ANSWERS


Question 1:

From day #100


Answer: b

The diagnostic timeline presented for acute stress disorder is correct.


Explanation: 1


Correct timelines:

  • Adjustment disorder: Symptoms develop within 3 months of the stressor and resolve < 6 months after the stressor has terminated.

  • Acute stress disorder: Symptoms develop within 1 month of the trauma and resolve < 1 month after the traumatic event.

  • Post-traumatic stress disorder: Symptoms develop any time after trauma and symptoms must last > 1 month.

  • Persistent complex bereavement disorder: Symptoms occur more days than not for >12 months.



Question 2:

From day #101


Answer: d

Adjustment disorder


Explanation: 2, 3, 4


  • Prevalence of adjustment disorders vary depending on the setting. Estimates of 2% in the general population; 1-18% in primary care settings; 5-20% in outpatient mental health clinics; 15-20% in psychiatric ED; and ~10% in inpatient psychiatry.

  • It is the most common diagnosis in inpatient psychiatric consultation settings (frequently reaching 50% of consults) and is 3x as common as MDD in medically ill inpatients (~14% vs 5%). Two studies showed a prevalence between 12% and 35% of adjustment disorder in patients with head/neck cancer and breast cancer respectively.



Question 3:

From day #103


Answer: e

Dissociative symptoms is not one of the major criterion for PTSD although it can be seen and is a "specifier" of PTSD.


Explanation:


Diagnostic Criteria for PTSD (adults and children > 6 years old)

  • Exposure to actual or threatened death, serious injury, or sexual violence. Exposure may occur through direct experience or witnessing the trauma (see "what is trauma" above for details).

  • Timing: Trauma occurred at any time in the past. Symptoms last > 1 month. Contrast this with acute stress disorder (trauma occurs < 1 month ago and symptoms last > 3 days and < 1 month).

  • Intrusive symptoms (≥1): recurrent and intrusive re-experiencing of the event. Can occur via memories, nightmares, or "flashbacks" (dissociative reactions). May include intense psychological distress or physiological reactions to cues relating to the trauma.

  • Avoidance behaviors (≥1): active and persistent avoidance of reminders of the trauma which can include internal (memories/thoughts/feelings) and external (people/places/conversations/activities/situations) reminders.

  • Mood/Cognitive alterations (≥2): negative alterations of mood or cognitions can include amnesia, negative beliefs about self/others/world, distorted sense of self-blame, persistent negative emotions (guilt, fear, anger, etc.), anhedonia, feelings of detachment or isolation, and inability to experience positive emotions.

  • Arousal/Reactivity alterations (≥2): increased arousal/reactivity manifested in a number of possible ways such as irritability/anger, reckless behavior, hypervigilance, exaggerated startle response, difficulty concentrating, or insomnia.

  • Specifiers

  • With dissociative symptoms. Depersonalization = feeling of being detached from your mental process or body. Derealization = feeling of unreality of surroundings. Make sure this is not due to substance use or another medical condition.

  • With delayed expression. If the full diagnostic criteria are not met until >6 months after the event.


Helpful MNEMONIC = TRAUMA

  • Traumatic event

  • Re-experience

  • Avoidance

  • Unable to function

  • Month or more of symptoms

  • Arousal increased
