At risk mental state

At risk mental state, also referred to as clinical high risk (CHR) or ultra high risk (UHR), is the clinical presentation of those considered at risk of developing psychosis or schizophrenia. Such states were formerly considered as prodromal phases, during which individuals experience non-specific or attenuated symptoms of psychosis until the onset of an initial psychotic episode, but this view is no longer prevalent as a prodromal period cannot be confirmed unless the emergence of the condition has occurred.

The original specialist service for those with subclinical symptoms of psychosis was The Pace Clinic in Melbourne, Australia. Other clinics have since developed around the world.
