Introduction to the special issue: How nonclinical psychology research can inform clinical perspectives on disgust.

Disgust is a universal emotion that significantly impacts human behavior and psychological well-being. While clinical psychology researchers made great strides in understanding disgust in the context of psychopathology, nonclinical researchers have contributed valuable insights that can inform clinical perspectives on disgust. This special issue aims to bring together the latest nonclinical research that can shed light on the nature, causes, and consequences of disgust-related psychopathology. The five articles in this issue cover various nonclinical topics, including inhibitory learning, autobiographical memories, food preferences, and the perception of self and others. This issue also covers the role of disgust in specific clinical disorders, including anxiety disorders, obsessive-compulsive disorder, posttraumatic stress disorder, eating disorders, neurodegenerative disorders, and more. By showcasing novel approaches to researching clinical aspects of disgust, this special issue provides a comprehensive and up-to-date understanding of the complex phenomenon of disgust and future directions in research.

Exploring the role of the self in disgust-related psychopathologies.

While clinical research on disgust relies on nonclinical research, the framework of disgust as an immune mechanism is not as central in clinical research. The immune framework for disgust may be integrated into clinical research by acknowledging the role of the self as the critical element protected by the immune system. In this review, we offer the premise that at the center of all disgust-related behaviors, thoughts, and cognitions is an attempt to protect the self (i.e., "disgust is self-centered" or DISC). We offer evidence in support of DISC and explore the relevance of DISC to clinical research for several disgust-related psychopathologies (obsessive-compulsive disorder, posttraumatic stress disorder, anorexia nervosa, and self-disgust). We then offer future directions for DISC research into disgust-related psychopathologies.

Safety and Efficacy of Medical Cannabis Oil for Behavioral and Psychological Symptoms of Dementia: An-Open Label, Add-On, Pilot Study.

BACKGROUND: Tetrahydrocannabinol (THC) is a potential treatment for Alzheimer's disease (AD). OBJECTIVE: To measure efficacy and safety of medical cannabis oil (MCO) containing THC as an add-on to pharmacotherapy, in relieving behavioral and psychological symptoms of dementia (BPSD). METHODS: Eleven AD patients were recruited to an open label, 4 weeks, prospective trial. RESULTS: Ten patients completed the trial. Significant reduction in CGI severity score (6.5 to 5.7; p <  0.01) and NPI score were recorded (44.4 to 12.8; p <  0.01). NPI domains of significant decrease were: Delusions, agitation/aggression, irritability, apathy, sleep and caregiver distress. CONCLUSION: Adding MCO to AD patients' pharmacotherapy is safe and a promising treatment option.

Psychosocial and medical aspects of older suicide completers in Israel: a 10-year survey.

OBJECTIVES: The rate of completed suicide among the elderly continues to be the highest of any age group worldwide. The aim of the present study was to investigate the sociodemographic data, mental and physical health characteristics, and suicide methods of the elderly population who completed suicide in Israel. METHODS: A national retrospective record-based case series study of consecutive elder (50 years or older) suicide completers who had undergone autopsy over a 10-year period was conducted. RESULTS: Three hundred and fourteen consecutive records of suicide completers, 69.6% males, and mean age 64.7 were analyzed. The largest group (38%) emigrated from the Former Soviet Union and 19% emigrated from East Europe. Immigrants from East Europe committed suicide at an older age. Hanging was the predominant suicide method. Jumping from height increased more than threefold in the 'old-old'(older than 75 years) group. Hanging and firearms were more frequently used by males. Females were more likely to employ poisoning and suffocation. A significant minority (30%) had been diagnosed as suffering from psychiatric morbidity. Most common diagnoses were depression and alcohol abuse or dependence. Physical disorders (mainly cardiovascular disease and malignancy) were present in 27% of cases. Subjects with psychiatric illness were more likely to complete suicide at a younger age compared with subjects with physical illness. CONCLUSIONS: Findings of male predominance, psychiatric morbidity, and physical illness are consistent with previously published studies. Immigrants from East Europe completed suicide at an older age and the older victims had used more lethal methods of suicide.
