Brain fog and multiple sclerosis

We shine a light on this common MS symptom

Around 50 per cent of people with multiple sclerosis (MS) experience brain fog, and often it’s mild. But there’s no denying that issues with memory, attention and processing information can make things that bit harder day-to-day. Invisible to others, cognitive problems in MS are the result of nerve damage in the brain interrupting the transmission of electrical messages, reducing the speed and accuracy of the information.

Exercise

We know that exercise offers numerous benefits for people living with MS. One study in 2022 found that ‘moderate to vigorous’ activity was linked with improved mental processing speed in MSers.

Planning

While it won’t do much for the fog itself, scheduling challenging tasks for the times of day when you’re most alert can help you get more done. Perhaps you’re not a morning person? Then keep those things you mind mentally challenging until you’re fully alert.

If memory is an issue, take clear notes you can easily refer to. And many people report that avoiding multi-tasking and concentrating on doing one thing at a time without any distractions can ease the mental load.

An active brain

Cognitive reserve helps to buffer against cognitive difficulties MS can bring, but you can continue to build your reserve after an MS diagnosis. Education and new experiences help with this, so keep up hobbies, and do brain games, crosswords and puzzles.

Ask for help

Speak to your GP or MS nurse if you’ve begun to find cognitive issues are making things difficult. There are strategies you can try and you may be referred to a specialist who can help further.
