Test 2 Flashcards
Patient and Family Education: Holland and Shigaki (1998)
- 3 phases
- Phase I - focus on providing basic information about what is immediately happening
- Phase II - Larger amount of information provided
- Phase III - additional amounts of information, adjusted to meet specific needs of both individual with TBI and their family
Patient and Family Education: Knowles’s (1948)
- Adults need to be involved in planning and evaluation of their instruction
- Experience (including mistakes) provides the basic for learning activities
- Adults are most interested in learning about subjects that have immediate reliance to their job or personal life
- Adult learning is problem centered rather than content oriented
Preferred Practice Patterns: Cognitive-communication intervention according to the WHO-ICF
- Capitalize on the strengths of the patient to address the weaknesses
- Facilitate individual’s activities and participation level by assisting with acquiring new skills and strategies
- Modify contextual factors that are barriers of and facilitators to successful communication and participation
True or False: Interventions targeted activity and participation level may be warranted even if the prognosis for body structure/function is limited
True
Cognitive Communication Intervention should address what?
- Processing of various types of information under ideal conditions (i.e., capacity) and in various activities and settings
- Executive or self-regulatory control over cognition, language, and social skills functioning
- Modification of cognitive and communication demands to facilitate better performance
- Modification of communication and support competences of relevant people in everyday environment
- Development and use of effective compensatory strategies and techniques
- Development of plans for problems other than cognitive communication that may co-occur with the disorder
Cognitive Rehab Therapy (CRT)
- CRT dates back to World War I with soldiers and civilians being treated for TBI
- CRT became more popular in 1970’s demonstrating higher survival rates for those with severe TBI
- CRT became a part of rehab services in the 1980’s
- Evidence demonstrates positive efficacy for effectiveness of CRT for individuals with TBI
Definition of Cognitive Rehabilitation
”Cognitive rehabilitation is a systematic, functionally orientated service of therapeutic cognitive activities, based on assessment and understanding of the person’s brain behavior deficits. Services are directed to achieve functional changes by (1) reinforcing , strengthening, and reestablishing previously learned patterns or behavior, or (2) establishing new patterns of cognitive activity or compensatory mechanisms for impaired neurological systems.” - Harley et al., 1992, p. 63; Institute of Medicine (IOM), 2011.
Categories of CRT Approaches
Restoration
Compensation
Calibration
Restoration
- Seeks to improve, strengthen, or normalize an impaired cognitive function
- Repetition and drill or exercise-like activities targeting cognitive processes that gradually increase in difficulty and demand
Compensation
- Seeks to provide alternative strategies for completing everyday activities, despite residual cognitive deficits
- External and internal approaches
Calibration
- Seeks to refine awareness and self measurements of cognitive performance and use that information to shape behavior after TBI
- Often used in treatment that focuses on metacognition and executive function.
- Offline awareness (metacognitive awareness) is prior to task completion
- Online awareness is how effective the individual conceptualizes and evaluates the task (anticipatory awareness) and the self monitoring skills of error recognition and adjustment of performance accordingly (self—regulation)
Incidence and Prevalence of TBI
- 27 million new cases worldwide (2016)
- Prevlanece is higher for males
- 15% of full time workers suffering TBI will not return to wrok 4 years later
- 40% have neuropsychological needs 1 year post injury
Risk Factors of TBI
- Males > females (at least 2:1)
- Low SES
- Unemployment
- Participation in certain sports/activity-duty military
- Recurrent TBI
- Those with a TBI are three times more likely to get a second TBI
- Low education level
- History of alcoholism/drug abuse
- Comorbidiy and prescription drug use
- diabetes, cardia arrhythmias
- Ethnicity
- ER visits highest for AA and caucasions
- Age
- Children 0-4
- Adolescent ages 15-25
- Adults over 65
Leading causes of TBI in the US
- Falls: 40.5%
The levels of severity (DOD)
- Mild TBI
- Mild TBI/Concussion
- Moderate TBI
- Severe TBI
Two types of TBI
- Open head injury
- Closed head injury
- more frequent
Neurophysiology and cell death following TBI
Cellular
- Following concussion
- immediately post injury
- Disruption of ions, potassium going out of cell while sodium and calcium flood into the cell (AP)
- Glutamate is released
- Because of the dysfunction in the sodium-potassium pump and a higher level of glutamate results in toxicsynapses and slowed communication between neurons
Neurophysiology and cell death following TBI
Diffuse axonal injury (DAI)
- Gradient from peripheral hemispheres to deeper parts of cerebrum
- corpus callosum and dorsolateral midbrain
Neurophysiology and cell death following TBI
Gliosis
- phagocytes permeate area and are in charge of disposing nonfunctioning tissue
- glial cells then permate the area that was vacated
- provide nutrients for regenerating axons or form scar tissue
Know that neuroplasticity occurs in adult brains
- neuroplasticity is greated during development of immature brain
- overwhelming evidence that neuroplasticity occurs in injured and non injured adult brains
- What helps?
- rehab techniques SLPs can do
- medical interventions
- neuroprotective
- pharmacotherapy
- regeneration
Neurobehavioral concerns
- recovery follows predictable pattern
- Personality changes
- apathy
- 20-72%
- dimished goal-directed behavior
- diminished emotions
- more common in individuals also diagnosed with depression
- 4 subtypes
- cognitive
- motor
- sensory
- affective
- apathy
- Impulsivity
- increased irritability
- verbal and physical aggression
- Loss of temper
- impatience
- poor decision making or judgment abilties
- Neurobehavioral changes after TBI are influenced by..
- nature and location of injury
- social support system
Types of Behaviors…
Transient - temporary
Modifiable - therapy to correct
Chronic - teach compensatory strategies
Psychiatric disorders
- After TBI the rate of developing new psychiatric disorder is 48%
- mood, anxiety disorders and psychotic syndromes
- substance abuse can occur 12-22%, general population is 15%
- Depression
- most diagnosed psychiatric disorder after TBI
- 49% of TBI population
-Post traumatic stress disorder - frequently for military population
