motor speech disorders Flashcards
(195 cards)
where is the primary motor cortex found?
frontal lobe
what are the 3 motor processes to produce speech?
planning
programming
execution
what happens in the “planning” process when producing speech?
sequencing of articulatory goals
what happens in the “programming” to produce speech?
preparing the flow of motor info across muscle, control timing, and force of movement.
what happens during the “execution” to produce speech?
activating the relevant muscles.
what are two major speech disorders?
apraxia
dysarthria
do people with apraxia and dysarthria have problems with writing?
no. these are only issues with motor processes.
What is the cause of motor speech disorders?
Neuromuscular and /or motor control system.
Where is the issue for apraxia ?
Planning and sequencing
Where is the issue for dysarthria?
Execution
Where is the disconnect for dysarthria?
Damage is on nervous system pathways. Disconnect between cerebellum and muscles
What can be affected from dysarthria?
Respiration
Phonation
Resonance
Articulation.
What is the cause of motor speech disorders?
Stroke
Head trauma
Progressive diseases
How is the hearing abilities of motor speech disorders?
Fine
Spastic:
Damage where?
Major symptom:
Other signs:
Upper motor neurons
Spasticity
Weakness, increases muscle tone, gagging, drooling, involuntary crying
Ataxic:
Damage where?
Major symptom:
Other signs:
Cerebellum
In coordination
Reduced muscle tone, “intoxicated speech”, wide based gait, tremors
Difficulty with properly planning, programming, and executing motor movements for speech
motor speech disorders.
