Flashcards in diseases, problems whatever Deck (21):
1

disconnection syndrome

caused by disconnection of the corpus callosum

2

tay-sachs disease

genetic abnnormality from gangliosides; muscle weakness, blindness, seizueres, death

3

paralysis agitans

parkinson's; trouble initiating voluntary movement; loss of inhibitory control over basal ganglia

4

ataxia

distubrance of balance that may lieave the person unable to stand without help; problem affecting the cerebellum

5

dysmetria

inability to stop a movement at a precise point or time; may lead to an intention tremor; reflects cerebellar dysfunction

6

babinski sign

a spinal reflex in infants; fanning of the toes produced by stroking hte fot on the side of the sole; in adults this is a sign of cns injury

7

hyperreflexia

exaggerated reflex response

8

spinal shock

severe injury to the spinal cord that produces a period of sensory and motor paralysis; may or may not be temporary

9

spinal transection

completly severed

10

spinal concussion

violent jolts or blows, sometimes associated with trauma or gunshot wounds; produces a period of spinal shock but symptoms are only temporary;

11

spinal contusion

hemorrhages in the meninges; has the ability to gradually recover over a period of a few weeks, but full functonality may not be restored

12

glioblastoma multiforme

most common and fatal type

13

meningioma

benign noninvasive tumor of falx and convexity of hemisphere

14

schwannoma

benign peripheral tumor from schwann cells

15

ependymoma

found in ventricles and spinalcord gliomas

16

medulloblastoma

ponsterior fossa tumor, seen in children and can metastasize through csf tracts

17

symp. of transection of lateral spinothalamic tract

contralateral loss of pain and temp below the lesion

18

symp and definition of Brown sequard syndrome

imcomplete hemisection of the spinal cord that results in ipsilateral hemiplegia with contralateral loss of pain and temperature; loss of tactile, position and vibration sensation

19

symp. of transection of corticospinal tract

spastic paresis with pyramidal signs like babinski sign

20

amayotrophic lateral sclerosis

damage to corticospinal gtracts with pyramidal signs, damage to LMNs, usually no sensory deficits

21

neurosyphilis

loss of tactile discrimination, position, vibration sensation. if the person puts their feet together and closes their eyes, they fall over
