Postpartum ADHD: When "Mom Brain" Might Be Something More

You're standing in the kitchen, the baby finally asleep after three attempts, and you have no idea why you walked in here. The to-do list you wrote this morning? Lost somewhere between the diaper bag and the car seat. You've reheated the same cup of coffee four times. Your partner asks if you called the pediatrician, and you genuinely cannot remember if that happened today or if you just thought about doing it.

"Mom brain," everyone says with a knowing smile. "It happens to all of us."

But here's what I want you to consider: What if it's not just "mom brain"? What if the scattered thoughts, the overwhelm, the feeling that your brain is running on 47 tabs with no ability to close any of them—what if that's something that was always there, and motherhood just turned up the volume?

The Hidden Connection: ADHD and the Postpartum Period

Research from the American Journal of Obstetrics & Gynecology confirms what many of my patients have discovered: ADHD symptoms frequently become more challenging to manage during the perinatal period. This isn't coincidental. The demands of new motherhood—sleep deprivation, constant task-switching, emotional regulation under pressure—hit the exact executive functions that ADHD affects.

Here's what the research tells us: A 2023 study published in the Journal of Clinical Psychiatry found that women with ADHD were five times more likely to be diagnosed with postpartum depression compared to women without ADHD. Five times. That's not a small difference—that's a signal that something important is being missed in how we support new mothers.

And it gets more specific. A 2025 Canadian study following over 2,500 couples found that mothers with ADHD symptoms had 70% higher odds of depression and 74% higher odds of anxiety in the 3-24 months postpartum compared to mothers without ADHD.

"Mom Brain" vs. ADHD: How to Tell the Difference

Before we go further, let me be clear: Some cognitive changes during the postpartum period are completely normal. Your brain is literally restructuring itself to help you respond to your baby. Research shows that pregnancy affects memory, concentration, and cognitive processing in most women.

But there's a difference between normal postpartum cognitive changes and ADHD that was undiagnosed before pregnancy or ADHD symptoms that have significantly worsened.

Normal Postpartum Cognitive Changes:

• Forgetting minor things (where you put your keys, what you came into a room for)
• Feeling mentally foggy, especially during sleep deprivation
• Difficulty concentrating when exhausted
• Taking longer to process information
• Symptoms that improve significantly with better sleep

Signs It Might Be ADHD:

• These patterns existed before pregnancy—they're just worse now
• Chronic difficulty with time management (always running late, underestimating how long things take)
• Emotional dysregulation that feels bigger than the situation warrants
• Hyperfocus on some tasks while being unable to start others
• A history of starting projects but not finishing them
• Symptoms that don't improve even when you get more sleep
• Feeling like you're working twice as hard as everyone else to keep up
• Chronic feelings of underachievement despite being smart and capable

Why ADHD Gets Diagnosed (or Worsens) During Motherhood

There's a reason so many women don't get diagnosed with ADHD until adulthood—and often until they become mothers. ADHD in women tends to present differently than in men. Instead of the hyperactive, climbing-the-walls presentation most people picture, women with ADHD often have the inattentive type: internal restlessness, difficulty with organization, emotional sensitivity, and a mind that won't stop racing.

Before kids, many women develop sophisticated coping mechanisms. You might have used extensive to-do lists, alarms, routines, and sheer willpower to keep things together. Graduate school? Difficult but manageable with enough caffeine and all-nighters. Career? Challenging but doable when you could hyperfocus.

Then you have a baby.

Suddenly:

• You can't control your schedule
• Sleep deprivation destroys your coping strategies
• You're constantly interrupted mid-task
• The executive function demands multiply exponentially
• Hormonal changes affect brain chemistry

As one of my patients described it: "It's like I was always juggling, but I'd gotten really good at it. Then someone handed me five more balls and took away my hands."

The Hormone Connection

Here's something that doesn't get talked about enough: Research suggests that individuals with ADHD may be more sensitive to hormonal fluctuations. This includes menstrual cycle changes, hormonal contraceptives, perimenopause—and the massive hormonal shifts of pregnancy and postpartum.

Estrogen has a significant impact on dopamine, the neurotransmitter most associated with ADHD. During pregnancy, estrogen levels soar. After birth, they plummet. For women with ADHD, this drop can feel catastrophic—not because you're weak, but because your brain is particularly sensitive to these shifts.

This is biology, not personal failure.

What You Can Do: Practical Next Steps

1. Look Back Before You Look Forward

Think about your life before pregnancy. Did you struggle with any of these?

• Difficulty finishing projects
• Chronic lateness or time blindness
• Losing things frequently
• Difficulty with boring or repetitive tasks
• Impulsive decisions (financial, relational, career)
• Difficulty sitting still or feeling internally restless
• Emotional reactions that felt bigger than the situation
• Needing pressure (deadlines, crises) to get things done

If you're nodding along, that's important information.

2. Talk to a Professional Who Understands Women and ADHD

This matters. ADHD presents differently in women, and not all providers are trained to recognize it. Look for someone who:

• Has specific experience with adult ADHD in women
• Understands how ADHD interacts with perinatal mental health
• Won't dismiss your concerns as "just mom brain"
• Can conduct a thorough assessment that looks at your whole history

3. Consider Environmental Supports While You Explore Diagnosis

Whether or not you pursue formal evaluation, these strategies can help:

• External organization systems: Visual schedules, phone alarms for everything, designated spots for commonly lost items
• Body doubling: Having someone nearby while you do tasks (even on a video call)
• Task batching: Grouping similar tasks together instead of constant switching
• Reducing decision fatigue: Meal planning, capsule wardrobes, automated bill pay
• Movement breaks: Physical activity helps regulate the ADHD brain

4. Address Sleep First

Sleep deprivation makes everything harder, but it especially impacts executive function. If you're not sleeping, it's nearly impossible to know what's "real" ADHD versus severe sleep deprivation mimicking ADHD symptoms. Getting help with night duties—even temporarily—can provide clarity.

Treatment Options If You Are Diagnosed

If you receive an ADHD diagnosis, there are multiple treatment approaches. A Danish study identified that about 23% of women continue ADHD medication throughout pregnancy and postpartum, while others adjust their approach.

For mild to moderate ADHD during the postpartum period, the American Journal of Obstetrics & Gynecology recommends psychoeducation, self-management strategies, coaching, and therapy as first-line interventions. Medication is also an option, and decisions about breastfeeding and stimulants should be made individually with your provider.

Research shows that women with ADHD who stop medication during pregnancy may experience higher levels of depressive symptoms and impaired family functioning. This doesn't mean you must take medication—it means the decision deserves careful, individualized consideration, not assumptions.

The Both/And of ADHD and Motherhood

Here's what I want you to hold:

You can have ADHD AND be a wonderful mother.
You can need support AND be strong.
You can struggle with executive function AND raise thriving children.
You can need accommodations AND be successful.

ADHD isn't a character flaw. It's a neurological difference that affects how your brain manages attention, time, and emotional regulation. In some contexts, it's actually an advantage—creativity, ability to hyperfocus on interesting tasks, thinking outside the box, responding well in crises.

The problem isn't you. The problem is that modern motherhood demands relentless executive function from everyone, and that's particularly hard for brains that are wired differently.

When to Seek Help

Reach out to a professional if:

• You're feeling overwhelmed most of the time, not just occasionally
• Your coping strategies aren't working anymore
• You recognize yourself in these descriptions and want answers
• You're experiencing symptoms of depression or anxiety alongside concentration difficulties
• Your functioning at home or work is significantly impaired

You deserve to understand your own brain. If "mom brain" doesn't explain what you're experiencing, that's worth exploring—not dismissing.

Because the answer might change everything.
