Flashcards in Heminneglect and apraxia Deck (16):
1

Define abulia

lack of motivation

2

Define agnosias

Absence of knowledge and insight

3

Define alexia

Inability to read

4

Define apraxia

inability to performed learned tasks AFTER COMMAND, and have to break down to parts and perform them each part at a time.

ex. seatbelt

5

What is gerstman's syndrome? What lesion causes it

Left parietal lesion
Acalculia
Agraphia without alexia
finger agnosia
impaired left right discrimination

6

If no right parietal lesion, what else could cause hemineglect?

Cingulate (motivator area)
Right prefrontal area
R striatum, posterior internal capsule, and thalamus

7

define anosagnosia

Ioss of self awareness. " i know im in the hospital but i dont know why"

8

Other than the frontal lobe, what is responsible for attention (monitoring/selecting)?

Brain stem, cerebellum, thalamic arousal system

9

What are the different kinds of apraxia?

Limb
ideomotor
Ideational
Apraxia of speech
Gait apraxia

10

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

11

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

12

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

13

What is ideational apraxia?

Sequencing problem
however, one step action is preserved

14

How do you lose praxis?

Disconnection or destruction of DOMINANT hemisphere association areas (supplementary motor area)
Not hemiperesis

15

What are the most common causes of apraxia?

corticobasal syndrome
Alzheimer's
Progrssive spranuclear palsy
stroke
parkinson's

16

Is apraxia pathognomonic for a specific dementia?

no. it comes and goes, and can occur with any dementia
