how reliable is an eeg?

VAGUELY ACCURATE: An EEG is a recording of brain electrical activity taken over the scalp, over about 45 minutes. This brief period may completely miss many paroxysmal events and provide a false negative/normal result. Work with direct electrodes implanted into brain have convincingly demonstrated far more pathology than external recordings. So, basically "hit or miss" issues, and better to clinically assess.

ENG or VNG: Ear nose and throat doctors, neurologists, and audiologists can do an ENG or VNG for this. An EEG or brain wave test may help but is usually normal.
