Q

Hard Neurological Signs Definition

Study These Flashcards
A

Give clear evidence of neurological dysfunction

23
Q

Soft Neurological Signs

Study These Flashcards
A

Correlated with but do not confirm neurlogic dysfunction
Not unusual for any child under 8y b/c they reflect immature CNS
More often present in children w/ developmental disabilities & those w/ TBI than typically developing children

24
Q

Hard & Soft Neurological Signs

Study These Flashcards
A

Difficult to interpret without additional info from comprehensive eval
Diagnosis shouldn’t be solely based on presence or absence of 1+ neurological signs
Kids must be at least 2 SD below in 1 area or 1.5 SD below in 2 areas: cognition, communication (receptive & expressive), social-emotional, motor skills (fine & gross), self-help/adaptive skills

25
Hard Neurological Signs Include but Aren't Limited to...
Abnormal infantile reflexes in non-infants (Babinski, rooting, etc.) Disrupted motor function in 1+ areas (unilateral paralysis or paresis) Disrupted sensory function in 1+ areas (loss of vision) Dysarthria (slurred speech) not due to medications or physical injury Apraxia of speech or limbs; aphasia
26
Soft Neurological Signs Include but Aren't Limited to...
Hyperkinetic motor overflow (constant extremities movement) Impulsivity (responding prior to thinking or being given all info) Distractability internally (daydreaming) & externally (env'tal sights & sounds) Inattention or difficulty focusing on 1's work Heavy use of concrete thinking based on stimulus thinking (bus is yellow w/ wheels as opposed to vehicle or mode of transport) Slowed processing speed Simultaneous movement of opposite limbs or digits that are unintended based on task Uncoordinated movement; slow motor movement Immature grasp of writing instrument/ difficulty drawing Late milestone development
27
Flow of Assessment
Chart Check First!!! Orientation->automatics->following directions->organization->math->auditory processing->memory->functional problem solving->multifactor problem solving-> deductive/inductive reasoning->divergent thinking/abstract reasoning->convergent thinking/drawing conclusions->reading passages
28
Orientation in Assessment:
name, where they are, season
29
Automatics in Assessment:
Things you automatically know without thinking about; ability to count from 1-20, ABCs, days of week (DOW), months of year (MOY) (Can also check for dysarthria during DOW & MOY) MOY starting at July; count by 2s, 3s, 4s, etc.
30
Following Directions in Assessment:
start simple and move to more complex
31
Organization in Assessment
``` Sequencing Categorization (rapid naming, convergent/ divergent naming, similarities & differences, which 1 doesn't belong & why) ```
32
Math in Assessment
word problems
33
Divergent Thinking/Abstract Reasoning in Assessment
verbal absurdities, humor, etc.
34
Levels of Consciousness
Alert, lethargic, apathetic, aggressive, fluctuating
35
Alert level of consciousness
Fully awake & appropriate responsive to internal/external stimuli; still may have cognitive deficits
36
Lethargic level of consciousness
Not fully awake; may drift in/out of awareness when not being stimulated May appear sleepy or confused with poor arousal or energy
37
Apathetic level of consciousness
Lacks motivation or initiation for goal-directed behaviors or volitional activities; shows diminished concern for things that were previous interests; loss of enthusiasm
38
Aggressive level of consciousness
Irritability & tendency for dis-inhibited verbal/nonverbal impulsivity; often temporary as pt recovers
39
Fluctuating level of consciousness
variations in levels of awareness, energy, behaviors
40
Recovery Issues
Your role will change based on your setting | Will have to adapt evals & tx's to fit the needs of the pts
41
3 Stages of Recovery
Early, middle, late
42
Early Stage of Recovery Goals
Acute stage will require max therapeutic support Determine if pt can... comprehend commands & ?s, make needs known Are cog. skills adequate for communication Is there need for coma management techniques? Presence of dysphagia? Family education needs? Role(s) of family in therapy Staff education re: pt's needs
43
Middle Stage of Recovery Goals
Client may appear more "normal" Is client ready to return to community w/ support or independently? Determine... Type/level of cog-comm breakdown Any compensatory strategies Best methods family can use to help client What about: caring for kids, independent fx'ing, finances management, societal expectations ?s may arise about client's competency Note delayed response times (latency periods), perseveration, failure to note errors, difficulty following instructions
44
Late-Stage of Recovery Goals
Discharge: focus no longer on formal testing but on real-life situations (See chart) Focus more on rehab & home-based situations
45
Pediatric Recovery Issues
Recover from brain injury differently Some may "seem" to recover back to premorbid fx'ing levels but higher cognition must be assessed Difficulties may not be obvious immediately; think about executive fx Ongoing limitations w/ learning/memory can make it difficult to maintain age/grade level progress in school; slowed processing can affect socialization w/ age-matched peers Brain injury recovery takes much longer than other medical conditions; most recovery takes place during 1st 6 mos; fx'al gains can be made after 6 mos, but are much slower Slow/steady becomes normal Recovery due to plasticity
46
Processes of Recovery "Positives" Microscopically
Brain cells may produce new dendrite branches for new connections w/ other cells Previous cell connections may be strengthened or altered to change on how info is processed Axon terminals may change amt of neurotransmitters released, making connections more effective Axons may produce sprouts to re-establish synaptic connections
47
Processes of Recovery "Negatives" Microscopically
Recovery only involves the cells that were undamaged in injury W/ a few exceptions, only cells w/in area of injury can help w/ recovery Cells from undamaged areas of brain generally don't take over functions for other damaged areas Cell growth involving axons & dendrites takes place @ roughly 1/1000 or .001 meters per day; this accts for the slow rate of brain recovery after an injury
48
Predictors of Recovery
In general, 3 main variables: 1. Physical aspects of the injury 2. Premorbid functioning 3. Support network & available resources
49
Physical aspects of injury in predicting recovery
Type of injury, severity of injury, extent of injury (diffuse vs. localized)
50
Premorbid functioning in predicting recovery
people w/ healthy brains & adequate intelligence prior to injury will do better than those w/ developmental disabilities
51
Support network & available resources in predicting recovery
Supportive families & resources that allow for more therapy or education assistance after leaving hospital will generally recover better than those that do not
52
Patterns of Recovery:
Every case will differ, but some patterns are: Kids w/ more severe injuries less likely to improve over 1st 2 yrs following injury than those w/ less severe injury Kids will progress thru stages of recovery similarly but progression may vary & plateau; recovery of skills can take days, wks, mos, & yrs Kids may go thru multiple periods of rapid gain followed by days or wks of little recovery
53
Rates of recovery vary secondary to...
medical complications, fatigue, pain, attention deficits, motor limitations, frontal lobe dysfunction
54
