To truly understand how important and central memory is to us, it is important to understand what life is like for people who experience memory loss, or amnesia. This chapter examines the amnestic syndrome, which has been widely studied and the knowledge of which has significantly influenced theories of memory. The abilities and nonabilities of those with amnestic syndrome demonstrate that there are multiple independent systems of memory. The chapter also examines two controversial diagnoses, the main feature of which is memory loss dissociative identity disorder (DID) and psychogenic or dissociative amnesia. It discusses a form of memory loss that does not fit the technical definition of amnesia because it eventually affects not just memory but all cognition: Alzheimer’s disease (AD). AD is common among older adults and demonstrates how a worsening loss of memory and cognition can lead to a complete disruption of everyday life.

A psychologist must confront many prejudices against older adults that are manifested in most people in non-older adult cohorts. Clinical psychologists specializing in geropsychology work with individual older adults; family members of older adults, including spouses/partners, siblings, and adult children; and caregivers when treating the psychological problems experienced by older adults and dealing with issues of caregiving to older adults experiencing mental illness, dementia, and/or psychological reactions to co-occurring medical illnesses. Unfortunately, despite the fact that older adults are affected by the forces of ageism and stigma, and the fact that community psychologists strive to understand and improve social inequalities and to enable empowerment of marginalized people, there is a significant dearth of research in the field of community psychology. There are four types of ageism: personal, institutional, intentional, and unintentional. The majority of older adults have experienced age discrimination and stigmatization at some time after the age of 65.

This chapter talks about psychoactive substances that are commonly misused or abused by older adults. It is important for a psychologist to understand the psychopharmacological dynamics of each substance, how they are administered by an older adult, the symptoms of intoxication and withdrawal, and the psychosocial consequences experienced by the older adult misusing or abusing psychoactive substances. Unlike younger adults, older adults are more likely to avoid illicit substances such as cocaine, heroin, methamphetamine, psychedelics such as lysergic acid diethylamide (LSD) or mescaline, and designer drugs. Historically, the psychoactive substance of choice was alcohol. There are two general types of opioid psychoactive substances: naturally occurring opioids and synthetic opioids. Naturally occurring opioids include opium and its derivatives morphine and codeine, and heroin, which is a chemical manipulation of morphine. Unfortunately, many older adults suffer with chronic pain from cancer, arthritis, or injuries, causing a need for opioid medications.

The medical model of psychopathology currently guides psychiatrists and many psychologists who are treating older adults experiencing psychological problems. Use of this model causes contradictions and distortions for the treating clinician and limits the effectiveness of treatment for older adults experiencing psychological problems. There are three areas of concern that illustrate these contradictions and distortions. The first area of concern is the fact that only two classes of psychiatric diagnoses meet the characteristics of a disease. The second area of concern is how the current use of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) continues a tradition among psychiatry, managed-care companies, and insurance companies that puts pressure on psychiatrists, psychologists, hospitals, and psychiatric rehabilitation facilities to treat in the most cost-effective and short-term manner. The third area of concern is the relationship that has occurred between psychiatry and pharmaceutical marketing forces.

The heightened awareness of coming of death, and the anticipation of dying, results in many older adults experiencing an existential crisis. For some older adults approaching or in the age bracket of 75 to 84 years of age, the expectation of death becomes acute and triggers a need for end-of-life planning, also referred to as advance care planning. Palliative care is considered a good death because it keeps an older adult comfortable, provides counseling, and is a means to control pain that a dying older adult would otherwise experience. There is a significant need for psychologists to provide counseling to older adults experiencing disenfranchised grief because adults experiencing this type of grief suffer from difficulty experiencing their loss when it is not validated by others. Euthanasia is accomplished by an older adult’s request to his or her physician based on the intention of ending pain and suffering when terminally ill.

Psychologists work with micro-level and macro-level orientations. Clinical psychologists with a micro-level orientation focus on individuals, families, and small groups when performing psychotherapy. Community psychologists have a macro-level orientation. The aging population presents many opportunities for psychologists, both those engaged in scholarship and those working clinically with older adults, and for community psychologists addressing issues relating to social structures and organized communities of older adults, economic issues such as poverty and access to medical services, and issues relating to senior housing. Contemporary theory indicates that it is equally important for psychologists working with older adults to focus on the positive aspects of aging when addressing the psychopathological problems older adults are experiencing. Erikson’s stage theory originally had seven stages: basic trust versus basic mistrust; autonomy versus shame and doubt; initiative versus guilt; industry versus inferiority; identity versus role confusion; intimacy versus isolation; and generativity versus stagnation.

Online dating is becoming more and more common among younger people as well as older adults. There are many different websites that people interested in online dating can use or subscribe to nowadays. There are also many dating services that aim at a large part of the population and try to distinguish themselves by means of the particular matching services they offer or by the number of potential partners people have access to through their site. Throughout most of human history, until very recently, one's choice of dates was restrained by geography. In addition, there are biological approaches that can be used as a complement to dating websites and are often integrated into these sites. Often people move their conversations off the dating website relatively quickly and converse by e-mail or phone to get to know each other better.

As with most issues with media psychology, the travails of social media involve separating the hype from the truth. One of the curious things about social media is that, unlike some other previous forms of feared media such as rock music, rap, comic books, or video games, social media has been relatively effectively embraced even by older generations. This chapter discusses two corollaries regarding the duration and intensity of moral panics surrounding new technology and media. First, the degree and intensity of moral panics can be predicted by the degree to which they tap into existing moral concerns, such as sex, violence, or privacy. Second, the degree and intensity of moral panics are mitigated by the extent to which older adults embrace the new technology. As with many issues of digital privacy, it is one social media and Internet users will wish to consider carefully before they leap.
