Williams Syndrome: What It Is and How to Support Teens and Adults
People with Williams syndrome are often the first to say hello, remember everyone's name and light up a room. But that friendly, chatty side can hide a lot of anxiety, and it can lead people to expect more than the person can manage day to day.
This guide explains Williams syndrome in plain language, what it can look like for teens and adults, what helps, how the NDIS fits in, and how we support people with Williams syndrome on the Gold Coast and Sunshine Coast.
What is Williams syndrome?
Williams syndrome is a genetic condition caused by a small missing piece of chromosome 7. It usually happens by chance and isn't caused by anything parents did, although a person with Williams syndrome has a 50% chance of passing it on to each of their children.
Estimates vary, but it affects somewhere between about 1 in 7,500 and 1 in 18,000 people. It's diagnosed with a specific genetic test, such as a chromosomal microarray, because a standard chromosome test can't pick it up.
What Williams syndrome can look like for teens and adults
A very social personality. Many people with Williams syndrome are warm, chatty and love being around people. They can also find it hard to read other people's intentions, and may be overly friendly with strangers.
Learning. Most people have a mild intellectual disability. Spoken language is often a real strength, while things like drawing, puzzles, maths and finding their way around are much harder. Because people talk so well, others often overestimate what they understand or can do on their own.
Anxiety. Anxiety is very common, affecting around 80% of people. Specific fears and phobias, worry about upcoming events and sensitivity to loud noises are all common.
Health. Heart and blood vessel problems, high blood pressure, high calcium levels, hearing loss and diabetes are more common in Williams syndrome. Regular health checks with a doctor who knows the condition are important.
Strengths. Many people with Williams syndrome have a great memory for people and conversations, a strong sense of empathy, and a real love of music.
What helps day to day
Routines and visual timetables, with plenty of warning before changes
Teaching words for feelings, and practising calming strategies like slow breathing when things are calm, so they're easier to use when anxiety hits
Everyone in the person's life responding to worries in the same calm, consistent way
Practising stranger safety in real places, such as saying no, walking away and telling a trusted person, and refreshing those skills often
Using music and favourite topics as motivation for learning new skills
Showing how to do something, rather than leaving the person to work it out by trial and error
Our post on the role of routine in reducing anxiety has more ideas that work well alongside these.
Williams syndrome and the NDIS
Williams syndrome is on the NDIS's List B, a list of conditions that are likely to result in a permanent impairment. That means the NDIS generally accepts it's lifelong, but you still need evidence of how it affects everyday life. Reports on intellectual disability, anxiety, safety in the community and the level of support needed day to day all help.
Depending on the person's plan and goals, NDIS funding may include core supports for daily living and community access, capacity building for independence and social skills, therapy such as psychology, occupational therapy and speech pathology, and support to find or keep a job.
How we support people with Williams syndrome
At Loving Life, we support teens and adults with Williams syndrome on the Gold Coast and Sunshine Coast. We build on their love of people while helping them stay safe, manage worries and do more for themselves.
1:1 support. Our 1:1 NDIS support gives the person a consistent worker who gets to know what worries them and what helps. That might be community outings, practising safety skills in real places, shopping, public transport, or building a routine that feels predictable.
Skill building. Through capacity building and daily living support, we work on practical independence skills, step by step and with lots of practice. If work is a goal, our Employment Assistance program can help.
Groups. Groups are often a highlight for people with Williams syndrome. A regular, well-supported group gives them a safe place to enjoy being social, make real friends and practise reading social situations.
Gold Coast (from The Hub in Nerang and out in the community): Skill Space, our weekday day program for life skills; Social & Skills for boys and young men; Girl Squad for girls and young women aged 17 to 25; and Cook. Learn. Thrive., our cooking program in the Hub kitchen.
Sunshine Coast (from The Studio, Moffat Beach and out in the community): ThunderBolts for young adults, Fun Friday, the Craft Group, Ladies Lunch and our Men's Group.
Our groups are small and well supported, and food on group days is on us, so no one misses out. You can see what each group does on our Gold Coast groups and Sunshine Coast groups pages.
Where to find more information
Genetic Alliance Australia can connect families with Williams syndrome support groups, and the Williams Syndrome Association has detailed information for families and adults. We also support people with intellectual disability, which often comes up alongside Williams syndrome.
