29
What is the stepped care model?
Helps with diagnosis + management of depression Begins at Step 1 and increases with severity (1) Assessment, support, monitoring, psychoeducation + referral for further assessment (2) For patients diagnosed with persistent sub-threshold depressive symptoms – low intensity psychosocial + psychological interventions + medications + further assessment + interventions (3) For persistent sub-threshold/ mild-moderate depression who have not responded to Step 2 interventions OR moderate-severe depression – medication + high-intensity psychological interventions + combined treatments + collaborative care (4) For severe + complex depression + risk to save life (severe self-neglect) – medication + high-intensity psychological interventions + combined treatments + multi-professional and inpatient care + crisis service
30
What is low-intensity psychosocial care?
Typically for persistent sub-threshold or mild to moderate depression (1) Guided self-help (2) Group physical activity programmes
31
What is group CBT?
Alternative to low-intensity psychosocial Used when low-intensity psychosocial interventions have been refused OR are not suitable
32
What is high-intensity psychological care?
For persistent sub-threshold/ mild-moderate depression (1) Where low-intensity psychosocial has failed OR (2) For use in moderate-severe depression (in combination with antidepressant)
33
What are some examples of high-intensity psychological care?
(1) Individual cognitive behavioural therapy – CBT (2) Interpersonal therapy (3) Behavioural couples therapy
34
Name 4 types of antidepressants.
(1) Monoamine oxidase inhibitors (MAOIs) (2) Inhibitors of monoamine uptake - Selective Serotonin Reuptake Inhibitors (SSRIs) - Tricyclics (TCAs) (3) Modulators of serotonin (5HT) receptors and other NT receptors (4) St John's Wort
35
What is the typical first line medication given for treatment of depression?
Selective serotonin reuptake inhibitors (SSRIs)
36
What are SNRIs?
Serotonin and noradrenaline reuptake inhibitors
37
What are NaSSas?
Noradrenergic and specific serotonergic antidepressant
38
What are SARIs?
Serotonin antagonist and reuptake inhibitor
39
What are SMSs?
Serotonin modulator and stimulator e.g. vortioxetine – inhibits reuptake serotonin (SERT) + modulates many 5HT receptors
40
What are NRIs?
Noradenaline reuptake inhibitor e.g. reboxetine
41
Give some examples of SSRIs.
(1) Sertraline (2) Fluoxetine (3) Paroxetine (4) Citalopram (5) Escitalopram
42
Why are SSRIs the preferred first line medication for the treatment of depression?
(1) Fewer side effects (2) No anticholinergic (3) Lack of toxicity in overdose (4) Less sedating than TCAs
43
What is venlafaxine?
SNRI Serotonin and noradrenaline reuptake inhibitor
44
What is mirtazapine?
Fewer interactions Fewer adverse events
45
What is trazodone?

53
What are RIMAs?
Subclass of MAOI Reversible inhibitor MAO-A Safer + fewer side effects than other MAOIs e.g. moclobemide
54
What is electroconvulsive therapy?
Associated with neuronal death – specific mechanism unknown For severe psychotic depression + bipolar disorder with psychotic symptoms
55
What is the important information for a patient when initiating therapy for depression?
(1) Full antidepressant effect takes time (e.g. 2-4 weeks) (2) Important to take as prescribed and continue after remission (e.g. 6 months+) (3) Possible side-effects (4) Potential interactions (5) Antidepressants are not addictive (6) Risk and nature of discontinuation symptoms with all antidepressants
56
What is the follow-up following initiation of therapy for depression?
Typically see patient after 2 weeks of initiation Every 2-4 weeks after for 3 months (may then extend)
57
What is mania?
Severe + recurrent psychotic affective disorder (1) Abnormally elevated mood, unwarranted optimism, exuberance, over-confidence, inflated self-esteem, hyperactivity, excessive libido and little sleep (2) Increased drive and extrovert behaviour but often socially tactless (3) Makes compliance problematic (4) Attacks last ≥1 week
58
What lasts longer, manic or depressive episodes?
Usually depressive
59

61
How are manic attacks normally controlled?
Sedative anti-psychotics
62
What is the long-term treatment for prophylaxis of bipolar disorder?
(1) Lithium (2) Anticonvulsants – e.g. sodium valproate (3) Other anticonvulsants – lamotrigine/ carbemazepine (4) Atypical antipsychotics – olanzapine or quetiapine (5) Benzodiazepines may be used short-term Antidepressants are not normally used
63
Why does lithium in the treatment of bipolar disorder require very careful monitoring?
Very narrow therapeutic window
64
Why are antipsychotics given in the treatment of bipolar disorder and mania?
Can give control of mania + some help to prevent relapse Mood stabiliser
65
What are some examples of antipsychotics given in the treatment of bipolar disorder and mania?
