Premenstrual Dysphoric Disorder (PMDD), Anxiety and ADHD

What exactly is PMDD?

Premenstrual Dysphoric Disorder (PMDD) affects up to 8% of women and goes far beyond typical symptoms associated with the premenstrual phase (often called PMS). While PMS might leave you feeling a bit moody or bloated, PMDD can feel like your mental health takes a nosedive for up to two weeks every month. That’s a substantial chunk of time.

The key difference between what you might call PMS and PMDD? PMDD symptoms are severe enough to significantly impact your relationships, work, and daily life. We’re talking about symptoms that can feel overwhelming and all-consuming, and happen every month. This is why its so important we talk about it, and find ways to manage the challenges and target all the associated symtpoms.

The anxiety connection

Many women with PMDD describe feeling like their anxiety gets “turned up to eleven” during the luteal phase (the two weeks before your period). This isn’t just coincidence – there’s real science behind it.

During this time, your progesterone levels rise and then drop dramatically. When progesterone breaks down, it produces a compound called allopregnanolone, which normally helps calm your nervous system. But in women with PMDD, this process seems to work differently, potentially making anxiety symptoms worse rather than better.

You might notice:

• Racing thoughts that feel impossible to quiet
• Physical symptoms like heart palpitations or sweating
• Feeling constantly on edge or irritable
• Difficulty sleeping or concentrating
• Overwhelming worry about things that don’t usually bother you
• That these symptoms happen suddenly but regularly for a portion of each cycle / month.

When depression joins the mix

Depression symptoms in PMDD can be particularly challenging because they can feel so intense, then seemingly disappear once your period arrives. The experience of these sudden changes in mood can be destabilising and make it difficult to plan work and life in general. It can also affect self-confidence and hope for the future. This rapid-changing pattern can also leave you questioning whether what you just experienced was “real” – and we want to be clear: this is absolutely a pattern that many women experience. It is real.

Common depression symptoms during PMDD include:

• Feeling hopeless or worthless suddenly
• Loss of interest in activities you usually enjoy
• Extreme fatigue or low energy
• Changes in appetite or sleep patterns
• Difficulty making decisions
• Thoughts of self-harm (if you’re having these thoughts, please reach out for support immediately)
• General lethargy and changes to alertness

The ADHD piece of the puzzle

Here’s where things get even more complex. Research suggests that women with ADHD might be more likely to experience severe premenstrual symptoms, including PMDD. This makes sense when you consider that both conditions involve similar brain areas and neurotransmitter systems, with likely implications for the HPA axis (a complex system of glands and hormones that regulates the body’s response to stress).

If you have ADHD, you might notice that your usual coping strategies stop working as well during the luteal phase (the 2 weeks leading up to your period). Tasks that are normally manageable might feel impossible. Your emotional regulation – already something that requires extra effort with ADHD – can feel completely out of reach. As can all those executive function systems like attention, focus, working memory, and planning.

Some women describe it as feeling like their ADHD medication stops working (which there is some evidence to suggest may be true), or like their brain fog becomes so thick they can barely function. This isn’t in your head – hormonal changes can actually affect how well ADHD medications work at different parts of your cycle each month.

Why this matters for your mental health

Understanding these connections is crucial because they help explain why you might feel like you’re struggling more than you need to be. When you’re dealing with multiple conditions that influence each other, it’s not just about adding symptoms together – it’s about how they interact and amplify each other. And the confusion of trying to sort out what is going on, and how to respond.

For example, if you’re someone who already manages anxiety, the hormonal changes of PMDD can make your usual coping strategies feel inadequate. Or if you have ADHD and rely on structure and routine, the mood changes of PMDD can make maintaining those routines feel impossible.

Finding your way forward

If you’re recognising yourself in this description, know that you’re not overreacting. These conditions are real, they’re interconnected, and most importantly, they’re treatable.

Keeping a symptom diary can be incredibly helpful – track your mood, anxiety levels, and any physical symptoms alongside your menstrual cycle. This can help you and your GP, psychologist, or healthcare provider identify patterns and develop strategies that work for your unique situation.

Treatment approaches might include:

• Therapy approaches that help with emotional regulation and coping strategies (e.g., CBT, ACT, Compassion Focused Therapy)
• Hormonal interventions 
• Antidepressants in some cases, particularly those that can be adjusted cyclically
• Lifestyle changes that support hormone balance
• ADHD coaching or therapy support that accounts for variation (look for a psychologist who has experience working with women with ADHD!)

How can a psychologist help?

Working with a psychologist who understands the complexity of PMDD can be transformative. We can help you develop targeted strategies that work with your unique pattern of symptoms rather than against them.

Cognitive Behavioural Therapy (CBT), Acceptance and Commitment Therapy (ACT), or Compassion Focused therapy (CFT)  have shown particular promise for PMDD. We might work together on developing coping strategies for those challenging two weeks, or explore how your thoughts and emotions about your symptoms might be adding to your distress. We help you to get back to your values and doing what matters most to you.

If you also have ADHD, we can help you adapt your existing strategies to account for hormonal fluctuations. This might mean developing different routines for different phases of your cycle, or creating backup plans for when your usual coping mechanisms feel less effective.

Therapy can also provide a safe space to process the frustration and grief that often comes with these conditions. Many women feel angry about losing two weeks of every month, or struggle with the unpredictability of their symptoms. These feelings are completely valid and working through them can be an important part of your healing journey.

We can also help you communicate with other healthcare providers, prepare for appointments, and advocate for the care you deserve. Sometimes having someone in your corner who understands these conditions can make all the difference in getting the support you need.

You don’t have to figure this out alone

Living with PMDD, especially when it intersects with anxiety, depression, or ADHD, can feel overwhelming. But understanding these connections is the first step toward finding relief.

Remember, seeking support is a sign of strength. Whether that’s talking to your GP, working with a psychologist who understands these conditions, or connecting with others who share similar experiences, you deserve support that acknowledges the full complexity of what you’re experiencing.

Your struggles are valid, your experiences matter, and there are people who understand. Most importantly, there are effective treatments available that can help you live well, even when your brain and body feel like they’re working against you.
