Peripheral nerve basics
This is the mildest type of peripheral nerve injury and usually resolves without surgery
Neuropraxia
This progressive disorder involves both upper and lower motor neuron degeneration
ALS
Amyotrophic Lateral Sclerosis
this movement disorderpresents with resting tremor, rigidity, bradykinesia, and postural instability
Parkinson Disease
this metabolic disorder commonly causes peripheral neuropathy, especially in the feet
Diabetes
A patient presents with rapid onset of symmetrical weakness beginning distally, following a recent respiratory or GI illness
Guillain Barre Syndrome
This term describes degeneration of the diatal axon after a nerve injury
Wallerian Degenerations
This demyelinating disease which can affect the CNStoo, often presents with relapses and remissions
MS
Multiple Sclerosis
This inherited disorder causes progressive ataxia due to the degeneration of the cerebellum and spinal cord
Friedrich's Ataxia
Charcot-Marie-Tooth disease primarily affects this structure of the PNS
Myelin Sheath
Injury to this nerve may result in a Claw Hand Deformity
Ulnar Nerve
Peripheral nerve regrowth occurs approximately how much per day?
1 mm
Decline in this cognitive function is the hallmark feature of Alzheimer Disease
Memory
this enetic disease causes involuntary choreiform movements and cognitive decline
Huntington's Disease (Huntington's Chorea)
Patients with post polio syndrome commonly experience these symptoms years after recovery
New or worsening muscle weakness
Damage to this nerve may cause loss of thumb opposition
Median nerve
Name one clinical sign commonly seen in Lower motor neuron lesions
muscle atrophy
muscle fasciculations
decreased or absent reflexes
hypotonia
Name a risk factor associated with Alzheimers
age, family history, genetics, head trauma
Parkinson disease is primarily associated with deficiency of this neurotransmitter
Dopamine
Diabetic neuropathy commonly presents with this pattern of sensory loss
stocking glove
distal to proximal
The most common symptom seen with a radial nerve injury is?
Wrist drop
wrist extensor weakness
This type of cell produces Myelin in the Peripheral Nervous System
Schwann Cells
Damage to the upper motor neurons in ALS may produce this reflex abnormality
hyperreflexia or spasticity
Name one early motor symptom commonly seen in Friedrich's ataxia
gait ataxia
dysarthria
loss of propriocepton
Facial nerve
Compression of the median nerve at the wrist results in this common condition
Carpal Tunnel Syndrome
