A classification of combined homicide-suicide: An update-Part I: Introduction and psychopathology.

A 1995 classification of combined homicide-suicide was based on the psychopathology of the perpetrator and the relationship between the perpetrator and the victim(s). A three-part model was proposed for the study and potential understanding of individual homicide-suicide acts. This triarchic model consisted of the concepts of ego weakness, stress, and vector, the vector representing the ideational component. Today, approaching a quarter of a century after this initial classification based on a review of the literature available then, a considerable volume of experience and investigative knowledge has been published advancing our knowledge of homicide-suicide. The present review updates and revises the original classification, retains the two-part, psychopathological and relational classification, and adds several categories. Because this updated classification is more expansive than the original, it is presented in three parts. Part I, the present article, provides the introduction to this classification and the classification of mental conditions that may attend homicide-suicide. Parts II and III will address intrafamilial and extrafamilial homicide-suicide, respectively, the two major divisions of the classification based on the relationship between the actor and the homicide victim(s). All three parts are integral to this classification and belong together.

A classification of combined homicide-suicide: An update-Part II: Intrafamilial homicide-suicide.

This Part II of the three-part presentation of the updated classification of combined-homicide published in the Journal of Forensic Sciences addresses intrafamilial homicide-suicides (H-Ss). Intrafamilial H-Ss in this classification includes all close relationships including dating and intimate partners, not just traditional family relationships, in contrast to extrafamilial H-Ss where the victim(s) of homicide are either strangers or in a more formal but nonintimate relationship with the actor. Intrafamilial H-Ss are further divided and classified as intimate partner, filicide, familicide, parricide, and siblicide H-Ss, respectively, and are typically so grouped in the literature.

A classification of combined homicide-suicide: An update-Part III: Extrafamilial homicide-suicide.

The subclassification of homicide-suicide into psychopathology and intrafamilial homicide-suicides having been presented in the foregoing Parts I and II, this Part III concerns extrafamilial homicide-suicides. Extrafamilial homicide-suicides are divided into adversarial, autogenic mass, cult, and terrorist homicide-suicides. Adversarial homicide-suicides involve a "formal" relationship between actor and homicide victims, further divided according to the role of the actor in their relationship as employee, current or former pupil/student as in school shootings, patient, and litigant. For comparison, school shootings were divided into those resulting in 10 or more homicide victims and those with fewer. The autogenic mass homicide-suicide, wherein victims are strangers to the actor, was heuristically bifurcated here depending on the number of homicide victims, 10 or more or fewer. As expected, the homicide-suicides with larger numbers of victims were more homogenous.

Alcohol Use Disorder in Older Adults.

As the number of older adults worldwide continues to grow, we observe a proportional growth of substance use. Despite the myriad of complications alcohol use disorder (AUD) has on the body with regards to organ systems and mental health, the topic has been underresearched in the older adult population. Thus, it is important to create awareness about the growing problem of AUD among older adults. In this way, we can mitigate the long-term complications and side effects observed with alcohol abuse in this vulnerable population.

Bidirectional relationship between transient ischemic attacks and depression: A review.

BACKGROUND: An association between cerebrovascular events and psychiatric disorders has been reported. However, the focus has centered on stroke, and there has been a lack of attention to a possible relationship between transient ischemic attacks (TIAs) and depression. METHODS: We conducted a review of studies that looked specifically at the risk of depression after TIAs and the risk of TIAs in patients with depression. A total of 8 studies were identified, 4 examining the occurrence of depression following a TIA, and 4 examining the occurrence of TIAs after the onset of depression. RESULTS: There was a bidirectional effect: 3 of 4 studies showed an increased risk of TIAs in patients with depression, and 4 of 4 studies found an increase of depression following a TIA. The percentage of patients having a TIA from the pool of patients with depression was 3.18%. The percentage of patients who developed depression after a TIA in the pooled samples was 6.88%. CONCLUSIONS: Both depression and TIAs are serious medical disorders and they appear to have a bidirectional relationship. Further clinical and neurobiological studies in this area are warranted.
