Neuro: Chart Cases (L) Flashcards
What visual system complications may arise from Parkinson’s Disease?
Impairments in color vision and contrast sensitivity. Difficulty with higher-level depth perception. Poor blink rate - dry eye.
Will Parkinson’s Disease create any pupillary control deficits,pupillary asymmetry, pupillary dilation, light reflex accommodation-induced constriction?
Most likely no, but it is still possible.
Is papilledema likely in a patient with Parkinson’s Disease?
Unlikely.
What oculomotor deficits may occur in Parkinson’s Disease?
Fragmented saccades, reduced accuracy, and increased latency.
What mental status deficits, cranial nerve deficits, or motor system deficits may be present in Parkinson’s Disease?
Typically 3 main motor issues: Bradykinesia, resting tremor, rigidity (cogwheel).
Patients do not have weakness or reflex changes.
Difficulty with attention and speed of mental processing or problem solving. Memory and language difficulties.
What should be expected as a patient with Parkinson’s Disease enters the clinic?
Slowed movement and overall issues with moving in a smooth manner.
How does levodopa treat Parkinson’s Disease?
By replacing dopamine.
What are common side effects of levodopa?
Nausea, dizziness, headache. Motor fluctuations.
Could carbidopa and L-dopa side effects alter vision in Parkinson’s Disease?
Possible to see some slight abnormal eye movements.
Will Huntington’s Disease involve any complications for the visual system?
Unlikely to see any major visual field deficits or blurred vision.
Will Huntington’s Disease create any pupillary control deficits?
Unlikely.
Is papilledema likely in a patient with Huntington’s Disease?
Unlikely.
What oculomotor deficits may occur in Huntington’s Disease?
Slowing of saccadic movements.
What mental status deficits may be present in Huntington’s Disease?
Irritable and aggressive behavior.
Difficulty in recognizing the look on a person’s face.
Tongue darting.
Over time problems may get worse/more deteriorating.
What should be expected as a patient with Huntington’s Disease enters the clinic?
Movement with difficulty sitting still.
Will a recent stroke of the inferior part of the internal capsule create any pupillary control deficits?(ACA)
No.
Is papilledema likely in a patient with a recent stroke of the inferior part of the internal capsule?(ACA)
No.
Could a recent stroke of the ACA involve any oculomotor deficits?
It could affect eye movements since the FEF and other eye fields send axons through the Internal Capsule.
What should be expected as a patient with a recent stroke of the ACA enters the clinic?
Patient showing abnormal gait/movement.
What new neurological deficits could a patient recovering from a stroke display?
Possible to notice athetosis.
What movement issues are associated with athetosis?
Slow, writhing involuntary movements.
