Suicide methodsA suicide method is any means by which a person may choose to end their lives. Suicide attempts do not always result in death, and a non-fatal suicide attempt can leave the person with serious physical injuries, long-term health problems, and brain damage. Worldwide, three suicide methods predominate with the pattern varying in different countries. These are hanging, poisoning by pesticides, and firearms. Some suicides are impulse decisions that may be preventable by removing the means.
Murder–suicideA murder–suicide is an act in which an individual kills one or more people either before or while killing themselves.
Self-harmSelf-harm is intentional behavior that is considered harmful to oneself. This is most commonly regarded as direct injury of one's own skin tissues usually without a suicidal intention. Other terms such as cutting, self-injury, and self-mutilation have been used for any self-harming behavior regardless of suicidal intent. The most common form of self-harm is using a sharp object to cut the skin. Other forms include scratching, hitting, or burning body parts.
HangingHanging is killing a person by suspending them from the neck with a noose or ligature. Hanging has been a common method of capital punishment since the Middle Ages, and is the primary execution method in numerous countries and regions. The first known account of execution by hanging is in Homer's Odyssey. Hanging is also a method of suicide. The past and past participle of hang in this sense is hanged rather than hung. There are numerous methods of hanging in execution which instigate death either by cervical fracture or by strangulation.
Social supportSocial support is the perception and actuality that one is cared for, has assistance available from other people, and most popularly, that one is part of a supportive social network. These supportive resources can be emotional (e.g., nurturance), informational (e.g., advice), or companionship (e.g., sense of belonging); tangible (e.g., financial assistance) or intangible (e.g., personal advice). Social support can be measured as the perception that one has assistance available, the actual received assistance, or the degree to which a person is integrated in a social network.
Mass suicideMass suicide is a form of suicide, occurring when a group of people simultaneously kill themselves. Mass suicide sometimes occurs in religious settings. In war, defeated groups may resort to mass suicide rather than being captured. Suicide pacts are a form of mass suicide that are sometimes planned or carried out by small groups of depressed or hopeless people. Mass suicides have been used as a form of political protest. Attitudes towards mass suicide change according to place and circumstance.
Suicide preventionSuicide prevention is a collection of efforts to reduce the risk of suicide. Suicide is often preventable, and the efforts to prevent it may occur at the individual, relationship, community, and society level. Suicide is a serious public health problem that can have long-lasting effects on individuals, families, and communities. Preventing suicide requires strategies at all levels of society. This includes prevention and protective strategies for individuals, families, and communities.
Obsessive–compulsive disorderObsessive–compulsive disorder (OCD) is a mental and behavioral disorder in which an individual has intrusive thoughts (an obsession) and feels the need to perform certain routines (compulsions) repeatedly to relieve the distress caused by the obsession, to the extent where it impairs general function. Obsessions are persistent unwanted thoughts, mental images, or urges that generate feelings of anxiety, disgust, or discomfort.
Solitary confinementSolitary confinement is a form of imprisonment in which an incarcerated person lives in a single cell with little or no contact with other people. It is a punitive tool used within the prison system to discipline or separate incarcerated individuals who are considered to be security risks to other incarcerated individuals or prison staff, as well as those who violate facility rules or are deemed disruptive. However, it is also used as protective custody on incarcerated individuals whose safety is threatened by others in order to separate them from the general prison population.
Suicidal ideationSuicidal ideation, or suicidal thoughts, is the thought process of having ideas, or ruminations about the possibility of ending one's own life. It is not a diagnosis but is a symptom of some mental disorders, use of certain psychoactive drugs, and can also occur in response to adverse life events without the presence of a mental disorder. On suicide risk scales, the range of suicidal ideation varies from fleeting thoughts to detailed planning. Passive suicidal ideation is thinking about not wanting to live or imagining being dead.
Post-traumatic stress disorderPost-traumatic stress disorder (PTSD) is a mental and behavioral disorder that develops from experiencing a traumatic event, such as sexual assault, warfare, traffic collisions, child abuse, domestic violence, or other threats on a person's life or well-being. Symptoms may include disturbing thoughts, feelings, or dreams related to the events, mental or physical distress to trauma-related cues, attempts to avoid trauma-related cues, alterations in the way a person thinks and feels, and an increase in the fight-or-flight response.
Adjustment disorderAdjustment disorder is a maladaptive response to a psychosocial stressor. It is classified as a mental disorder. The maladaptive response usually involves otherwise normal emotional and behavioral reactions that manifest more intensely than usual (considering contextual and cultural factors), causing marked distress, preoccupation with the stressor and its consequences, and functional impairment. Diagnosis of adjustment disorder is common. Lifetime prevalence estimates for adults range from five percent to 21%.
AnhedoniaAnhedonia is a diverse array of deficits in hedonic function, including reduced motivation or ability to experience pleasure. While earlier definitions emphasized the inability to experience pleasure, anhedonia is currently used by researchers to refer to reduced motivation, reduced anticipatory pleasure (wanting), reduced consummatory pleasure (liking), and deficits in reinforcement learning.
Mood disorderA mood disorder, also known as an affective disorder, is any of a group of conditions of mental and behavioral disorder where a disturbance in the person's mood is the main underlying feature. The classification is in the Diagnostic and Statistical Manual of Mental Disorders (DSM) and International Classification of Diseases (ICD).
Selective serotonin reuptake inhibitorSelective serotonin reuptake inhibitors (SSRIs) are a class of drugs that are typically used as antidepressants in the treatment of major depressive disorder, anxiety disorders, and other psychological conditions. SSRIs increase the extracellular level of the neurotransmitter serotonin by limiting its reabsorption (reuptake) into the presynaptic cell. They have varying degrees of selectivity for the other monoamine transporters, with pure SSRIs having strong affinity for the serotonin transporter and only weak affinity for the norepinephrine and dopamine transporters.
Social rejectionSocial rejection occurs when an individual is deliberately excluded from a social relationship or social interaction. The topic includes interpersonal rejection (or peer rejection), romantic rejection and familial estrangement. A person can be rejected or shunned by individuals or an entire group of people. Furthermore, rejection can be either active, by bullying, teasing, or ridiculing, or passive, by ignoring a person, or giving the "silent treatment".
Autism spectrumAutism, formally called autism spectrum disorder (ASD) or autism spectrum condition (ASC), is a neurodevelopmental disorder characterized by deficits in social communication and social interaction, and repetitive or restricted patterns of behaviors, interests, or activities, which can include hyper- and hyporeactivity to sensory input. Autism is a spectrum disorder, meaning that it can manifest very differently in each person. For example, some are nonspeaking, while others have proficient spoken language.
Hypothalamic–pituitary–adrenal axisThe hypothalamic–pituitary–adrenal axis (HPA axis or HTPA axis) is a complex set of direct influences and feedback interactions among three components: the hypothalamus (a part of the brain located below the thalamus), the pituitary gland (a pea-shaped structure located below the hypothalamus), and the adrenal (also called "suprarenal") glands (small, conical organs on top of the kidneys). These organs and their interactions constitute the HPA axis.
GriefGrief is the response to loss, particularly to the loss of someone or some living thing that has died, to which a bond or affection was formed. Although conventionally focused on the emotional response to loss, grief also has physical, cognitive, behavioral, social, cultural, spiritual and philosophical dimensions. While the terms are often used interchangeably, bereavement refers to the state of loss, while grief is the reaction to that loss.
Personality disorderPersonality disorders (PD) are a class of mental disorders characterized by enduring maladaptive patterns of behavior, cognition, and inner experience, exhibited across many contexts and deviating from those accepted by the individual's culture. These patterns develop early, are inflexible, and are associated with significant distress or disability. The definitions vary by source and remain a matter of controversy.
