Overview

EEG is a test of cerebral function, it indicates any generalized or focal dysfunction of brain. Generalized slowing of EEG waves is seen in diffuse encephalopathies. It helps in differentiating in epileptiform encephalopathies and epilepsy conditions.

Electroencephalogram

• Generalized slowing - diffuse encephalopathies
• Generalized periodic epileptiform discharges
• Low voltage activity is seen all over the brain
• Triphasic waves can be seen in few cases
