Q

What is the difference between bonding and attachment?

A

Attachment - from infant to caregiver; foundation of how relationships will be to others in later adulthood

Bonding - flows from the caregiver to the infant (develops rapidly - due to oxytocin and breastfeeding etc; but can take longer if that took longer for you or if you had a traumatic birth)

Q

What is infanticide? What is the importance of the infanticide act?

A

Legally differentiates infanticide from manslaughter/murder (1922, amended 1983)

Infanticide - wilful act or omission which causes death of a woman’s child being under age of 12 months

“at the time of the act or omission the balance of her mind was distrubed by reason of her not having fully recovered from the effect of giving birth to the child or by reason of the effect of lactation”

Q

What scale can be used by midwives/health visitors to screen for derpression in a new mother?

A

Edinburgh Postnatal Depression Scale

5min test

Maximum score is 30 but 10 suggests depression

18
Q

What are the features of postnatal depression?

A

Ask about COGNITIVE rather than physical symptoms.

Similar to normal depression but particularly feelings of…

  • fatigue (NB: this is normal with a baby therefore focus on cognitive symptoms in new mothers)
  • irritability
  • anxiety.
  • Depressive cognitions often relate to the baby e.g. guilt or feeling like a failure as a mother
  • Recurrent intrusive thoughts about harming the baby may occur or obsessions or serious plan
19
Q

What are the risk factors for postnatal depression?

A
  • Biological - higher oxytocin levels mid-pregnancy are associated with early PND
  • Socioeconomic - unemployment
  • Younger age
  • Bad childhood - poor attachment with own parents, abuse
  • Poor social support
  • Previous pregnancy loss
  • Personality factors
  • Socially prescribed perfectionism
20
Q

How common is postnatal depression?

A

1 in 10 mothers affected in the year after birth

21
Q

When should you admit someone with postnatal depression?

A

Admit to MBU if:

  • severe depression
  • +/- suicidal ideation
  • +/- infanticidal ideation
22
Q

What is the prognosis with postnatal depression?

A

Most respond well to treatment within a month although some take longer and have difficulties for a year.

23
Q

What is the general management of postanatal depression?

A

Depends on risk assessment if treated at home or admission required. If supported at home…

Liaise with GP - ASAP

Support at home - health visitor, mental health input, childcare arrangements if necessary

Medication - analgesia if pain from obstetric complications, antidepressants if necessary. NB: analyse whether risk of suicide and if so then give shorter prescriptions.

Follow up - this should be longer than usually provided postnatally and needs to be assertive i.e. ensuring reminder letters are sent out and community midwives involved.

24
Q

What are the complications of postnatal depression for the baby?

A

Risk - infanticidal ideation

Attachment - affects baby’s attachment and may have long lasting effects on personality and development so early and effective treatment of PND is necessary.

25
Q

What are the features of maternal OCD?

A

Obsession = recurrent unwelcome thoughts /images /ideas or doubts.

Compulsions = related behavioural or mental acts to suppress or neutralise the distress or prevent a feared outcome

Causes significant functional impairment

26
Q

What are some examples of maternal OCD?

A
  • Fear of contamination - perceives a high risk of infection or of being poisoned
  • Thoughts or images of harming child
  • Thoughts or images of others harming their child
  • Thoughts of images of child being harmed by an accident
  • Repeatedly checking baby’s breathing or waking a sleeping baby for reassurance
27
Q

What screening questions can you use to assess maternal mental health?

A
  • How do you feel when you look at your baby?
  • Do you ever worry that there might be something wrong with them?
  • It can be difficult to look after a baby, do you ever feel that you cannot cope?
  • Are there times when they wont stop crying? How does that make you feel?
  • How do you picture things in a month’s time?
  • Do you ever wish you hadn’t had your baby?
  • Do you have any worrying thoughts about your baby?
28
Q

How many cardiac and birth defect occur without medication?

A

1 in 100 for cardiac defects

3 in 100 for birth defects

No medication is without risk

29
Q

Which part of pregnancy is most important to be careful with prescribing?

A

First trimester

30
Q

How does pregnancy affect pharmacokinetics/dynamics in pregnancy?

A

Blood volume increases between 30-50%

Baby pushes up diaphragm reducing residual volume and increasing respiratory rate

Increased progesterone (causing N&V and hypomobility of ureters)

Increased oxygen consumption

31
Q

Why is antipsychotic prescribing more risky in females?

A

Slower drug absorption, metabolism and excretion in women all lead to higher plasma levels and risk of SE

Women reach higher dopamine receptor occupancy compared to men at similar serum levels , since oestrognes increase dopamine sensitivity

Women overmedicated by default as most studies in men

Risk of overmedicating increases when sex hormones are high (e.g. ovulation and gestation) , whereas higher doses may be require at low-hormonal periods (e.g. menstruation and menopause)

32
Q

Are antidepressants safe in pregnancy?

A

No significant increased risk of congenital malformations or spontaneous abortion. SSRIs safe (sertraline 1st line). TCAs (amitriptyline, imipramine, nortriptyline) also safe but riskier in overdose (as cardiotoxic).

Clinical risk of discontinuing = relapse

Usually safer to continue during pregnancy than to stop and it is not recommended to stop antidepressants abruptly

33
Q

What are some complications of antidepressant use during pregnancy to the fetus?

A

Neonatology following delivery of baby for:

  • Neonatal withdrawal syndrome
  • Persistent pulmonary hypertension of the newborn
  • Cardiac malformation (Paroxetine SSRI)
34
Q

Are antipsychotics safe during pregnancy? What is a major risk with antipsychotics in pregnancy?

A

No significant increased risk of congenital malformations or spontaneous abortion.

BUT risperidone has 26% risk of cardiac malformations if taken in first trimester

All concentrations will DECREASE by third trimester (biggest effects with Quetiapine and Aripiprazole, no change in Olanzapine) so monitor dosing to prevent relapse

35
Q

Which antipsychotics are relatively safe during pregnancy?

A

Haloperidol, chlopromazine, olanzapine, quetiapine

NB: women have higher clozapine levels than men

36
Q

Which mood stabiliser would you never prescribe to women of childbearing age? What alternatives can be used?

A

Sodium valproate - teratogenic and contraindicated in all girls/women with child-bearing potential according to NICE (dose dependent)

BAP recommends olanzapine and fluoxetine

Refer to perinatal psychiatrist + prebirth planning meeting

37
Q

Are mood stabilisers safe during pregnancy?

A

Mood stabiliser use in early pregnancy may increase risk of malformations and affect neurodevelopment

Give 5mg folic acid (not usual 400mcg) from preconception until 12 weeks gestation to prevent this

38
Q

What is the relative infant dose (RID) of most medications regarded as acceptable in breastfeeding?

A

RID of 1-5% (up to 10%) regarded as acceptable

Don’t make the patient choose between meds and breastfeeding. Almost all drugs pass through breastmilk.

39
Q

Which psychiatric drugs can reduce lactation/milk supply?

A

Aripiprazole and promethazine can reduce milk

NB:Benzos can accumulate in the infant

40
Q

How does risk of postnatal depression and postnatal psychosis change with number of pregnancies?

A

Risk of postnatal depression stays the same with each subsequent pregnancy

Risk of postnatal psychosis decreases with each subsequent pregnancy

41
Q

Does pregnancy increase risk of mental illness?

A

No but period following birth does
