Question | Answer |
when are EEG's useful | when looking for evidence of epilepsy. when trying to tell if a shaking episode is epilepsy. when attempting to determine if someone is consious or not. somewhat useful in detecting the absence of brain activity. |
not all spikes are __ | epileptic |
patients with seizures can have __ | normal EEG's |
manifested primarily in children and are a brief cessation of conversation or activity followed by immediate return of normal function, usually no shaking occurs | absence seizures |
a very characteristic EEG pattern often occurs intermittently even when the individual is not having an __ | absence seizure |
is an ongoing seizure which has little if any movement associated with it, the patients are poorly responsive but the etiology is unclear | Non-convulsive status epilepticus |
if a person has a focal seizure they are likely to develop additional seizures because the seizure is due to some __ | focal lesion |
if after a single seizure the patient has signs of epileptiform discharges on __, then they are likely to go on to have further seizures | EEG |
if after a single seizure the patient is found to have some sort of structural brain lesion on __, then they are more likely to have further seizures | MRI |
an episode which clinically looks like a seizure but occurs for emotional or psychological reasons and is not accompanied by EEG evidence of seizure during the episode | pseudoseizures |
__ do not respond to epilepsy medication | pseudoseizures |
prior to sophisticated imaging procedures EEG was useful in locating mass lesions as the EEG would be __ over the mass | muted or slow |
the EEG is quite useful in demonstrating the presence and degree of __ but rarely suggests the etiology | coma or encephalopathy |
if the EEG is completely flat-no evidence of brain activity, this is a useful adjunct in determining brain death. Brain death remains a __ | clinical diagnosis based on the neurological examination |
there are patients who meet criteria for brain death who __ | still have some EEG activity |
a needle is inserted into a muscle and the electrical activity of the muscle is observed during rest and activation. The activity is different if the nerve or muscle has been injured | electromyography |
the EMG/NCV should be considered an extension of the __ | neurologic examination |
are potentially useful whenever there is a suspicion of peripheral nerve or muscle injury | EMB/NCV |
they are particularly useful for detecting carpal tunnel syndrome | EMG/NCV |
they are very useful when investigating the presence or severity of polyneuropathy and sometimes suggest etiologies | EMG/NCV |
they are sometimes useful when investigating radiculopathy or muscle diseases | EMG/NCV |
electrical studies used to study the conduction of central nervous system pathways | Evoked Potential Studies |
electrodes are place on the scalp and brain potentials are recorded in response to a stimulus-measuring the size and timing of the response and comparing those results to normal values | Evoked Potential Studies |
