what does an eeg test for?
An EEG can be used to help diagnose and assess several conditions that affect the brain, particularly epilepsy (a condition that causes seizures). Some of the other conditions for which doctors may want to perform an EEG include: 1  head injury; 2  brain tumour; 3  encephalitis (inflammation of the brain); 4  stroke; or.
Using an electroencephalogram (EEG) â a test that measures electrical activity in the brain â researchers are able to tell whether a person with attention-deficit hyperactivity disorder (ADHD) has the inattentive or hyperactive subtype, according to a new study published in the journal Biological Psychiatry.
