Question | Answer |
Define seizure. | A seizure is an abnormal, unregulated paroxysmal electrical discharge in the brain that occurs within cortical grey matter and transiently interrupts normal brain function. |
Define epilepsy. | A chronic brain d/o characterized by recurrent >2 unprovoked seizures. Mostly idiopathic but may be due to stroke,tumors. |
Nonepileptic seizure | Provoked by a temporary d/o or any factors (metabolic, cardiovascular, CNS infection) |
Symptomatic seizure | Are mostly symptomatic as in neonatal seizure/in elderly |
Psychogenic seizure | Pts with psychiatric d/o simulate seizure with no abnormal electrical activity. Unresponsiveness is very common. |
Your explanation of an 85 yr old patient's seizure is due to___ or ____ | stroke, tumor |
Etiology of an adult seizure | Trauma, tumor, alcohol withdrawal |
"I'm sorry but your <24 month old is having this seizure because......." | developmental defects, metabolic d/o, birth injuries |
Focal seizure vs Generalized seizure | Focal-limited to one cerebral hemisphere/usually associated with structural abnormalities of the brain. Gen-across both cerebral hemispheres/may result from cellular, biochemical, or structural abnormalities that have a more widespread distribution. |
Clinical features of complex partial seizure | Preceded by an aura, impaired consciousness, but aware of surroundings so pt withdraws from noxious agents, limb automatism, utterance of unintelligible sounds w/o understanding what they say, head/eye deviation contralateral to the seizure foci,etc. |
Complex partial seizure can arise from any location in the brain but most commonly (60%) arise in the________ lobe | temporal |
Left temporal lobe seizures can cause...? | visual spatial memory abnormalities |
What are some causes of CPS? | Most often: Idiopathic Causes include:hippocampal sclerosis, neoplasm, cortical or vascular malformations, stroke Others:CNS infection, hypoxia to brain, head trauma |
Clinical manifestations of a focal seizure w/o LOC | Focal seizures can cause motor, sensory, autonomic, or psychic symptoms without impairment of cognition. Motor:Convulsive jerking somatosensory:paresthesia Sensory:light flashes or buzzing Autonomic:sweating, flushing, pupillary dilation |
What radiological test is diagnostic for focal seizures? | EEG |
What is the 1 drug that CAN NOT be used to treat focal seizures? | ETHOSUXIMIDE |
Why do you give your obese patient Topamax for her focal seizures? | Topamax side effect-weight loss |
The elementary school teacher noticed that your 6 year old is "daydreaming" A LOT. What type of seizure is occurring? | Typical Absence Seizure |
What is Lennox-Gastaut Syndrome? | severe form of epilepsy. Seizures begin before 4 years of age.children experience some degree of impaired intellectual functioning along with developmental delays, and behavioral disturbances.Causes:brain malformations, perinatal asphyxia,head injury |
What technique can you do in the clinic to diagnose and absence seizure? | in typical absence seizure, the physical and neurological findings are normal. having the child hyperventilate for 3-5 mins. often provoke absence seizures. this procedure can easily be performed in the clinic or office and the result is diagnostic. |
What is the most useful clinical feature differentiating absence from cps? | the most useful clinical feature distinguishing absence seizure from cps is the abrupt ending of typical absence seizures w/o postictal phase. |
What do you see on EEG for typical and atypical absence seizure? | in typical absence seizures, the EEG is usually regular and symmetrical, about 2-4Hz spike and slow wave complexes. In atypical absence seizure the EEG is more heterogenous and may include irregular spike and slow wave complexes, fast activity etc. |
The only diagnostic test for absence seizures is ? | EEG |
The only two first line AEDs approved for treating absence seizures are___and ____ | ethosuximide and valproic acid |
