Q

What are the abnormal movements a result of?

A

failure to inhibit cortical motor discharges
also might be firing from the thalamus that isn’t inhibited causing these movements.
also be caused by an imbalance btwn excitatory and inhibitory neurotransmitters (ACH/Dopamine)

Q

what is myoclonus

A

myoclonus is single involuntary brief movements of a body part-like a jerk. Can be rhythmic or not–person cannot stop them. can be spontaneous or brought on by certain stimuli (one such stimuli is voluntary movements themselves) may occur in epilepsy.

A

from the cortex to the spinal cord.

31
Q

32
Q

what are tics?

A

they are rapid, patterned movements under partial voluntary control. The person may have some voluntary control over them.

33
Q

T or F when a person has tics–there is usually a strong, irrepressible urge to do these but the person may be able to control them for a while.

A

True

34
Q

T or F tics can range from simple tics that may look like myoclonus and dystonia but tics can be complex like (jumping up, making noises, lip smacking)

A

True

35
Q

what is chorea?

A

rapid involuntary and random purposeless movements of a part of the body, it is nonrhythmic and random. Can be present at rest and in voluntary movements. Can be subtle or severe.

36
Q

What is a type of chorea?

A

Huntington’s chorea (progressive and genetic)

37
Q

What is ballism?

A

abrupt contraction of muscles of the limbs-so bad the person can fall down (large muscle contractions not fine ones)

38
Q

what is athetosis?

A

inability to keep a body part in one position. it is slow writhing purposeless motion it is one type of Cerebral palsy.

39
Q

What is dystonia?

A

it is a slow hyerkinesias exhibited by involuntary postures due to problems with antagonistic muscles. Can have quick myoclonic movements involved. can occur in one part of the body of several. It is usually nonrhythmic.

40
Q

If dystonia occurs in the orofacial muscles it may be called?

A

focal mouth dystonia (essentially the same thing as orofacial dyskinesia)

41
Q

T or F. Writers cramp is a form of dystonia .

A

True

42
Q

what is a spasm?

A

when you have involuntary muscular contractions. can cause both motion and limit motion. Tonic/clonic spasms

43
Q

what is a tonic spasm.?

A

tonic spasms are continuous

44
Q

what is a clonic spasm?

A

‘repetitive and don’t last long

45
Q

what is the etiology of hyperkinetic dys?

A

anything that damages the basal ganglia or cerebellar circuit or indirect activation pathway (extrapyramidal)

46
Q

what are the common disorders we see hyperkinetic dysarthria in?

A 
degenerative dz
toxic-metabolic
vascular disorders
infectious process
neoplasm
tourette's
47
Q

What is Huntington’s chorea?

A

it is a degenerative dz that cause hyperkinetic dys.
it is inherited (genetic)
degenerative CNS disorder
if you have a parent with this dz you have a 50% chance of getting it
distinguished by chorea movements (may also see dementia and personality changes also dysarthria and dysphagia)

48
Q

What is a toxic-metabolic condition that causes hyperkinetic dys?

A

antipsychotic drugs that affect the neurotransmitters (tardive dyskinesia)
often you see this in patients with schizophrenia
if the drugs are withdrawn from early enough the dysarthria will go away (can go away)

49
Q

T or F. You normally don’t see a lot of vascular disorders that cause hyperkinetic dys. Unless there are strokes that affect the basal ganglia or cerebellum.

A

True

50
Q

What is Sydenham’s chorea?

A

it is an infectious process that can cause hyperkinetic dys.

it is seen in young people and can be caused by strep throat normally it is temporary.

51
Q

Where do the tumors have to be to case hyperkinetic dys?

A

basal ganglia and the thalmus

52
Q

Tourettes causes what two type of tics?

A

verbal and motor

53
Q

what do they think that tourettes is caused by?

A

related to problems with dopamine receptor

54
Q

T or F. non-speech complaints are related to the specific disorder the ptnt has that is causing the dysarthria.

A

True

55
Q

Many ptnts with hyperkinetic dysarthria report that?

A

they can’t keep jaw, face, tongue still, report problems of swallowing and chewing.

56
Q

T of F. Some ptnts with hyperkinetic dys may not be aware of their abnormal movements

A

True

57
Q

What are some non-speech and speech signs associated with chorea?

A

non-speech usually normal, size, symmetry, strength of oral facial features
-motor unsteadiness when trying to round or retract lips, protrude tongue or at rest, may see quick, unpatterned movements.

58
Q

how do you want to assess speech in chorea?

A

AMR’s, reading, conversation, vowel prolongation

59
Q

when assessing speech in chorea what do you want to look for?

A

unpredictable movements and breakdown in rate and prosody

  • -phonation: want to look for forced inspiration or expiration, excess loudness variations, strained strangled voice quality, voice stoppages and transient breathiness
  • -resonance: want to look at intermittent hypernasality and weak pressure consonants
  • -Artic: irregular breakdown, distortions, distorted vowels. Slow and irregular AMR’s
  • -Prosody: prolonged intervals and phonemes, inappropriate silences, variable rate, variable stress patterns (PROSODIC COMPONENTS ARE PROMINENT)
60
Q

What are some non-speech signs of dystonia?

A

the movements are slower than chorea normally waxing and waning

  • -oral mech normal
  • -may have problems drooling, swallowing, and facial grimacing
  • -primarily movement problems at rest but sometimes occur in speech
61
Q

What as an example of dystonia?

A

tongue coming out while talking or jaw opening off an on by speaking

62
Q

What can sometimes be used to help with dystonia?

A

botox injected into the tongue

63
Q

what are the speech findings in dystonia?

A

Phonation: voice stoppages, strained-harsh voice, audible inspiration, excess loudness variation, alternating loudness, tremor like voice
Resonance: intermittent hypernasality
Artic: distortion and irregular breakdown, distorted vowels, slow and irregular AMR’s

64
Q

what is spasmodic torticollis?

A

cervical dystonia.
affects the cervical muscles and not muscles innervated by the cranial nerves. Can also have facial spasms.
–speech deviances are related to deviances in neck postures
effects are usuall mild on speech and are primarily at the laryngeal level (pitch variability)
–speech findings:
artic/prosody: may have reduced rate and delayed speech initiation/ slow AMR’s

65
Q

what is palatopharyngeal myoclonus?

A

abrupt movements of the soft palate, pharyngeal walls and laryngeal muscles (effects on speech are not great)

  • -ptnt complains of earclicks (opening and closing of the ET)
  • -can be mild intermittent hypernasality
66
Q

What is action myoclonus?

A

no often seen by SLP’s it is different from other myoclonic disorders bc it is introduced by action and is more rhythmic

67
Q

Tourette’s syndrome is?

A

most are genetically related. typically you see facial grimaces, eye-blinks, twitches of the head.
can also include larger movements (spinning, jumping)
–vocal tics
can include echolalaia, palilalia, coprolalia (swearing compulsively)
most cases are male 4:1
can be accompanied by OCD

68
Q

Are tourettes syndrome more common in males or females?

A

males

69
Q

What is an organic voice tremor?

A

the voice tremor is usually with gradual onset, and worsens with fatigue and stress, may improve with alcohol and is often accompanied by head or jaw or extremity movements

  • -to assess do vowel prolongation
  • -not much affective treatment (botox can help)
70
Q

Spasmodic Dysphonia is caused by?

A

is caused by spasms of the laryngeal adductor or abductor muscles

71
Q

what is spasmodic dysphonia characterized by?

A

strained or breathy voice quality

72
Q

what are the 2 types of spasmodic dysphonia?

A

adductor spasm, abductor

73
Q

adductor spasmodic dysphonia what happens?

A

vocal folds spasm together, increased effort or fatigue (tight strained voice)

74
Q

abductor spasmodic dysphonia?

A

increased effort or fatigue with speaking, may run out of air v.folds spasm open
