Beyond the physical: Understanding the emotional and cognitive impact of MS

The major physical symptoms of multiple sclerosis are quite easy to recognise, and usually form the main focus of diagnosis and treatment. Muscle weakness, numbness, and coordination problems tend to stand out. They’re visible, measurable, and the effects are impossible to ignore.

But, MS affects far more than movement. 

Emotional and cognitive symptoms such as anxiety, depression, and issues with concentration and memory (referred to as MS brain fog) are the ‘secondary symptoms’ that rarely take centre stage, but they can (and often do) quietly shape many parts of life for people with multiple sclerosis. 

While there has been a shift in how MS is treated in the past decade or so, these less-than-obvious issues can take a bit of a back seat and sometimes go untreated for years. 

Yet for many, they’re up there with the most difficult parts of living with MS.

Today is World MS Day. A day to think deeply about how the condition is identified and then treated, and a timely reminder that the condition isn’t just physical. This year’s focus on visibility encourages a broader understanding of what life with MS truly involves, including the symptoms that don’t show up on a scan. 

For those living with these hidden challenges, recognition can be just as important as treatment.

Multiple sclerosis affects more than just the body

Symptoms that affect thinking, mood, feelings of self-worth, and memory/concentration can be difficult to predict or quantify, even for those experiencing them. They don’t follow predictable patterns, and they’re rarely consistent from one day to the next. 

That uncertainty can be disorienting. 

Tasks that were just part of everyday adult life can suddenly take far longer than expected, or feel impossible. People with MS describe difficulty finding the right words mid-conversation, losing track of their point, or forgetting what they were doing partway through a task. It’s not always obvious from the outside (a pause here, a repetition there), but the internal experience can be jarring. 

Some describe MS brain fog as mental lag, like the mind is half a beat behind where it should be.

These moments often come with a heavy sense of frustration or self-doubt. Even simple exchanges can start to feel draining and daunting, and can chip away at a person’s confidence in subtle ways. They affect how people engage with work, maintain relationships, or carry out basic routines. 

And when those around them don’t notice, or don’t understand, a sense of disconnection sometimes (and very understandably) grows.

What are the invisible symptoms of MS (brain fog)?

• Mood swings, anxiety, or low motivation - all of which can lead to depression creeping in. 
• Brain fog - difficulty concentrating, forgetfulness
• Trouble processing or organising information
• Symptoms that worsen with fatigue or stress
• A sense of mental distance or unreliability

World MS Day raises awareness of unseen symptoms

Today, the 30th of May, marks World MS Day. This year’s campaign, My MS Diagnosis, focuses on the delays many people face in getting a clear diagnosis. Early signs like brain fog, fatigue, and the mental health toll that an MS diagnosis brings are often missed or misread, especially when physical symptoms haven’t yet developed.

The theme Navigating MS Together points to something simple: that diagnosis is not just a medical process, but a personal one. By sharing patient stories, the campaign encourages better recognition of the condition in all its forms, not just the visible ones.

How common are emotional and cognitive symptoms in MS?

• Around 50% of people with MS experience anxiety and/or depression

• Anywhere between 40% to 70% report memory problems or poor concentration

The mental and emotional toll of MS is often underestimated

Cognitive symptoms don’t just affect the mind, they affect how people with MS move through the world and see themselves. When focus constantly drifts or memory routinely lapses, day-to-day quality of life and feeling of self-worth take a hit. 

So many mundane tasks start to require conscious energy, and it’s not easy to understand the toll that takes until even small tasks begin to feel overwhelming. Following a conversation, remembering an appointment, or finishing a thought can become unexpectedly tricky. Not all the time, but often enough to cause frustration, doubt, heavy annoyance - all of which slowly chip away at confidence. 

People often describe feeling less capable, less present, or slightly ‘not themselves’. It’s not just frustration, it’s a gradual loss of trust in their own processing skills.

A holistic approach to MS treatment: therapy, lifestyle tools, and (potentially) medical cannabis

Medical cannabis should not be seen (or advertised) as a straight replacement for conventional treatment options. But, for some people in the UK with MS, it is already making life much more manageable. 

When added as one part of a holistic MS treatment plan, medical cannabis may help lower feelings of depression and anxiety, reduce sleep disruptions, and help boost mental clarity when fatigue sets in.

This kind of support won’t suit everyone, and isn’t a ‘first line’ treatment option in the UK. For people with MS to be considered for a medical cannabis prescription, they need to have tried at least two conventional treatment options. 

But when prescribed carefully by a specialist doctor (with ongoing monitoring and support), cannabis-based treatment options can truly make a difference for some MS patients. 

Medical cannabis has also been shown to help with some of the physical symptoms of MS, including spasticity and pain. This physical symptomatic control can also support emotional well-being, making it easier to rest, to focus, or to move through the day with less pain and mental strain.

Still, cannabis is just one part of the MS treatment picture. 

What are the options for treating emotional and cognitive symptoms in MS?

Most patients with MS find that a combination of the available treatment options works better than a single treatment route. 

Pharmaceuticals can help (and are sometimes prescribed) when mental health concerns become a chronic issue. Antidepressants or antianxiety prescriptions are sometimes offered, depending on the individual and what they’ve already tried.

Talking therapies like CBT can offer space to work through emotional shifts and changes in self-image. Some people also find that structured routines and daily planning help reduce the mental strain of unpredictable symptoms.

Peer support plays a different role. It doesn’t offer a straight symptom control solution, but it can help with the sense of isolation that an MS diagnosis sometimes brings. Speaking with others with similar experiences often brings perspective and reassurance. Individual, at home methods can also make a big difference - mindfulness, self-compassion, and gratitude practices won’t fix everything, but they can help, especially on the harder days.

Can medical cannabis help treat the symptoms of MS?

In some cases, medical cannabis for MS should be considered as a potential addition to this wider plan. The two major cannabinoids produced by cannabis (CBD and THC) have both been shown to offer somewhat surprisingly impactful benefits for some people living with MS, particularly around pain, muscle spasms, sleep, anxiety, depression, and general emotional regulation.

That said, the results of cannabis-based treatment can and do vary, and not everyone responds in the same way. The dosage sizing, the type of medical cannabis prescribed, and the method of administration all play a part. So does the individual patient - their symptom profile, treatment history, and overall health.

Any decision to try medical cannabis should be made with support from a specialist who understands both the condition and all the treatments available. When it works, it’s often one part of a broader shift. Not a fix (as there is no cure for MS), but a small step towards feeling more stable and in control.

Here in the UK, service providers like MS-UK and the MS Society offer counselling, online groups, helplines, and resources that focus on the emotional and cognitive impact of MS, not just the physical.

What’s clear is that emotional and cognitive symptoms deserve the same level of attention and care as the physical ones.
