Group 1: (Last names A-M)

History of Present Illness:
A 33 year old male is brought to the psychiatric department by
police after he attacked another man in a bar and threatened to
“rip (your) throat out with (my) bare hands”. The pt.
apparently returned from the restroom in the bar to find the
man putting an arm around his girlfriend. The pt. states that
he immediately became ‘ENRAGED” and began to scream
obscenities. The shouting quickly escalated into a full blown
bar brawl, and the police intervened when the patient wrapped
his hands around the man’s throat and pinned him against the
bar.
The pt. admits to numerous incidents of this nature and has
found himself in fights several times each year since late
adolescence. Two months ago, he was arrested for smashing a
car window with a baseball bat when the man “cut him off” on
the highway. He was also fired from several jobs in his late
20’s due to his “hot temper” with coworkers who were trying
to “slight him”. The pt. believes that his actions are sometimes
unreasonable, but the combination of heightened energy,
racing thoughts, and anger makes his urges nearly impossible
to resist.
The pts. girlfriend states that he is a fun loving and charming
man between episodes but starts arguments with her
approximately twice a week. She claims that during his verbal
attacks he will often make demeaning and devaluing remarks
about her. On several occasions he has broken her personal
belongings during trivial arguments. The pt. acknowledges

that he regrets these episodes, but they usually subside within
a half hour and provide an instant sense of relief.
Past Psychiatric History:
No psychiatric history or past use of psychiatric medications is
reported. The pt. denies symptoms of a mood disorder. He
admits to 1 or 2 alcoholic drinks per week and a history of
marijuana experimentation in his late teens.
Mental Status Exam:
The pt. appears well built and sharply dressed and looks his
stated age. He is awake, alert and oriented in all spheres.
Behavior is appropriate, and eye contact is good. Speech is
clear and coherent with normal rate, rhythm, and volume.
Mood is euthymic, and affect is full. Thought process is logical
and goal directed. Thought content does not include delusions,
ideas of reference, paranoid ideation, suicidal, or homicidal
ideation. Impulse control is poor, as noted by his recent
violent outbursts. Insight is limited because he does not
recognize the maladaptive nature of his behavior. Judgment is
impaired, as evidenced by his inability to behave in asocially
accepted ways. Reliability is fair.
Labs:
Na = 141, K=4.2, Chloride=106, carbon dioxide =23, blood urea
nitrogen=9, creatinine=0.6, glucose=91.
Blood alcohol level and urine tox are negative.
Diagnostic Testing:
CT of the head shows no sign of mass, lesion or bleeding.
Electroencephalogram is unremarkable without signs of
slowing or seizure foci.

Physical Exam:
The man appears healthy, and the exam is within normal limits without remarkable
findings.

ANSWER

Differential Diagnoses

Intermittent Explosive Disorder (IED): The patient’s history of recurrent and uncontrolled episodes of explosive rage, impulsivity, and violent outbursts supports the consideration of IED. These outbursts seem to be out of proportion to the triggering events, and the patient admits difficulty resisting the urges to act on his anger.

Conduct Disorder: The patient’s history of aggression, verbal and physical violence, destruction of property, and disregard for social norms and rules are consistent with Conduct Disorder. The onset of these behaviors in adolescence and the persistent pattern of aggressive conduct raise suspicion for this diagnosis.

Substance-Induced Psychosis or Intoxication: While the patient denies current substance use, it is essential to consider the possibility of substance-induced psychosis or intoxication, as drugs and alcohol can sometimes trigger aggressive behaviors and impair judgment.

Diagnosis and Reasoning

Based on the patient’s history of recurrent violent outbursts, verbal attacks, and impulsivity, the most likely diagnosis is Intermittent Explosive Disorder (IED). The patient’s inability to control his anger, coupled with the immediate sense of relief after outbursts, further supports this diagnosis. Additionally, the absence of significant mood disturbances and the lack of any delusional or paranoid thinking rule out other mood or psychotic disorders.

Time Consideration for Differentiating Adjustment Disorders from PTSD

In this case, there is no indication of a traumatic event or significant stressor that would suggest PTSD. The patient’s history of aggressive behaviors since late adolescence, coupled with recurrent episodes of explosive rage, indicates a chronic pattern of behavior consistent with IED. While PTSD is usually triggered by a specific traumatic event and has a delayed onset of symptoms, IED is characterized by recurrent, sudden, and disproportionate outbursts of aggression.

Difference between Oppositional Defiant Disorder (ODD) and Conduct Disorder (CD)

Oppositional Defiant Disorder (ODD) and Conduct Disorder (CD) are both disruptive behavior disorders diagnosed in children and adolescents. The key difference lies in the severity and patterns of behavior:

Oppositional Defiant Disorder (ODD): ODD is characterized by a pattern of defiance, disobedience, and argumentativeness toward authority figures, such as parents, teachers, or other adults. Children with ODD often display negative, resentful, and hostile behavior but do not engage in physical aggression or violate the rights of others.

Conduct Disorder (CD): CD is more severe than ODD and involves a persistent pattern of violating the rights of others and societal norms. Children and adolescents with CD display aggressive behavior, such as physical fights, cruelty to animals, property destruction, and theft. They may also engage in lying, truancy, and other delinquent behaviors.

Additional Questions for Obtaining More Information

Inquire about the frequency, intensity, and triggers of the patient’s violent outbursts and verbal attacks.
Ask about the patient’s childhood behavior and whether he displayed aggression or conduct issues during adolescence.
Explore any history of traumatic events, abuse, or neglect that may have contributed to the development of his aggressive behaviors.
Obtain information about the patient’s social and family environment to identify potential stressors or conflicts.

Medication Recommendations and Rationale

Selective Serotonin Reuptake Inhibitors (SSRIs): SSRIs may be considered to manage impulsive aggression and temper outbursts. They can help regulate mood and reduce aggressive tendencies in patients with IED.

Antipsychotic Medications: Atypical antipsychotics may be prescribed for their mood-stabilizing effects and potential to reduce aggressive behavior.

Mood Stabilizers: Medications such as lithium or anticonvulsants may be considered for their mood-stabilizing properties, especially if the patient exhibits mood fluctuations.

Side Effects vs. Benefits vs. Risks of Medications

While medications can be beneficial in managing symptoms, it is essential to consider the potential side effects and risks associated with each medication. SSRIs may cause nausea, sexual dysfunction, or mood changes. Antipsychotics and mood stabilizers may lead to weight gain, sedation, and metabolic disturbances. A careful risk-benefit analysis should be conducted, weighing the potential benefits of symptom reduction against the possible side effects and risks.

Labs and Why They May Be Indicated

Given the patient’s history of aggressive behaviors and impulsivity, lab tests may be necessary to rule out any organic causes of aggression. Potential labs may include:

Complete Blood Count (CBC): To rule out anemia or other blood abnormalities that may contribute to irritability and mood changes.

Thyroid Function Tests: Thyroid dysfunction can cause mood disturbances and behavioral changes.

Toxicology Screen: To rule out any underlying substance use that may be contributing to the patient’s symptoms.

Screener Scales or Diagnostic Tools

Disruptive Behavior Disorders Rating Scale (DBDRS): This tool can assess disruptive behaviors and aggression in children and adolescents, aiding in the diagnosis of ODD and CD.

Aggression Questionnaire (AQ): The AQ can evaluate aggressive behaviors and hostility levels in individuals.

Additional Resources

Therapy Modalities: Cognitive-behavioral therapy (CBT) can be beneficial in teaching coping strategies, anger management, and emotional regulation skills.

Support Groups: Connecting the patient with support groups for individuals with anger management issues can provide a sense of understanding and camaraderie.

Activities: Encouraging the patient to engage in stress-reducing activities, such as physical exercise or mindfulness practices, may help channel aggression positively.
