Traumatic Brain Injury (TBI)
TBI results from: Penetrating Closed head injury
Prevalence cases of TBI/year in U.S. of these: die individuals have significant, long- term impairments every 15 seconds a person sustains a TBI
Causes of all TBIs are caused by motor vehicle accidents (MVA) Other causes Affect more males than females (2:1) highest frequency
Neurology Unlike stroke, TBI is brain damage is usually Damage can be to:
Damage is due to the injury due to impact (in that area) injury on the side opposite to the impact damage due to angular acceleration of the brain
Secondary effects Cerebral Hemorrhage --> hematoma: cerebral edema: increased
Coma Not all TBIs result in coma, but many do There are different levels of coma, measured on a Glasgow coma scale Rancho Los Amigos scale
Rancho Los Amigos Scale of Cognitive Levels inconsistent responses to intense stimuli (e.g., pain) blinks to strong light, turns toward sound, inconsistent response to commands
alert, active with aggressive behavior. Behavior is not purposeful, patient is disoriented gross attention to environment, highly distractible, responds to simple commands
inconsistent orientation to time and place, recent memory impaired performs daily routine in familiar environment, poor insight, judgment, and problem-solving responds appropriately in most situations
Impairments resulting from TBI Cognitive Physical Speech and Language Behavioral and Emotional
Potential Cognitive Problems Orientation Slowness of thinking Difficulty maintaining attention and concentration Reasoning and problem solving
Physical problems can include Potential Physical Problems Vision problems Lack of coordination Weakness or paralysis of muscles Problems sleeping
Potential Speech & Language Problems Speech ( ) Language impairment ( ) Commonly: anomia & impaired comprehension Problems with Voice & Swallowing Reading/writing
Potential Behavioral and Emotional Problems Lack of motivation Inability to self-monitor (denial) Difficulty with emotional control and anger management
Intervention - Role of SLP May address many areas depending upon client’s needs Orientation Memory Listening comprehension Speech intelligibility Pragmatics Reasoning and problem solving
Recovery is in a step-wise plateau. Cognitive Rehabilitation Treatment regimen designed increase functional abilities for everyday life by improving the capacity to process incoming information Repetitive activities to rebuild neural circuitry Attempted first e.g., classification tasks, word associations, rehearsal, memory aids
Develop alternatives, since some functional will not be recovered. When restorative approaches won’t work E.g., focused attending, rehearsal of new information
Stages of Recovery/Intervention Early Stage Beginning responses to environment in hospital – stabilization Intervention focus: Evidence to suggest that intervention can result in shorter rehabilitation & higher levels of cognitive functioning
Middle Stage Goal: Intervention focus: Orientation to everyday routine Routines, consistency Conversational speech Listening/comprehension Following directions Description, classification
Late Stage Goal: Intervention focus: Comprehension of complex information, directions Conversational/social skills (including problem solving) Compensatory strategies Self-inhibition Self-monitoring skills
