Multiple sclerosis and communication

Also called MS and speech, MS and dysarthria, MS and cognition

Speech, voice, word-finding and fatigue in MS: changes that come and go, and how to plan for the bad days without being defined by them.

What it is

Multiple sclerosis is a condition in which the immune system damages the coating of nerves in the brain and spinal cord, and the Health A-Z covers it as multiple sclerosis. Communication is affected for a large minority of people with MS, and unlike most of the conditions in this group, the difficulties often fluctuate: worse in a relapse, in heat, or at the end of a tiring day, better after rest.

The main threads are dysarthria (slurred, slow or scanning speech, where each syllable gets equal weight), voice changes, word-finding difficulties and slowed thinking, and the fatigue that makes all of them worse. Hearing and vision changes can come into it too.

Who it can help

People with any type of MS who've noticed their speech or their thinking-to-speaking has changed, their families, and employers who need to understand that a difficulty visible on Friday afternoon may be absent on Monday morning.

It isn't the guide for a steady decline; MS communication changes are mostly relapsing or slowly progressive, and planning is about managing variation rather than preparing for loss.

How it works

Damage to the cerebellum and brainstem gives the classic MS speech: slow, effortful, with a tremor in the voice and broken rhythm. Weak breath support makes it quiet. Fatigue is the amplifier, and cognitive fatigue in particular: the person's speech is clear but the words won't come and the thread is lost, which is a cognitive communication change rather than a speech one.

Therapy works on breath, pacing and clarity, and on strategies for the cognitive side: writing things down, one topic at a time, planning demanding conversations for good hours. Cooling helps some people, because heat worsens nerve conduction. A voice amplifier covers the quiet days.

For the rare person whose speech becomes very unclear, AAC follows the usual path, and the fluctuation argues for having a text-to-speech backup ready long before it's needed daily.

Getting started

Track it for a fortnight: when is speech or word-finding worst, and what came before (heat, a late night, a long meeting)? The pattern is the plan.

Ask the MS nurse for a speech and language therapy referral, and for a neuropsychology or occupational therapy assessment if the difficulty is thinking rather than speaking. At work, use Access to Work for an amplifier, speech-to-text software or a quieter space, and put the fluctuation in writing as a reasonable adjustment.

Put a text-to-speech app on your phone now and try it. Tell the people closest to you what helps on the bad days, so you don't have to explain when you least can.

Where to get help

The MS Society runs a helpline and local groups and has guidance on speech, cognition and fatigue. The MS nurse is the NHS coordinating contact, with speech and language therapy through the nurse, neurologist or GP; the RCSLT describes it. AbilityNet advises on technology adjustments at home and at work.
