Brain fog is one of the most commonly reported bothersome symptoms during the perimenopausal transition.
While brain fog is not unique to peri-menopause, fluctuating hormones can make symptoms such as forgetfulness, difficulty concentrating, mental fatigue, and word-finding challenges feel much more noticeable.
It is a transitional symptom that often impacts confidence, work performance, and sense of self.
The good news is, it's not all in your head, the experience is real for many women and importantly, brain fog is not the same as cognitive decline.
There are several evidence-informed ways to support brain health during this stage of life:
〰️ Regular exercise to support BDNF (brain-derived neurotrophic factor), to protect neural connectivity.
〰️ Prioritising sleep, one of the biggest contributors to cognitive function.
〰️ Following a Mediterranean-style diet rich in vegetables, legumes, olive oil, nuts, seeds, herbs and oily seafood.
〰️ Ensuring adequate omega-3 intake through food or a quality supplement.
〰️ Minimising alcohol intake, which can worsen sleep, mood and cognitive symptoms.
〰️ Investigating potentially confounders such as iron deficiency, thyroid dysfunction, insulin resistance, and vitamin B12 deficiency.
If you're experiencing brain fog, know that you're not alone and that support is available. The team at Jean Hailes has some excellent patient resources for women wanting to learn more about navigating this transition .
