Serious mental illnesses, SMIs, such as schizophrenia, bipolar disorder, often first develop between the ages of 14 and 25. It's a critical stage for young people, because of the neurological, biological and cognitive changes of adolescence to young adulthood. It's a time of big change in their lives, reaching major educational milestones.

We often talk, don't we, about the need for early intervention to avoid mental health issues deteriorating. Plaid Cymru's long championed early intervention, including in more informal ways, or perhaps in less formal ways: the one-stop-shop drop-in centres, you'll have heard us promote, along the New Zealand model, and our amendment today refers to pilot schemes being introduced under the co-operation agreement, which I look forward to seeing develop, and they must develop. But these less formal interventions can affect clinical outcomes. Being aware of early signs of serious mental illness is a crucial first step in people getting the help they need, and clinical prevention is important. For many, it's the intervention of clinical teams that prevents further deterioration and illness. Early intervention and preventative strategies offer the opportunity to mitigate the stressors that impact on physical, emotional and psychological well-being at this really vulnerable time in a young person's life.

Psychosis affects one in 100 people. The first episode is most likely to happen between the ages of 18 and 24, but recent research says that fewer than one in five young people would be confident in spotting early signs—a quarter had never heard of it. So, Welsh Government has to meaningfully invest in specialist psychiatric medical provision in Wales, both now and in the long term.
