Neurological Disorders Flashcards
CRP/ESR
Lab for inflammation
Complex regional pain syndrome
Pain in extremity out of proportion to initial injury
Diagnosed by having 2 or more of the following: allodynia, vasomotor changes, sudomotor changes, edema, decreased ROM, trophic changes
Treatment of complex regional pain syndrome
PT/OT
NSAIDs, AEDs, topical antioxidants, Vitamin C
Nerve blocks, epidural/ intrathecal meds
Sympathectomy
Pain management team
Palliative care team
Hyped of primary headaches
Migraine
Cluster
Tension
Other(post exercise/ coital/ cough/ etc)
Detailed headache assessment
OLDCARTS
Headaches a month
Auras
Hormonal fluctuations
OLD CARTS
Onset, location, duration, characteristics, aggravating factors, relieving factors, treatments tried, severity
When to worry about headaches
WHoL- SAH
Thunderclap- aSAH
With vigorous exercise- perimesencephalic SAH
With fever/ stiff neck - Meningitis
New onset after 50yr- tumor
With known cancer- Mets
With neuro changes
Progressive and increasing
Objective HA assessment
Neuro exam
Temporal artery tenderness
Occipital nerve tenderness
TMJ tenderness
Episodic, disabling, and w or w/o aura
Diagnostic tests for HA
ESR/ CRP to rule out temporal arteritis
Imagine to r/o structural cause
CT, MRI, CTA, MRA, MRV
LP
Treatment of HA
Mild to moderate pain
NSAIDS, muscle relaxers, heat, cold,
massage, PT
Moderate to severe pain
Triptans, ergot alkaloids
Adjunctive: anti-emetics, IV
Diphenhydramine
Education
HA diary
Prevention
Overall self care
Medications
Beta blockers, antidepressants,
AEDs, Botox
Status migrainosis requirement and treatment
Disabling migraine lasting more than 72 hours
IV migraine cocktail- VPA,
Methlyprednisolone, Mag, ketorolac,
prochlorperazine, diphenhydramine
Hydrate
Cluster headaches requirements and treatment
Rapid onset and excruciating
Medications: IV or intranasal sumatriptan, IV diphenhydramine, lidocaine nose drops, O2 7L/min for 10 minutes max
Definition of seizure
Sudden, excessive electrical discharge of neurons altering brain function and producing electrophysiological changes
What is epilepsy
Repeated unprovoked seizures
Focal onset seizures
Excessive electrical activity limited to one area
Focal Onset Aware: no chance in
awareness
Focal Onset Impaired Awareness:
Clouding of consciousness, staring,
repetitive motor behaviors
(automatisms)
General onset seizures
Excessive electrical activity that encompasses the entire brain
May start as focal
Most common forms: Tonic-clonic,
absence seizures, myoclonic
Unprovoked causes of epilepsy
Genetics
Neurodegenerative dementia
Unknown in 30-50%
Provoked causes of seizures
Acute structural injury: SAH, trauma, encephalitis, tumor, ICH, cerebral anoxia
Remote structural injury: prior trauma, CP, AVM, perinatal cerebral ischemia
Metabolic: low glucose, magnesium, sodium, calcium; high glucose, hepatic encephalopathy, uremia
Withdrawal: AEDs, benzos, ETOH, barbs, medications
Subjective seizure assessment
Detailed history: antecedent event, description of seizure, alterations in consciousness, post-ictal state, current illnesses, past medical history, social history, med list, known epilepsy history
Diagnostic tests for epilepsy
EEG
cEEG
CT/MRI
Neurophysiological testing: sodium
amobarbital, stimulation with grids
Interventions for seizures
AEDs- monotherapy if possible
Medical- ketogenic diet
Surgical interventions: VNS, Corpus
Collosotomy, lobectomy
Education
Seizure journal
Self-care
Psychogenic non-epileptic seizures
Physical manifestation of a physiologic disturbance
Diagnosed with cEEG in EMU
20-30% patient in EMU
Interventions: be transparent with dx,
education, psychotherapy
Status epilepticus
Refers to single, uninterrupted seizure greater than 5 minutes or frequent clinical seizures without a return to baseline
Types: non-convulsive or convulsive
Both types are medical emergencies
Risks with convulsive status epilepticus
Arrhythmias, aspiration, hypercapnia, lactic acidosis, and fever from the stress of continuous muscular convulsions and intense neuronal activity
Interventions for status epilepticus
ABCs!!!!
Neuro assessment to classify type
Supportive ventilation
Initial meds: lorazepam 0.1mg/kg
Phenytoin: 20mg/kg @50mg/min
Fosphenytoin: 20mg PE/kg @100-120
pe/ min
If hypoglycemia is suspected: 100mg thiamine then 50cc of D50
Continue ABCs: intubate if needed
Treat metabolic abnormalities
Continuous EEG
Refractory infusions: midazolam,
propofol, pentobarbital
Super-refractory: ketogenic diet,
ketamine, ECT
Hydrocephalus
Results from an imbalance between CSF inflow and outflow
Caused by obstruction, inadequate absorption, or over production
Types of hydrocephalus
Congenital
Acquired: non-communicating, communicating, normal pressure
