NMS Final Flashcards
(200 cards)
What are the 2 types of episodic loss/lapse of consciousness?
Syncope and seizures.
What is the difference between syncope and seizures?
Syncope is due to global cerebral and or brainstem ischemia. Seizures are due to abnormal cerebral neuronal discharges.
What is the onset like for syncope and seizures?
Syncope is progressive onset of lightheadedness and in an upright posture usually. Seizures- sudden onset.
How will syncope and seizures end?
Syncope promt recovery. Seizure- postictal confusional state may follow.
Name some of the causes of seizures?
idiopathic (usually epilepsy), febrile convulsions (in kids with high body temps and are benign and haave no increase in risk of epilepsy, trauma, brain tumors, stroke, infections, metabolic.
What are the 2 general types of seizures?
Generalized and partial.
What are the generalized seizures like?
involve the entire brain, sudden onset and are usually bilateral and symmetrical. These have a high familial predisopistion and are usually benign.
What are partial seizures like?
Invovle a focal part of the brain, usually secondary to a disease or pathology and have a wide variety of symptoms.
What should be done with partial seizures?
They should be stereotyped.
What are the different types of generalized seizures?
- Tonic-clonic (grand mal). 2. Absence (petit mal). 3. Other (tonic, clonic, myoclonic, atonic- drop attacks).
What are tonic-clonic (gand mal) seizures like?
10-30 sec of tonic and then 30-60 sec of clonic (shaking) then 10-30 minutes of postictal confusional state.
What are absence (petit mal) seizures like?
loss of consciousness but not postural tone, momentary lapses of consiousness. They may become tonic-clonic.
What are the different types of partial seizures?
Simple and complex.
What are simple partial seizures like?
Similar to TIA. Consciousness is maintained and symptoms correlate to area of the brain seizing and can have motor, sensory, autonomic, psychic, auditory, olfactory, etc.
What are complex partial seizures like?
impairment of consciousness, but not loss. May have an aura that precedes it. Can have automatisms (involuntary motor activity like lip smacking or picking at a button).
What type of imaging should be done for someone with seizures?
MRI to find a treatable cause of the brain. EEG to look for classic abnormalities in brain.
What type of nutrition is recommended for someone with idiopathic generalized epilepsy?
no large meals, avoid alcohol and caffeine. Take vitamin E. Ketogenic diet.
What is a hydrocephalus?
An abnormal accumulation of CSF.
What are some causes of hydrocephalus?
may be idiopathic or secondary to meningitis, subarachnoid hemorrhage, or other pathologies.
What are the signs and symptoms of someone with hydrocephalus?
Weird, wet, wobbly. Dementia, slowing of movement, urinary incontinence, gait apraxia.
How will you diagnose hydrocuphalus?
MRI shows large ventricles without cortical atrophy. Lumbar puncture- may have normal or elevated opening pressure.
What are the signs and symptoms of a brain tumor?
Cognitive changes and HA are most common.
Name 2 hereditary causes of dementia?
Wilsons disease and huntingtons disease.
What is Wilson’s disease?
a disorder of copper metabolism which lets copper accumulate in the brain, basal ganglia, liver, cornea and kidney. IT IS THE ONLY DEMENTIA SEEN IN KIDS AND HAS AN ONSET OF AGE 11-19.
