Most Important Flashcards
Differentiation Between DMDD and Bipolar
- History of manic or hypomanic episode = bipolar
- Discerete obserbvable mood epidodes, “markedly different from baseline” = bipolar
- During manic episodes, cognition, behaviour and distractability get markedly worse in bipolar
- Irritability in DMDD is more stable and persistent
Differentiation between DMDD and ODD
- Persistent negative mood state between outbursts = DMDD
- Tend to be more mood symtpoms in DMDD than ODD
- Impariment in multiple settings = DMDD
- ODD-like presentations can occur in DMDD, but not vice-versa; if criteria for both are met, DMDD wins out
Differentiation between DMDD and Intermittent Explosive Disorder
- Severe outburts are present in both, but persistent irritability between outbursts = DMDD
- In some cases, Intermittent Explosive Disorder diagnosis can be made after 3 months, whereas 12 is needed for DMDD
Major Depressive Disorder Diagnostic Criteria
A. ≥5 of the following symptoms withing the same 2-week period, and at least 1 symptom is depressed mood or loss of interest/pleasure:
1. Depressed mood most of the day, nearly every day (subjective or observable)
2. Loss of pleasure/interest in most/all activities, most of the day, nearly every day (subjective or observable)
3. Significant changes in weight (≥5% of body weight, without dieting; failure to make expected weight gain in children) or appetite
4. Insomnia or hypersomnia nearly every day
5. Psychomotor agitation or retardation nearly every day (observable by others)
6. Fatigue or loss of energy nearly every day
7. Feelings of worthlessness or inappropriate guilt nearly every day (may be delusional in magnitude)
8. Diminished ability to think or concentrate, indecisiveness, nearly every day (subjective or observable)
9. Recurrent thoughts of death, recurrent passive suicidal ideation, active suicidal ideation
B. Clinically significant distress or impairment in social, occupational or other important areas of functioning.
C. Not attributable to medication, substances or a neurological condition.
D. At least one MDE is not better explained by schizoaffective disorder, or superimposed on a psychosis-spectrum disorder.
E. There has never been a manic or hypomanic episode
Differentiation between MDD and PDD
PDD requires depressed mood, more days than not, for at least 2 years (and no period of ≥2 months without depressed mood). Both can be diagnosed if criteria are met.

A. Depressed mood for most of the day, for more days than not (subjective or observable; in children and teens, mood can be irritable and duration = 1 year)
B. Presence, while depressed, of ≥2 of the following:
1. Poor appetite or overeating
2. Insomnia or hypersomnia
3. Low energy or fatigue
4. Low self-esteem
5. Poor concentration or difficulty making decisions
6. Feelins of hopelessness
C. During the 2 years, individual is never without A-B for ≥2 months at a time
D. MDD criteria may be continuously present for 2 years (in this case, MDD and PDD should be diagnosed)
E. No history of manic/hypomanic episode
F. Symptoms not better explained by psychosis-spectrum disorders
G. Symptoms not due to substances or medical condition
H. Symptoms cause clinically significant distress or impairment in social, occupational, or other important arears of functioning.

C. Not better explained by a depressive disorder that is not substance/medication-induced (e.g., symptoms preceeded substance/medication use)
D. Disturbance does not occur only in the context of delirium
E. Caused clinically significant distress or impairment
Note: this diagnosis should only be made instead of substance intoxication/withdrawal when A predominates the clinical picture and is sufficiently sever to warrant clinical attention.
Substance/Medication-Induced Depressive Disorder specifiers
Onset:

- In schizoprhenia, delusions show greater disorganization (less internally consistent)
- In delusional disorder, there is greater conviction, greater extension (i.e., the delusion is more tied to areas of the individual’s life) and greater pressure (i.e., preoccupation/concern)
Differentiation of Delusional Disorder from Mood Disorders and Schizoaffective Disorder
- If delusions occur exclusively during a major mood episode, then it’s likely not delusional disorder
- Mood symptoms may be present, but only relatively briefly compared to the delusions for delusional disorder to be appropriate (otherwise it would be other specified/unspecified schizophrenia spectrum and other psychotic disorder, accomparnied by other specified/unspecified depressive/bipolar disorder)

* With peripartum onset: If onset is during pregnancy or ≤4 weeks postpartum
Additional features:
* With catatonia
Severity (based on Clinician-Rated Dimensions of Psychosis Symptom Severity
Diagnosis can be made without a severity specifier
Differentiation of Brief Psychotic Disorder from other psychotic disorders
- If symptoms persist ≥1 monthm diagnosis is either schizophreniform disorder, delusional disorder, MDD/bipolar with psychotic features, or other specified/unspecified schizophrenia spectrum and other psychotic disrder
- Differentiation is challenging when symptoms have remitted in less than a month with successful treatment

1. No MDE or manic episodes have occurred concurrently with active-phase symptoms
2. If mood episodes have occurred with active-phase symptoms, they have been present for a minority of the total duration of the active and residual periods of illness
D. Not attributable to substances/medication/other medical condition.

D. Schizoaffective and mood disorders with psychotic features have been ruled out because either:
1. No mood episodes have occurred concurrently with active-phase symptoms
2. If mood episodes have occurred with active-phase symptoms, they have been presen for a minority of the total duration of the active and residual portions of the illness
