65
emergence from DOC evidenced by
functional communication as evidenced by verbal or gestural yes/no
OR
functional use of 2 or more objects
66
No Response
no discernable reflexive or volitional response noted to stimuli
67
Generalized Response
Response to stimuli is automatic, reflexive, or non-purposeful, and is non-specific
68
Localized Response
Response to stimuli reflects person's ability to regulate incoming sensory information and voluntarily control the response to the stimulation
-localized responses are NOT reflexes and can occur in relationship to the area stimulated
69
Goals of medical management of DOC
1. Maintain physical stability to allow participation as fully as possible in daily routines and therapy
2. Prevent medical complications
3. Provide opportunities for stimulation to the brain through environmental manipulation and pharmacological intervention
70
Common medical challenges associated with DOC
skin breakdown
respiratory
bowel/bladder dysfunction
autonomic dysfunction syndrome
71
Autonomic dysfunction syndrome (ADS)
a problem with the autonomic nervous system (located in medulla and lower brainstem) that controls processes such as digestion, heart rate, the immune system, respiratory rate, etc
72
Symptoms of Autonomic Dysfunction syndrome (ADS)
- dystonia
- agitation
- tachycardia
- diaphoresis
- hyperthermia
- hypertension
- tachypnea
73
How to treat Autonomic Dysfunction Syndrome (ADS)
- environmental control (determining provoking factors such as bright lights, noise, specific movement patterns) and minimizing or eliminating
- medications- propranolol, gabapentin, clonidine, bromocriptine, dantrolene, morphine
74
Neuralgia
pain caused by damage to a nerve of structural change to a nerve
75
Neuroma
when a nerve becomes entrapped in scar tissue
76
Syndrome of the Trephined
- specific to patients who have had had a craniectomy following TBI
- related to surgical site
- characterized as headache, dizziness, cognitive changes,
- involves shrinking of the skin flap after craniectomy due to positional changes

77
Stability Triangle components (for stability to be established and maintained)
1. medical stability
2. behavior stability
3. stable activity plan
78
medical stability
control of medical complications such as pain, sleep disturbance, incontinence, seizures, etc)
79
behavior stability
requires team to assess problematic behavior such as resistance or refusal, mood instability, threatening or demanding behaviors, verbal and physical aggression, property destruction, elopement, self-harm, and substance abuse or misuse
80
stable activity plan
team must explore individual's abilities, interests, and need for support associated with specific activities and settings, and work to minimize all related risks
81
functionally equivalent alternatives
behavior that serves the same function as the target behavior, but is safer, more appropriate, and thus is more useful for the individual
82
operational definition
outlines what exactly will be counted as an occurrence or episode of the behavior; must be observable or measurable, definition must be specific enough such that multiple observers can agree upon what would count as an occurrence
83
focus of neuropsych evaluation
determines how different areas and systems of the brain are working
84
neuropsych assessment process
record review
clinical interview
standardized testing
report and feedback
85
neuropsych evaluation provides
detailed description of individual's abilities, strengths, adn weaknesses in various areas of functioning
86
neuropsych evaluation achieved through
administration of tests that measure behavioral constructs of specific human abilities such as attention and memory, in a standardized fashion
87
neuropsych findings can be used to
determine nature and extent of cog deficits, presence of a neurologically based disorder, understand how cog deficits may contribute to problems in daily life, determine nature and degree of change in cog performance on re-assessment, assist in treatment planning, determine appropriateness of a surgical intervention, and make recommendations for modifications or accommodations in the community
88
ACRM definition of cognitive rehabilitation
systematic, functionally oriented service of therapeutic cognitive activities, based on an assessment and understanding of the person's brain-behavior deficits. Services are directed to achieve functional changes by:
1. reinforcing, strengthening, or reestablishing previously learned patterns of behavior
2. establishing new patterns of cognitive activity or compensatory mechanisms for impaired neurological systems
89
2 fundamental principles of cognitive rehab
neuroplasticity
| adaptability
90
neuroplasticity
ability of nervous system to regenerate and reorganize its structure, functions, and connections
91
restorative cognitive tx goals
aims to reestablish lost functions or develop new functions
92
restorative treatment consists of
repetitive, targeted, consistently challenging exercise thought to facilitate recovery of impaired neural circuits
93
adaptability
individual's capacity to change behaviors in order to adapt to changes in their natural or external environment
94
compensatory cog tx goal
designed to minimize the effect of deficits and to recover a degree of function
95
compensatory tx consists of
development of internal and external environmental strategies that make use of residual, intact abilities and relative strengths`
96
Factors affecting duration of psychiatric symptoms
unique to the individual
- genetic bias concerning mental illness
- effects on the brain
- stressors related to living with a disability
- individual's psychological resiliency
- quality of the person's support network
