Disruption that can occur from vestibular apparatus (inner ear) through the cranial nerve to the CNS where the information is processed Any disruption along this path will cause a vestibular disorder Anatomy Peripheral vestibular system BPPV: problems within the vestibular apparatus, specifically semicircular canal Creates sensation of moving,...

Episode 19: Central Cord Syndrome Host Jimmy McKay Featured guest Bridget Ripa Notes Alexis Lancaster What is it? Damage to the central portion of the spinal cord How does it happen? Hyperextension of the cervical spine is the typical cause Inflammation or pressure on the cord centrally Anatomy/Presentation Tricky Damages spinothalamic, corticospinal, and dorsal columns Upper extremities weaker than lower extremities Greater motor deficits than sensory deficits The sensation of the sacral...

Episode 18: Brown Sequard Syndrome Notes by Alexis Lancaster, SPT What is it? Damage to one side of the spinal cord Mechanism of injury: MVA, gunshot wound, stab wound Impairments/presentation: Ipsilateral losses: proprioception, vibration, deep touch, discriminative touch, and voluntary motor control Contralateral losses: pain, temperature, crude touch Differential diagnosis: Other spinal cord injuries (see above impairments list and differentiate this way) MS Spinal infarct Spinal tumor...

15 – Neuro – Autonomic Dysreflexia

8/20/2018
More
Episode 15- Autonomic Dysreflexia What is it? Excessive autonomic nervous system activity triggered by afferent stimuli below the level of the spinal cord injury (usually level T6 and above) The stimulus can be noxious or non-noxious Usually it is a noxious stimulus Example: kinked catheter, tight clothing, overheating, UTI, bowel impaction, skin irritation Need to realize that the patient does not have sensation at this level, so their body is telling them that something is wrong via...

More
Episode 14: Huntington’s Disease Host Jimmy McKay Featured guest Bridget Ripa Notes by Alexis Lancaster What is it? Inherited, an autosomal dominant trait Causes degeneration to specific brain regions Huntington’s disease gene is on chromosome 4 and it produces the Huntington protein that’s found throughout the body Signs/Symptoms Symptoms can present at any age Symptoms can include physical, cognitive, and psychiatric signs & symptoms The disease is divided into 5 stages Preclinical, early,...

11 – Neuro – TIA

8/17/2018
More
TIA – Transient Ischemic Attack Notes by Nick O'Hanlon, SPT What is it? The same underlying mechanism as an ischemic stroke; with the main difference being the duration of symptoms is significantly less In other words, a brief episode of neurological dysfunction caused by ischemia (lack of blood supply) to the brain No tissue death occurs Signs and Symptoms Clinically presents like a stroke, but can also look like: a seizure disorder, tumor, migraines, or hypoglycemia Stroke symptoms –...

Episode 9: Heterotopic ossification (HO) featured guest Bridget Ripa Notes by Alexis Lancaster What is it? The formation of bone inside soft tissue structures, where it’s not supposed to be It is extra-articular, so it occurs outside of the joint capsule What is involved? How does it happen? Exact pathophysiology is unknown Usually comes from a period of immobilization or traumatic injury to that bone or to the affected area of the body Presentation Swelling, redness, warm to the touch...
