I agree that human brains co tinue to develop through the 20s.

In the UK CAMHS or CYPS (Child and adolescant mental health services or children and youn people services) have a hard cutoff at 18.

Someone who is 17 years 11 months old will be placed into a CYPS team and a CYPS in patient unit if needed, and someone who is 18 years and 1 day old will go to an adult team and adult inpatient units.

There are considerble problems at the moment with:

Transitioning from CYPS to adult services

Having enough inpatient beds for young people.

Young people either have to travel hundreds of miles to get a bed or they have to go into an adult unit. That's a serious breach of commissioning and regulators get involved.
