He hanged himself in the chambers at Christ Church Cathedral at Oxford.  Novelist William Styron on Depression fela wal you “In depression this faith in deliverance, in ultimate restoration, is absent. The pain is unrelenting, and what makes the condition hopeard intolerable is the foreknowledge that no remedy will come—not in a day, an hour, a month, or a minute.” “Soon evident are the slowed-down responses, near paralysis, psychic energy throttled back close to zero. Ultimately, the body is affected and feels sapped, drained.” “The pain of severe depression is quite unimaginable to those who have not suffered it, and it kills in many instances because its anguish can no longer be borne.”  The Soul-Searing Pain of Depression: “Hurt”* Music Video by Johnny Cash https://youtu.be/8AHCfZTRGiI *Song by Trent Reznor, Orig Performed by Nine Inch Nails  Clinical Features of Major Depressive Disorder (MDD) Cognitive: - sometimes,ele th -feeling ⚫ Pervasive sadness, tearfulness, excessive or inappropriate guilt, like they feelings of helplessness, emptiness, worthlessness. don't deserve ⚫ Recurrent thoughts of death (not just a fear of dying), suicidal forgiveness ideation, or a suicide attempt or plan. ↓ take steps to protect vs passive Motivational: person active one. passivethinkevena de ⚫ Pervasive anhedonia. > imagining I - , " Neurovegetative: don't feel any pleasure in anything a ⚫ Significant change in weight due to decreased or increased appetite lifing S (females tastegoodourished likelier to experience increased appetite). food doesn't keeption⚫ Sleep disturbance: insomnia or hypersomnia (females likelier to food only thing that makes them happy = func experience hypersomnia). sleep too much ⚫ Psychomotor agitation (“can’t sit still”) or retardation (inertia, leaden paralysis, “can’t get going”) (females likelier to experience overwhelmed retardation). how you move around people can get daily activities I shower ⚫ Pervasive fatigue or loss of energy. by ⚫ Difficulty thinking, concentrating, or making decisions. sometimes people mis-labeled dementia Not Due To: as ⚫ Bereavement, normal reaction to serious loss, or drug/medication effects. accutane linked to depression These signs and symptoms may result in social withdrawal and isolation, and in irritability (esp. in adolescents, and males across the lifespan).  Prevalence of Major Depressive Disorder (MDD) torsion (Pre-Covid) moderate ⚫ Point prevalence: about 5% of U.S. population are diagnosably depressed. ⚫ One-Year prevalence: about 7% in U.S., but varies widely across geographic regions. ⚫ Lifetime prevalence, 20.1% (26% of females, 12% of males), mostly moderate or severe depression.

If lithium were not available to me, or didn't work for me, the answer would be a simple no... and it would be an answer laced with terror. But lithium does work for me, and therefore I can afford to pose the question. Strangely enough, I think I would choose to have it. It's complicated... I honestly believe that as a result of it I have felt more things, more deeply; had more experiences, more intensely; loved more, and have been more loved; laughed more often for having cried more often; appreciated more the springs, for all the winters... Depressed, I have crawled on my hands and knees in order to get across a room and have done it for month after month. But normal or manic I have run faster, thought faster, and loved faster than most I know. - Kay Redfield Jamison - Touched with Fire (1993)  The Upside of Bipolar Disorder ⚫ The “well” relatives of people with Bipolar Disorder appear to have higher rates of achievement, success and creativity. ⚫ Thus, “the ‘dilute’ genotypes of the illness may have evolved to subserve adaptive functions such as exploration and risk taking. Such an evolutionary perspective represents the ultimate theoretical underpinnings of the concept of bipolar spectrum. The temperaments themselves, particularly the cyclothymic and hyperthymic, may further subserve such functions as interpersonal charm and sexual selection, and territoriality.” Akiskal, 2008  Suicide ⚫ Appropriate terminology: to “die by suicide”, not to “commit suicide.” (Crimes are committed.) ⚫ Suicide attempts should not be described as “failed” or “successful” but as “uncompleted” or “completed.” ⚫ Inappropriate to describe suicide attempts as “manipulative.”  Demographic Factors in Suicide ⚫ 30% increase in completed suicides over the past decade. Rates are increasing most in: – Military veterans. – Active members of military. – Youth belonging to sexual/gender minorities. ⚫ Increasing age: Rates are highest in middle-aged adults, second-highest is people >85 years old. ⚫ Being male: M:F rates run of completed suicides run 3:1 to 4:1, although the rates for females are now increasing faster than those for males. ⚫ Being Caucasian or American Indian. ⚫ Second-highest cause of death in adolescence, next to accidents. - CDC - CDC  Risk Factors in Suicide ⚫ The presence of mental disorder: – Mental Severe Major Depression or Bipolar depression is present in ¾ of people who attempt suicide. Co-morbid Alcohol Abuse or Dependence increases risk of an attempt. – Eating disorders (anorexia nervosa or bulimia nervosa) – Other predisposing disorders include Post-Traumatic Stress Disorder, Schizophrenia (with command hallucinations, especially). – Chronic pain disorder (usually itself co-morbid with Major Depression). ⚫ Personal history of previous attempts (but ~50% of people who attempt suicide complete on first attempt). ⚫ Family history of suicides or suicide attempts (may be associated with genetic abnormality: short allele of serotonin transporter gene). ⚫ Early history of sexual/emotional/physical abuse and/or neglect. ⚫ Current oppressive environment: harassment, bullying, shaming, unemployment, relationship rejection, divorce and loss of child custody. ⚫ Religious/philosophical/cultural values that consider suicide heroic (although many traditions consider suicide sinful). ⚫ Knowledge of recent deaths by suicide by friends, family, acquaintances, celebrities, etc. (suicide contagion). ⚫ Exposure to social media, especially for adolescents. ⚫ Ready availability of means of completion (drugs, prescribed meds, guns): the most common suicide in the U.S. is a Caucasian male in his 60’s who completes suicide by handgun.  Warning Signs of Suicidality ⚫ Talking about suicide, sometimes as a solution. ⚫ Withdrawing from normal activities, becoming secretive, increased drinking or drug use, failure to do schoolwork or go to work. ⚫ Not talking about the future, giving away important possessions or memorabilia. ⚫ Looking unhappy and making statements like, “what’s the point,” “I might just be better off dead,” “I’m no good to anybody anyway.” ⚫ Obtaining weapons, hoarding medicine instead of taking it as prescribed. ⚫ Making plans. (Ask person, “Have you thought about suicide?” “Have you thought how you would do it?” “Are you planning to take your life?”) Express concern and open a dialog about person’s thinking. ⚫ If friend or family is planning to die by suicide or “thinking about it,” ask person if he/she would be willing to get help. If yes, accompany person to nearest mental health center or ER. If not, phone police, nearest mental health center, or ER for guidance. Do so after telling person that you’re concerned for them and plan to seek guidance.  Prevention Strategies ⚫ Social level (may curtail personal freedoms): – reduce glamorization of suicide. – reduce chance of obtaining lethal means. – control harassing/bullying, or access to it, on social media. – construct barriers to suicide at “hotspots” like bridges and cliffs. – promote opportunities for “connection” for people who may be isolated. ⚫ Relationship level: couples or marital therapy for relationship/marital issues. ⚫ Personal level: promote awareness of mental-health signs and symptoms, and where treatment can be obtained. ⚫ Therapeutic level: – continual monitoring for suicidality in high - risk patients. – aggressive treatment of depression and issues of isolation, rejection, etc. – building of coping skills for handling crises. – formulation of “safety plan” with patient in case of crisis and imminent suicidality. Such a plan may include the number of a “hotline” or the local ER, or the admission # to the local psychiatric facility if there has been a prior admission. End
