Q

Perimenopause

A

(~ late 40’s, early 50’s)
The beginning of menopause is usually characterized by 3 to 11 months of amenorrhea or irregular periods.
- Estrogen levels decline and lead to hot flashes
- The transition phase can last up to 6 years

Perimenopause means “around menopause” and refers to the time during which your body makes the natural transition to menopause, marking the end of the reproductive years. Perimenopause is also called the menopausal transition. Women start perimenopause at different ages.

Q

The difference between climacteric and menopause

A

Globally, the term menopause is much more frequently used than climacteric but, before we use either one, we should consider that ‘menopause’ is referring to a specific event, the cessation of menses, and ‘climacteric’ to gradual changes of ovarian function that start before the menopause and continue thereafter for a while.

18
Q

Physical Changes and Developments in Middle Adulthood

A
  • Presbyopia
  • Reaction time is slower
  • Lung & heart muscles shrink
  • Breathing capacity declines
  • Decline in aerobic capacity & max heart rate
  • Lean body mass decreases
  • Fat replaces lean tissue, and the basal metabolic rate declines
  • Strength decreases
  • Blood-sugar tolerance decline
  • Pancreas need to produce more insulin to achieve same effect
19
Q

Leading Causes of Death

A
  • Cancer (44%) & heart diseases (16%) are the two leading causes of death in Canada
  • 2 in 5 canadians will develop cancer
  • Shift from accidents to diseases as the main cause of death; Cancer and CVD (cardiovascular diseases)
  • men are more likely to have CVD and to die from it
  • Women have more diseases but live longer
20
Q

Cardiovascular disease (CVD)

A

Cardiovascular disease is the term for all types of diseases that affect the heart or blood vessels, including coronary heart disease (clogged arteries), which can cause heart attacks, stroke, congenital heart defects and peripheral artery disease.
- Most commonly results from arteriosclerosis
- Personality type A is related to CVD (Competitive, hostile, sense of time, urgency)

21
Q

Risk Factors for Cancer

A
  • Heredity
  • Problems in the immune system
  • Hormonal factors
  • Carcinogens
  • Smoking
  • Weight
  • Infections and chronic diseases
22
Q

Risk Factors for Heart Disease

A
  • Family history
  • high blood pressure (above 130)
  • high serum cholesterol,
    -smoking, a sedentary lifestyle
  • arteriosclerosis.
23
Q

What causes accelerated aging?

A
  • Sedentary behaviour
  • Lack of Sleep
  • Smoking
  • Fast/Junk Fiid
  • Stress
24
Q

What causes deaccelerated aging?

A
  • Exercise
  • Everyday activity
  • Sleep time & quality
  • Appropriate nutrion
  • Relaxation techniques
25
Q

The trend in white matter volume & age

A

The trend is comprised of a negative quadratic coefficient that causes the parabola’s ends to point downward. The peak in white matter volume is around 40-50 years.

26
Q

The trend in grey matter volume & age

A

Exponential decay slowly over time; grey matter volume starts at around 90-95 millimetres before reaching approximately 70 millilitres consistently.

27
Q

The trend in CSF volume & age

A

Linear increases over time; y-intercept is approximately ten years.

28
Q

Overall trends in the brain & nervous system in middle adulthood

A
  • Synapses continue to form (more are loss)
  • Areas that develop last are the ones that decline first
  • Frontal and parietal lobes begin to decline first
  • Exception of regions in the left temporal lobe associated with language
  • Middle-age brains respond more slowly than those of younger adults; Cognitive processing is less selective
  • Less ability to control attention process
  • Such differences are likely due to both primary and secondary aging
29
Q

Female Climacteric/Menopause Transition (Ages)

A
  • Premenopausal phase (~ late 30’s, early 40’s)
  • Perimenopause (~ late 40’s, early 50’s)
  • Postmenopausal phase
30
Q

Premenopausal Phase

A
  • Late 30s, early 40s
  • Estrogen levels begin to fluctuate and decline
  • Anovulatory cycles lead to lower progesterone levels
31
Q

Postmenopausal Phase

A
  • Estrogen and progesterone drops to low levels and menstruation ceases
  • Women produce less vagina lubrication and vaginal walls thin
  • Findings of psychological effects are mixed
32
Q

Male climacteric

A
  • Extremely gradual and slow
  • The quantity of viable sperm produced declines slightly
  • Enlargement of the prostate gland
  • Very slow drop in testosterone
  • Erectile dysfunction
  • Taking testosterone to combat this: Benefits are not proven and maybe increase risk of prostate cancer
33
Q

Discuss Sexual Difficulties in Middle Adulthood

A
  • Remain sexually active, but frequency drops
  • Cannot be explained only by a drop in hormone levels
  • Women produce less vagina lubrication, and vaginal walls thin
34
Q

Mental Health in Middle Adulthood

A
  • Mental health improves with age
  • Self-esteem peaks around age 60
  • Depression is the most common mental health issue in middle-aged adults
  • Substance abuse is also a growing issue in middle adulthood; specially opioid-related drug use
35
Q

Selective Optimization With Compensation

A

A strategy for improving health and well-being in older adults and a model for successful aging. It is recommended that seniors select and optimize their best abilities and most intact functions while compensating for declines and losses.
- Is the theory developed by Paul and Margaret Baltes, that people try to balance their lives by looking for the best way to compensate for physical and cognitive losses and become more proficient in activities they can already do well.

36
Q

Denny’s Model

A
  • Age-related changes follow a typical curve on nearly any physical or cognitive functioning measure.
  • This curve’s height varies depending on how much an individual exercises some ability or skill.
  • Unexercised abilities have lower peak performance. Exercised abilities have a higher peak.
  • For Ex. when adults persist with challenging and engaging cognitive training, such as starting a new hobby or craft or acquiring and using new strategies to solve problems, they maintain or improve their cognition.
  • Performance peaks in middle adulthood.
    TLDR: Challenge yourself, exercise unused skills, and improve cognition.
37
Q

How does crystallized and fluid intelligence relate to Denney’s Model?

A

Crystallized abilities are at least moderate exercise, but fluid abilities are unexercised.
Whether abilities are crystallized or fluid, those that are exercised more often will have a higher peak.

38
Q

What does the gap between the curves for unexercised and exercised abilities mean?

A

It represents the degree of improvement that would be possible for any given skill if only we would exercise those skills.

39
Q

Intellectual Development in Middle Adulthood

A

Shows multi-directionality, inter-individual variability, and plasticity.
Development of expertise
* Developed through attention and practice
- Experts rely on experience and intuition
* Beginners rely on formal procedures and rules
* Behaviour becomes automatic
- Do not need too much thought
- Compensate for losses in reaction time
* Better strategies when compared to non-experts
- Use of different neural pathways to solve problems

40
Q

Short-term & Working Memory

A

The capacity to use it efficiently declines with aging.
- Short-term memory refers to the memory systems in the brain involved in remembering pieces of information for a short period, often up to 30 seconds. Short-term memory creates a kind of “visuospatial” sketch of information the brain has recently absorbed and will process into memories later.
- Working memory is the small amount of information that can be held in mind and used in the execution of cognitive tasks.

41
Q

Long-term Memory

A
  • Semantic memory (general knowledge): Semantic memory refers to the memory of meaning, understanding, general knowledge about the world, and other concept-based knowledge unrelated to specific experiences.
  • Remains stable or even increases
  • Episodic memory: Episodic memories are what most people think of as memory and include information about recent or past events and experiences, such as where you parked your car this morning or the dinner you had with a friend last month.
  • Remember personal events
  • Declines, but the use of cues can compensate for it
42
Q

Goleman’s four stages of creativity

A
  1. Preparation: Important info is gathered
  2. Incubation: Digesting the info
  3. Illumination: The solution becomes clear (“aha!” moment)
  4. Translation: The solution is applied, and adjustments are made
