Hyperkinetic Dysarthria Flashcards
Due to lesions in the basal ganglia circuit it;s _______.
extrapyramidal
What does extrapyramidal mean?
It refers to those motor pathways that do not pass through the pyramids at the medullary-spinal level.
________ refers to those motor pathways that do not pass through the pyramids at the medullary-spinal level.
Extrapyramidal
What systems does hyperkinetic dysarthria affect?
All sub-systems, but it mainly affects prosody and rate of speech.
Some of the ______ dysarthrias reflect problems with sensorimotor integration for speech motor control.
hyperkinetic
Some of the hyperkinetic dysarthrias reflect problems with ______ ________ for speech motor control,
sensorimotor integration
Lesions resulting in ________ dysarthria cause speech characteristics related to abnormal rhythmic or irregular (so may be regular or irregular) and unpredictable, rapid or slow involuntary movements.
hyperkinetic
Lesions that result in hyperkinetic dysarthria cause what kind of speech characteristics related to movement?
abnormal, rhythmic or irregular may be regular or irregular and unpredictable, rapid or slow involuntary movements.
What do you need to keep in mind for hyperkinetic dysarthria in terms of movement?
That they are involuntary movements
In hyperkinetic dysarthria it looks in many cases that the person is producing _____ speech and then these _____ movements ______ the speech.
normal
involuntary
distort
Abnormal movements in hyperkinetic dysarthria may only be present during ______.
speech
What results in abnormal movements in hyperkinetic dysarthria?
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.
Abnormal movements in ________ dysarthria may be the result of a Failure to inhibit cortical motor discharges. Also, there may be firing from the thalamus that isn’t inhibited causing these movements.
hyperkinetic dysarthria
ACH is excitatory or inhibitory?
Excitatory
Dopamine is excitatory or inhibitory?
Inhibitory
What does the term hyper in hyperkinetic mean?
means movements that don’t belong, extra movement. The voluntary movements of these patients may be slow.
Why do we subdivide categories of movement disorders in hyperkinetic dysarthria?
Even though involuntary movements are the theme that tie these together as hyperkinetic dysarthria, there is considerable variability in each of them, in their character and underlying pathology.
What are the etiologies for hyperkinetic dysarthria?
Multiple, but mainly toxic-metabolic and idiopathic causes are the most frequent. Most are unknown etiologies.
How can hyperkinetic dysarthrias be distinguishable from other dysarthrias?
Just by visual observing - because of the strange movements.
Some of the bizarreness of the movements in hyperkinetic dysarthria may cause the person to be incorrectly diagnosed as having ________ problems.
psychogenic
What are the 9 categories of hyperkinetic dysarthria?
- dyskinesia
- myoclonus
- tics
- chorea
- ballism
- athetosis
- dystonia
- spasm
- tremor
What is dyskinesia?
Diskinesia occurs in hyperkinetic dysarthria and it refer to abnormal hyperkinetic, involuntary movement. It can occur in various part of the body.
What are abnormal, hyperkinetic, involuntary movements of the mouth, tongue and jaw called?
orofacial dyskenisias
What are orofacial dyskinesias?
abnormal hyperkinetic, involuntary movements in the mouth, tongue, and jaw. Don’t have to have any other parts of body involved.
What do orfacial dyskinesia usually result from?
prolonged use of anti-psychotic drugs
oral facial diskinesia that result from prolonged use of anti-psychotic drugs is also referred to as _______ ______.
tardive dykinesia
What are manifestation examples of tardive dyskinesia/oral facial dyskinesia?
lip smacking
pursuing and retraction of lips
tongue protrusion
opening or closing of jaw
______ is a diskinesia where you have motor restlessness demonstrated by pacing, moving around a lot, rubbing head. it is due to damage to basal ganglia circuit.
Akathisia
What is akathisia?
A type of dyskinesia (hyperkinetic dysarthria) where you have motor restlessness demonstrated by pacing, moving around a lot, rubbing head, etc. Due to damage in basal ganglia circuit.
What is myoclonus?
Single, involuntary, brief movements of 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 movement itself. may occur in epilepsy.
________ is a Single, involuntary, brief movements of 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 movement itself. may occur in epilepsy.
Myoclonus
Why does myoclonus occur?
Lesions from the cortex to the spinal cord.
What is a type of myoclonus?
Hiccups
______ are a type of myoclonus-spasms of the diaphragm and adduction of vocal cords.
Hiccups
Hiccuping can be a sign of involvement with the _____.
medulla
What are tics?
They are typically seen in tourette’s syndrome. They are rapid, patterned movement under partial voluntary control. The person may have some voluntary control over them.
Simple tics may look like _____ or ______, but complx tics don’t.
dystonia
myoclonus
What is chorea?
A hyperkinetic disorder of rapid involuntary, random purposeless movements of a part of body. It is nonrhythmic and random. can be present at rest and in voluntary movement. Can be subtle or severe.
