|
impairment in ability to carry out purposeful, skilled movement despite normal primary motor skills and normal comprehension of act not explained by weakness, incoordination, sensory loss, concentration, inattention, or Intellectual impairment |
apraxia |
|
Common etiology of apraxia |
focal lesions, progressive dementia, stroke |
|
Apraxia is frequently associated with what other disorders that make differential diagnosis more confusing |
aphasia and anosognosia or right hemiparesis |
|
Examination for apraxia should include: |
pantomime; evaluation of transitive movements; intransitive movements; and ability to carry out serial acts |
|
impairment in planning the movements necessary for speech production manifested in inconsistent articulation errors and difficulty with correct articulatory placement |
apraxia of speech |
|
disorder of motor coordination |
dysarthria |
|
difficulty performing voluntary skilled motor movements of face, tongue, lips, and cheeks on command |
buccofacial apraxia |
|
How to assess intransitive buccofacial gestures |
puff out cheeks, stick out tongue |
|
How to assess transitive buccofacial gestures |
pretend to suck on straw or sniff a flower |
|
loss of normal capacity to use legs appropriately for act of walking even though can demonstrate when laying down |
gait apraxia |
|
localization of speech apraxia |
uncertain |
|
locations of ideational apraxia |
bilateral nonfocal lesions and with left hemi lesions esp posterior temporal-parietal junction |
|
localization of ideomotor apraxia |
lesions in left inferior parietal lobe or supplementary motor area or lesion in corpus callosum |
|
localization of limb-kinetic apraxia |
pyramidal motor system |
|
loss of ability to plan and execute complex gestures as if lost idea behind it or use tool despite knowledge of it resulting in difficulty motor planning adn errors in sequencing actions to complete task |
ideational apraxia |
|
how to assess for ideational apraxia |
request completion of serial acts |
|
loss of ability to perform or pantomime transitive or intransitive gestures on command and to imitate, although spontaneous production of the gesture may remain intact resulting in using body part as if it were an object |
ideomotor apraxia |
|
how to assess intransitive ideomotor apraxia |
ask to wave or salute |
|
how to assess transitive limb gestures |
ask to pretend to use comb or scissors |
|
inability to precisely move hands or legs not related to skilled movement present with pantomime, imitation, and use of objects affecting goal directed transitive movement more than simple intransitive movement, is more often asymmetric, and affects distal more than proximal movement |
limb-kinetic apraxia |
|
language disorder associated with aphasia and alexia or to primarily motoric and spatial deficits |
agraphia |
|
Part of brain often implicated in emotional regulation |
frontal lobe particularly orbitofrontal and left frontal, right hemi and limbic areas such as amygdala and septum |
|
Disoreder where patients are aware they have impairments but have no emotional distress or concern often presenting with neglect |
anosodiaphoria |
|
localization of anosdiaphoria |
