Emotionally
* can cause Dysphoria or Euphoria (and associated mood extremes)
Cognitively
* Abilities – e.g., disturbed concentration
* Appraisals – e.g., grandiosity & inflated self-esteem OR depressive /‘negative’ triad: hopeless view of self, environment, futur

Distinguishing depression & ‘normal’ sadness
Mood change is persistent and pervasive, not lifting even during enjoyable activities.
It may occur without a clear trigger or seem out of proportion to events.
The mood impairs daily functioning, affecting work, social life, or routine roles.
It’s accompanied by additional symptoms (cognitive, physical, or behavioural), not just sadness alone.
The quality of the mood differs from ordinary sadness — deeper and more enduring.
How was mood disorders conceptualised in the DSM-4 compared to the DSM-5
DSM-4
- The DSM dealt with depressive and bipolar disorders in one chapter called the mood disorders chapter
DSM-5
- In the DSM -5 the conditions were split up into deperate chapters. One focuses on depressive disorders and another for bipolar and related disorders
What is the common features of depressive disorder?
What is Major Depressive Episode/Disorder (MDE, MDD)
1 major episode in the absence of any history of manic episodes
A. An episode is ≥5 of 9 symptoms indicative of change over 2-week period; including either (1): depressed mood, or (2): loss of interest or pleasure.
PLUS
B. Cause significant distress or impairment
C. Not attributable to other disorders/substances
Criteria for Major Depressive Episode/Disorder
Depressed mood most of the day, nearly every day.
Loss of interest or pleasure in almost all activities.
Significant weight or appetite change.
Sleep problems — insomnia or oversleeping.
Noticeable restlessness or slowed movement.
Fatigue or low energy.
Feelings of worthlessness or guilt.
Poor concentration or indecisiveness.
Recurrent thoughts of death or suicide
MDE/MDD and Bereavement (grief)
DSM-IV: Excluded depression within 2 months of a loved one’s death (no MDE/MDD diagnosis).
DSM-5: Bereavement can cause deep grief but usually isn’t MDD. If both occur, symptoms may be more severe, recovery slower, and antidepressants may help those with underlying vulnerabilities. –> believed that people should be able to be diagnosed and that depression can develop after loosing a loved one
What is Persistent Depressive Disorder [PDD] (“Dysthymia”)
A more chronic, mild presentation
We would NOT diagnose PDD if:
What are some other depressive disorder?
Disruptive Mood Dysregulation Disorder
* Children 6-18 yo
* Chronic, severe, persistent irritability and frequent episodes of extremely out-of-control behaviour
Premenstrual Dysphoric Disorder (PMDD)
* Moved from DSM IV ‘further study criteria’ to a recognised condition in the DSM 5
* Severe form of PMS, characterized by mood lability, irritability, dysphoria, anxiety, difficulty concentrating, changes in appetite and sleep, pain, etc
What was Allen francizes most notable criticism in the DSM-5
Whatwas Allen francizes second most notable criticism in the DSM-5
Criticised taking out the bereavement clause in the DSM5
He believed that Normal grief will become Major Depressive Disorder,
What is the hallmark or primary feature of Bipolar Disorder
Primary impairment involving mood but with
a manic/hypomanic component
What are the three types of Bipolar?
Bipolar I [Depressive episode +]
* At least one manic episode
Bipolar II [Depressive episode +]
* Hypomania: episodes of increased energy, not severe enough to qualify manic episodes
* Severity and duration
Cyclothymia
* Chronic, but less severe form of bipolar
* Symptoms of mania and depression rather than ‘episodes’
What is a manic epsiode?
A. At least a week of (or any period of time if hospitalisation due to) abnormally & persistently elevated, expansive, or irritable mood and persistently increased goal-directed activity/energy: feature is present for most of the day, nearly every day of this period
B. 3 or more of the 7 symptoms (≥ 4 if mood is irritable)
C. Sufficiently severe to cause marked impairment in functioning, OR to necessitate hospitalisation, OR with psychotic features
D. Not attributable to effects of a substance or due to another medical condition
What are the manic episode criteria?
3 or more of these symptoms (or 4 if mood is ‘irritable’):
What is a Hypomanic Episode
Same symptoms as manic episode (3 or more) except:
* Lasts at least 4 consecutive days
* Unequivocal change in function but not severe enough to cause ‘marked impairment’ in function or trigger hospitalisation
What is Cyclothymic Disorder
*Numerous periods of hypomanic & depressive symptoms (not enough to meet criteria for episodes)
What is a specifier?
When diagnosing bipolar disorder, clinicians can add specifiers to describe additional features or patterns present in the condition. These specifiers provide more detail about the specific characteristics of the disorder.
What are common specifiers in Bipolar
With anxious distress
With mixed features
With melancholic features
With atypical features
With mood-congruent psychotic features
With mood-incongruent psychotic features
With catatonic features
With peripartum onset
With seasonal pattern
With rapid cycling (Bipolar I or II)
