Parkinson's and communication

Also called Parkinson's disease and speech, Hypokinetic dysarthria, Hypophonia

Quiet, flat, fast speech and a face that no longer shows feeling: why people with Parkinson's get talked over, and the therapies with the strongest evidence.

What it is

Parkinson's is a progressive neurological condition, and the Health A-Z carries it as Parkinson's disease. This entry is about communication, which is affected for most people at some point: the voice gets quiet and breathy, the tone flattens, speech may speed up and words run together, and the face moves less, so expressions that used to carry meaning stop appearing.

The cruelty is that the person often doesn't hear it. Parkinson's alters the sense of how loud you're being, so the person feels they're speaking normally and is asked to repeat, or is simply talked over. And a flat face and voice get read as disinterest or low mood when the person is neither.

Who it can help

Anyone with Parkinson's, ideally from early on, because the voice therapy with the best evidence works better the earlier it starts. Partners and families, who can change how they listen. Care staff, who need to know the flat face isn't the person.

Some people with Parkinson's also develop word-finding or thinking changes later, which are covered under cognitive communication disorder and dementia; this entry is about the speech and voice.

How it works

The speech pattern is hypokinetic dysarthria: reduced movement in the muscles of breath, voice and articulation. Volume drops first (hypophonia), then pitch range, then clarity. Some people festinate in speech as in walking, accelerating and stumbling. Handwriting often shrinks the same way.

The therapy with the strongest evidence is loud voice training, best known as LSVT LOUD: an intensive course, typically four sessions a week for four weeks, that recalibrates the person's sense of loudness so that what feels like shouting is actually normal. Effects last months to years with practice. Pacing techniques and a pacing board help the fast talker. A personal voice amplifier helps in noisy rooms and on the phone.

Medication timing matters: speech is often best an hour after a dose and worst as it wears off. Plan conversations that matter for the good part of the cycle.

Getting started

Ask the Parkinson's nurse or GP for a speech and language therapy referral now, and ask whether LSVT LOUD or an equivalent intensive voice programme is available locally. Meanwhile, practise "think loud": read a paragraph aloud daily at a volume that feels too big.

As a listener, sit close, cut the background noise, and ask before you assume. "Are you enjoying this?" answers what the face can't. Give time; the response is coming.

For the phone, try Relay UK or a video call so the person can be seen. Keep a text-to-speech app on the phone for the wearing-off hours.

Where to get help

Parkinson's UK runs a helpline, local groups and detailed guidance on speech and communication. The Parkinson's nurse is the coordinating NHS contact, and speech and language therapy is via the nurse, neurologist or GP; the RCSLT explains the service. Age UK helps with the practicalities around it.
