Neuro/Psych 4 Flashcards
Simple seizures
Focal (1 hemisphere)
- No LOC/postictal state
- Motor, sensory, autonomic, or psychic sx
Tx: narrow spectrum
Complex seizures
Focal (1 hemisphere)
- LOC and postictal state
- May have automatisms (e.g. lip smacking)
Tx: narrow spectrum
Tonic-clonic
Generalized (both hemis)
- LOC and Postictal state
- Diffuse muscle contraction (tonic) — then rhythmic jerking (clonic)
Tx: Broad spectrum
Myoclonic seizures
Generalized
- No LOC or postictal state
- Brief jerking movements
Tx: broad spectrum
Absence seizures
Generalized
- Brief LOC (blank stare)
- May have automatisms (e.g. lip smacking)
- Usually no postictal state
Tx: ethosuximide
What are narrow spectrum tx for seizures?
Carbamazepine
Gabapentin
Phenobarbital
Phenytoin
What are broad spectrum tx for seizures?
Lamotrigine
Levetiracetam
Topiramate
Valproic acid
Tx for bulimia nervosa
- SSRIs
- Nutritional rehab
- CBT
Why is buproprion contraindicated in someone with bulimia?
Elevated risk of seizures
MOA of carbamazepine
Blocks VG-Na channels in cortical neurons
Stabilizes these channels in an inactivated state => fewer Na channels
Adverse effects of carbamazepine?
- Bone marrow suppression => anemia, agranulocytosis, thrombocytopenia
- Hepatoxic
- SIADH
Get LFTs and CBC periodically
Which tx are used in AD?
- Cholinesterase inhibitors (Donepezil)
- Antioxidants (Vit E)
- NMDA receptor antagonists (Memantine)
Clinical features of OCD?
Obsessions:
- Recurrent, intrusive, anxiety-provoking thoughts, urges, images
Compulsions
- Response to obsessions w/repeated behaviors
- Behaviors not connected realistically w/ preventing feared event
Time-consuming (>1h/day)
Subdural hematoma on a CT scan
Crescent-shaped
Rupture of cortical bridging veins
Subdural hematoma clinical signs
- ^ed ICP (BP)
Young pts:
- Gradual onset of HA and confusion
- think MVA, bad fall
Elderly:
- Minor trauma
- Variety of neuro sx (gait, seizures, somnolence, confusion, memory loss)
