between subclinical epileptic activity and the cerebral blood flow as measured with functional MRI.
