Attention deficit hyperactivity disorder (ADHD) is often associated with restless children who struggle to sit still, but in women, it can present more subtly, with difficulties concentrating, forgetfulness, poor organisation and managing emotions. These challenges can make everyday life exhausting, particularly when underlying symptoms go unrecognised.

Symptoms may also fluctuate with hormonal changes, including those that occur during the menstrual cycle and perimenopause. Researchers are exploring how hormones interact with brain chemistry and whether nutrition may help support brain health. Could hormonal fluctuations help explain why symptoms change at certain times of life, and can dietary choices make a difference?

Why ADHD Is Often Missed in Women

ADHD is a neurodevelopmental condition which affects attention, impulse control and in many people, activity levels. It begins in childhood but can continue throughout adulthood, although its presentation may change over time.

Research published in Neuroscience & Biobehavioral Reviews in April 2025 examined differences in ADHD symptoms between the sexes [4]. The systematic review included 13 studies and found that women were more likely to report certain inattentive symptoms, including mind-wandering, while men were more likely to display many hyperactive and impulsive symptoms. However, there was considerable overlap between the sexes.

These differences may help explain why ADHD is sometimes overlooked in women. Some develop coping strategies, such as relying on lists, over-preparing for tasks or spending considerable time trying to stay organised. Although these strategies can help manage everyday responsibilities, they may also make underlying difficulties less visible and contribute to delayed diagnosis.

ADHD can also overlap with anxiety, low mood and sleep difficulties, making it harder to identify what is driving particular symptoms. Recognising how ADHD can present in women is an important step towards appropriate assessment and support.

ADHD and the Menstrual Cycle: Do Hormones Affect Symptoms?

Many women with ADHD notice changes in concentration, motivation and emotional control around their period or during major hormonal changes. Research is beginning to explore why this happens.

A 2025 systematic review published in the Journal of Attention Disorders examined 11 studies on female hormones and ADHD [1]. The findings suggested that hormonal changes, particularly during puberty and throughout the menstrual cycle, may affect ADHD symptoms.

A 2023 Swedish study published in the Journal of Affective Disorders examined 773,047 women who gave birth between 2005 and 2013, including 3,515 who had been diagnosed with ADHD before pregnancy. Women with ADHD were around five times as likely to receive a diagnosis of postpartum depression and more than five times as likely to receive a diagnosis of postpartum anxiety disorders as women without ADHD. Among women with ADHD, 16.76% received a postpartum depression diagnosis and 24.92% an anxiety disorder diagnosis [6].

The researchers noted that more frequent contact with mental health services may have increased the likelihood of diagnosis. The findings highlight the importance of mental health support during the postpartum period, but do not establish that hormonal changes caused these outcomes

Hormonal changes throughout the menstrual cycle may also affect ADHD symptoms. During the days before a period, some women report greater distractibility, irritability and difficulty managing emotions. However, research is still limited, and studies have often involved small numbers of participants.

During perimenopause, fluctuating and declining oestrogen levels may coincide with sleep problems, forgetfulness and brain fog [2, 7]. These symptoms can overlap with ADHD, although they can also affect women without the condition. Perimenopause does not necessarily worsen ADHD in every woman, and more research is needed to understand how hormonal changes influence symptoms.

Oestrogen and Dopamine: How Are They Linked to ADHD?

One possible explanation involves the interaction between oestrogen and dopamine. Dopamine is a chemical messenger involved in attention, motivation, reward and other aspects of brain function. Oestrogen can influence dopamine signalling, providing a plausible explanation for why hormonal fluctuations might affect certain aspects of ADHD [2].

However, ADHD is not simply a dopamine deficiency. It involves complex differences in brain development and function. Researchers have not yet established exactly how changing hormone levels influence symptoms. The evidence is still developing, and larger studies are needed to clarify these relationships.

ADHD and Nutrition: What Does the Research Say?

ADHD has several contributing factors, including genetic influences and differences in brain development and function. Researchers are also investigating possible roles for the gut microbiome, inflammation and oxidative stress. Diet is of particular interest because it influences nutrient intake, digestive health and the environment in which gut bacteria live [3].

Some studies suggest that people with ADHD may have less healthy dietary patterns, while diets high in sugary drinks, sweets, refined carbohydrates and highly processed foods have sometimes been associated with more ADHD symptoms.

The relationship may work in both directions. ADHD-related difficulties, including impulsivity, irregular routines, sensory sensitivities and a preference for particular foods, can make it harder to plan meals or maintain a balanced diet.

Researchers are examining specific nutrients, including omega-3 fatty acids, vitamins and minerals, alongside broader dietary patterns such as the Western and Mediterranean diets. Studies have also explored supplements and dietary changes, although the strength of the evidence varies considerably.

ADHD and Cardiovascular Health: What We Know?

Researchers are investigating possible links between ADHD and cardiovascular health. A 2023 Dutch study of 300 women attending a specialist cardiology clinic found that 35% had a history of ADHD symptoms [5]. These women were younger than those without ADHD symptoms, but their overall cardiovascular profiles did not differ significantly.

Mediterranean Diet and ADHD: What Are the Potential Benefits?

Rich in vegetables, fruit, pulses, wholegrains, nuts, olive oil and fish, the Mediterranean diet provides fibre, healthy fats, vitamins, minerals and plant compounds called polyphenols.

Researchers are interested in whether eating these foods could influence processes associated with brain health, including inflammation and the gut microbiome. Some observational studies have linked healthier dietary patterns with fewer ADHD symptoms [3].

While the evidence is not yet strong enough to establish that the Mediterranean diet improves ADHD, nevertheless the eating pattern can be a practical way for women with ADHD to increase dietary variety and meet their nutritional needs.

ADHD, Fibre and the Gut–Brain Connection

Fibre is found in vegetables, fruit, beans, lentils, nuts and wholegrains. It supports digestive health and provides nourishment for certain beneficial gut bacteria. These bacteria can ferment some types of fibre to produce short-chain fatty acids, substances involved in maintaining the gut barrier and regulating immune function.

The gut–brain connection is another area of growing interest. The gut and brain communicate through several pathways, including the nervous system, immune signalling and substances produced by gut microbes. Studies have identified possible differences in the gut microbiome of people with ADHD. It is not yet clear whether these differences contribute to ADHD, result from dietary or lifestyle factors, or reflect a combination of influences.

Polyphenols are naturally occurring plant compounds found in foods like berries, apples, tea, cocoa and olive oil. Some may influence gut bacteria and biological processes associated with inflammation and oxidative stress.

Although these mechanisms are being investigated, much of the evidence linking the gut microbiome and polyphenols with ADHD remains preliminary [3].

Omega-3 and ADHD: What Does the Evidence Show?

Omega-3 fatty acids, particularly EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), are important for normal brain structure and function. Oily fish, such as salmon, sardines, mackerel and trout, provides EPA and DHA. Walnuts, chia seeds and flaxseeds supply another omega-3 fat, ALA (alpha-linolenic acid), which the body can convert into EPA and DHA, although conversion is limited.

Some studies suggest that children with ADHD consume fewer omega-3-rich foods and may have lower omega-3 levels than children without ADHD. However, research into omega-3 supplements has produced mixed results.

Some studies report modest improvements in attention or behaviour, while others find little benefit. It is possible that people with lower omega-3 levels at the beginning of a study respond differently from those who already have adequate intakes.

Vitamins and Minerals for ADHD: Can Deficiencies Matter?

Vitamins and minerals support many processes involved in brain function, including energy production, communication between nerve cells and the production of chemical messengers called neurotransmitters. Researchers have therefore investigated whether deficiencies in certain nutrients could contribute to ADHD symptoms.

Iron, zinc, magnesium and vitamin D have all been investigated in ADHD research. Some studies have identified associations between nutrient levels and ADHD symptoms, but findings are inconsistent and do not establish that supplementation benefits everyone with the condition.

Iron contributes to normal cognitive function and is involved in processes used to produce neurotransmitters, including dopamine. While zinc and magnesium support normal nervous system function. Vitamin D also plays important roles in general health. Correcting a confirmed deficiency is important, but taking additional nutrients when levels are already adequate has not been established as a reliable way to manage ADHD.

Practical Ways to Support Brain Health

Small, manageable changes may help women with ADHD maintain a balanced diet and look after their general wellbeing.

• Eat regular, balanced meals: Include protein, vegetables, fruit, wholegrains and healthy fats, choosing a variety of nutrient-rich foods.
• Include omega-3-rich foods: Oily fish, walnuts, chia seeds and flaxseeds are useful dietary sources of omega-3 fatty acids.
• Build up fibre gradually: Vegetables, fruit, pulses and wholegrains support digestive health and help nourish beneficial gut bacteria.
• Look for recurring patterns: Keeping a diary of symptoms, sleep and menstrual changes may help identify hormonal influences.
• Prioritise movement and sleep. Regular physical activity and consistent sleep routines support general health and wellbeing.
• Seek professional advice when needed: Persistent fatigue, heavy periods, restricted diets or worsening symptoms may warrant further assessment.

Frequently Asked Questions

Can hormones affect ADHD symptoms in women?

Hormonal changes during puberty and the menstrual cycle may be associated with changes in ADHD symptoms in some women. Research is still limited, particularly for perimenopause and menopause.

Can perimenopause make ADHD symptoms worse?

Some women report greater difficulties with concentration, memory or emotional regulation during perimenopause. These symptoms may overlap with menopause-related changes, but evidence that perimenopause consistently worsens ADHD remains limited.

Can diet improve ADHD symptoms?

A balanced diet supports general health and helps provide nutrients needed for normal brain function. Research into Mediterranean diet shows some promise, but more studies are needed.

Do omega-3 supplements help ADHD?

Some studies have reported modest benefits, but findings are inconsistent, and more research is needed.

Which vitamins and minerals are important for women with ADHD?

Iron, zinc, magnesium and vitamin D have all been investigated in ADHD research. They support normal bodily functions. Individual deficiencies should be assessed and addressed appropriately.

Bringing It All Together: Hormones, Nutrition and ADHD

Understanding ADHD in women means recognising that symptoms do not always remain the same throughout life. Hormonal changes may play a part, while good nutrition, regular routines and attention to overall wellbeing can provide a valuable foundation for general health. Although research is still developing, recognising individual patterns and seeking appropriate support can help women better understand their experiences and make informed choices about their health.
