Emotional and Cognitive Changes During Perimenopause
Have you felt more emotional, forgetful, or unlike yourself recently?
These changes are incredibly common during perimenopause.
If you're unsure whether this stage applies to you, start with our guide on what is perimenopause and the early signs.
What's Happening in the Brain?
Hormones influence:
- Mood
- Focus
- Stress response
Fluctuations can lead to anxiety, irritability, and brain fog. If anxiety is a key symptom for you, our article on anxiety in perimenopause explains this in more depth.
What You Might Notice
- Anxiety or low mood
- Irritability
- Brain fog
- Memory lapses
- Difficulty concentrating
Sleep disruption can also worsen these symptoms — learn more in perimenopause insomnia and 3am waking.
What Helps?
Understanding patterns is key. You can begin by using our perimenopause symptom checklist to track changes over time.
Key Takeaway
These changes are neurobiological, not a reflection of your capability.
Understanding this can reduce fear and self-blame.
