Q

Etiology of Depression

A
  1. Genetics
    - 40-70% chance of developing depressive episode if 1st degree relative suffer from depressive episode
  2. Organic
    - Cushing syndrome, Addison disease, Parkinson disease, stroke, epilepsy, coronary artery disease, thyroid
    - Medications
  3. Psychosocial Factors
    - Adversity in childhood
    — Maternal loss, disruption of bonding
    — Poor parental care
    — Physical / sexual abuse
    - Adversity in adulthood
    — Women: absence of a confiding relationship
    — Men: unemployment, divorce
    - Recent life events
    — Loss of a child
    — Death of a spouse
    — Divorce
    — Marital separation
    — Imprisonment
    — Recent death of a close family member
    — Unemployment
  4. Presence of cognitive errors
    - Magnification: tendency to magnify the magnitude of a failure and dismiss all previous successes
    - Overgeneralisation: generalisation of failure in one area of life to other areas of life
    - Personalisation: feeling that one is entirely responsible for failure and discounting the role of other individuals in responsibility for failure
    - Selective abstraction: choose to focus on negative aspects, forget positive aspects

DSM-5 Diagnostic Criteria for Depressive Disorder

At least __ of the following symptoms for a minimum duration of __ weeks

A

At least 5 of the following symptoms for a minimum duration of 2 weeks:

MSIGECAPS
1. Low mood for most of the days (core feature)
2. Anhedonia: Diminished interest (no derived pleasure) in almost all activities (core feature)
3. Weight loss, loss of appetite
4. Sleep difficulties
5. Psychomotor changes (agitation or retardation)
6. Low energy
7. Feeling worthless, or excessive guilt
8. Attention and concentration difficulties
9. Recurrent passive or active ideations of self-harm and suicide

+ Symptoms must cause marked impairments in terms of premorbid functioning

Q

Pros of Fluoxetine

A

Strongest, fastest response rate, highest chance of cognitive side effects

Conditions: Catatonia / NMS / Urgent response needed

63
Q

Electrode Placement - Bifrontal

A

Strong, fast response rate, lower chance of cognitive side effects, better for psychosis

Conditions: Schizophrenia / Psychosis

64

Milder, avoid directly stimulating L brain-memory and cognition, may require 1 or 2 more sessions

Conditions: Depression / Mania

65

66
Q

68
Q

Contraindications

A

- Foreign metal body in eye or cranium (excluding braces or dental fillings)

69
Q

Risk factors for seizures in rTMS

A
  • Personal or family history of epilepsy
  • Post-stroke or head injury with neurologic sequelae
  • Use of seizure-lowering threshold medications
  • Recent dose reduction of medication with anticonvulsant properties (eg. Benzodiazepines)
  • Neurologic disorders or medical conditions that may be associated with lowered seizure threshold
    eg. Sleep deprivation, raised ICP, substance withdrawal
70
Q

rTMS vs ECT

A

Both are neurostimulation methods that are effective for treatment of MDD

  • Patient profile recommended for ECT differ from those recommended for rTMS
  • rTMS response rates are poor in patients whom ECT has failed
  • TMS uses a magnetic coil to stimulate specific regions of the brain that are thought to play a role in depressions symptoms vs ECT uses electrical currents to induce a seizure in a sedated patient’s brain
71
Q

Current indications for rTMS

A

Depression
Post stroke rehabilitation for motor function

72
Q

Factors increasing seizure threshold

A

Male
Old age
Baldness
Paget disease
Dehydration

73
Q

Factors lowering seizure threshold

A

Sleep deprivation
Raised ICP
Substance withdrawal

74

- consists of: defining high risk situation
Behaviour: activity scheduling (for depressed) / relaxation techniques (mixed anxiety and depression)

75
Q

What is interpersonal therapy?

A
  • depression precipitated by interpersonal problems
  • improve interpersonal relationships
76
Q

Duration of depressive disorder (mild/severe/chronic)

A
