Exam 1 Part 14 Flashcards
Impairment in motor programming for speech but not for non-speech acts.
Apraxia
What are the 2 etiologies of apraxia?
Acquired (adult), developmental (child)
True or false: Verbal apraxia can occur with or without oral or buccofacial apraxia (non-speech)
True
What are the muscles like in apraxia?
Muscles are okay in relation to tone, strength, range, can do normal function for non-speech acts
Apraxia is frequently a secondary diagnosis for what 2 conditions?
Dysarthria, aphasia
Where is the location of damage for apraxia?
Cortex and subcortical structures (supplementary motor area/ premotor area)
Area of the brain that receives input from Broca’s area, sends to motor strip
Premotor area
Area of the brain that control & intitiation of volitional speech
Supplementary motor area
What is the primary etiology of apraxia in adults?
CVA
The lesion for apraxia is more common in the _____ hemisphere
Dominant
Area of the brain in charge of facial reaction, motor refinement of speaking/writing;
Insula
Area of the brain associated with the Broca’s and Wernicke’s area in apraxia of speech; helps us to sound out words
Supramarginal gyrus
What are some sites of lesions for apraxia?
Premotor area, supplementary motor, supramarginal gyrus, primary sensory strip, insula
What is the most common etiology of apraxia (site of lesion)?
Supplementary motor
What type of aphasia can co-occur with apraxia?
Non-fluent (Broca’s)
