Take care mama

Le mommy brain existe pour de vrai rassurez-vous ! Les modifications hormonales ou encore directement dans le cerveau sont responsables de cet état, et c’est 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?

Le DHA joue un rôle très important dans le cerveau, notamment la mémoire. Par ailleurs, pendant votre grossesse et si vous allaitez, le DHA contribue au développement du cerveau de votre bébé. 

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?

Le DHA est un acide gras oméga 3 essentiel au fonctionnement normal du cerveau. Il est le principal acide gras oméga 3 présent dans la matière grise du cerveau (lieu des opérations mentales et du stockage des informations), représentant environ 15% de tous les acides gras [5].

L'épuisement du DHA cérébral est accru par les exigences physiologiques de la grossesse et de la lactation. Par ailleurs, après un cycle de reproduction, on observe une diminution de 18% des niveaux de DHA dans le cerveau [6]. Après la grossesse, les mères qui allaitent vont avoir des carences plus importantes en DHA que celles qui n’allaitent pas, mais aucune des deux ne retrouve un niveau normal en DHA à 6 semaines après l’accouchement [7]. Ainsi, même en prenant le meilleur complément alimentaire allaitement, assurez-vous d'avoir de bons apports en DHA, et ce même si vous n'allaitez pas. 

De plus, les études montrent qu’un apport sous optimal en DHA diminue les niveaux de DHA dans le cerveau [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].

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.
