Q

Parkinson’s disease true

A

Gradual progression
Good response to L dopa
Gait Instability starts later
asymmetrical onset
Resting tremor

18
Q

Diseases like Parkinson’s, parkinsonism

A

rapid progression
Poor response to L dopa
Early symptoms of falling, dementia, hallucinations
Often have a symmetrical onset
MSA autonomic nervous system, blood pressure, respiration, bladder functions

19
Q

Utricle

A

Oriented horizontally
Detect head movement in horizontal plane
walking falling forward

Lateral vestibulospinal tract

20
Q

saccule

A

oriented vertically
Detect vertical displacement of the body
riding in an elevator, jumping up and down

Lateral vestibulospinal tract

21
Q

semi circular canals

A

detect the movement of the head on the body
Angular acceleration

Head bobbing spinning in a circle

Medial vestibulo spinal tract

22
Q

Asia scale-A

A

complete
no sensory or motor function at S4/5

23
Q

asia scale b

A

sensory incomplete

sensory but no motor function at S4/5

24
Q

Asia scale C

A

Motor incomplete

More than half of muscles below the neurological level of injury have a grade less than three

25
Q

Asia scale D

A

Motor incomplete

Half or more of key muscles below the neurological level of injury have a grade greater than or equal to three

26
Q

Asia scale E

A

Normal

27
Q

More Gray matter in which area

A

sacral

white matter- cervical

28
Q

where is more gray matter?

A

Sacral

Cervical has more white matter

29
Q

weber test

A

poorer ear- tone referred to this ear indicates conductive hearing loss

better ear- tone referred to this ear indicates perceptive impairment

30
Q

rinne test

A

normal- air conduction is twice as long as bone conduction

Conductive loss - bone conduction longer or equal to air conduction

Receptive- air conduction longer than bone conductions both variably shortened

31
Q

upper motor neuron lesion on the right

A

Patient can wrinkle forehead on both sides, but lacks the ability to keep the left eye closed

lower face affected, but the upper will be preserved

32
Q

lesion on left facial nerve

A

Both upper and lower face will be affected on that side

33
Q

place a vibrating tuning fork on the vertex of a persons cranium the sound is louder on the right side

A

Conductive hearing loss on the right
