The short explanation
Brain fog, meaning forgetfulness, trouble concentrating and finding words, is common during perimenopause and menopause. It usually improves with time, but meanwhile there are ways to manage it at work. Practical strategies include writing things down, using phone reminders and calendars, breaking tasks into smaller steps, taking short breaks, and preparing notes before meetings. Doing the most demanding tasks at the time of day you feel sharpest can help.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Poor sleep from night sweats makes brain fog much worse, so treating sleep problems or flushes often improves concentration. Treatment options include hormonal and non-hormonal approaches.
- Stress, low mood, anxiety, thyroid problems, anaemia and low vitamin B12 can also affect memory and are worth checking.
- Some workplaces offer flexible hours or adjustments. Talking to a manager or HR, if you feel comfortable, may help.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell what is causing your brain fog or which treatment suits you. A doctor can check for other causes and discuss options.
