Q

What results in abnormal movements in hyperkinetic dysarthria?

A

Failure to inhibit cortical motor discharges. Also, there may be firing from the thalamus that isn’t inhibited causing these movements.
-There may be an imbalance between the excitatory and inhibitory neurotransmitter.

66
What is a neoplasm disorder that may result in hyperkinetic dysarthria?
tumors of basal ganglia and thalamus
67
What is touette?
It can be part of hyperkinetic dysarthria. Causes both verbal and motor tics. Cause probably related to problems with dopamine receptor.
68
What are some nonspeech complaints by patients?
Nonspeech depends on specific disorder. Many repor can't keep jaw, face, tongue still, report problems with swallowing or chewing. Some may be aware of abnormal movements, whereas others may not. Some have learned sensory tricks to hold back movements.
69
What are specifric diseases with nonspeech and speech signs in hyperkinetic dysarthria?

70
What are non-speech finding in Chorea (hyperkinetic dysarthria)?
Normal size, strength, symmetry of oral facial features. Usually motor unsteadiness, when trying to round or retract lips, protrude tongue, or at rest. may see quick, involuntary, unpatterned movements. Swallowing difficulties are often seen and sometimes drooling. -Look for unpredictable movements and breakdown in rate and prosody.
71
How is speech assessed in Chorea?
vowel prolongation reading conversation AMRs
72
What are some speech signs of Chorea?
- Phonation-respiration: sudden forced inspiration or expiration, excess loudness variations, strained- strangled voice, voice stoppage, transient breathiness. - Resonance: intermittent hypernasality and weak pressure consonants. - Articulation: irregular breakdown, distortions, distorted vowels. slow & irregular AMRs - Prosody: prolonged intervals & phonemes, inappropriate silences, variable rate, variable stress patterns. Prosodic components are prominent.
73
What is action myclonus?
Not often seen for SLPs. It is different from other myoclonic disorders because it is induced by action and is more rhythmic.
74
What is TIcs - Tourette's syndrome?
Most are genetically related. Typically you see facial grimaces, eye-blinks, twitches of head. Can also include larger movements, spinning, jumping, etc. There are also vocal tics- which can include odd noises such as grunting, yelling, whistling, squeaking. Can include echolalaia, palilalia, and coprolalia - swearing compulsively -Most cases are male Can be accompanied by OCD
75
Non-speech findings in dystonia?
Oral mech normal slower than chorea -may have problems with drooling swallowing, may have problems with social grimacing. Primarily are movements problems at rest, but sometimes occur in speech. May be waxing and waning.
76
What is an example of dystonia?
lingual dyskinesia: tongue coming out while talking or jaw opening off and on while speaking - exacerbated by the action of speech. Botox is sometimes used to inject tongue. The speech problem is caused by these involuntary movements.
77
How do some people improve dystonia movements?
With sensory tricks. ex. hold pipe to inhibit dystonia or hold a book to prevent tremors.
78
What are some dystonia speech findings?
- phonation: voice stoppages, strained- harsh voice, audible inspiration, excess loudness variation, alternating loudness, tremor-like voice. - Resonance: intermittent hypernasality - Articulation: distortions & irregular breakdown, distorted vowels, slow & irregular AMRs

neurogenic psychogenic unknown reasons
81
What does Duffy say about spasmodic dysphonia caused by neurogenic vs non-neurogenic?
They should be separated for treatment purposes

Voice in spasmodic dysaphonia is characterized by:
strained or breathy voice quality onset is 45-50 years can be exacerbated by stress and fatigue
83
Adductor spasms (spasmodic dysphonia( complaints are:
increased effort and fatigue, may improve with alcohol, tight strained voice.
84
Abductor complaints of spasmodic dysphonia are:
increased effort and fatigue with speaking, may improve with alcohol if tremor based, runs out of air.
85
What is athetosis?
A type of cerebral palsy-speech characteristics similar to those with dystonia or chorea.
86
What is palatophrayngeal myoclonus (PPLM)?
Abrupt movements of soft palate, pharyngeal walls, and laryngeal muscles.
87
What are the effects of palatophrayngeal myoclonus (PPLM) on speech?
Not great. Can be mild intermittent hypernasality.
88
Patients with palatophrayngeal myoclonus (PPLM) often complain of what?
Earclicks which is the opening and closing of ht Eustachian tube because of pharyngeal contractions.
89
Hyperkinetic dysarthria sounds like what other dysarthria?
spastic
90
What is essential (organic) voice tremor?
The voice tremor is usually with gradual onset, and worsens with fatigue and stress, may improve with alcohol and is often accompanied by hand or jaw tremor.
91
What do you to hear essential (organic) voice tremor?
Do vowel prolongation in speech exam
92
At what age does essential organic voice tremor start?
at any age, but often before 50.
93
what are the treatments available for essential (organic) voice tremor?
Not much effective treatment. Botox helps some. Meds for limb tremor may help but meds don't usually help with voice tremor.
94
What helps distingus hyperkinetic dysarthria from other motor speech disorders?
the variable nature of the speech deviances.
