mommy brain, mom brain, baby brain or even mamnesia. So many terms to describe the changes that take place in a new mother's brain after giving birth, in particular this state of memory loss.
Take care mama

mommy brain is a real thing, rest assured! Hormonal changes, as well as direct changes in the brain itself, are responsible for this state, and that is completely normal. 

What is mommy brain?

Postnatal depletion is the common phenomenon of tiredness and exhaustion, associated with a feeling of "baby brain".

The term "baby brain" encompasses symptoms of poor concentration, memory difficulties and emotional lability (emotions fluctuate far more easily than before — for example, crying for no reason [1]). Another term that exists is "brain fog", or "mental fog", which refers to a cluster of symptoms such as memory difficulties, an inability to concentrate, trouble processing information, fatigue and scattered thoughts.

A study showed that neurobehavioural performance deteriorates from the second week postpartum through to the end of the 12-week study period compared with the control group, despite improvements in postpartum sleep [2].

These observations can be partly explained by disruption to the sleep cycle in postpartum women, but given that this state persists, it can be assumed that other explanations exist for this phenomenon. Studies point to several explanations, including a hormonal impact, direct changes in the mother's brain, as well as the role of nutrition.

What changes occur in a mother's brain?

Many changes occur after giving birth. Some of them are partly responsible for mommy brain. 

Did you know?

DHA plays a very important role in the brain, particularly in memory. Furthermore, during your pregnancy and if you are breastfeeding, DHA contributes to the development of your baby's brain. 

Fluctuations in the hormonal environment of mothers during pregnancy may contribute to these brain changes. More specifically, variations in oestradiol, progesterone, prolactin, oxytocin and cortisol during pregnancy and the postpartum period have been implicated in brain plasticity [3]. 

A reduction in grey matter has also been observed, persisting for 2 years after delivery [3].
Studies on rodents have indicated that the expression of maternal behaviours is associated with structural changes in brain regions. Structural changes have been identified in brain regions in mothers during the first months of the postpartum period. Research has shown an increase in certain areas of the brain, notably the parietal lobe, which is linked to empathy, and the temporal lobe, which helps mothers to understand babies' cues [4].

What is the impact of DHA on mommy brain?

DHA is an omega-3 fatty acid essential for normal brain function. It is the primary omega-3 fatty acid found in the brain's grey matter (the site of mental processing and information storage), accounting for approximately 15% of all fatty acids [5].

The depletion of cerebral DHA is heightened by the physiological demands of pregnancy and lactation. Moreover, after one reproductive cycle, an 18% reduction in brain DHA levels has been observed [6]. After pregnancy, breastfeeding mothers have greater DHA deficiencies than those who do not breastfeed, yet neither group returns to normal DHA levels by 6 weeks postpartum [7]. Thus, even when taking the best breastfeeding food supplement, make sure you have good DHA intake, even if you are not breastfeeding. 

Furthermore, studies show that a suboptimal intake of DHA reduces DHA levels in the brain [8].

In animals, a low level of DHA in the brain leads to behavioural changes and is associated with learning difficulties and memory deficits [9]. In humans, studies suggest that DHA helps preserve learning and memory [10]. For example, one study showed that DHA supplementation could boost memory and reduce reaction time, which may be helpful for mommy brain [11].

Any alteration in the brain's fatty acid composition is likely to affect maternal neurobiology. This may be due to a reduction in DHA in the brain impairing serotonergic function [12]. Serotonin is notably involved in the regulation of behaviour, mood, anxiety, and learning [13].

Jolly Mama DHA

Omega Mama, our pregnancy omega-3, contains schizochytrium microalgae oil, which is naturally rich in DHA and vegan. One capsule provides 250 mg of DHA, to cover your needs and support your body before, during and after pregnancy.

Nore spread Crazy nut and our breastfeeding snack Cho-chocolat also contain this oil.

Baby Bump, our prenatal vitamin, also provides 200mg of DHA per day, derived from ultra-pure and stable fish oil.

Can other nutrients have an effect on mommy brain?

As Dr Oscar Serrallach explains, postnatal depletion is partly due to the fact that the placenta transfers many nutrients to the growing baby during pregnancy, drawing on maternal reserves (particularly for B vitamins and DHA)[14]. This transfer of nutrients may partly explain the mommy brain. 

For example, a study conducted with 202 people experiencing cognitive disorders and presenting low or deficient levels of vitamin B12 found that B12 supplementation led to an improvement in cognition in 84% of participants and an improvement in memory and attention test scores in 78% of participants [15]. Similarly, a recent study of 39,000 people found that low vitamin B12 levels were associated with attention and memory difficulties [16].
These findings have also been observed for vitamin B6 and folates [17].

Studies also show that stress can impair memory function[18]. It turns out that magnesium can help reduce stress levels[19], which may be beneficial for mommy brain. Furthermore, studies have highlighted a link between low magnesium status and impaired cognitive function[20].

How to overcome mommy brain?

Use lists and set reminders so you don't forget anything.

Sleep when you can. Your body is working hard and you need rest. After birth, sleep is disrupted and sleep deprivation can have cumulative effects, so rest whenever you can.

Don't hesitate to ask for help.

Try not to worry — do what you can to de-stress.

Be patient. Give your mind the space it needs to make these remarkable changes and adaptations. Know that you are not alone, and that these changes are proven to be normal.
