14 Cards in this Set

  • Front

The basal ganglia affect frontal lobe functioning via:

a. indirect projections through the thalamus and related nuclei

b. indirect projections through the cerebellum

c. direct projections to frontal cortex

d. diffuse cortical projections
a. indirect projections through the thalamus and related nuclei
Turner's Syndrome is characterized by all of the following except:

a. preserved nonverbal skills

b. one missing chromosome

c. high intra-uterine mortality

d. underdeveloped sex organs
a. preserved nonverbal skills
Asperger's Disorder resembles Autistic Disorder execept that in the former condition:

a. language development is usually much closer to normal patterns

b. there are usually no major impairments of social interaction

c. repetitive and stereotyped behaviors typically do not occur

d. the onset of symptoms is usually after the age of 10 years
a. language development is usually much closer to normal patterns
Landau-Kleffner Syndrome involves predominantly:

a. global aphasia

b. visual agnosia

c. motor apraxia

d. optic ataxia
a. global aphasia

A rare, childhood neurological syndrome characterized by the sudden or gradual development of aphasia and an abnormal electroencephalogram (EEG). LKS affects the parts of the brain that control comprehension and speech. The disorder usually occurs in children between the ages of 5 and 7 years.
Which of the following two vascular structures ar the only two UNPAIRED vessels in the Circle of Willis?

a. superior cerebellar artery and the anterior communicating artery

b. posterior cerebellar artery and posterior communicating artery

c. anterior communicating artery and posterior communicating artery

d. basilar artery and anterior communicating artery

e. basilar artery and posterior communicating artery
d. basilar artery and anterior communicating artery
The WADA test in epilepsy surgery candidates is used to:

a. determine language dominance

b. establish the adequacy of memory in the non-involved hemisphere

c. contribue to determining seizure laterality by the disparity in memory performance between hemispheres

d. all of the above
d. all of the above

Often, in patients with medial temporal lobe epilepsy, injection of the contralateral hemisphere causes severe memory difficulties.

In patients with normal bilateral medical tmeporal memory function, injection of one hemisphere does not eliminate memory, since the other hemisphere can compensate.
The anterior and dorsomedial nuclei of teh thalamus obtain their blood perfusion primarily from:

a. polar and parmedian arteries

b. lenticulostriate arteries

c. deep penetrators throug the anterior performated substance

d. recurrent artery of Heubner
a. polar and parmedian arteries

Recurrent artery of Heubner - supplies the anteroinferior portion of the head of the caudate nucleus, the putamen and the anterior limb of the internal capsule

Lenticulostriate arteries - supplies the outer segment of the globus pallidus and the putamen, th superior half of the internal capsule, the adjacent corona radiata, and much of the caudate nucleus.
Pallidotomy for refractory Parkinson's Disease has been shown to have the most dramatic improvement in:

a. tremor

b. rigidity

c. gait

d. pseudobulbar affect
b. rigidity

A lesion is placed stereotactically in the ventral posterior portion of the globus pallidus. The lesion interrupts the inhibitory output pathway carried by the ansa lenticularis from the medial globus pallidus to the ventral lateral nucleus of the thalamus.
Which of the following reliably differentiates patients with epileptic seizures from patienst with pseudoseizures?

a. urination during seizure

b. MMPI-2 Scale 3 score within normal limits

c. cognitive test scores in impaired range

d. none of the above
d. none of the above

The only true reliable way to differentiate between the two is that pseudoseizures are not associated with abnormal, rhythmic discharges of cortical neurons.
Chronic alcoholics may develop Wernicke's encephalopathy as the result of:

a. thiamine deficiency

b. liver failure

c. neurotoxic effects of alcohol

d. malabsorption of electrolytes
a. thiamine deficiency
Lesions of the cerebellar hemisphere cause which of the following signs?

a. ataxic movement ipsilateral to the lesion

b. paresis ipsilateral to the lesion

c. ataxic movement contralateral to the lesion

d. spasticity contralateral to the lesion
a. ataxic movement ipsilateral to the lesion
The transcortical aphasias are distinguished from the other forms of aphasia by:

a. preserved repetition

b. defective phonemic discrimination

c. preserved visual naming

d. defective tactile naming
a. preserved repetition
Patients who have had complete sectioning of the corpus callosum cannot:

a. read material presented in the left visual field

b. name objects presented in the right visual field

c. identify a letter of the alphabet drawn on their right hand

d. reliably report right-ear stimuli during dichotic word listening
a. read material presented in the left visual field
Gait ataxia, urinary incontinence, and acute confusion (or dementia) is the classic syptom triad of:

a. normal pressure hydrocephalus

b. Parkinson's disease

c. lateral medullary syndrome

d. progressive suprnuclear palsy (PSP)
a. normal pressure hydrocephalus
