Seizure
|
abnormal excessive or synchronous neuronal activity in the brain. Pt presents w/ involuntary changes in awareness/behavior
|
|
Partial Seizure
|
Seizure that originates in a localized part of the cerebral cortex, that involves motor, sensory, autonomic, or psychic symptoms. May or may not progress to a generalized seizure
|
|
Generalized Seizure
|
seizure (as an absence seizure or tonic-clonic seizure) that originates in both cerebral hemispheres
|
|
Absence Seizure (Petit Mal)
|
a nonconvulsive generalized seizure marked by the transient impairment or loss of consciousness usually with a blank stare, that begins and ends abruptly and is usually unremembered afterward. **decline in school performance may be clue
|
|
Simple Seizure
|
consciousness is not impaired; may have tingling, visual changes, focal motor or autonomic sx
|
|
Complex Seizure
|
consciousness is impaired
|
|
Tonic Clonic Seizure (Grand Mal)
|
generalized seizure that is initially tonic and then becomes clonic and is characterized by the abrupt loss of consciousness
|
|
Tonic phase
|
abrupt LOC following epileptic cry; muscles tense, pt falls
|
|
Clonic phase
|
dramatic muscle contraction/relaxation
|
|
Epilepsy
|
group of disorders marked by abnormal electrical discharges in the brain and typically manifested by sudden brief episodes of altered or diminished consciousness, involuntary movements, or convulsions
|
|
Temporal Lobe Epilepsy
|
partial seizures that originate in the temporal lobe and are marked by impairment of consciousness, automatisms, unusual changes in behavior, and hallucinations (as of odors)
|
|
Lennox-Gastraut Syndrome
|
seen in kids 2-18; variety of generalized seizures, developmental delay
|
|
juvenile myoclonic epilepsy
|
otherwise healthy teen/young adult has myoclonic jerks early in am. Triggered by sleep deprivation. Need lifelong AED, avoidance of triggers
|
|
epilepsy demographics
|
most common in kids 0-14 (genetics, congenital anomaly, trauma, neoplasm), risk decreases until age 60 (vascular dz, neoplasm, trauma, infection, neurodegeneration)
|
|
Status Epilepticus
|
Seizure lasting > 30 minutes. The seizure may be continuous or intermittent without recovery of consciousness between episodes. Neurological emergency with a mortality rate greater than 20%.
|
|
Syncopy
|
Transient LOC and postural tone for few seconds to few minutes with prompt recovery
|
|
vasodepressor syncopy
|
due to excessive vagal tone or impaired reflex ctl of peripheral circ. Most common type. Initiated by stress,. Premonitory nausea, sweating, pallor, tachycardia
|
|
dx vasodepressor
|
characteristic hx is present, carotid sinus massage or tilt table test
|
|
Orthostatic
|
due to impaired vasoconstrictive response to upright posture >> abrupt decrease in venous return.
|
|
who gets orthostatic syncopy
|
advanced age, DM, hypovolemia, vasodilator/diuretic/adrenergic blocker therapy
|
|
dx orthostatic
|
>20mm Hg dip in BP on standing, tilt table/valsalva are dx
|
|
cardiogenic
|
due to rhythm disturbances like sick sinus syndrome, AV block or aortic/pulmonic stenosis. Often exertional
|
|
cardiogenic dx
|
echo to r/o mechanical cause; EEG monitor
|
|
making diagnoses in general
|
cause not always found; do tilt table test before invasive studies
|
|
treating vasodepressor
|
avoid inciter, lie down, beta blocker
|
|
treating orthostatic
|
stop offending drug, stand up slowly,
|
|
treating cardiogenic
|
treat underlying issue; permanent pacer or implantable ICD
|
