PNS-GBS-Cranial Nerves Flashcards
(36 cards)
Peripheral Neuropathy
general term for functional degeneration or pathological changes of the peripheral nervous system
(ie damage or impairment to peripheral nerves)
PN: symptoms
Start in fingers and toes and move up
Can move slowly or quickly
Paraesthesia
Spontaneous sensations of burning, cold, pins and needles or tingling
Dysaesthesia
Experiencing unusual sensations by touching or other stimulation
Anaesthesia
Lack of or diminished sensation
Hypoaesthesia
Diminished sensation
Types of sensory loss
Stocking and glove (sensations feel like a stocking or glove)
Loss of Position (don’t know where hands or feet are)
Motor Symptoms of PN
Weakness
Muscle cramps
Fasciculation (small muscle bundles contracting quickly)
Most common etiology
Diabetes and alcoholism
Most often cause is unknown
Diabetes PN
Can be slowed but not cured
Happens in all types
Starts in feet
Can cause non healing lesions
Alcohol PN
Can be reversed
From toxins in blood
Tricyclic Antidepressants (TCAs)
Chronic forms of pain
Used for PN of deep, burning feeling
Neurotonin
- Anti Siezure
- relieve PN pain
- Strong side effects
Pyridoxine (B6)
- nutritional support following PN
- up to 250 mg a day
Anti-oxidants
- Eliminate toxins which may cause PN
- Improve sx by uptaking glucose
Guillian Barre Syndrome
- acute, ascending and progressive PN characterized by poor reflexes and paraesthesia
- less severe than MS
- most common cause of acute/ sub acute paralysis
- happens over several days
GBS- etyology
Unknown
Believed to be immune related
-2/3 patients have GI issues weeks before
GBS- pathopysiology
Mylens rather than axons
Recovery depends on how fast mylens can be reconstructed
GBS- presentation
Ascending pattern of progressive, symmetrical weakness staring in lower extremities
- deep tendon reflexes are diminished
GBS- diagnosis
Nerve conductive studies (slower) Spinal Tap (High CFS protiens
GBS- treatment
Hospitalization a must!
Need to be on breathing and feeding tubs
Intraveneous Immunoglobin
Plasmapherisis
GBS- prognosis
Usually at weakest by 2 weaks (90% by three)
Recovery anywhere from a few weeks to a few years
Most recover with a few retaining weakness
Trigeminal Neuralgia
Characterized by shooting pain across face accompanied by a tic
Diagnosed by symptoms (no definitive test)
Not long lasting, a few times a day
Carbamazepine
anti- convulsant
- treats grand mal seizures, bi polar disorder, and TN
