A Classic Example:
Phineas P. Gage
“NO LONGER GAGE”
Phineas P. Gage
 September 1848: 25-year-old Gage was struck with a
tamping iron


13 pounds, 3 feet 7 inches in length, and 1 ¼ inch in diameter
Passed mostly through the left frontal lobe
 April 1849: Almost complete physical recovery
 However, it seems that Gage’s personality changed
dramatically.
Fitful, irreverent, engages in profanity
 Little respect for others
 Impatient when conflicts with his desires
 Very stubborn
 Abandons plans

Introduction:
‘The walking wounded’
 Traumatic Brain Injury (TBI):
 Insult to the brain caused by external
physical force
 May produce a diminished state of
consciousness
 Usually results in impairment of
cognitive abilities or physical
functioning, as well as:
Mood
 Personality
 Impulsive aggression
 Impaired self-regulatory behavior

 TBIs often considered a risk
factor for psychiatric disorders

Amnesia (PTA)

 High risk groups
 Males 15-24 years old
 Substance abusers
 Infants (64% due to child abuse)
 Elderly
 Individuals who have had a prior brain injury
Prevalence:
Note: All prevalence
rates are
approximations.
 Prevalence rates for TBI are high
 5.3 million Americans disabled
secondary to TBI
 TBIs common cause of childhood
acquired disability


475,000 TBIs occur among children ages
0-14 years (1 year; United States only)
1.4 million people sustain a TBI; about
50,000 die, 235,000 are hospitalized,
and 1.1 million are treated and released
(1 year; United States only)
 Behavioral changes after TBI:
 10-21% (mild); 62-67% (severe)
 Personality changes after TBI:
 Approximately 60-80%

 Facial affect recognition

Especially negative emotions: Anger,
disgust, sadness, and fear

aggressive behavior

 Other neuropsychiatric sequelae
after TBI

Psychosis- 0.7-9.8%
 Psychosocial problems
 Increasing unemployment rates
 Effects on family members
 73% of spouses have at least mild
depression
 42-64% of couples eventually divorce
 Disruptions in family functioning- less
effective coping, problem-solving and
communication
 Judgment of personality change
 Example of disinhibited behavior
and impaired social judgment

Taken from a study by
Max, Robertson, &
Lansing (2001)



12-year-old female (1 year post): “At
least I don’t bite anymore”
7-year-old male (6 months post): “He
is more outspoken and blunt”
7-year-old female (1 year post): “Get
back at other people”
6-year-old male (3 years post): “Boy,
you’re fat”
 Several additional characteristics
that affect personality change
after TBI





Anosognosia
Executive dysfunction
Apathy
Hope
Optimism
 Anosognosia (Awareness/Insight)
 Observed when patient does not report,
denies or minimizes difficulties
 Possibly used as a defense mechanism
against the reality of life post-injury
 Over time, impaired awareness may
lead to increased distress
 Less insight = more behavioral
problems and familial stress
 3 possible types of deficits in awareness
Intellectual awareness of deficits
 Emergent awareness deficits
 Anticipatory awareness

 Executive dysfunction
 Purposeful, goal-directed, problemsolving behaviors
 Sub-components may include
Attentional control
 Strategic planning and problem-solving
 Cognitive flexibility of thought and
action
 Concept formation and abstraction
 Information processing

 Apathy
 Occurs in about 66-71% of TBI
population
 May be treated pharmacologically
 Hope and optimism
 Hope
An inner feeling that a problem will
ultimately be solved
 Negatively related to general
maladjustment and suicidal ideation
 More dominant in predicting depression
severity


Optimism

Future orientation with a general
expectancy that good rather than bad
will happen
