Transcript of IzBen C. Williams, MD, MPH Lecturer. The Lifecycle III AGEING, DEATH and BEREAVEMENT

  • Slide 1
  • IzBen C. Williams, MD, MPH Lecturer
  • Slide 2
  • Slide 3
  • WHO or WHAT IS OLD In contemporary urban societies, chronological boundaries for life phases (youth, middle age, and old age) are continuously being revised upwards as medical and social advances extend the vitality and productivity of older adults
  • Slide 4
  • Slide 5
  • Truth is that aging proceeds at different rates in different individuals and at different rates with specific organ systems of an individual. Many persons seem old in body or spirit at age 50 and others scarcely so at age 65 or 70
  • Slide 6
  • Whence 65+ The common practice of designating people over age 65 as old began in Germany in the 1880s when Otto von Bismarck selected 65 as the starting age for certain social welfare benefits The question is: Should this continue to be the qualifying standard?"............ Gerontologists as well as politicians continue to struggle with this question
  • Slide 7
  • Life Expectancy USA 150 years
  • Slide 8
  • Life expectancy USA 100 yrs
  • Slide 9
  • Aging Epidemiology The 65+ population now comprises about 12% of the US population Projections suggest that by 2020 more than 15% of the US population would be more than 65 years old In the USA the fastest growing segment of the population is over age 85 By 2050, 5% of the population would be over 85 Contrast this with US census 1900
  • Slide 10
  • Age Just a number To avoid undue emphasis on chronological age, it may be useful to think of each person as having several different ages, eg: biological, psychological and social And to recognize that individuals may be aged in one continuum and youthful in another
  • Slide 11
  • Biology of Aging -1 Aging is not a disease, though often it is accompanied by dis-ease But irreversible changes including some disease changes often accompany aging Distinguishing between changes due to normal aging and those due to disease processes is not always straightforward
  • Slide 12
  • Biology of Aging -2 Distinguishing between normal senescence and senility (by way of example): Senescence involves slowing, varying from scarcely noticeable to moderate changes. Relationships not impaired Senility is a serious illness with progressive cognitive compromise and often death within a few years (incidence 10% over 65; 20% over 85)
  • Slide 13
  • Biology of Aging -3 Some changes in aging process Nervous system : The nervous system demonstrates, possibly more clearly than any other system, the poorly defined borderline between normal, expected and tolerable changes due to aging and the pathologic changes due to disease
  • Slide 14
  • Biology of Aging -3 Some changes in aging process Neurochemical changes of aging include : Decreased availability of some major neurotransmitters (NEpi, Dopamine, GABA, Ach) and increased availability of MAO. These changes may be associated with specific psychiatric symptomatology.
  • Slide 15
  • Biology of Aging -3 Some changes in aging process Nervous system : Brain changes include: Decreased weight, enlarged ventricles and sulci Decreased cerebral blood flow Senile plaques and neurofibrillary tangles are present in all normally aging brain but these changes are exaggerated in Alzheimer type dementia
  • Slide 16
  • The aging brain
  • Slide 17
  • Biology of Aging -4 Some changes in aging process Skin and hair Muscles Special Senses Cardiovascular System Respiratory System Gastrointestinal Tract Urinary Tract
  • Slide 18
  • Biology of Aging -4 Some changes in aging process Psychological changes of aging include: Life stage issues Longevity and Existential issues Psychopatholgy and related problems Sleep pattern changes Alcohol-related disorders, and other psychoactive agents (including medication) Best to evaluate elderly in familiar surroundings
  • Slide 19
  • Biology of Aging -4 Some changes in aging process Psychological changes: Depression is the most common psychiatric disorder in the elderly. Losses (persons, social standing and utility value, health etc.) May mimic Dementia (pseudodementia) Suicide rate greater in elderly than in general population
  • Slide 20
  • Healthy Aging Healthy aging practices should begin early Factors associated with longevity Family history Continuation of physical and occupational activity Advanced education Social support system including supportive partnership

  • DEATH & DYING -1 DEATH is an inevitable link in the cycle of life It behoves us to prepare for this certainty (prepared or not it will visit upon us) Leveled, so to speak The glories of our blood and state Are shadows, not substantial things There is no armor against fate Death lays its icy hands on kings Scepter and crown must tumble down And in the dust be equal made With the poor humble scythe and spade - James Shirley
  • Slide 24
  • DEATH & DYING -1 A. CHILDS PERSPECTIVE 1. A childs response to death is based on his level of awareness. An awareness of the meaning of death becomes more concrete (7-11 reversibility and irreversibility) with developing comprehension abilities a. Children younger than 5 years tend to view death as abandonment They fail to appreciate the finality and irreversibility. Hence dont mourn fully these important individuals
  • Slide 25
  • DEATH & DYING -2 CHILDS PERSPECTIVE b. By middle childhood, a more realistic view of death begins to emerge, with children understanding the finality of the event. (1) The anxiety at this point about death concerns not only the loss of (separation from) loved ones but also fears of mutilation (castration anxiety) and suffering and pain
  • Slide 26
  • DEATH & DYING -3 CHILDS PERSPECTIVE 1b (2) Because of the egocentric thinking of children they tend to feel guilty and to view themselves as responsible for their own or others illness and death. Frequently the illness or death is viewed as a punishment for having been bad.
  • Slide 27
  • DEATH & DYING -4 CHILDS PERSPECTIVE 1c. By adolescence comes an adult cognitive view of death, and with it a clear understanding of its irreversibility. In addition, there is a capacity to mourn, especially by mid-adolescence. (1) Adolescents with chronic physical illnesses, eg cystic fibrosis, precociously develop a sense of finiteness to life, often living while waiting for the final stage
  • Slide 28
  • DEATH & DYING -5 CHILDS PERSPECTIVE 1c. (2). With a decrease in egocentricity of their thinking and a diminished tendency to see their illness or death as justified or deserved, adolescents experience alterations of resentment and despair as they struggle to accept their own death
  • Slide 29
  • DEATH & DYING -6 CHILDS PERSPECTIVE 2. Parental response to childs death. A childs death is certainly one of the most devastating experiences that could befall any parent. If the death is not a sudden one, there is a tendency for the parents unconsciously to undergo anticipatory mourning, resulting in the gradual relinquishment of strong emotional ties to the child. This can be hurtful to the child and parent alike
  • Slide 30
  • DEATH & DYING -7 CHILDS PERSPECTIVE 2a. The parent may be physically in attendance but emotionally disengaged and the child experiences the dreaded sense of abandonment The relationship becomes bland and lacks intensity as the parents try not to let the child see them upset An emotional barrier is erected, the talk is superficial, and the subject most on the childs and the parents minds becomes taboo
  • Slide 31
  • DEATH & DYING -8 CHILDS PERSPECTIVE 2b. When the child dies, the parents may feel guilty that they are not more upset by the childs death or that they may be relieved to have the ordeal over Unless properly counseled they may think of themselves as callous or non-loving when in fact they have already grieved, albeit unconsciously in advance
  • Slide 32
  • DEATH & DYING -9 ADULTS PERSPECTIVE 1. Adults tend to be anxious about their own death because of: The dread of being separated from loved ones Concern about pain and suffering, and Because of the narcissistic injury associated with the end of existence There is often also a sense of not having left an indelible mark on the world that will assure perpetual existence thereby avoiding a sense of nothingness.
  • Slide 33
  • The Process of Dying People die as they lived (cum defenses and all) Mortal man cant imagine his mortality Some investigators, particularly Elizabeth Kubler- Ross have proposed a series of five psychological stages through which the dying patient progresses These stages should be viewed only as representative of emotional reactions experienced by the terminally ill
  • Slide 34
  • DEATH & DYING -10 ADULTS PERSPECTIVE 2. Elizabeth Kubler-Ross: Describes five stages that the dying patient experiences before demise: a. The Stage of denial and isolation cant be, not true b. The Stage of anger with rage, bitterness, why me, etc The
