You just met a client who herniated a disk after moving heavy boxes at work. What can you tell him about his prognosis?
- A.
He should expect ipsilateral paralysis and contralateral somatosensory loss
- B.
He will need surgery, but luckily herniated disks usually resolve within six weeks post-surgery
- C.
He should expect bilateral paralysis and ipsilateral somatosensory loss
- D.
There will likely be no need for surgery. The injury usually resolves itself within six weeks
Correct Answer
D. There will likely be no need for surgery. The injury usually resolves itself within six weeksExplanation
A herniated disk occurs when there is compression of a spinal disk on to the nerve root. Symptoms can include pain, numbness, and weakness. Generally, symptoms resolve without surgical intervention within six weeks.Rate this question:

Which of the following best describes Dementia?
- A.
A disorder seen in chronic alcoholism and severe malnutrition causing damage to the mammillary bodies
- B.
An age-related, progressive, irreversible brain disorder
- C.
A non-specific illness syndrome in which areas of cognition are impaired
- D.
The loss of long-term memory
- E.
None of the above
Correct Answer
C. A non-specific illness syndrome in which areas of cognition are impairedExplanation
Dementia, a non-specific illness syndrome in which areas of cognition are impaired, can affect problem solving, learning, memory, orientation, and judgment, among other things. Answer "A" describes Korsakov's syndrome. Answer "B" describes Alzheimer's disease. Answer "D" describes amnesia.Rate this question:

After a car accident, one of your clients has Brown-Sequard syndrome, which means that he has suffered a hemisection of his spinal cord. What would you expect to see in terms of his somatosensory functioning?
- A.
Contralateral loss of pain and temperature sensation
- B.
Ipsilateral paralysis
- C.
Ipsilateral loss of proprioception and discriminative touch
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
Because the STT tract decussates at the level of the spinal cord and the DCML tract decussates in the medulla, the loss of pain and temperature (STT) will be felt contralaterally, while the loss of proprioception and discriminative touch will be felt ipsilaterally. In addition, paralysis will occur ipsilaterally in every spinal cord injury.Rate this question:

If a client complained of dark or blurred central vision, what would you first suspect he or she might have?
- A.
Bilateral hemianopia
- B.
Macular degeneration
- C.
A spinal cord injury
- D.
Acoustic neuroma
Correct Answer
B. Macular degenerationExplanation
Macular degeneration occurs when the central vision is lost or impaired. Bilateral hemianopia would involve bilateral loss of the peripheral vision field. A spinal cord injury would not necessarily be accompanied by any vision problems. Acoustic neuroma would cause problems with hearing and balance, not vision.Rate this question:

Your client complains that although she has no visual impairments, she is unable to recognize familiar faces. You conclude that she must have alexia, a type of agnosia.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
You would conclude that your client had prosopagnosia, a type of agnosia that involves the inability to recognize familiar faces. Alexia, another type of agnosia, is the inability to comprehend written language. (Agnosia is a general term for the inability to recognize or make sense of incoming information despite intact sensory abilities.)Rate this question:

Spinal polio attacks which of the following neuroanatomical structures?
- A.
Basal ganglia
- B.
Upper motor neuron bodies
- C.
Brachial plexus
- D.
Lower motor neuron bodies
Correct Answer
D. Lower motor neuron bodiesExplanation
While bulbar polio attacks the central nervous system cell bodies, spinal polio attacks the lower motor neuron bodies. The basal ganglia and brachial plexus are not generally involved in polio.Rate this question:

Your client's wife is confused about what caused her husband's Alzheimer's and what is happening inside his brain. You tell her that while the cause of Alzheimer's is unknown, you can tell her a little about what neural mechanisms are at work during the course of the disease. Which of the following might you mention?
- A.
Neurofibrillary tangles caused by abnormal tau (a protein) in the neurons
- B.
Degeneration of dopamine-producing cells in the substantia nigra (part of the basal ganglia)
- C.
Neuritic plaques caused by extracellular deposits of amyloid (a fibrous protein) between neurons
- D.
Injury to the optic chiasm (the intersection of two hemiretinas)
- E.
Both A & C
Correct Answer
E. Both A & CExplanation
Answer "B" describes a cause of Parkinson's. Answer "D" describes an injury to the visual system. In addition to options "A" and "C," you might mention decreased ACh in the basal nucleus of the frontal lobe as another neural mechanism involved in Alzheimer's.Rate this question:

What is the etiology of Multiple Sclerosis?
- A.
Birth injury
- B.
Autoimmune
- C.
Virus
- D.
Amnesia
- E.
Unknown
Correct Answer
B. AutoimmuneExplanation
Multiple Sclerosis is an autoimmune disorder causing demyelination of the oligodendrocytes in the central nervous system.Rate this question:

One of your clients, an eight-year old boy, has Duchenne's Muscular Dystrophy (DMD). Which of the following symptoms would he be most likely to demonstrate?
- A.
Enlarged calf muscles
- B.
Ptosis
- C.
Gower's sign
- D.
Pounding headache
- E.
Both A & C
Correct Answer
E. Both A & CExplanation
DMD causes Gower's sign (occurring when a patient must use his or her arms and hands to "walk" up from a squatting position due to lack of lower extremity strength) as well as enlarged calf muscles (due to fatty deposits, not larger muscles). A pounding headache would be a symptom of autonomic dysreflexia. Ptosis, or drooping eyelids, would not be caused by DMD.Rate this question:

You ask your client to use a carrot scraper to peel a carrot. Instead, she appears to try to cut the carrot scraper with the carrot. What diagnosis might you suspect she has?
- A.
Ideomotor limb apraxia
- B.
Conceptual limb apraxia
- C.
Ideational limb apraxia
- D.
Dressing apraxia
Correct Answer
B. Conceptual limb apraxiaExplanation
Apraxia is defined as the inability to perform purposeful movement (in the absence of paralyis or paresis). It is most often caused by damage to the left hemisphere. In ideomotor limb apraxia, the patient is unable to carry out a motor command. In conceptual limb apraxia, the patient has difficulty using tools. In ideational limb apraxia, the patient is unable to create a plan for a specific movement and has difficulty sequencing. Dressing apaxia involves the inability to dress oneself.Rate this question:

A person with hydrocephalus suffers from blocked circulation of cerebrospinal fluid. Fortunately, this condition can sometimes be alleviated by the insertion of a shunt.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Hydrocephalus is a condition characterized by the blockage of cerebrospinal fluid circulation in the brain. This blockage can lead to an accumulation of fluid, causing increased pressure on the brain. Fortunately, one possible treatment for hydrocephalus is the insertion of a shunt. A shunt is a medical device that helps redirect the excess fluid to another part of the body, relieving the pressure on the brain. Therefore, the statement "A person with hydrocephalus suffers from blocked circulation of cerebrospinal fluid. Fortunately, this condition can sometimes be alleviated by the insertion of a shunt" is true.Rate this question:

Which of the following symptoms are most commonly associated with an upper motor neuron lesion?
- A.
Hyporeflexia
- B.
Hyperreflexia
- C.
Adductor spasms
- D.
Flu-like symptoms
Correct Answer
B. HyperreflexiaExplanation
Upper motor neuron lesions are often associated with hyperreflexia, hypertonicity, paralysis, paresis, hyperstiffness, and abnormal reflexes such as the Babinski reflex.Rate this question:

Your client has trouble with a complex perceptual function called figure ground discrimination. Which of the following activities might she have the most trouble with?
- A.
Moving through her living room without bumping into the coffee table
- B.
Discriminating between the left and right sides of her body
- C.
Picking out a black pen from a drawer full of other pens
- D.
Remembering the route from her house to her daughter's school
Correct Answer
C. Picking out a black pen from a drawer full of other pensExplanation
Your client would have trouble picking a black pen out of a drawer of other pens because figure ground discrimination allows us to differentiate foreground objects from background objects. She would have a hard time avoiding the coffee table if she had no spatial relations, and she would have difficulty discriminating between the left and right sides of her body if she had right/left discrimination problems. Remembering the route from her house to her daughter's school would require good topographical orientation.Rate this question:
