Cerebral palsy
Also called CP
A permanent difference in movement and posture, caused once, early. It does not get worse, and it is not an intellectual disability.

What it is
Two myths do most of the damage here, so deal with them first. Cerebral palsy is not progressive: the injury to the developing brain happened once, before or around birth, and it is not spreading. And it is not a learning disability. Roughly half of people with cerebral palsy have no intellectual impairment at all, and many of those who are assumed to have one simply cannot speak clearly.
What it does affect is movement, muscle tone and posture. Around 1 in 400 children in the UK are born with it.
The body changes even though the brain injury does not, because muscles that pull unevenly for thirty years reshape joints. That is why adult services matter, and why they are so thin.
Signs you might notice
Muscle tone that is too high (stiff) or too low (floppy), or that fluctuates.
Movements that will not do as they are told, especially fine ones.
Speech affected by the same muscle control problems, which is why intelligence gets misjudged so often.
Swallowing difficulties, which is dysphagia and carries a real risk of chest infection.
Pain. Around three quarters of adults with cerebral palsy report chronic pain, and almost nobody asks them about it.
How it can affect day-to-day life
The transition from children's services to adult ones is where things fall apart. Physiotherapy that ran weekly for eighteen years often stops entirely, and function that took a childhood to build is lost in a few years.
Fatigue is heavily underestimated. Walking with cerebral palsy costs several times the energy it costs anybody else, so a day that looks ordinary is not.
Then there is the assumption problem. People speak to the wheelchair pusher instead of the person, and use a slow, loud voice. Adults with cerebral palsy describe that as the single most wearing part of the condition.
Supporting someone well
Presume competence, every time, without needing evidence first. If speech is unclear, give it time and ask the person to repeat rather than turning to somebody else.
Keep movement going into adulthood. Push for physiotherapy after 18 and do not accept that it stops because the birthday did.
Ask about pain deliberately and regularly. It is present far more often than it is reported.
Position matters more than it sounds. Good seating and sleep positioning prevent hip and spine problems that later need surgery.
For unclear or absent speech, Fiducia Talk is free and includes switch scanning, which is what makes AAC reachable for somebody with limited hand control. Fiducia Guardian holds the therapy plans, the equipment, the medicines and the whole team in one record, which matters when a person has eleven professionals and no single view of them.
Where to get help
Push for a named adult neurology or rehabilitation contact before the move from children's services, not after.
Scope and Cerebral Palsy Cymru both provide practical guidance for adults, which is harder to find than the children's material.
Ask for a Care Act assessment at 18, and an Education, Health and Care plan review well before it.
