A useful place to begin when your brain and body both feel unfamiliar.
Perimenopause can affect sleep, mood, attention and memory. ADHD can affect those things too. That overlap can make it harder to know what deserves attention first. [1]
The terms
Perimenopause and menopause are related, but they are not the same thing.
Perimenopause is the transition leading up to menopause. Menopause is reached after twelve months without a period. The timing, symptoms and impact vary widely from person to person. [2]
The NHS has a clear overview of what may change, what support can look like and when to seek help. It is a strong place to start when you want information grounded in current UK health guidance.

Similar experiences do not always have the same explanation.
Forgetfulness, difficulty concentrating, poor sleep, irritability and feeling overwhelmed can all be part of an ADHD experience. They can also appear or change during perimenopause. Stress, health conditions, medication, life events and disrupted sleep may add their own layer. [1]
That is why this resource is designed for orientation rather than self-diagnosis. It can help you notice patterns and prepare questions, but it cannot tell you what is causing a particular symptom.
Preparing for a conversation
Bring the detail that matters to you.
It may help to note when changes began, what feels different, how sleep is affecting you and any patterns across your cycle. Share any new, severe or persistent symptoms with a qualified clinician.
