Early and middle adulthood involve significant physical, cognitive, social, and emotional changes. In early adulthood, individuals focus on developing relationships, careers, and identity. Physical health is usually at its peak. In middle adulthood, priorities shift to parenting and career goals while physical decline begins. Health risks increase so preventative care is important. Successfully navigating developmental tasks such as intimacy vs isolation and generativity vs stagnation is key to well-being. Late adulthood involves further physical and cognitive changes along with socioemotional adjustments. The aging process, death of loved ones, and changes in roles present challenges but can be positively addressed.

Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.

Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:

2. Learning Targets
• Identify and discuss changes in the 4 domains
of development for early and middle
adulthood.
• Discuss health concerns and health
maintenance activities important in early and
middle adulthood.
3. Early Adulthood Key Points
• Depends on the person, but usually between 20-
40 years of age.
• Physical development is complete, and most
people are at peak health physically.
• Important events include developing
relationships, a career, and solidifying
beliefs/identity.
• Challenges include successfully transitioning into
new independent roles, roles related to
marriage/parenting.
4. Early Adulthood: Physical
Development
– Physical development and growth are mostly
complete.
• Adults in this stage reach their physical peaks in
strength and endurance.
• This is considered the safest time statistically for
healthy pregnancy and birth (earlier and later have
increased risk).
– Lifestyle disease usually has not had a chance to
set in at this point.
– Dangers related to high risk behavior drop off
significantly after the early 20’s.
5. Early Adulthood: Cognitive
Development
• As previously discussed, the brain continues to
develop into the mid twenties.
– Intellectual peaks are usually reached around this
point.
– Young adults still find it easy to learn new skills
and information.
• Relativistic thinking emerges:
– Adults engage in more thinking about complex
issues and are able to see gray areas and multiple
levels of a problem in an abstract way.
6. Early Adulthood: Developmental Tasks
(Erikson)
• Intimacy Vs. Isolation
– Self identity is established, but evolving
– Young adults seek connection with similar minded
peer group
– Differs from adolescence (peers shape you)
– Pursue romantic partner to establish “family”
– Learns commitment (based on trust and self
confidence learned in childhood)
7. Socioemotional Development in Early
Adulthood: Kohlberg’s Moral Development
• Most young adults stay in the Conventional Stage
of moral reasoning.
– Review: internalize social ideas of morality,
understand the function of morality and law/order in
maintaining a society.
• Some adults (at any stage of adulthood) may
graduate to a Post-Conventional moral reasoning.
– This incorporates a deeper and more complex
understanding of universal rights and wrongs.
– This individuals have a strong moral compass and
confidence to stand up to pervasive injustice.
8. Relationship Skills: Compatibility
• Compatibility is a combination of social,
emotional, and physical factors that create a
situation where partners “fit” together.
– May include things such as physical attractiveness,
similar hobbies and interests.
– Most important (statistically): similar world view,
life goals, intelligence, beliefs about faith and
politics, temperament.
– Sometimes, opposites attract and it all comes
down to the individual.
9. Adjusting to Roles and Finding
Happiness
• Marriage/Co-living: the young adult must adjust and learn
commitment and compromise to obtain this state of
intimacy.
– Adults who lack a clear vision of their own identity will struggle
here due to low self confidence, issues with jealousy, rigidity,
etc.
• Career Pathway: At some point, must make choices and
take steps to establish a vocation (or will end up “drifting”).
– Same issues with identity.
• Adjusting to Parenthood: Whether single parenting or co-
parenting, taking on the care of another is challenging.
– Must learn to adjust expectations of independence, control of
schedule, and priorities.
10. Middle Adulthood: Key Points
• Ages 40-65ish, focus is on parenting, career,
meeting goals.
– Female fertility ends, physical aging begins in both
genders
• Health concerns become more prevalent:
– Healthy lifestyle to prolong healthy years and prevent
disease
– Preventative care especially important
• The “Midlife” Crisis is Common
• Mental flexibility becomes limited, learning new
skills and changing habits harder.
11. Physical Changes in Middle Adulthood
• Physical Decline begins:
– Depends greatly on lifestyle choices.
– Fall from peak fitness by mid to late 30’s
– Women have onset of menopause in mid to late
40’s/early 50’s
• Lifestyle issues are catching up:
– Poor lifestyle choices may now lead to disease and
chronic health issues.
• Preventative care is very important:
– Many chronic diseases and concern can be treated
early if caught during this stage.
12. Cognitive Change in Middle Adulthood
• Still in Formal Operations.
– Same level of intelligence as reached in early adulthood.
– May have more difficulty learning new skills and
information.
– Benefit from experience of applying knowledge to
situations.
• Often able to handle stress and problems with less
difficulty due to experience.
• May become mental “rigid” if brain is inactive.
– Middle adults who read and problem solve often are less
likely to have dementia at an early age.
13. Middle Adulthood
• Social Changes:
– Peer group becomes increasingly important as children
move out and own parents die.
– Marriage is often at a make of break point due to “empty
nest.”
• Developmental Task:
– Generativity Vs. Stagnation
• Develop sense of purpose by seeing goals come to realization:
– Children grow up
– Career is at peek
– Other goals academically, artistically, or socially are met.
• If not, the sense of productivity and esteem is lost.
14. The Middle Life Crisis
• This occurs due to major changes from the routine or
lifestyle conducted during early adulthood.
– In early adulthood, everything is on the “up”.
• Family is growing
• Career in developing
• Marriage is family centered, as is socialization.
– At middle adulthood, the focus often shifts back to the
individual.
• Children no longer dependent.
• Career is stable or (worse) declining/boring.
• Marriage now returns to spouse centered.
• May have insecurities related to physical changes.
• Any previous issues with identity are going to resurface.
15. Success in Middle Adulthood
• Keeping the Picture “Big”
– Adults who stay focused on healthy relationships with
their significant other and children are happier as they
reach later adulthood and retirement.
– Adults who are engaged in social activities and
meaningful hobbies are less likely to feel stagnant and
bored in later life.
– Intellectually active adults are happier and healthier.
– Adults who protect their health earlier in life will
benefit from better health with aging.
17. Key Points for Late Adulthood
• Many elderly (age 65 plus) and aging adults have
socioemotional difficulty in our culture due to a
focus on youth, and lack of value for elderly.
• Physical aging process will impact ability to
engage in previous activities at some point.
• In America, we have an aging population (more
than 1/5th of the population by 2030) so concerns
of the aging will dominate as market and political
forces.
18. The Physical Process of Aging
• In optimum condition, the organs of the
human body will ultimately fail at the
MAXIMUM point of about 115 to 120 years.
– Because we do not live in optimum conditions,
aging occurs for most of us at a faster rate and
leads to tissue failure and dysfunction.
– Our body cells have a built in mechanism to cease
cellular replacement which leads to natural
process of aging.
19. Experiencing the Aging Body and Mind
• As the natural biological process of aging occurs,
people will experience the following. The rate
depends greatly on lifestyle, environment and
genetics.
– Skin and hair will became less vibrant (slower rate of
cellular replacement)
– Kidneys, heart, blood vessels, and other organs begin
to wear out.
– Skeletal system and muscles may have degeneration,
weakness.
– Mental flexibility will become reduced, difficulty
forming new memories may occur.
20. • Adjustment:
– Decline in health generally mean that the older adult
must discontinue some of their previous activities and
lifestyle.
• Mentally, they are still the same person.
– It is a common misconception that elderly people do
not have the same emotions, desires, and needs as
younger adults.
• Evolving Self Image
– Adults at this life stage face the challenge of
remodeling their identity to fit their new social roles,
or becoming detached and depressed.
Socioemotional Consequences of
Aging
21. Cognitive Changes in Older Adults
• Biologically, many older adults may loose
some flexibility or ability due to aging.
– This often leads to society's perception that older
people are stupid, or childlike.
• Dementia
– This is a common illness in the elderly that effects
the ability to recall old information and form new
memories. It can impair the person’s ability to live
independently.
22. Socioemotional Development:
Erikson’s Task
• Integrity Vs. Despair
– A successful transition into “elderly status” involves
being satisfied with your life’s accomplishments,
having strong ties to family or social supports, and
embracing the new social role that you fill (retiree,
grandparent, widow/er). This involves “letting go” of
the realities of your previous life and moving on.
– Despair develops in adults who have low esteem
regarding their life, poor sense of identity, or social
dysfunction that leaves them isolated form support.
These adults will often be angry, careless, and
depressed.
23. Social Challenges Faced in Late Life
• Death of Spouse and Friends
– As we age, people will die. This can be very difficult, as we
loss the people who have been our social support system.
• Retiring
– Though this is looked forward to by many working adults,
letting go of a title or position that was worked for for
many years can cause uneasiness and lead the retiree to
feeling lost or unproductive.
• Grandparent Status
– Parents must adjust to the fact that their children now
carry the roles of parent, and they have to find the
appropriate style of grand parenting that fits their lifestyle.
24. Ageism and Myths About Aging
• Ageism is the mistreatment
or discrimination against
older people based on
beliefs about the elderly
population. This is caused
by many myths about the
elderly.
• Myths About Elderly
People:
– They are less intelligent.
– Older people are no longer
interested in hobbies,
activities, etc.
– Older people no longer have
romantic/sexual needs.
– All old people have significant
health problems, memory
loss, etc.
– All people age in the same
way, and have the same
needs.
25. The End of Life
• In our youth focused society, poor care is
often given to the dying due to a fear of
death, and avoidance of the topic.
– People reaching the end of life often need to
express and discuss feelings related to mortality
and death.
– There is an emotional process associated with
death and dying.
26. Key Points – End of Life
• Process known as Stages of Dying (emotional)
occur in expected deaths.
• The body may show certain physical signs of
decline in the days and ours preceding death.
• Hospice is a health care specialty focusing on
terminally ill patients and their families.
• Holistic care is especially important in
healthcare, and in doing what we can to
ensure a “good” death.
27. Stage of Dying (Elizabeth Kubler-Ross)
• Denial
• Anger
• Bargaining
• Depression
• Acceptance
• Not all people go
through all stages or at
any specific rate.
28. Denial
• Often the first reaction at learning that death
is going to occur sooner rather than later.
– The person may not acknowledge the information
they have been given.
– They may insist on continuing regular activities.
– They may withdraw socially.
– They will likely refuse to talk about the illness or
process.
29. Anger
• After they process through the initial denial,
the person may become angry.
– They may place blame on loved ones, healthcare
providers, or higher powers.
– They often ask “Why me?”
– They may be envious of close loved ones for their
health.
30. Bargaining
• As Anger subsides, the person may try to “find
a solution”
– They may reach out for more or different
healthcare.
– People often go to spiritual healers or alternative
medicine.
– They may seek spiritual guidance to plea for their
cure.
31. Depression
• Once it is clear and accepted that bargaining
will not work, the person may experience a
period of intense and deep depression.
– They fear the separation from family, and of the
unknowns that surround death.
– They may fear pain.
– They will socially withdraw.
– This stage can be the most difficult for family.
32. Acceptance
• Hopefully, following depression, the person
can find acceptance in mortality.
– They are able to emotionally and spiritually find
peace in the inevitable.
– At this point, they are able to reflect on their lives
in a positive and joyful manner and connect with
family to say goodbye.
– Acceptance is necessary for a “good” death.
33. Hospice Care
• Hospice is a holistic specialty in healthcare
that focuses on proving terminally ill people
with the best quality of life possible, and in
caring for their families.
– Nurses, doctors, CNAs, therapist, chaplains,
volunteers and social workers all provide hospice
care.
– Focus is not on quantity of life, but on quality.
