Diffuse axonal injury
Severe brain injury caused by extreme shearing forces
Persistent post concussive symptoms
A complex disorder following a concussion, lasting for weeks or months, consisting of
symptoms such as headaches or dizziness, Nausea, post Trumatic amnesia and GCS of
13/14
Must be diagnosed by neuropsychologist
Somatization
The expression of psychological distress through physical symptoms
Chronic traumatic encephalopathy - CTE
Rare, progressive, degenerative condition of central nervous system that is seen and
repetitive brain trauma
Dementia, memory loss, aggression, confusion, depression
,Hebbian Learning
Neurons that fire together, wire together
Experience independent learning
" use it or lose it"
Synaptogenesis
The process by which neurons form new connections
Disorders of consciousness
Coma, Vegetative State, minimally conscious state
Coma
* no evidence of arousal
* no response to internal or extrnal stimuli
* May have reflexive response
* resolves in 2 to 4 weeks
,Vegetative state
Transition of severely brain damaged patients from a coma to wakefulness without
awareness
Can be months to years in this state
Minimally conscious state
condition in which someone has brief periods of purposeful actions and speech
comprehension
Emergence from DOC
Requires at least one criteria:
* functional communication by verbal or gestural Y/N response
* functional use of 2 or more objects
Automatic dysfunction syndrome
Episodes of: dystonia (abnormal muscle tone), tachycardia, diaphoresis (sweating),
hyperthermia, hypertension, tachypnea (rapid breathing)
*occurs in 15%-33% of severe TBI
Sleep Complications
, Hypogenic hallucinations - vivid dream like auditory, visual, or tactile sensations on
experiences between sleep and wake
Cataplexy - feature of narcolepsy. Sudden loss of muscle tone. Consciousness
remains clear, memory not impaired and respirations intact
Children & TBI
* non-accidental trauma cause of 80% of deaths in children under 2yo
* 2/3 of children under 3yo that are abused have TBIs
*falls cause 1/2 of TBI in 0-14yo
domestic violence
67% of women in domestic violence had TBI symptoms
Mild TBI
*concussion
*LOC > 30 min
*loss of memory >24hrs
*CGS 13-15
*normal CT or MRI
*any AMS at time of incident
