Pt can be aroused only briefly with vigorous, repeatedly sensory stimulation
38
Describe the characteristic of pt that is obtunded
* Pt sleeps often | * when aroused, shows decreased alertness & interest in the environment

46
Enumerate or write the grading for severity of TBI
47
Enumerate or write the table of responses in Glasgow Coma Scale
48
Enumerate or write the Glasgow Outcome Scale Extended
49
- pt appears to be in deep sleep | unresponsive to any stimuli
RLA | I. No respone
50
- Responses may be physiological changes or in nature - Gross body movement and/or vocalizations - Responses are not related to the type of stimulus presented
RLA | II. Generalized Response
51
- Pt is in heightened state of activity - Behavior is bizarre and non-purposeful - Pt. lacks short and long-term recall
IV. Confused Agitated
52
- - Responses are directly related to the type of stimulus presented - May follow simple commans in an inconsistent and delayed manner
RLA | III. Localized Response
53
- Pt. is able to respond to simple command fairly consistently - Memory is severely impaired - Unable to learn new Info
RLA | V. Confused Inappropriate
54
- Pt. shows goal directed behavior - May follow simple directions - There is a carry over re-learned tasks such as self-care activities
RLA | VI. Confused Appropriate
55
- Learning at a decreased rateJudgement remains impaired - Robot-like behavior - - May initiate social/recreational activities
RLA | VII.Automatic Appropriate
56
- There is environmental awareness | - (+) learning without supervision
RLA | VIII> Purposeful Appropriate
57
the center of the team
Patient et Family
58
overseeing the care of the patient with a brain injury
Physician
59
- Examines, evaluates, and treats communication, swallowing and cognitive impairments - With their guidance, the team will be able to devise the most effective and consistent way to communicate with the patient - will also be able to instruct the team in how the patient's cognitive impairments may impede new learning
Speech-Language Therapist
60
Examines, evaluates, and treats the patient's diminished ability to perform ADL
Occupational Therapist
61
Responsible for dispensing medications and closely monitoring their effects will initiate a bowel and bladder retraining program to assist the patient in learning to become continent again
Rehab Nursing
62
- Often a nurse, social worker, or other health professional | - Will direct team meetings, schedule family conferences, and act as a liaison with third-party payers
Case Manager/ Team Coordinator
63
Provides much needed support to both the patient and family
Social Worker
64
- Will often perform neuropsychological testing when appropriate to determine the patient's base-line cognitive functioning - will also assist the team in developing a behavioral management program
Neuropsychiatrist
65
Failure to drive specific brain function can lead to functional degradation
Use it or lose it
66
Training that drives a specific brain function can lead to an enhancement of that functions
Use it to Improve it
67
the nature of the training experience dictates the nature of the plasticity
Specificity
68
Induction of plasticity requires sufficient repetition
Repetition Matters
69
Induction of plasticity requires sufficient training intensity - increase difficulty
Intensity Matters
70
Different form of plasticity occur at different times during training
Time Matters
71
The training experience must be sufficiently salient to induce plasticity - the training should be meaningful to the patient's condition
Salience Matters
72
Training-induced plasticity occurs more readily in younger brains
Age Matters
73
Plasticity in response to one training experience can enhance the acquisition of similar behaviors - one training can enhance the other
Transference
74
Plasticity in response to one experience can interfere with the acquisition of other behaviors
Interference
