Abstract:
The case reported presents difficulties of interpretation of electroencephalographic recordings made on a patient lying on a fluidized bed. The moving silica grains in fluidized beds simulate pathological electrogenesis, giving diffuse slow-wave abnormalities or paroxysmal epileptiform activity. It is therefore essential that fluidized beds be switched off when recording electroencephalograms.
