Q

indications for the 4 different depression drugs (SSRI/SNRI’s/NaSSA)

A

Sertraline is considered safest in patients who have comorbid medical
conditions (especially if they have a history of ischaemic heart disease)

fluoxetine is the SSRI of choice in children and adolescents.

Mirtazapine is a noradrenergic and specific serotoninergic antidepressant (NaSSA) which has a sedating effect that helps improve sleep and stimulate appetite.

Venlafaxine is a serotonin– noradrenaline reuptake inhibitor (SNRI) which is usually used if SSRIs are ineffective or unacceptable.

58
Q

what are some things to cover in A for ASEPTIC in psych

A
  1. Appearance and behaviour - Provide some clues as to their lifestyle, current mental state and ability to care for themselves.

a. Age, gender, ethnicity and occupation – e.g. “Mrs X is a middle-aged Caucasian female who reported to be the lead singer of the Spice Girls”

b. Dress and self-care – dressing provocatively could be a sign of sexual disinhibition/bipolar disorder, whereas a disheveled appearance may be consistent with depression or schizophrenia. Note if the clothing is appropriate for the weather/circumstances and if the clothes have been put on correctly.

c. Manner - hostile/helpful, aggressive/amiable? Were they appropriately behaved with you during the consultation?

d. Posture and movement - were they tense, relaxed or overactive, or were there any side effects of antipsychotic use evident, e.g. tardive dyskinesia

e. Rapport - easy or difficult to establish, distracted or if they appear to be engaging with hallucinations (e.g. replying to auditory hallucinations in schizophrenia)
“This patient appeared well-kempt with adequate eye contact, a good level of personal hygiene and did not appear to be guarded.”

59
Q

give things you would include in S for aseptic in psych

A
  1. Speech - describe in terms of rate, rhythm, tone and volume. Comment on whether there was any pressure or poverty of speech and whether they were coherent or incoherent.

Think of speech as a train and thoughts as passengers – normal speech and thought would be a train travelling at normal speed, reasonably full of passengers and it takes a logical route from station A to station B.

NB: Formal thought disorder should be presented here, not in the Thought section, as it presents as abnormal speech patterns e.g. word salad

“The patient spoke coherently at a normal rate, and rhythm. However, their voice was quiet and monotonous. No obvious thought disorder.”

60
Q

Circumstantiality

A

is the inability to answer a question without giving excessive, unnecessary detail. However, this differs from tangentiality in that the person does eventually return to the original point.

61
Q

Tangentiality

A

refers to wandering from a topic without returning to it.

62
Q

Perseveration

A

is the repetition of ideas or words despite an attempt to change the topic.

62
Q

Echolalia

A

is the repetition of someone else’s speech, including the question that was asked.

63
Q

Knight’s move thinking

A

is a severe type of loosening of associations, where there are unexpected and illogical leaps from one idea to another. It is a feature of schizophrenia.

63
Q

Flight of ideas,

A

a feature of mania, is a thought disorder where there are leaps from one topic to another but with discernible links between them.

64
Q

Word salad

A

describes completely incoherent speech where real words are strung together into nonsense sentences.

65
Q

Neologisms

A

are new word formations, which might include the combining of two words.

66
Q

Clang associations .

A

are when ideas are related to each other only by the fact they sound similar or rhyme

67
Q

what to include in E for ASEPTIC in p[sych

A
  1. Emotion/Mood - represents a patient’s predominant subjective internal state at any one time as described by patient

a. Subjective – quote the patient directly e.g. “10/10” or “never felt better”
b. Objective – what you think their mood is e.g. “depressed,” “elated,” “euthymic”
flat affect = depressed
blunted affect = schizophrenia
c. Affect is what you observe of how the patient is presenting during the consultation in terms of emotions. Congruency means patient’s affect appears in keeping with the content of their thoughts. It is “incongruent” if the person’s report doesn’t match their presentation (i.e. they laugh while saying they have suicidal thoughts). If the affect varies appropriately, you can describe it as “reactive”
d. Risk assessment! See (8) but this is a common place to ask about risk to self, risk to others and risk from others

“Patient was feeling well and optimistic. He was having disturbed sleep which has recently resolved. Good appetite and has been motivated to go to the gym although he feels fatigue. No anhedonia, no evidence of worthlessness nor risks to self. Objectively, patient appeared to be euthymic but was blunted in affect”

68
Q

WHat is teh P for in ASEPTC

A
  1. Perception - hallucinations, pseudo-hallucinations, illusions, depersonalisation or derealisation.
69
Q

a. Content - thought insertion, thought withdrawal or thought broadcasting

b. Preoccupations (recurrent thoughts which the person is able to put aside), worries and overvalued ideas, obsessions, thoughts of harm

c. Delusions – grandiose, persecutory, hypochondriacal, nihilistic, of guilt, of reference, of infidelity, amorous, of control

d. Form - pressure or poverty of thought, thought blocking, loosening of associations, knight’s move, neologisms, perseveration, circumstantial or flight of ideas.

“On direct questioning, the patient denied paranoid thoughts and grandiose beliefs. No current auditory or visual hallucinations but in the past, he had omnipotent, threatening 2nd person auditory hallucinations which were distressing, as well as visual hallucinations of shadows”

If patient isn’t disclosing their hallucinations (e.g. if they’re paranoid): “On questioning, they denied experiencing any auditory or visual hallucinations but the patient was responding to unseen stimuli and seemed distracted”

70
Q

A
  1. Insight
    a. Does the patient consider themselves unwell in psychological terms?
    b. Does the patient feel in need of treatment?

78
Q

outline depression managmeent `

A

Summary
Mild depression or subthreshold depressive symptoms:
- Consider a period of active monitoring
- Provide information about depression
- Arrange follow-up within 2 weeks
Persistent subthreshold depressive symptoms or mild to moderate depression:
- Consider psychological intervention (patients can self-refer through IAPT)
- Avoid routine use of antidepressants (but consider if they have a history of moderate to severe depression, subthreshold depressive symptoms lasting a long time (usually >2 years) or mild depression that is complicating care of chronic physical health problems
Moderate or Severe Depression
- Offer an antidepressant and a high-intensity psychological intervention
First Episode of Depression
- Consider an SSRI (e.g. citalopram, sertraline)
Recurrent Episode of Depression
- Consider an antidepressant that the patient has previously had a good response to
- Avoid antidepressants that have previously failed
If co-existing chronic physical health problem
- Sertraline is preferred (lower risk of drug interactions)

  • If they develop psychosis: add the antipsychotic earlier on (whenever the psychosis comes on)
  • Stopping antidepressants: dose should be tapered down over a period of 2-4 weeks

Q

mx for schizophrenia

A
  • 1st line: atypical antipsychotic (e.g. quetiapine)

Q

what is serotinnin syndrome and when does it happen?

A

Serotonin syndrome is a constellation of symptoms caused by high levels of serotonin usually due to misuse of drugs that cause an increase in serotonin concentration (e.g. SSRIs).

It typically causes a fever, hypertension, tachycardia, agitation, diarrhoea, hyperreflexia, and myoclonus.

It tends to happen when two or more drugs that raise serotonin levels are taken together (in this case, sertraline and cocaine).

Other drugs that can cause serotonin syndrome include all classes of antidepressants, triptans, St John’s wort, lithium, metoclopramide, and other illicit drugs (e.g. ecstasy).
