While welcoming a new baby is a joyous milestone, the physical and emotional toll of recovery can sometimes spark serious mental health challenges. This complex reality captured national attention during the trial of Lindsay Clancy, a Boston-area mother whose case brought light to the extreme end of perinatal mood disorders. Prosecutors argued her actions were premeditated, whereas her defense maintained that she was suffering from severe, untreated postpartum psychosis when she harmed her three children in 2023.

To make sense of these conditions, it helps to view perinatal mental health as a broad spectrum. On one end are the common “baby blues” and postpartum depression, which affects about one in seven mothers with deep sadness, exhaustion and intense anxiety. At the far end sits postpartum psychosis, a rare psychiatric emergency affecting only one to two out of every thousand births that causes a person to lose touch with reality.

What is postpartum psychosis?

Perinatal mood and anxiety disorders comprise a spectrum of emotional and psychological disorders that can arise during or after pregnancy.

  • Postpartum “Baby Blues”: A temporary emotional upswing or downswing seen in up to 80% of new moms that goes back to normal within two weeks after the baby is born, according to Healthline.
  • Postpartum Depression (PPD): A moderate to severe clinical depression in which about 10-15% of mothers experience a persistent sad mood, low self-worth, high levels of fatigue, sleep problems and impaired infant bonding, per the Cleveland Clinic.
  • Postpartum Psychosis (PPP): As the European Society of Medicine notes, this is a serious psychiatric emergency with a sudden onset of mania, paranoia, bizarre delusions, auditory or visual hallucinations and severe confusion.

According to advocacy groups such as Postpartum Support International, postpartum psychosis is not always diagnosed because it is not a separate disorder in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), which can cause practitioners to misidentify the early signs.

What’s happening in your body

From pregnancy to the postpartum state, some of the most extreme and rapid neurochemical and endocrine changes in human physiology occur.

Dr. Justus Rabach, MD, tells Blavity Health, “Within 24 to 48 hours after giving birth, estrogen and progesterone levels decrease by over 90%, returning to pre-pregnancy levels. At the same time, there are marked fluctuations in the concentrations of thyroid hormones, cortisol and prolactin. These dramatic fluctuations in hormones in susceptible individuals throw the brain’s neurotransmitter systems off balance, particularly serotonin, dopamine and GABA receptors, which are involved in mood, stress responses and cognitive stability.”

With extreme sleep deprivation and the disruption of the circadian rhythm, these neurochemical changes can lead to deeply depressive episodes or acute psychotic breaks.

Causes of perinatal mood disorders

Postpartum depression and postpartum psychosis are not a reflection of either a lack of parenting skills or weakness on the part of the individual; it’s a combination of biological risk and environmental factors.

The National Institutes of Health (NIH) lists these as the main risk factors and causes:

  • Personal or Family History: If you have a history of major depression, postpartum depression or bipolar disorder, this greatly increases the chance of having mood disorders or postpartum psychosis.
  • Severe Sleep Deprivation: Chronic sleep fragmentation makes frontal lobe function worse and speeds up the process of emotional deregulation, confusion and paranoia.
  • Genetic Sensitivity to Hormones: Some women may be particularly sensitive to the normal postpartum drop in hormones at the cellular level due to inherited differences in their receptors.
  • Psychosocial Stressors: Lack of social support, family instability, financial pressures, trauma to the mother during birth or health issues with the infant bring tremendous psychological stress.

Is there a way to avoid postpartum psychosis?

Biological vulnerabilities may not always be preventable, but they can dramatically reduce the risk of developing postpartum psychosis through proactive clinical planning.

Perinatal psychiatrists create proactive postpartum prevention plans during pregnancy for women who are known to have risk factors. These strategies include starting mood-stabilizing drugs (prophylactic) as soon as possible after giving birth, while being carefully monitored by a psychiatrist. Moreover, creating a structured sleep plan and training partners or family members to handle evening and nighttime feedings, allowing the mother to get four to six hours of sleep per night, is an important physiological protective measure against psychotic breaks.

Health risks and complications

Postpartum mental health disorders, if undiagnosed and untreated, pose significant health risks to mother and baby.

Severe complications include:

  • Impaired Maternal-Infant Attachment: Severe postpartum depression can disrupt reciprocal bonding, leading to long-term cognitive and emotional developmental challenges for the child.
  • Chronic Depressive Illness: Untreated postpartum depression frequently transforms into long-term major depressive episodes lasting years.
  • Self-Harm and Suicide: Maternal suicide represents one of the leading causes of postpartum mortality in developed nations.
  • Infanticide and Acute Trauma: If postpartum psychosis is left untreated, the commanding auditory hallucinations or persecutory delusions (such as the infant is possessed or in danger) pose a catastrophic risk of unintentional or deliberate harm to the children and their mother.

What to do about perinatal mental health symptoms

When a person or the person you are close to is having more mood changes, intrusive thoughts and extreme fatigue after giving birth, it is important to take action immediately.

Avoid attributing any continued feelings of anxiousness or depression to fatigue. Please get in touch with your obstetrician/gynecologist, midwife or primary health care provider to have a formal screening for depression using the Edinburgh Postnatal Depression Scale (EPDS). Evidence-based treatments for postpartum depression include selective serotonin reuptake inhibitors (SSRIs), cognitive behavioral therapy (CBT) and new medications that are neuroactive steroids and directly impact GABA receptors (e.g., zuranolone).

Postpartum psychosis is a medical emergency; home remedies and outpatient talk therapy are not enough to treat symptoms of postpartum psychosis; inpatient psychiatric stabilization is necessary, and specialized pharmacotherapy treatment is required.

If you or someone you know is experiencing extreme postpartum anxiety, dark intrusive thoughts, or detachment from reality, immediate help is available. Call or text the 988 Suicide & Crisis Lifeline (dial 988), or call the National Maternal Mental Health Hotline at 1-833-943-5746 (1-833-9-HELP4MOMS) for 24/7, free, confidential support from trained perinatal specialists.

When to see a doctor

If the postpartum symptoms start to get worse or last longer than 14 days, medical help is needed immediately.

If a mother has any of the following symptoms, get emergency medical help immediately:

  • Bizarre behavior, talking rapidly or staying awake for days without feeling tired (hypomania/mania).
  • Expressing irrational beliefs, paranoia or suspiciousness of family members.
  • Hearing voices, seeing things that are not there or having strange tactile sensations.
  • Intrusive thoughts of harming herself, the baby or other children.
  • Inability to care for herself or distinguish reality from delusion.

Bottom line

The spectrum of postpartum mood disorders ranges from the frequent and common postpartum depression to the uncommon and life-threatening psychiatric emergencies such as postpartum psychosis. These biological conditions are characterized by dramatically reduced hormone levels and extreme lack of sleep, and must be clinically recognized rather than judged or dismissed. Early perinatal screening, early psychiatric intervention using mood stabilizing or antidepressant medications and good family sleeping support will help mothers recover safely and keep their families safe.

Frequently Asked Questions

Who is most likely to get postpartum psychosis?

Women with a personal or family history of bipolar disorder, schizoaffective disorder or a previous episode of postpartum psychosis face the highest clinical risk of developing the condition.

How long does postpartum psychosis last?

With immediate inpatient psychiatric care and proper medication, the acute phase of postpartum psychosis typically resolves within two to six weeks, followed by several months of ongoing treatment to achieve full recovery.
