Perinatal Mental Illness

• Any mental health problem occurring in pregnancy or the first postnatal year

• All mental disorders of the age group

• How many women are affected ?

Page 3: Perinatal Mental Health - NW School of Psychiatry

Perinatal Mental Illness

• About 1 in 5

• What are the consequences of maternal mental illness in the perinatal period ?

Page 4: Perinatal Mental Health - NW School of Psychiatry

Maternal Mental Illness

Affects:

• Obstetric outcome

• Neonatal outcome

• Behavioural, emotional and physical development of the child

Classification in ICD 10 – perinatal mental disorders

Most disorders:

• Use codes from elsewhere in Chapter V (F) to classify mental disorder

• Add second code (F 99.3) – ‘mental diseases and diseases of the nervous system

complicating the puerperium’.

Sometimes : ‘F53 Mental and behavioural disorders associated with the

puerperium, not elsewhere classified’

This category should only be used if

• Onset is within 6 weeks of childbirth

• Insufficient information is available to make a diagnosis under another category

• Additional clinical features are present which make classification elsewhere

inappropriate.

• Includes postnatal depression NOS, puerperal psychosis NOS, other mental and

behavioural disorders associated with the puerperium, not elsewhere classified,

unspecified puerperal mental disorder

Page 10: Perinatal Mental Health - NW School of Psychiatry

Non-psychotic disorders in the perinatal period

Question :

At what stage of the perinatal period is depression most common ?

Page 11: Perinatal Mental Health - NW School of Psychiatry

Non-psychotic disorders in the perinatal period

• Point prevalence of major and minor depression in high income countries: 6.5 - 12.9 %

• Similar to non-perinatal women

• Higher prevalence in low and middle income countries

• No qualitative differences in psychopathology

• Thought content coloured by themes of motherhood

Page 12: Perinatal Mental Health - NW School of Psychiatry

Failure to bond

• Fetus or baby

• ‘He isn’t mine’, ‘it could be anybody’s child’, ‘I want her adopted’

• Extremely distressing

• Self blame, ‘what kind of person am I not to love my own child ?’

Mother – infant interaction

• Lower sensitivity of the mother towards the baby• Less interactive play• More negative comments

Page 13: Perinatal Mental Health - NW School of Psychiatry

Risk factors

Psychiatric • a past history of depression, anxiety, PTSD, substance

misuse, and neurotic personality traits

Psychosocial adversities• eg low socio-economic status -particularly in low and

middle income countries-, exposure to trauma, childhood sexual abuse, chronic and acute negative life stress, domestic violence, migration, relationship problems and low levels of social support

Page 14: Perinatal Mental Health - NW School of Psychiatry

Course

• 40 % risk of recurrence after subsequent birth (Wisner et al, 2004)

• Increased risk of non-perinatal episodes (Cooper and Murray, 1995)

Page 15: Perinatal Mental Health - NW School of Psychiatry

Anxiety disorders

• Period prevalence in pregnancy and postpartum no different (with exception of OCD) from non-childbearing women

• 12-13 % of women affected

• Commonly occur with other mental disorders, particularly other anxiety states, depression, bipolar disorder.

• Anxious thinking or ruminations often relate to serious harm coming to herself or the child, failing as a mother or being perceived by others as a poor mother

Page 16: Perinatal Mental Health - NW School of Psychiatry

Obstetric PTSD (Andersen et al, 2012)

• In the postnatal period, the prevalence is about 1-2 %

• The most important risk factors are subjective distress in labour and obstetric emergencies.

• May lead to avoidance of future pregnancies, or vaginal deliveries

Page 17: Perinatal Mental Health - NW School of Psychiatry

OCD (Russel and Mazamanian, 2013)

• Prevalence in perinatal period about 2 % (2 x increase)

• 1/3 OCD sufferers first become ill in pregnancy or after childbirth

• Thoughts - accidental or deliberate harm to the child –germs/knives/being a paedophile

• Resulting compulsive behaviour, avoidance

• Maternal sensitivity to child affected

Page 18: Perinatal Mental Health - NW School of Psychiatry

Eating Disorders (Easter et al, 2012, Micali, 2010)

• 2 % of pregnant women

• Often symptoms reduce but become more severe again after delivery

• Low birthweight

• 30 % have co-morbid depression after childbirth

Page 19: Perinatal Mental Health - NW School of Psychiatry

Personality Disorders

• 4.5 % of pregnant women (Bjoeresson et al, 2007)

• EUPD most common

• May worsen in perinatal period

• Little research

Page 20: Perinatal Mental Health - NW School of Psychiatry

Tokophobia

• Fear of childbirth

• Previous traumatic delivery or nullipara

• Risk factors – other mental illness, history of sexual abuse, poor social support

• High level of subjective distress

• Requests for Caesarean Section

Diagnosis and relative risk of admission

after childbirth in first time mothers

Page 23: Perinatal Mental Health - NW School of Psychiatry

Presentation

- Puerperal mania -

• Friedrich Osiander (1769)

• Abrupt onset

• Very severe symptoms

• Rapid escalation

• Highly disorganized speech, extreme excitement or excitation

• Abnormal thought content related to motherhood (eg baby still in

womb, woman is Virgin Mary, baby is Jesus Christ, baby can fly)

• High risks to mother and baby

Page 24: Perinatal Mental Health - NW School of Psychiatry

Psychotic depression

• Typical and severe symptoms

• Mutism, stupor

• Content of delusions and abnormal perceptions

dominated by motherhood themes, eg. unworthy mother,

baby is devil, baby needs to be protected from

persecutors

• No bonding: ‘He isnt mine, I want him adopted’, ‘she

could be anybody’s child’

• High risks to safety of infant and mother

Page 25: Perinatal Mental Health - NW School of Psychiatry

Other common features of

puerperal affective psychosis

• Perplexity

• Confusion

• Changing delusions

• Similar to symptoms of cycloid psychosis –

but often develops into bipolar disorder

Page 26: Perinatal Mental Health - NW School of Psychiatry

Postpartum psychosis – a psychiatric emergency !!!

• Rapid onset

• Rapid escalation

• The most florid and severe type of psychosis

• On call staff need to be very suspicious of incipient

mood symptoms and oddities in presentation – if

called to maternity ward assessment by experienced

psychiatrist within 4 hours ! (NICE, 2014)

Page 27: Perinatal Mental Health - NW School of Psychiatry

Recurrence of puerperal affective psychosis

• 54.4 % of women with a past history of PPP experience

another severe episode after the next delivery

Page 28: Perinatal Mental Health - NW School of Psychiatry

Perinatal course of bipolar disorder

• In pregnancy the course probably slightly improves but

high risk of relapse if medication is discontinued

Page 29: Perinatal Mental Health - NW School of Psychiatry

Relapse of Bipolar Disorder during Pregnancy

in Dependence on Medication

Viguera, et al , Am J Psychiatry, 2007

Page 30: Perinatal Mental Health - NW School of Psychiatry

Postpartum relapse in bipolar disorder

• About 1 in 2 develop a

recurrence in the early

postpartum period

• In 1 in 5 the episode is

severe

Page 31: Perinatal Mental Health - NW School of Psychiatry

“My family has a grand tradition…… after a woman gives

birth, she goes mad."

• Evidence for familiality of the

postpartum trigger in bipolar

families• Jones and Craddock, Am J Psych

2001

Page 32: Perinatal Mental Health - NW School of Psychiatry

Schizophrenia and childbearing

Questions:

Fertility ?

Social background factors ?

Page 33: Perinatal Mental Health - NW School of Psychiatry

Schizophrenia in the perinatal period

• Only disorder where fertility is still reduced

• Higher rate of childhood abuse and domestic violence

• High rates of co-erced sex and sexual risk taking

• Less contraceptive use and more unwanted pregnancies

• Disorder with the highest involvement of social care

Page 34: Perinatal Mental Health - NW School of Psychiatry

Schizophrenia

Risk of postpartum relapse / worsening increased

• if there is an admission in pregnancy

• where there is partner psychopathology

• Discontinuing medication in pregnancy

Pressures of becoming a mother, increased contact with health and social care professionals, disruption of routine, new cognitive demands

• 62% mental health female population violent suicide*

• Violent deaths more common in all time periods throughout

pregnancy and postnatal year

*NCISH, personal communication

Page 41: Perinatal Mental Health - NW School of Psychiatry

Diagnosis

• Sufficient information to make a diagnosis in 78/101 women

• Most (57) had a recurrence of pre-existing mental disorder –

most commonly recurrent depressive disorder (45)

• 2 had prior bipolar diagnosis

• 2 had prior schizophrenia diagnosis

• 22 women had psychotic symptoms

• 14 women had additional substance misuse diagnosis

Page 42: Perinatal Mental Health - NW School of Psychiatry

Red flag clinical features

• Recent change in mental state or new symptoms

• New thoughts or acts of violent self harm

• Feelings of incompetence as mother

• Feeling estranged from the child

Page 43: Perinatal Mental Health - NW School of Psychiatry

Key recommendations to reduce suicide

• Improve the effectiveness of communication between health and other agencies

• Raise awareness of mental illnesses in the perinatal period

• Provide additional training to all involved health professionals

• Set up regional clinical networks for perinatal mental health with all stake holders

Identification pregnancy and postnatal period:

All health professionals should consider asking the following depression identification questions as part of a general discussion about mental health and wellbeing:

During the past month have you often been bothered by :

• feeling down, depressed, or hopeless?

• having little interest or pleasure in doing things?

Also consider asking about anxiety using the GAD scale - 2:

during the past month have you been:

• feeling nervous, anxious, or on edge?

• unable to stop or control worrying?

Page 50

Page 51: Perinatal Mental Health - NW School of Psychiatry

Further assessment

If the woman answers yes to any of the above questions, or where there is clinical concern, further assessment is needed :

As part of full assessment, consider using formal measures such as the patient health questionnaire (PHQ-9), the Edinburgh Postnatal Depression Scale (EPDS) or GAD-7 and referral to a general practitioner or mental health professional, depending on the severity of the presenting problem.

At all subsequent contacts during pregnancy and the first year after birth, the health visitor and other healthcare professionals who have regular contact with the woman should consider asking the two depression questions and using GAD-2 as well as the EPDS or the PHQ-9 as part of monitoring

Page 51

Page 52: Perinatal Mental Health - NW School of Psychiatry

Identification – severe mental illness

At a pregnant woman’s first contact with services, ask about

• any past or present severe mental illness

• previous or current treatment

• any severe postpartum mental illness in a first degree relative

If alcohol misuse is suspected, use the alcohol use disorders identification test (AUDIT) as an identification tool in line with the NICE guideline on alcohol use disorders.

If drug misuse is suspected, follow the recommendations on identification and assessment in the NICE guideline on drug misuse—psychosocial interventions.

Page 52

Page 53: Perinatal Mental Health - NW School of Psychiatry

Referrals for psychological treatment

Assess all women with a known or suspected mental health problem who are referred in pregnancy or the postnatal period for psychological treatment within two weeks of referral

and provide psychological interventions within one month of initial assessment.

Page 53

Page 54: Perinatal Mental Health - NW School of Psychiatry

Assessment and referral - severe

Refer all women who have, are suspected to have, or have a history of severe mental illness to a secondary mental health service (preferably a specialist perinatal mental health service) for assessment and treatment, and ensure that the woman’s GP knows about the referral.

Page 54

Page 55: Perinatal Mental Health - NW School of Psychiatry

Assessment and referral – postpartum psychosis

If a woman has suddenonset of symptoms suggesting postpartum psychosis, refer her to a secondary mental health service (preferably a specialist perinatal mental health service) for immediate assessment (within four hours)

Page 55

Page 56: Perinatal Mental Health - NW School of Psychiatry

Principles of perinatal management

Page 57: Perinatal Mental Health - NW School of Psychiatry

• Referral to psychiatrist as soon as pregnancy is known

• Data on medication safety change all the time – perinatal psychiatrist would be ideal, if available.

• Prioritize appointment

• Invite partner / significant other

• Detailed forensic style assessment, including assessments of risks and likely parenting competence

Principles of management in pregnancy(moderate – severe mental illness)

Page 58: Perinatal Mental Health - NW School of Psychiatry

• Plan antenatal and postnatal care as early as possible

• Check woman has booked with antenatal clinic

• Be aware and discuss potential risks of comorbidities to pregnancy and child outcome

Overall management in pregnancy

Page 59: Perinatal Mental Health - NW School of Psychiatry

• Identify risk factors for recurrence of mental illness, particularly for the postnatal period

• Optimize non-pharmacological treatments

• Talking therapy – to be provided within 1 month of assessment ! 1

• Discuss how to reduce postnatal stress, optimize sleep, and mobilize postnatal support

• Liaise with midwives, health visitors, child social workers

• Multi-disciplinary and multi-agency meetings

Management in pregnancy

Page 60: Perinatal Mental Health - NW School of Psychiatry

• Often > 1 planning appointment needed

• Write one multi-disciplinary care plan

• Care plan for intrapartum and postnatal period should be ready at least by 32 week gestation

• Distribute plan to all involved professionals

• Copy in handheld maternity notes

Management in pregnancy

Page 61: Perinatal Mental Health - NW School of Psychiatry

• There are no risk-free management options !

• Discuss risks and benefits of medication options to mother and child :continuing

stopping

restarting before delivery/ day 1 postnatal etc

Also discuss risks of untreated illness !

• Avoid drugs with higher teratogenic risk

• Avoid drugs with the least safety data

• But !!! Important are … past response to treatment experience of side-effectswoman’s preference

Prescribing in pregnancy

Page 62: Perinatal Mental Health - NW School of Psychiatry

• Avoid abrupt discontinuation when pregnancy is discovered

(unless it is valproate !)

• Avoid poly-pharmacy

• Avoid higher doses, but do not undertreat !

Prescribing in pregnancy

Page 63: Perinatal Mental Health - NW School of Psychiatry

• Record discussions in case notes

• Copy clinic letters to patient

• Advise on other resources for information on reproductive safety of psychotropic medication

• Inform obstetrician and midwife of medication

• Any changes to medication plan by other doctors or pharmacist should be discussed with psychiatrist beforehand

Prescribing in pregnancy

Page 64: Perinatal Mental Health - NW School of Psychiatry

• Patient should bring psychotropic medication into hospital

• Withdrawal symptoms in neonate commences usually within 48 hours of delivery

• Offer 2-3 day stay on postnatal ward for paediatric observations

• Pre-discharge meeting on maternity ward

• Ensure community midwife and health visitor know about maternal psychotropic medication and possibility of neonatal withdrawal after early discharge

Management in pregnancy

Page 65: Perinatal Mental Health - NW School of Psychiatry

• Acute onset + rapid escalation

• Postpartum psychosis is a psychiatric emergency !

• Approximately 50 % of cases are first episodes

• Incipient symptoms often missed: ‘Stressed and tired’Fluctuating symptoms ‘The blues’Woman conceals symptoms

• High level of awareness needed by maternity and on call mental health staff !

• If suspected, mental health team needs to assess within 4 hours1

Psychosis after delivery

1National Institute of Health and Care Excellence (2014). Clinical guideline 192

Page 66: Perinatal Mental Health - NW School of Psychiatry

• Lower threshold for admission

• Admit to Mother and Baby Unit if available

• High risks – effective medication regime and frequent reviews essential

• Choice of medication less restricted

Postpartum psychosis

Page 67: Perinatal Mental Health - NW School of Psychiatry

WHO, 2003 :

‘ Infants should be exclusively breastfed

for the first six months of life.

Thereafter, to meet their evolving

nutritional requirements,

infants should receive nutritionally

adequate and safe complementary foods,

while breastfeeding continues for up to

two years of age or beyond.’

World Health Organization. Global strategy for infant and young child feeding. Geneva, 2003, World Health Organization. Available at: http://www.who.int/child_adolescent_health/documents/9241562218/en/index.html.

Breastfeeding

Page 68: Perinatal Mental Health - NW School of Psychiatry

• All psychotropic drugs are transferred into breast milk

• Exposure of child during breastfeeding is usually much less than during pregnancy

• Few data for most psychotropic drugs

• Measure of exposure : relative infant dose (RID):

infant dose/kg bw : maternal dose/ kg bw

• RID < 10% regarded as ‘relatively safe’ (Bennett, 1996) 1

• Most psycho-tropics are well below 10 %, but some exceptions

1Bennett PN (1996) Use of monographs in drugs. In: Bennett PN (Editor), Drugs and Human Lactation (pp 67-74). Amsterdam: Elsevier Science Publishers

Psychotropic drugs and breastfeeding

Page 69: Perinatal Mental Health - NW School of Psychiatry

• In general adult practice sexual health, fertility, planning for parenthood, and contraception should be discussed with all women of childbearing potential, aiming at once a year.

• Offer preconception counselling to women who plan a pregnancy

Women with childbearing potential

…….Contraception should be used

on every conceivable occasion……….

Spike Milligan, 1972

Page 70: Perinatal Mental Health - NW School of Psychiatry

• All psychotropic drugs pass through placenta

• The degree varies between drugs

• Randomised, double-blind controlled trials are not ethical

• Next best levels of evidence:

pregnancy registers, population studies, cohort studies,

case control studies

Investigating whether a drug is harmful to the developing child

Page 74: Perinatal Mental Health - NW School of Psychiatry

• Depends on question and size of risk

• Major anomaly rate

3 % in general population:

1,000 exposed cases needed to test for doubling of risk1

Studies now can answer question for many psychotropic drugs as groups (antipsychotics) or individual agents (antidepressants and some antiepileptics)

• Specific anomalies

If anomaly has incidence of 0.1 % in general population (eg cleft palate): almost 11,000 exposed cases needed to test doubling of risk2. Studies on antidepressants can now answer question for some specific anomalies

Sample sizes needed to test for congenital anomalies

Page 75: Perinatal Mental Health - NW School of Psychiatry

• No consistent approach to confounding factors

• Little known about untreated maternal illness

• Epidemiological studies – large numbers but lack of accuracy in neonatal diagnoses

• Diagnostic bias when assessing pregnancy and infant outcome

• Multiple statistical tests per study

• Research difficult to do !

Two population-wide studies from Sweden1,2

• Incidence of GDM almost two-fold increased (odds ratios: 1.78, 1.77; 1.94)

• Effect of olanzapine/clozapine no greater than other antipsychotics taken together2

• In one study early pregnancy weight was accounted for and effect just dropped below significance level2

• No effect of antipsychotic exposure on fetal growth parameters,except formacrocephaly in olanzapine/clozapine group (OR: 3.02, CI: 1.60-5.71)2

Summary for antipsychotics

• Current evidence does not suggest that antipsychotics are major teratogens.

• Suggested increase of MCMs associated with risperidone is very small

• Association with a small increase in pre-term birth and babies small for gestational age. True effect or confounding factors ?

• Possibly small increase in still-births

• Uncertain association with gestational diabetes.

• There is no indication for any significant long-term neurodevelopmental effect

More research with larger samples and adequate control for confounding factors is needed !

Teratogenic effects of anti-epileptic drugs

• Evidence exclusively from studies of women with epilepsy

• Valproate is associated with a 3-fold increase of major congenital malformations – consistent finding1,2

• Carbamazepine has been associated with a 2-fold increased rate of major congenital anomalies3,4

• Malformations not due to seizure activity in pregnancy5

• Some dependence on dose, but reported critical thresholds vary widely6

• Lamotrigine – studies have not found teratogenic effect2,4,7 except for one8

• Little data on pregabalin

Folate supplementation–is it preventative ?

• Evidence from general population studies and high risk families that folate (taken 3 months before and after conception) reduces incidence of congenital defects significantly.

• In women taking anti-epileptics (pregnancy registers and reviews)1,2,3,4,5

Effect at best uncertain. No protection seen in some studies.

Preventative effect of neurodevelopmental impairments unknown.

Summary for anti-epileptics

Valproate • Has widespread teratogenic and neurodevelopmental effects on offspring, • Harm throughout pregnancy• There is no safe time and no safe dose • Folate does not protect

Carbamazepine• General increase of malformations. Smaller risk of spina bifida than valproate

Lamotrigine• Current literature does not suggest that teratogenic effect is likely

Lithium

Recent prospective study with untreated bipolar control group1 :

• Risk of cv anomalies after 1st trim exposure 4.1% (5/123) vs non-exposure 0.6 % (4/711) (p<0.005)

• When spontaneously resolving anomalies excluded: no difference

• Higher rate of pre-term delivery (2-fold increase)

European lithium study

Case control study for Ebstein anomaly1 :

• Surveillance of 5.6 million births• 15 congenital anomaly registers in European countries• 264 Ebstein cases – none exposed to lithium• 9/264 exposed to maternal mental illness – Ebstein

associated with MI rather than lithium ?

Summary: It is unlikely that lithium causes Ebstein anomaly. A small effect on general cv anomalies cannot be excluded at present.

• Avoid agents with few data, eg paliperidone , lurasidone

• ‘Do not offer depot antipsychotics to a woman who is planning a pregnancy, pregnant or considering breastfeeding, unless she is responding well to a depot and has a previous history of non-adherence with oral medication’ (NICE, 2014)1

Prescribing in preconception or pregnant patients : 1. Antipsychotics

1. National Institute of Health and Care Excellence (2014) Clinical Practice Guideline 192

Page 105: Perinatal Mental Health - NW School of Psychiatry

Antipsychotics and dysglycaemia

– Consider impact of anti-psychotic induced weight gain on pregnancy and infant outcome

– Consider other risk factors for gestational diabetes, (1st degree relative has type 2 DM, ethnicity, previous macrosomic baby, previous gestational diabetes) when choosing antipsychotic agents in pregnant women and women with childbearing potential

– Discuss weight management

– Every woman taking antipsychotics in pregnancy

should be screened for gestational diabetes1

(including oral glucose tolerance test at 24-28 weeks

of pregnancy2)

2. Prescribing anti-epileptic drugs :

Valproate:

NICE1

• Do not offer valproate for acute or long-term treatment of a mental health problem in women who

• are of childbearing potential• Plan a pregnancy• Are pregnant• Consider breastfeeding1.

MHRA (2015)2,3

• Can be prescribed to a woman of childbearing potential only in exceptional circumstances, if there is no alternative and if she is taking effective contraception

• She needs to be aware of the risks and be on effective contraception.

2. Prescribing anti-epileptic drugs :

Carbamazepine:

• Do not offer carbamazepine to women who are planning a pregnancy or are already pregnant 1

Lamotrigine:

• Most studies find no increase in oral clefts. Use cautiously.• Serum levels decline in pregnancy • Monitor blood levels from early pregnancy into postnatal period• Mood diaries !!!

Page 109: Perinatal Mental Health - NW School of Psychiatry

• The teratogenic risk of lithium is low but less researched than for antipsychotics.

• In a preconception or pregnant woman in the 1st trimester already taking lithium, a need to switch to an antipsychotic is less compelling. Patient can stay on lithium she needs a mood stabilizer and has responded to lithium.

• If the woman requires a second mood stabilizer in addition to an antipsychotic this should be either lithium or lamotrigine and not valproate or carbamazepine

3. Prescribing Lithium

Page 110: Perinatal Mental Health - NW School of Psychiatry

Pregnancy

• Levels tend to fall

• Measure frequently, particularly in month before expected delivery date1

• NICE (2014)1 recommends: 1 x / month up to week 36 of pregnancy

1 x / week in month before expected delivery date

Adjust lithium dose

Treatment with lithium

1National Institute of Health and Care Excellence (2014) Clinical Practice Guideline 192

Page 111: Perinatal Mental Health - NW School of Psychiatry

Delivery

• Delivery in hospital 1

• Obstetrician-led care 1

• Stop lithium when labour starts

• Measure level 12 hours after the last dose 1

• Monitor lithium level, fluid balance, and electrolytes during delivery 1

Postnatally

• Monitor baby for side-effects

• If lithium level in therapeutic range, continue with pre-pregnancy dose. Check level after one week

Treatment with lithium in pregnancy

1National Institute of Health and Care Excellence (2014) Clinical Practice Guideline 192

• Avoid

• Low dose quetiapine as alternative

4. Treatment with anxiolytics and hypnotics

Page 113: Perinatal Mental Health - NW School of Psychiatry

Breastfeeding

• Antipsychotics:

o Avoid clozapine (agranulocytosis)

o NICE1 : do not offer depot antipsychotics unless the woman

is responding well to a depot and has a previous history of

non-adherence with oral medication.

• Mood stabilizers:

o Don’t offer lithium

o Don’t offer valproate and carbamazepine1

• Antidepressant

o Previous response is important

o In first onsets, prefer agents with more data

Breastfeeding

• Z-drugs Short-term use only

Recommendation – don’t breastfeed during the night

• Trazodone Breastfeeding compatible if dose < 100 mg1

General advice to mother:

• Monitor baby for side effects (sedation, muscle tone, other side-

effects) – if in doubt discuss with community midwife/health visitor/ GP if in doubt
