Hearing Loss
Associated social isolation may increase the risk of depression and accelerate mental decline.
Individuals with hearing loss experience declines in memory, attention, and learning approximately three years earlier than those with good hearing; this deterioration is lessened with hearing aids.
Neurocognitive Disorders (NCDs)
Can occur due to small strokes, brain tumors, or alcohol use disorder, contributing to cognitive deficits.
Commonly referred to as dementia in older adults.
Risk factors include:
Heavy smoking in midlife.
Related to Alzheimer's disease, brain injury, or substance abuse.
Alzheimer's Disease
Progression involves:
Initial loss of memory followed by deterioration in reasoning.
Symptoms include emotional flatness, disorientation, loss of impulse control, and later, incontinence.
Neurological Mechanisms:
Includes loss of brain cells and degradation of neurons producing acetylcholine (a key neurotransmitter).
Accumulation of amyloid plaques disrupts neural communication.
MRI scans show greater brain activity in individuals at risk.
Predictive Measures for Alzheimer's
Development of brain scans and genetic tests may identify individuals likely to develop Alzheimer's.
There are ethical considerations around testing and timing for such assessments.
Life Transitions
Midlife transitions typically occur in the early forties, influenced by cultural timelines for marriage, parenthood, and retirement.
The social clock varies across eras and cultures.
Erikson's Stages of Development
Emphasizes intimacy (close relationships) and generativity (supporting future generations).
Successful functioning involves forming loving relationships and productive engagement.
Adult Commitments
Love:
Pair bonding is fundamental, focused on emotional support, and mutual interest.
Marriage correlates with happiness, sexual satisfaction, income, and mental health.
Data suggests cohabitation before marriage can lead to higher divorce rates than non-cohabitating couples.
Work:
Work provides identity and a sense of accomplishment.
Adults often define themselves by their profession or role in society, influencing their happiness and satisfaction.
Happiness:
Influenced by work context, relationships, supportive friends or family, and personal values.
Social interactions are crucial for happiness in both younger and older adults.
Positive and Negative Emotions
Positive feelings tend to increase after midlife, while negative feelings diminish.
Older adults report lower levels of anger, stress, and worry.
Trust and generosity may increase with age.
Biopsychosocial Influences on Successful Aging
Factors include:
Absence of genetic predispositions for decline.
Proper nutrition and active lifestyle—both mentally and physically.
A supportive social network and respect for aging in one's culture.
Safe living conditions enhance the aging experience.
Grief
Grief is more profound following unexpected deaths.
Separation from a partner often poses the greatest emotional challenge.
Engaging in social activities helps build resilience against grief.
Cultural Variance in Grieving
Grief reactions can differ culturally and individually; not all react predictably.
Surviving grief involves more than simply expressing emotion; support and time are significant in the healing process.
Erikson’s Late Adulthood Task
The psychosocial challenge involves developing integrity versus despair regarding one’s life and approaching death.
Misconceptions about Grief
Terminally ill individuals may not experience the despair expected; they often demonstrate resilience and positivity.
The healing power of time and social support is effective in navigating through grief.
Encouragement to explore deeper into developmental psychology topics in higher-level courses focusing on:
Child development.
Adolescent development.
Adult development and aging.
Death and dying courses.
