DSM-5 cultural and personality assessment of extreme overvalued beliefs
2021, Aggression and Violent BehaviorCitation Excerpt :Overvalued ideas are usually seen in clinical settings such as in anorexia nervosa, parasitophobia (e.g., Ekbom's syndrome or delusional parasitosis), body dysmorphic disorder, and hypochondriasis. These disorders have shared, intense beliefs associated with them which can develop into maladaptive behavior (Gelder et al., 1989; Oyebode, 2008; T. Rahman et al., 2013; T. Rahman et al., 2019; T. Rahman et al., 2020; Veale, 2002; G. Winokur, 1977). Indeed, such body image distortions have also been seen in members of the INCEL subculture, in which individuals share an ideology based on an inability to find a romantic sexual partner.
Short-term outcome of first episode delusional disorder in an early intervention population
2019, Schizophrenia ResearchCitation Excerpt :This study adds a unique insight into this debate by reporting on a cohort of first episode delusional disorder patients with a younger age of onset. Previous studies of delusional disorder reporting improved functional outcomes have suggested that delusional disorder has an older age of onset than schizophrenia (Kendler, 1982; Manschreck and Khan, 2006; Marneros et al., 2012; Winokur, 1977). This may not be directly comparable to the younger onset delusional disorder patients described here, who appear to present with a shorter DUP, better baseline functioning and fewer symptoms than patients with schizophrenia, and similar improvements over 12 months.
