Although psychotic disorders such as schizophrenia usually present in late adolescence or early adulthood, research suggests that a substantial subset of people are diagnosed for the first time after the age of 60. This condition is referred to as 'very late-onset schizophrenia-like psychosis' (VLOSLP). People with VLOSLP are thought to experience high levels of social isolation, yet there has been little research systematically examining this. Additionally, little is known about how lonely people with VLOSLP feel, or how this group relate to and perceive other people.
