Exam prep questions Flashcards
What are the mood disorders according the DSM-5 discussed in lecture 4?
Major Depressive Disorder.
Persistent Depressive Disorder.
Pre-menstrual Dysphoric Disorder.
Bipolar I and Bipolar II disorder.
What is one of the disorders included in the ICD that is not included in the DSM-5 that we discussed at length in lecture 7?
cPTSD.
Are women or men more likely to develop PTSD?
Women.
What is the difference between delusions and hallucinations?
Delusions are fixed beliefs that do not shift with conflicting evidence.
Hallucinations are sensory or auditory experiences that are illicited without an external stimulus.
What are negative psychotic symptoms according to the DSM-5?
- Diminished emotional expression.
- Avolition - inability to engage in or initiate goal-oriented behaviours.
3.Alogia - diminished speech output. - Anhedonia.
- Asociality.
According to DSM-5, what is a brief psychotic disorder?
Psychotic symptoms last less than one month and more than one day.
What are the five psychotic disorders from DSM-5 we discussed in lecture 5?
- Brief Psychotic Disorder.
- Delusional Disorder.
- Schizophreniform disorder.
- Schizophrenia.
- Shizoaffective Disorder.
How is Delusional Disorder defined in DSM-5?
Delusional disorder is characterized by at least one month of delusions, but no other psychotic symptoms.
What is the difference between Schizofreniform disorder and Schizophrenia?
Schizophreniform disorder meets all the requirements for schizophrenia, except that the symptoms have been present for less than 6 months and more than 1 month and there is no requirement for a decline in functioning.
Do men tend to develop psychosis earlier than women?
Yes.
What is one of the genes that has been indicated in Schizophrenia that we discussed in lecture 5?
COMT gene. The COMT gene is involved in maintaining functional levels of dopamine. It’s role in Schizophrenia development and progression is not yet fully understood.
What is the dopamine hypothesis for schizophrenia development and progression?
That excessive dopamine activity leads to the experience of psychotic symptoms.
What is the SOCIAL DEFEAT HYPOTHESIS of Schizophrenia?
The social defeat hypothesis states that experiencing social exclusion and negative social experiences sensitises the mesolimbic dopamine system, thereby increasing risk of experience psychotic symptoms.
This may explain why people that are part of oppressed groups or minority groups experience heightened risk of experiencing psychotic symptoms.
How does the DSM-5 define obsessions?
How does the DSM-5 define compulsions?
Obsessions:
1. Recurrent and persistent thoughts, urges, or images that are experienced, at some time during the disturbance, as intrusive and unwanted, and that in most individuals cause marked anxiety or distress.
AND
2. The individual attempts to ignore or suppress such thoughts, urges, or images, or to neutralize them with some other thought or action (i.e., by performing a compulsion).
Compulsions:
1.Repetitive behaviors (e.g., hand washing, ordering, checking) or mental acts (e.g., praying, counting, repeating words silently) that the individual feels driven to perform in response to an obsession or according to rules that must be applied rigidly.
AND
2. The behaviors or mental acts are aimed at preventing or reducing anxiety or distress, or preventing some dreaded event or situation; however, these behaviors or mental acts are not connected in a realistic way with what they are designed to neutralize or prevent, or are clearly excessive.
What is one of the main obsessions and compulsions individuals with OCD experience?
Fear of harming others manifesting as a checking compulsion.
Is there a gender difference in prevalence of OCD in adults?
No.
More men develop OCD as children. Women tend to develop it in adulthood.
Mean age of onset is 19 years.
What is one of the genes that has been linked to OCD that we discussed in lecture 6?
hSERT gene.
Mutations in this gene that increase the efficacy of this gene have been implicated in OCD. The gene reuptakes serotonin from the synapses, therefore a too-efficient hSERT gene decreases “normal” levels of serotonin in the synapse.
Is there a disparity in prevalence of BDD between men and women?
No.
Shocked me.
What are the disorders discussed in lecture 6 ‘OC and related disorders’?
- OCD.
- BDD.
- Hoarding Disorder.
- Trichotillomania Disorder.
- Excoriation Disorder.
What are the specifiers for Adjustment Disorder in the DSM-5?
- With depressed mood.
- With anxiety.
- With mixed anxiety and depressed mood.
- With disturbance of conduct.
- Unspecified - for maladaptive reactions that do not meet the specifiers mentioned above.
When is an adjustment disorder likely to be diagnosed?
When an individual meets criteria for PTSD but criterion A. Or when individual meets criterion A and some other, but not all of the other criteria for PTSD.
What is the difference between Acute Stress Disorder and PTSD?
Acute Stress Disorder describes distress and reactions to a traumatic event that develop 3 days after and before 1 month of the traumatic event.
PTSD on the otherhand tends to last for months to years.
It should be noted that disturbance often develops immediately after the traumatic event, but to meet criteria for Acute Stress Disorder, the disturbance needs to be present for at least 3 days.
What are the trauma- and stressor-related disorders discussed in lecture 7?
- PTSD.
- Acute Stress Disorder.
- Adjustment Disorders.
In the substance-related and addictive disorders section of the DSM-5, how are the disorders separated and chategorised?
- Substance-use disorders.
- Substance-induced disorders:
a. Intoxication disorders.
b. withdrawal disorders.
c. Other substance/medication-induced disorders.
In the DSM-5, what are the two subtypes for PTSD?
- With dissociative symptoms.
- With delayed onset (if symptoms develop more than 6 months after the traumatic event).
What is the difference between Acute Stress Disorder and Adjustment Disorder?
Acute Stress Disorder is when an individual meets criteria for PTSD, but symptoms are experienced for less than one month (and more than 3 days).
Adjustment Disorder is when individuals meet criteria A for PTSD but not all other criteria OR they meet the other criteria but not criteria A.
What is one of the criticisms about Adjustment Disorder that we discussed?
That Adjustment Disorder pathologises “living”.
Do individuals with PTSD often have trouble learning, retaining, and recalling new information?
Yes.
What is a PTSD-related disorder that is included in the ICD, but is not included in the DSM-5?
What are dimensions of this disorder that a diagnosis of PTSD does not capture?
Complex PTSD.
Complex PTSD captures the emotional dysregulation, interpersonal dysfunction, and difficulties in self-identity that can develop as a result of recurrent, pervasive trauma, such as childhood neglect or recurrent abuse.
What are the two subtypes of PTSD?
PTSD with dissociative symptoms.
PTSD with delayed onset.
