1

What is myelopathy?

pathology of the spinal cord

2

What is Brown-Sequard Syndrome?

unique spinal cord pathology where there is:
-loss of pain, temp and light touch on opposite side of the damage
-loss of motor function, vibration, position, and deep touch sensation on the same side of the damage

3

What is the hallmark of encephalopathy?

impaired intellectual functioning

4

What are the symptoms of encephalopathy?

-interferes with normal daily activities
-loss of ability to solve problems
-may have loss of emotional control, seizures, loss of motor control, loss of vision

5

What are the types of encephalopathy?

1) temporary (metabolic, medication, etc.)

2) permanent (traumatic)

6

What is Alzheimer Disease?

from loss of smell, to lapses in judgment and subtle personality changes, to loss of ability to perform simple activities of daily living, to bed dependent. A Progressive Encephalopathy.

7

What is Huntington Disease?

-progressive autosomal dominant disease;
-Encephalopathy manifested by personality changes, movement disorder, gait disturbance, to bedridden and death approximately 15 years after symptoms manifested (begin age 30-40).

8

What is Rett Syndrome?

-a genetic disorder almost exclusive to females; (XX vs. male XY).
-Genetic but not inherited.
-first 12-18 months ok, then progressive deterioration of memory, movements, coordination, communication, seizures.

9

What is the biochemistry of Rett Syndrome?

-Locus coeruleus affected;
-doesn’t produce
Norepinephrine;
-so distribution to cerebral cortex,
hippocampus, cerebellum affected;
-Results in bi hemispheric
diffuse brain dysfunction

10

What are the functions of the right hemisphere?

-abstractions
-creativeness
-spatial sense

11

What are the functions of the left hemisphere?

-lingual
-academic
-reasoning

12

What are the functions of the frontal lobes?

-planning
-behavioral/impulse control
-personality
-social/sexual behavior

13

Which lobe is primarily concerned with motor function?

posterior aspect of the frontal lobes

14

What are the functions of the temporal lobes?

-processing auditory info
-comprehension of meaningful speech
-memory
-visual object recognition
-long term storage of sensory input

15

What is the dominant side of the temporal lobes?

-usually left side
-word perception
-processing details
-memory
-auditory learning
-complex memories
-visual/auditory processing

16

What is the non-dominant side of the temporal lobes?

-usually right side
-perception of melodies
-facial expressions
-visual learning

17

What is the function of the parietal lobe?

-processing of sensory info of touch
-affects opposite side
-taste
-temp
-language processing/integration

18

What is apraxia?

-An inability to carry out a task despite understanding the command
-having the motor function and the will to do so
-usually involves left parietal lobe

19

What is the function of the occipital lobes?

-primary visual cortex

20

What is agnosia?

inability to process sensory information (touch, visual, auditory, movement)

21

What is the subcortex/subcortical?

the area of the brain below the cerebral cortex; below the cerebral hemispheres

22

What are structures of the subcortical structures?

-limbic system
-hippocampus
-thalamus
-hypothalamus
-cerebellum
-midbrain
-pons
-medulla

23

What is the dorsal columns tract and where does it cross the spinal cord?

-vibration/position
-deep touch
-cross at low medulla

24

What is the corticospinal tract and where does it cross the spinal cord?

-motor
-cross at low medulla

25

What is the spinothalamic tract and where does it cross the spinal cord?

-pain
-temperature
-cross near level of lesion

26

Where is the main disorder iwth Myasthenia Gravis?

myoneural (neuromuscular) junction
