Jim is a 68 y/o man just placed on your caseload at UW-Madison Hospital. You find out he is 10 days status-post CVA, and decide to visit him in his room on your way to see another patient. Upon entering his room, it is evident that he has deficits in attention and executive function. After talking with Jim and his wife, you notice there is still food on the left side of his plate, yet the right side is completely clean. What is the most likely diagnosis for Jim? Describe the meaning of the diagnosis (i.e. symptoms). Where would you have expected this CVA to occur?
Left neglect; he lost the left side of the world both visually AND conceptually; right hemispheric lesion

True or False? The extrapyramidal system has direct output to LMN's.
FALSE! The pyramidal system has direct output to LMN's.

Deterioration/degradation of the substantia nigra results in ______________.
Parkinson's disease
300
Both the ______________ and _______________ decussate at the spinal cord.
lateral spinothalamic tract; anterior spinothalamic tract

John is a 64 year old male complaining of "odd vision" at the emergency room. When asked to describe when the symptoms first occurred, he says he lost his peripheral vision one day while driving. He feels as though he has tunnel vision. Since that day, he still is unable to see peripherally. You tell John and his wife that he most likely has a lesion on his ________ _________ which is causing __________ __________.
optic chiasm lesion w/ bitemporal hemianopia

Melany is a 48 y/o woman recently admitted to the hospital. She has been labeled a fall risk, because she will get up out of bed without any assistance. When she gets up, she bumps into things, almost as if she can't see them. Despite running into things every time she gets up, she claims that "I [she] can see!!!!" Upon reading her chart, you discover she has bilateral lesions on her primary visual cortex. What is her diagnosis?
cortical blindness
300
What well-known disease occurs as a result of damage to the substantia nigra of the basal ganglia? What are some common MOTORIC deficits associated with this disease?
Parkinson's disease; resting tremor, bradykinesia, atypical gait (Parkinsonian gait)
300
What part(s) of the cerebellum is NOT visible from a dorsal view? (hint: it has a weird but cool but long name!)
Flocculonodular lobe
400
Describe the type of sensation correlated with the following somatosensory pathways: 1) Lateral Spinothalamic tract 2) Posterior Columns 3) Which of these pathways decussates at midbrain?
1) Pain & Temperature 2) Proprioception and fine touch 3) NEITHER! LST decussates @ spinal cord; posterior columns decussate @ medulla
400
The __________ ____________ ___________ of the thalamus is associated with the visual system.
Lateral Geniculate Nucleus (LGN)
400
Describe visual ataxia and visual agnosia including both symptom(s) AND lesion site
Visual ataxia--person sees frame by frame; lesion on the dorsal stream of the visual association areas Visual agnosia--person can see objects, but can't identify them; lesion on the ventral stream of the visual association areas
400
What is the significance of the primary motor cortex? SMA? Premotor area?
Voluntary movement; internal cues; external cues (selection of movements based on events)
400
The lateral portion of the cerebellum is responsible for ______________ planning.
motor

Makenna complains of "clumsiness" of her left leg due to an absent sensation of where the limb is in space. She presents with typical ROM and muscle strength. When presented with stimuli on her right leg, she can discriminate light vs. hard poking, cold vs. hot temperatures, and a two point touch; however, none of these sensations, EXCEPT discrimination of temperature, are present on her left leg. Proprioception deficits noted when she is unable to accurately perform movements asked of her. Damage to what system is causing Makenna's symptoms?
Dorsal column
500
Describe the visual field cut associated with the following lesion sites: 1) Optic nerve 2) Optic radiations
1) left or right visual field cut (monocular blindness) 2) homonymous hemianopia OR quadrantanopia

As the PRN SLP at a local hospital you only work weekends, and therefore, you aren't familiar with the families of your patients. Your first patient of the day, Mike, is a man who is 9 days status-post CVA. His CT scan reveals the stroke occurred in the parietal lobe, but seems to be very localized to a small area. Halfway through your therapy session, a woman enters the room and greets the patient. You wait for a response from Mike, but hear nothing. You realize Mike looks very confused and seems to be unfamiliar with who he is seeing. After saying hi again, Mike responds "Hi. Who are you?" Your memory from neuro with Dr. Mayer is triggered, and you realize Mike most likely has _____________.
Prosopagnosia

The middle cerebellar peduncle's major function is input from spinal cord? True or False--if false, correct the statement
FALSE! The middle cerebellar peduncle's major function is input from cortex!

Ida is an 84 year old woman recently admitted to the hospital post-CVA. You are asked to perform a brief evaluation on Ida to determine if she is eligible for speech/language services. Before going to see her, you review her CT scan and find the Radiologist noted a lesion to the cerebellar vermis. Based on your newfound knowledge of the cerebellum, specifically the vermis, what do you expect her motor deficits to be? She might have concomitant cerebellar __________ as a result of her stroke (hint: think of the clinical word for incoordination!).
Difficulty with maintaining balance and posture; cerebellar ataxia
