Developmental co-ordination disorder (DCD), also known as dyspraxia, is a condition affecting physical co-ordination that causes a child to perform less well than expected in daily activities for his or her age, and appear to move clumsily.
DCD is thought to be around three or four times more common in boys than girls, and the condition sometimes runs in families.
This topic is about DCD in children, although the condition often causes continued problems into adulthood.

Symptoms of DCD
Early developmental milestones of crawling, walking, self-feeding and dressing may be delayed in young children with DCD, and drawing, writing and performance in sports are usually behind what is expected for their age.
Although signs of the condition are present from an early age, children vary widely in their rate of development, and DCD isn't usually definitely diagnosed until a child with the condition is around five years old or more.

When to seek medical advice
Talk to your GP or health visitor – or a nurse, doctor or special educational needs co-ordinator (SENCO) at your child's school – if you have any concerns about your child's health or development.
If necessary, they can refer your child to a community paediatrician, who will assess them and try to identify any developmental problems.

Causes of DCD
Carrying out co-ordinated movements is a complex process that involves many different nerves and parts of the brain.
Any problem in this process could potentially lead to difficulties with movement and co-ordination.
It's not usually clear why co-ordination doesn't develop as well as other abilities in children with DCD.
However, a number of risk factors that can increase a child's likelihood of developing DCD have been identified.
- being born prematurely – before the 37th week of pregnancy
- being born with a low birth weight
- having a family history of DCD – although it is not clear exactly which genes may be involved in the condition
- the mother drinking alcohol or taking illegal drugs while pregnant
There's no cure for DCD, but a number of therapies can make it easier for children to manage their problems.
- being taught ways of carrying out activities they find difficult – such as breaking down difficult movements into much smaller parts and practising them regularly
- adapting tasks to make them easier – such as using special grips on pens and pencils so they are easier to hold
Although DCD doesn't affect how intelligent a child is, it can make it more difficult for them to learn and they may need extra help to keep up at school.
Treatment for DCD will be tailored to your child and usually involves a number of different healthcare professionals working together.
Although the physical co-ordination of a child with DCD will remain below average, this often becomes less of a problem as they get older.
However, difficulties in school – particularly producing written work – can become much more prominent and require extra help from parents and teachers.
