Schizotypal personality disorder (SPD) is a severe mental disease that brings about serious difficulties and impairments in the lives of those affected by it. Those with SPD might be described as strange or unusual by other people. They are highly likely to have few intimate or close relationships. The purpose of this paper is to examine and discuss the etiology, individual and social impact, prognosis, and treatments for SPD. These details are important to study because SPD has been reported to be linked to violent behavior. A review of pertinent literature, mostly peer-reviewed journal articles, is carried out. The findings show that SPD has no known specific cause(s), results in severe physical, psychological, and social disabilities, and does not have any specific treatment. Further research on psychotherapeutic and pharmacological treatments is needed to improve prognosis for SPD, especially as regards its connection to violent behavior. Additional studies are also needed to conclusively identify SPD in all ages, which would help more effectively tailor psychotherapeutic and pharmacological interventions to the specific symptoms being presented.
