To The Editor,
The current COVID-19 pandemic is causing severe damage to the mankind through direct
impact on health and also collaterally affecting all aspects of life including the
mental health. The impending mental health crisis has attracted the attention of global
experts and organisations necessitating the documentation of impact of COVID-19 on
mental health especially among the vulnerable populations (Tandon, 2020). Pregnancy
and the postpartum period are known to have increased vulnerability to psychiatric
disorders (Eberhard-Gran et al., 2002). Earlier studies reported the association of
other coronaviruses with a range of psychiatric disorders (Cheng et al., 2004; Severance
et al., 2011). However, there is no information on new-onset psychosis in asymptomatic
patients or post-partum women with COVID-19. We report three cases of post-partum
psychosis (PP) associated with asymptomatic COVID-19 managed at Topiwala National
Medical College (TNMC) & B. Y. L. Nair Charitable Hospital (NH). NH is a an academic
tertiary care public hospital and a dedicated COVID-19 hospital in Mumbai, India,
receiving referrals from all over the Mumbai Metropolitan Region (MMR)(Mahajan et
al., 2020). In the initial phase of three months of COVID-19 pandemic (from 4th April
2020 to 31st July 2020), NH treated three asymptomatic, RT-PCR confirmed COVID-19
women with PP. The demographic, clinical characteristics, delivery details and management
of COVID-19 mothers with PP are described in Table 1
. This study was approved by Institutional Ethics Committees of TNMC, Mumbai and ICMR-National
Institute for Research in Reproductive Health, Mumbai.

Psychosis Symptoms
DOP, DOR, agitated behaviour SHB (suspiciousness that people are trying to harm her),
AH (various unknown voices), reduced sleep and loss of appetite, severe fearfulness
(drank two sips of methylated spirit in an attempt commit suicide)
DOP (suspicious of doctors and nurses around her that they were trying to make her
and her child COVID-19 positive), aggressive behaviour towards hospital staff, belief
that she was COVID-19 negative. Belief of doctors informing all other patients to
stay away from her, Believed that people are keeping an eye on her, believed her conversations
are being traced, loss of appetite as she felt she was being poisoned
IOR, guilt (people are blaming her for COVID-19), IOP and harm to baby, abusive behaviour
without any provocation, had put talcum powder in the mouth and eyes of her baby.
Fearful that she being scanned and passing this information to doctors. She felt that
other people are discussing about her and blaming her COVID-19 spreader.

All three women had uneventful deliveries (two caesarean deliveries and one normal
vaginal delivery) and gave birth to healthy new-borns (Table S1). They developed PP
within seven days of giving birth (mean 5 days). Their other laboratory investigations,
neurological work-up and general examination was normal. Diagnosis of PP was based
on the presence of psychotic symptoms in the absence of other organic or mood disorders.
All women recovered within seven days of treatment and were discharged. Duration of
symptoms lasted till seven days in two patients and three days in one patient. Two
patients received haloperidol, trihexyphenidyl and third patient was given olanzapine
(Table 1).
Post-partum mothers are vulnerable to a number of psychiatric disorders, owing to
physiological and psychological changes happening in the mother’s body(Brockington,
2004) Our patients had only psychogenic type of PP, as affective symptoms were characteristically
absent in all three cases. However, prospective studies are required to generate robust
data on association of PP with COVID-19. Affective symptoms have been shown to occur
in majority of the cases and many cases present with rapid mood fluctuations(Brockington,
2004). Onset of illness in all the three cases were in the first week following delivery.
The most common symptoms in our cases were delusion of persecution and reference,
which have been shown to be the most common in other studies as well (Regmi et al.,
2002; Sit et al., 2006). Two women in our series, had delusion surrounding the SARS-CoV-2
infection, which goes in favor of psychogenic rather than a structural cause. This
could be due to added stress surrounding COVID-19, as stress is known to be one of
the main factors in development of PP. Aggression has also been noted in PP and was
present in all of the cases. Around 35% of the women with PP pose a risk to their
infant(Sit et al., 2006) (. Two women required separation of infant from mother and
one required supervision. A sense of well-being and hypomanic symptoms have frequently
been shown to occur in prodrome of PP(Sit et al., 2006) (, however none were seen
in our series. Established risk factors that were evident in our sample were parity
(two primipara), CS (two) and gestational hypertension (one). First pregnancies and
preeclampsia are greater psychosocial stressor. It has also been hypothesized that
biological factors could be in play (Blackmore et al., 2006) Neuropsychiatric manifestations
like depression, anxiety and psychosis of COVID-19 infection are accounted to a hypercoagulable
state(Troyer et al., 2020). Infection or treatment with steroids was not present in
our patients, ruling them out, as the cause(Valdés-Florido et al., 2020) (. Delirium
was ruled out in all of our cases.
An important stressor is social isolation. Usually, new mothers are supported by their
families during the stressful puerperium in India. Social isolation in SARS-CoV-2
causing psychosis has been documented(Brown et al., 2020). Women with first episode
of PP have demonstrated elevations in IL-6, thereby supporting the immune mediated
mechanism in PP (Sathyanarayanan et al., 2019). A profound inflammatory response to
SARS-CoV-2 infection, known as ‘cytokine storm’ has been described and has been hypothesized
to play a role in neuropsychiatric complications(Troyer et al., 2020). Raised antibody
titers against HCoV was observed in recent psychotic episode( HYPERLINK \l "Ref9"
\o "Severance et al., 2011Severance, E.G., Dickerson, F.B., Viscidi, R.P., Bossis,
I., Stallings, C.R., Origoni, A.E., Sullens, A., Yolken, R.H., 2011. Coronavirus Immunoreactivity
in Individuals With a Recent Onset of Psychotic Symptoms. Schizophr Bull 37, 101–10"
\h Severance et al., 2011 ). Although, we cannot directly explain the role of SARS-CoV-2
in PP, we can propose possible mechanisms based on the available information in the
literature. It might be possible that altered immune mechanisms in patients with SARS-CoV-2
infection may be a risk factor for developing psychiatric illness. Neuropsychiatric
sequalae can also be due to a direct neurotoxic effect of the virus or the host’s
immune response towards it. Having comorbid COVID-19 infection or the fact that these
women had to deliver during the COVID-19 pandemic can itself put undue stress on them,
leading to precipitation of psychiatric illnesses, such as PP.
