Hx + MSE
Questionnaire - PHQ-9 i.e.
Bloods to rule out DDx: DDx: hypothyroidism, neurological disorders (Parkinson’s, MS, dementia), substances and adverse drug effects…
Blood glucose, U&E, creatinine, LFT, TFT, calcium levels; FBC, ESR
What is the mx of depression?
Subthreshold - Mild:
low-intensity psychological interventions, group CBT, avoid antidepressants
Moderate - Severe: antidepressant + high intensity psychological interventions
What are some low intensity psych interventions that we can use to treat depression?
Low-intensity psychosocial interventions are suitable for people with persistent subthreshold depressive symptoms or mild depression, and include:
Individual guided self-help, based on the principles of cognitive behavioural therapy (CBT) — this includes written material or other media relevant to reading age, and usually consists of 6–8 sessions (face-to-face and via telephone) over 9–12 weeks.
What are some high intensity psych interventions that can be used in depression?
Individual CBT — usually given over 16–20 sessions over 3–4 months. For people with severe depression, two sessions per week might be provided for the first 2–3 weeks of treatment.
What is the medication for depression?
SSRI - 1st line: citalopram,
fluoxetine, paroxetine, sertraline
FluoxeTEEN in teenagers!

What side effects can you get with SSRI’s and what do you need to know about prescribing them?
SSRIs side effects: hyponatraemia (SIADH) in elderly, nausea, headache, GI upset, sexual dysfunction, insomnia, agitation, restlessness, anxiety.
During the first few weeks of treatment, there is a potential increase for agitation, anxiety and suicide risk - especially younger patients.
In general, an antidepressant effect is usually seen within 2-4 weeks of starting treatment.
Treatment should be continued for at least 4 weeks (6 weeks if elderly) before considering switching.
Antidepressants should be taken for at least 6 months after they have recovered, to reduce the risk of relapse. People who are at high risk of relapse may need to take them for longer than this.
What are some other depression medications that are not SSRI’s?
- SNRI - Mirtazapine,
Venlafaxine, Duloxetine - Tricyclics - Amitriptyline (sedating), Imipramine (non-sedating). Anticholinergic SE.
- Monoamine oxidase inhibitors - Iproniazid, Phenelzine. SE - hypertensive crisis associated with certain ripe cheese
What are some other depressive disorders?
- Seasonal affective disorder
- Dysthymic disorder
- Postnatal depression
What is seasonal affective disorder? How do you treat it
Seasonal affective disorder is diagnosed if the person has episodes of depression which recur annually at the same time each year with remission in between (usually appearing in winter and remitting in spring). Management is light therapy, then SSRIs.
What is dysthymic disorder?
Persistent subthreshold depressive symptoms (sometimes termed dysthymia) is diagnosed if the person has:
Subthreshold symptoms for more days than not for at least 2 years, which is not the consequence of a partially resolved ‘major’ depression.
Mx: SSRI, CBT
Post natal depression? What do you know? how would you manage?
Postnatal depression affects about 13% of women after childbirth with suicide being the leading cause of maternal death postpartum. Peak occurrence is 3-4w postpartum - baby blues, on the other hand, commonly occur 2-3 days after birth and resolves within the first 2 weeks.
Paroxetine and sertraline are the drugs of choice for breastfeeding women.
