most common cause of seizure in adults over 60?
|
Stroke
2nd: malignancy |
|
Difference btw Primary and 2ndary seizure?
|
1: seizures recurring without consistent provocation or cause
2: response to certain toxic, metabolic, or environmental events |
|
Difference btw generalized and partial seizures?
|
Gen: both cerebral hemispheres and is accompanied by LOSS OF CONSCIOUSNESS (grand mal or absence)
Partial: one cerebral hemisphere; consciousness either maintained (simple partial) or abnormal consciousness (complex partial) |
|
difference btw simple and complex seizures
|
consciousness either maintained (simple)
abnormal consciousness (complex) |
|
define status epilepticus
|
abnormal electrical activity for more than 5 minutes
can be any kind of seizure unlikely to terminate spontaneously |
|

herpes encephalitits
|
|
given the following history or exam finding give the potential seizure red flag:
hypertension, tachycardia, piloerection |

|
|
recurrent seizures without a return to consciousness is another definition for...
|
status epilepticus
|
|
leading cause of adult onset epilepsy in areas such as Latin America, Asia, Africa
|

prolonged tonic clonic seizures can lead to what MSK problem
|
posterior should dislocation
|
|
anisocoria suggests what?
|
impending herniation through the foramen magnum
(unequal pupils) |
|
automatisms (repetitive actions such as lip smacking, swallowing, or chewing) are frequent in what kind of seizure?
|
complex partial
|
|
what is Todd's paralysis
if present what might it suggest |
postictal paralysis
following seizure weakenss of one extremity or complete hemiparesis can last up to 24 hours higher likelihood of underlying structural cause for seizure (look for a cause) |
|
given the following signs/sx give the diagnosis:
usually brought on by anger, fear, frustation. Pallor or cyanotic spells, apnea or bradycardia normal neuro exam |
Breath-holding spells in infants
EEG during spells |
|
given the following signs/sx give the diagnosis:
tongue deviation, torticollis, jerking random limb movements, lvl of consciousness usually maintained |
Extrapyramidal reactions
look for specific meds |
|
given the following signs/sx give the diagnosis:
shortness of breath followed by paresthesias, carpopedal spasm and LOC increased respiratory rate, normal neuro exam |
Hyperventillation syndrome
|
|
given the following signs/sx give the diagnosis:
may closely mimic sx of true seizure, often in the setting of emotional distress usually quick return to normal mental status post event |
Psychogenic seizures
continuous EEG monitoring during events |
|
given the following signs/sx give the diagnosis:
sudden onset of weakness, difficulty speaking, or walking abnormal neuro findings |
TIA/CVA
head CT, ECG, labs |
|
given the following signs/sx give the diagnosis:
brief twitching movements; classic prodrome includes lightheadedness, tunnel vision no post ictal state, no tongue biting |
Vasovagal syncope
ECG, glucose testing |
