Dopaminergic neurotransmission plays a crucial role in the genesis and maintenance of alcohol dependence. Epigenetic regulation via promoter specific DNA methylation of the dopamine transporter gene (DAT) may influence altered dopaminergic neurotransmission in alcoholism. Aim of the present study was to investigate DNA promoter methylation of DAT in early alcohol withdrawal and in relation to alcohol craving. We analyzed blood samples of 76 patients admitted for detoxification treatment and compared them to 35 healthy controls.
Erotomania is the delusional belief that one is passionately loved by another. These persons often go to great lengths to approach their object of desire, often necessitating the attention of the law. We have reviewed a forensic sample to select subjects who meet criteria for the diagnosis of erotomania. Case histories from all of the case files of the Threat Management Unit of the Los Angeles Police Department were reviewed to compare erotomanic subjects with those who were suffering from other disorders.

OBJECTIVE: This paper is the first of a 2-part review on the topic of stalking. It outlines the behaviours involved, epidemiology, motivation of offenders, and mental health consequences for the victim. METHOD: Computerized literature searches were used to identify relevant papers from psychiatric and legal journals. Publications by victims' and women's organizations provided additional information. RESULTS: Up to 1 in 20 women will be stalked during her lifetime. The majority of victims are female, while the offenders are usually male.
Stalking, which has been given the clinical term "obsessional following", is repetitive threatening or harassing behavior that creates a fear of harm in the victim. Empirical and theoretical literature on this form of behavior is beginning to develop and focuses primarily on adults. Three major subtypes of obsessional following have been identified: erotomania, love obsessional, and simple obsessional/borderline erotomania. Using this typology and available empirical research, a context is set in which three cases of adolescent obsessional following are discussed and analysed.
This study investigated the prevalence and predictors of unwanted pursuit behaviors among college students. Participants (n = 282) had experienced the termination of a meaningful romantic relationship. Two questionnaires were administered. One assessed unwanted pursuit behaviors that were perpetrated by individuals who had not initiated the relationship breakup (breakup sufferers; n = 120); the other assessed individuals who had initiated the relationship breakup (relationship dissolvers; n = 162).
Two studies of the correlates of self-reported courtship persistence, stalking-like behaviors following a relationship break-up, and psychological maltreatment of partners were conducted in samples of male (N = 46 and 93) and female (N = 123 and 110) college students. Approximately 40% (38.5% and 44.6%) engaged in at least one stalking behavior following a break-up. A total of 10.7% (study 1) and 7.6% (study 2) engaged in 6 or more stalking behaviors. Stalking was significantly related to psychological maltreatment of the partner (PMP) prior to the break-up.
This study investigated female experiences of stalking by former partners following the dissolution of heterosexual romantic relationships. It aimed to identify those characteristics of former partners that were associated with stalking as opposed to other post-relationship experiences of minor harassment or no-harassment. Three hundred and five female undergraduates (all had experienced dissolution of a heterosexual romantic relationship) completed a 48-item questionnaire.
Passion is defined as a strong inclination toward an activity that people like, that they find important, and in which they invest time and energy. Two types of passion are proposed: obsessive and harmonious. Obsessive passion (OP) refers to a controlled internalization of an activity in one's identity that creates an internal pressure to engage in the activity that the person likes. Harmonious passion (HP) refers to an autonomous internalization that leads individuals to choose to engage in the activity that they like.
Obsessive love and delusional jealousy as persistent mental disorders, are well-known but rare psychiatric conditions, the prevalence of which is estimated to be less than 0.1%. Delusional jealousy should not be confused with exaggerated "pathological" jealousy, which is characterized by excessive suspicion and possessiveness on the part of individuals who, as a rule, suffer from considerably disordered self-esteem. As a paranoid development, delusional jealousy occurs in particular among male chronic alcoholics.
We examine the nature and predictors of social and romantic functioning in adolescents and adults with ASD. Parental reports were obtained for 25 ASD adolescents and adults (13-36 years), and 38 typical adolescents and adults (13-30 years). The ASD group relied less upon peers and friends for social (OR = 52.16, p < .01) and romantic learning (OR = 38.25, p < .01).
