These problems are permanent, though early treatment and support can help limit their impact on an affected child's life.
Speak to a GP or health visitor if you have any concerns about your child's development or think they could have foetal alcohol syndrome.
If the condition is not diagnosed early on and a child does not receive appropriate support, they're more likely to experience challenges associated with the condition.
A doctor or health visitor will need to know if your child was exposed to alcohol during pregnancy to make a diagnosis of foetal alcohol syndrome.
Your child may be referred to a specialist team for an assessment if there's a possibility they have the condition.
This usually involves a physical examination and blood tests to rule out genetic conditions that have similar symptoms to foetal alcohol syndrome.
There is no particular treatment for foetal alcohol syndrome, and the damage to the child's brain and organs cannot be reversed. But an early diagnosis and support can make a big difference.
Once the condition has been diagnosed, a team of healthcare professionals can assess the needs of the affected person and offer appropriate educational and behavioural strategies to meet these needs.
You may also find it helpful to contact a support group for people with foetal alcohol syndrome. These can be a good source of advice, and they may be able to connect you with other people in a similar situation.
There is a UK support group called NOFAS-UK. You might also want to ask your care team if they know of any local groups in your area.
Foetal alcohol syndrome is completely avoidable if you do not drink alcohol while you're pregnant.
The risk is higher the more you drink, although there's no proven "safe" level of alcohol in pregnancy. Not drinking at all is the safest approach.
If you're pregnant and struggling with an alcohol problem, talk to a midwife, doctor or pharmacist.
It's never too late to stop drinking: stopping at any point during pregnancy can help reduce the risk of problems in your baby.
