What neurological conditions may be differentials for depression?
Parkinson’s, multiple sclerosis, dementia
What substances/drugs can be differentials for depression?
- CO poisoning can present with irregularities of the mental state
- substance misuse (alcohol, steroids, cannabis, cocaine, narcotics)
- centrally acting antihypertensives, lipi soluble beta blockers, CNS depressants, opioids, isotretinoin
What investigations can be done for depression?
- TFTs to exclude hypothyroidism
- electrolytes and serum calcium to rule out a metabolic disturbance
- blood count and ESR to rule out systemic infection or chronic disease
Give an example of a screening tool for depression.
PHQ-9: a 9-item self-administered diagnostic screening and severity tool based on current diagnostic criteria for major depression
What are possible complications of depression?
- exacerbation of pain, disability and distress associated with other conditions
- reduced QOF for patient and family
- increased morbidity and mortality in a range of comorbid conditions
- impaired ability to function normally
- increased risk of substance abuse
- complications associated with use of antidepressants
What is the prognosis for depression?
- with treatment, lasts 3-6 months
- 50% recover within 6 months and nearly 75% within the year
- recurrence likelihood is high
- persistent subthreshold symptoms progress to the full criteria for depression in 70% of people
How should patients with mild depression or people with subthreshold depressive symptoms requesting treatment be managed?
Period of active monitoring
- Discuss the presenting problems and any concerns they may have.
- Provide information about the nature and course of depression.
- Arrange follow up, normally within 2 weeks
How should people with persistent subthreshold depressive symptoms or mild-to-moderate depression be managed?
- consider offering a low-intensity psychosocial intervention
- group based CBT
- avoid routine use of antidepressants but consider for:
- history of moderate to severe depression
- subthreshold symptoms that have persisted
- persistence after interventions
- complicating care of a chronic physical health problem
How should people with moderate or severe depression be managed?
Offer an antidepressant and a high-intensity psychological intervention
What are common side effects of SSRIs?
- feeling agitated, shaky or anxious
- feeling or being sick
- indigestion
- diarrhoea or constipation
- loss of appetite and weight loss

- headaches
- low sex drive
- difficulty achieving orgasm during sex or masturbation
- in men, difficulty obtaining or maintaining an erection (erectile dysfunction)
What advise would you give patients receiving treatment?
- vigilant for worsening symptoms
- usually takes 2-4 weeks for symptoms to improve
- antidepressants should be taken for 6 months after remission of symptoms to prevent relapse
- antidepressants are not addictive
- may experience discontinuation symptoms if they miss doses (e/g/ sweating, restlessness, abdo symptoms, altered sensations)
What are different forms of low intensity psychological interventions?
- 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.
- Computerized cognitive behavioural therapy (CCBT) — this can be provided via a stand-alone computer-based or web-based programme and usually takes place over 9-12 weeks.
- Structured group-based physical activity programme — usually consists of 3 sessions per week of moderate duration (45 minutes to 1 hour) over 10-14 weeks.
What are different forms of high intensity psychological interventions?
- 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.
- Interpersonal therapy — duration and number of sessions is similar to CBT.
- Behavioural activation — duration and number of sessions is similar to CBT.
- Couples therapy — usually consists of 15-20 sessions over 5-6 months.
