Q

Neurobiology of depression?

A

Decrease in serotonin and noradrenaline function- hence selective serotonin reuptake inhibitor are given.
Serotonin is affected by stress, generic factors and adverse childhood experience.

26
Q

Subgenual cingulate cortex?

A

Responsible in emotion regulation and processing

27
Q

HPA dysfunction?

A

Normally negative feedback of adrenal gland on hypothalamus.

Duxamethasone: a glucocorticoid, no negative feedback, still cortisol release.

Some glucocorticoid receptor alteration

28
Q

Neuroplasticity in depression?

A

Subcorticla volume changes in hippocampus etc in people with depression

Decrease in atypical dendrites, spine density, NMDA or AMPA receptors, synaptic proteins, neuronal atrophy

29
Q

Ketamine treatment?

A

NMDA receptor blocker, depression treatment.
Stimulates synaptogenesis
Modulates gaba and glutamate deficits

30
Q

Inflammation and depression?

A

Lupus and other immune disorders increase of depression. Could be cause of disability but we know stronger association than other disabling conditions.
Increased inflammatory markers Crps in people with depression and correlate with level of depression
TSPO translocator protein On microglia higher in people with depression, a marker of neuroinflammation

31
Q

Inflammation and serotonin?

A

Inflammatory pathways take away tryptophan to create inflammatory proteins and hence less to produce serotonin

32
Q

1st generation antidepressants?

A

Monoamine oxidase inhibitors (phenelzine and tranylcypromine) and tricyclic antidepressants amytryptilinw

33
Q

Monoamine oxidase inhibitors?

A

Phenelzine and tranylcypromine

Non selectively inhibit enzymes in breakdown of drops ins, serotonin and noradrenaline

34
Q

Tricyclics antidepressants?

A

Amytryptiline, clomipramine

Nonselectivley inhibit reuptake of monoamine such as dopamine, serotonin and noradrenaline

35
Q

2nd generation antidepressants?

A

SSRI, SNRI, alpha and serotonin antagonist, dopamine noradrenaline uptake inhibitor

36
Q

SSRI?

A

Sertraline, citalopram, escitalopram, fluoxetine and vortioxetine

37
Q

SNRI?

A

Venlafaxine and duloxetine

38
Q

Serotonin and alpha antagonist?

A

Mirtazapine

39
Q

Dopamine noradrenaline reuptake inhibitor?

A

Bupropion

40
Q

What is included in atypical depression?

A

Mood reactivity, significant weight gain or increase in appetite
Hypersomnia
Leaden paralysis

41
Q

Manic episode diagnosis?

A

Sufficiently sever to cause marked functional impairment or necessitates hospitalisation to prevent harm to self or other or there are psychotic features

42
Q

Dysthymia

A

Chronic form of depression

43
Q

Cyclothymia?

A

Mood shifts up and down from baseline but not as bad as bipolar 1 and 2

44
Q

What is age of onset on major depressive disorder?

A

25-35 years, but can be any age

45
Q

Probable bipolarity of depression will have?

A

Positive family history of Brad

Multiple episodes and early onset

46
Q

Proinflammatory cytokines induce?

A

Sickness behaviour

47
Q

Side effects of SSRIs?

A

Low toxicity safe, slow titration

Gastrointestinal symptoms
Headache irritability anxiety
Reduction in libido and sexual dysfunction

48
Q

Side effects of tricyclics?

A

Constipation, orthostatic hypotension dry mouth drowsiness cardiac toxicity

49
Q

MAOi side effects?

A

Dry mouth GI side effects, drowsiness, insomnia, food interactions, hypertension crisis

50
Q

Mirtazapine side effects?

A

drowsiness, sedation, hypotension, increased appetite and weight gain

51
Q

Bipolar disorder genes?

A

8-10% of 1st degree relatives

Amy-72-80
DZ-14

52
Q

Mitochondrial alteration in bipolar?

A

Reduced mitochondrial complex 1 in prefrontal cortex
Altered brain mitochondria morphology and distribution
Reduced mRNA for genes encoding ETC and antioxidants
Many SNPs of miti genes

53
Q

Central nervous system consumes how much oxygen?

A

20

54
Q

Phases of bipolar disorder treatment?

A

Short-term treatment
to reduce the severity and shorten the duration of the acute episode and achieve remission of symptoms

Long-term treatment
prevention of new episodes and to achieve adequate inter-episode control of residual or chronic mood symptoms

55

A

Lithium

Antipsychotics

Anticonvulsants

Antidepressants

56

Treatment of depressive disorders?

A

Antipsychotics
Fluoxetine/olanzapine combinations
Antidepressants with anti manic drug

Consider lamotrigine with an anti manic

57
Q

Treatment of acute manic episodes?

A

Dopamine antgonist e.g haloperidol olanzapine, respirdone

Valproate

Discontinue any antidepressant

58

What is long term treatment to prevent new episodes?

A

Lithium as initial mono therapy (0,6 to 0.8 mmol/l)

Alternatives are valproate, dopamine antagonist, carbamazepine

59

Toxicity
Narrow therapeutic index
Blood tests every 3 months for 1st year
