Neuro: week 11 (perceptual dysfunction)

it is preferable to assess neurobehavioral deficits directly from the ADL evaluation

deficits in visual perception may lead to what?

this test evaluates perceptual and perceptual-motor dysfunction in the context of ADLs and functional mobility tasks

assessment: present client with photograph that has detailed visual array, ask them to describe the scene in detail

seeks to produce some change in CNS function

adaptive approaches and comensatory approaches can be used interchangably

toglia's multicontext treatment approach establishes a criterion for the

toglia's multi-context treatment approach incorporates _____ and practicing in multiple environments

assessment: ask client to name color of various objects in their environment

aims for transfer of learning to occur

mechanism by which the brain interprets sensory info recieved from the environment and is processed

assessment: have client ID names of people in photographs, or have client ID own face in mirror

An individual may chosses to respond to their perception with a ____ or a _____

depth perception

intervention: provide an opportunity to recognize, identify, and name various colors of objects in their environment

repetitive practice will help individual gain independence by using alternative strategies to compensate for impairment

adaptive and remedial approaches can only be used in isolation and never together

inability to recognize specfic colors

understanding of one's body parts and their relative positions in space

what is known as the gateway to cognition?

which of the following are things to consider when assessing perceptual dysfunction

double vision

potential impairments due to visual perception deficits include:

inability to recognize objects via visual input

assess: present client w/ objects of different weights and sizes, ask them to order by size/weight through observation

inability to name color of objects

severe perceptual deficits, combined with cognitive deficit, can impact every area of occupation

intervention: focus on helping client construct meaning of visual array through verbal cues and therapeutic questions

what is the most complex level of perceptual dysfunction recovery, and the last to occur

intervention: remedial approach and/or adaptive approach

perceptual dysfunction rehab/recovery works hierarchially from basic to complex; which functions are the most basic

deficits in perception present significant ____ concerns

visual agnosia is caused by what

simultanagnosia is caused by what

inability to name objects

toglia's multi-context treatment approach involves

inability to recognize and interpret a visual array as a whole

provide training in occupational performance to facilitate the client's adaptation to unique environments

visual distortion of objects (physical propertities of size and weight)

assessment: ask client to ID 5 common objects by sight

the optimal battery of standardized assessment tools require what?

what are the general intervention approaches for perceptual dysfunction

intervention: provide client with opportunities to practice distinguishing objects' size/weight in natural environment

assessment: present client with 2 common objects that are accurately colored and 2 objects that are not

prosopagnosia is caused by what

inability to recognize objects

intervention: adaptive/compensatory methods (reliance on intact sensory systems)

inability to recognize familiar faces
