Like other types of nuclear explosion, the explosion of a hydrogen bomb creates an extremely hot zone near its center. In this zone, because of the high temperature, nearly all of the matter present is vaporized to form a gas at extremely high pressure.
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.
EEG is a safe test with no side effects. However, a person with epilepsy may experience a seizure, triggered by the various stimuli used in the procedure, including the flashing lights. (This is not seen as a 'complication' by medical staff, because a seizure during an EEG can greatly help in diagnosis.)
