Flashcards in Heminneglect and apraxia Deck (16):
lack of motivation
Absence of knowledge and insight
Inability to read
inability to performed learned tasks AFTER COMMAND, and have to break down to parts and perform them each part at a time.
What is gerstman's syndrome? What lesion causes it
Left parietal lesion
Agraphia without alexia
impaired left right discrimination
If no right parietal lesion, what else could cause hemineglect?
Cingulate (motivator area)
Right prefrontal area
R striatum, posterior internal capsule, and thalamus
Ioss of self awareness. " i know im in the hospital but i dont know why"
Other than the frontal lobe, what is responsible for attention (monitoring/selecting)?
Brain stem, cerebellum, thalamic arousal system
What are the different kinds of apraxia?
Apraxia of speech
How do you test for ideomotor apraxia?
Ask the patient to show how to do something: wave goodbye, flip a coin
Use a pair of scissors
If unable to do any of that, demonstrate and ask to immitate
What is the difference between limb and ideomotor apraxia?
Clumsiness of movement
Unable due to kinetic function
In ideomotor, they're unable to figure out what to do in first place
someone could start with limb kinetic apraxia, and develop ideomotor later
what are things to watch for during assessment of apraxia?
location of body parts in relation to each other
posture while performing action
action: being able to perform something (make a fist, missing)
plane of action
Orientation of business end to tool
What is ideational apraxia?
however, one step action is preserved
How do you lose praxis?
Disconnection or destruction of DOMINANT hemisphere association areas (supplementary motor area)
What are the most common causes of apraxia?
Progrssive spranuclear palsy
