Why Does My ADHD Feel Worse? Understanding the Connection to ADHD, Perimenopause and Brain Fog
Written by Jessica Walsh, Board-Certified Psychiatric Mental Heath Nurse Practitioner
ADHD is a neurodevelopmental condition that affects attention, organization, memory, and emotional regulation, and during perimenopause those symptoms may feel worse or more disruptive. Perimenopause symptoms often begin in the mid-40s and usually last about four years, but for some women with ADHD, perimenopause symptoms start earlier, with changes in focus, mood, sleep, and mental health increasingly difficult to manage.
2025 research published in European Psychiatry tracked women with and without ADHD, and found women with neurodivergent traits more often experience severe mood disruption during perimenopause than women without ADHD with mood-related perimenopause symptoms that can begin up to 10 years earlier than expected. The data concluded that peak mood disruption for women with ADHD occurs from ages 35 to 39, with women often experiencing a significant worsening of ADHD symptoms and cognitive impariment happening most frequently between ages 35 and 44 (Jakobsdóttir Smári et al., 2025).
This often overlooked neuropsychiatric overlap matters for women’s mental health. Hormonal changes involving estrogen and progesterone intensify challenges for ADHD women that already affect daily life. In my practice, I see many women seeking psychiatric treatment reporting difficulty sleeping, paralyzing brain fog, unpredictable mood swings, irritability, rage, or worsening anxiety causing a significant disruption in work, relationships, mental health, and routines.
During my late 30’s and early 40’s, I experienced mood swings, impulsivity, reactivity, and rejection sensitivity resulting in many personal relationship disruptions. The hormonal shift is brutal, and it unmasks vulnerabilities women with ADHD didn’t even know they had.
As a psychiatric provider, the lived experience between ADHD, perimenopause, and brain fog is deeply personal. But what does this connection actually mean? And how can women tell the difference between ADHD symptoms and changes related to perimenopause?
The Connection Between ADHD and Perimenopause
ADHD, or attention deficit hyperactivity disorder, and perimenopause may intersect in ways that affect how women think, feel, and function in everyday life.
During perimenopause, hormonal fluctuations, particularly changes in estrogen, can affect sleep, mood, cognition, and overall well-being. For women who already have ADHD, these changes may make existing difficulties with attention, organization, memory, or emotional regulation more noticeable. If you have diagnosed ADHD you might notice that your stimulant medication is not effective during certain times of the month, most notably your luteal phase.
This does not mean that perimenopause causes ADHD. ADHD is a neurodevelopmental condition characterized by persistent patterns of inattention, hyperactivity, and impulsivity that begin before age 12, although many women are not diagnosed until adulthood. ADHD can present as predominantly inattentive, predominantly hyperactive-impulsive, or combined; examples include difficulty maintaining focus or losing essential items, and constant fidgeting or interrupting others. Instead, the hormonal changes of perimenopause cause previously manageable symptoms to become unmanagable.
Perimenopausal Symptoms in Women With ADHD
Research suggests that women with ADHD may report a greater overall burden of perimenopausal symptoms than women without ADHD.
These symptoms can extend beyond changes in the menstrual cycle. They may include somatic (physical), psychiatric, and/or urogenital (genitourinary) symptoms.
Some women may experience:
● Brain fog
● Fatigue and changes in energy
● Sleep difficulties
● Mood changes or irritability
● Anxiety
● Difficulty concentrating
● Memory problems
● Other physical symptoms
● Urogenital or genitourinary symptoms
For a woman already managing ADHD, experiencing several of these changes at the same time can make everyday responsibilities feel more difficult. Work, household tasks, relationships, and other responsibilities may require more effort than they did previously.
Why ADHD Symptoms May Become More Noticeable During Perimenopause
One possible reason for this overlap involves the relationship between hormonal changes and brain function. Estrogen interacts with neurotransmitter systems involved in cognition and mood, including dopamine pathways relevant to ADHD. Researchers believe that fluctuations in estrogen during the menopause transition may contribute to changes in attention, mood, and executive functioning, although more research is needed to fully understand this relationship.
As hormone levels fluctuate during perimenopause, some women may notice changes in concentration, motivation, memory, emotional regulation, and sleep.
Consider someone who has always needed reminders to stay organized or has developed strategies to manage distractibility. If sleep becomes disrupted and concentration becomes more difficult during perimenopause, those strategies may no longer feel as effective.
The result can be a feeling of, “Why does everything suddenly seem harder?”
It may not be that the person has suddenly developed ADHD. Instead, existing ADHD symptoms may become more noticeable while perimenopausal changes add another layer of difficulty.
Understanding the Overlap Between ADHD and Perimenopause
ADHD and perimenopause share several symptoms, which can make it challenging to determine what is contributing to changes in functioning.
Both may involve:
● Difficulty concentrating
● Forgetfulness or memory problems
● Sleep difficulties
● Irritability or mood changes
● Feeling overwhelmed
● Difficulty organizing or completing tasks
● Changes in energy and motivation
Looking at the timing and history of symptoms can be particularly important. ADHD symptoms generally reflect a lifelong pattern, even when they were not recognized or diagnosed until adulthood. Perimenopausal symptoms, in contrast, develop during the hormonal transition leading up to menopause.
For some women, the answer may not be one or the other. ADHD and perimenopause can occur together, and both may contribute to changes in daily functioning.
Getting Support During Perimenopause
Significant changes in concentration, memory, mood, sleep, or daily functioning should not simply be dismissed as “getting older.”
Women experiencing these changes can benefit from discussing their symptoms and history with a qualified healthcare professional. Diagnosis involves clinical history, symptom questionnaires, and information about functioning across settings. You may be asked to keep track of menstrual patterns changes, sleep, mood, concentration, energy, and physical symptoms to provide useful information.
A comprehensive psychiatric assessment can help determine whether your symptoms are related to ADHD, perimenopause, another psychiatric concern, or a combination of factors. Treatment options may include medication management, stimulants, non-stimulant medications, behavioral therapy, or a combined approach. Treatment and support should be individualized based on a person’s symptoms, medical history, and overall health. IN Focus First Psychiatry offers a 60 minute to 120 minute comprehensive psychiatric evaluation with transparent pricing starting at $425.
It is also important to remember that every woman’s experience is different. Age, lifestyle, stress, sleep, overall health, and social circumstances can influence how someone experiences perimenopause.
Although awareness of the connection between ADHD and perimenopause is growing, research specifically examining women with ADHD remains marginalized. More research is needed to better understand how hormonal changes during perimenopause affect ADHD symptoms and the overall well-being of women during this time.
Most importantly, IN Focus First identifies women should no longer be told by healthcare simply “push through” significant changes in how they think, feel, or function. Recognizing the possible connection between ADHD and perimenopause can be an important first step toward receiving appropriate evaluation, treatment, and support.

The way hormonal changes can amplify difficulties with focus, memory, sleep, mood, and emotional regulation deserves much more attention. I particularly appreciate how this highlights that symptoms appearing or worsening during this stage may not simply be dismissed as stress or “normal aging.” Greater awareness could help women recognize what they are experiencing and seek appropriate support sooner. The overlap between neurological and hormonal changes is complex, but conversations like this can help reduce confusion and encourage more informed, compassionate approaches to women’s mental health.
