The oldest person who has been diagnosed with<unk>  was 29 years old at the time of his assessment in 2008. Most people with<unk>  are consistently low weight (3rd-25th percentile) and low stature due to a deficiency of growth hormone. Low mobility is often an issue. The cause of low mobility is thought to be neurological, therefore bone structure is not greatly affected. Seizures may or may not be present and can result in injuries for those who are more mobile. ADHD and bipolar disorder — which are sometimes present — can lead to dangerous behavior or outbursts. While most people with<unk>  show moderate intellectual disability, one case (age 14) has resulted in normal learning and social skills without intervention.
