Q

Executive functioning

A
  • Reasoning, decision making, problem solving, judgement, abstract thought, and logic
  • Significant differences from younger to older
  • Differences seem to be greater as task complexity increases and as additional cognitive resources are needed

Q

Language production and speech comprehension

A

Older adults OUTPERFORM younger in message production and discourse (storytelling)

24
Q

Wisdom

A

Do not know if this changes or remains the same with age

25
Expertise
High level of skill/knowledge in one area- problem solving, reasoning, memory - Maintains in later life and compensates for other deficits
26
Implicit processing
Unintentional, occurs without awareness, requires minimal cognitive resources, minimal change young to old
27
Explicit processing
Intentional, occurs with awareness, effortful- requires moderate to substantial cognitive resources, some age related decline
28
Intellectual abilities
Fluid intelligence- ability to use abstract reasoning, decline begins around age 70 Crystalized intelligence- accumulation of knowledge, experience, increase throughout life and maintains in old age
29
Optimizing cognition in later life
Physical activity, mentally stimulating activities, social engagement
30
Mild cognitive impairment (MCI)
The changes in memory and other areas of cognitive function that may be seen in healthy older adults
31
Impact of MCI on daily activities
Not a strong impact, still can complete ADLs and IADLs
32
Impact of MCI on leisure activities
Does not impact- however engagement in leisure has been found to have positive impact on cognition
33
Most common form of dementia
Alzheimer's dementia 5.2 million living with AD
34
What is dementia?
- Can't meet everyday demands of life - Affects cognition, behavior, and occupational performance - Irreversible condition - Memory loss not always first sign - An acquired, persistent impairment in multiple areas of functioning not due to delirium
35
Impact dementia has on behavior and occupational performance
- Deterioration in day to day functioning - Ability to engage in meaningful occupation - Safety concerns
36
Impact dementia has on family
- Increased stress on informal caregivers - Financial situations
37
Delirium
Alteration of mental status characterized by an inability to appreciate and respond normally to the environment
38
Difference between delirium and dementia
Delirium is often reversible, viewed as a medical problem that can be diagnosed and treated
39
Causes of delirium
- Thyroid disorders - Urinary Tract Infection (UTIs) - Electrolyte imbalances - Hormonal imbalances - Normal Pressure Hydrocephalus (NPH) - Tumors - Stroke - Intoxication - Withdrawal from substances - Depression - Systemic Illness (kidney, cardiac) - Other infections - End stage liver disease
40
____% of dementias are due to delirium, other ____% are other types
13%, 87%
41
Other types of dementia
- Alzheimer’s disease - Vascular Dementia - Frontal-temporal Dementia - Lewy-body Dementia - Korsakoff’s syndrome - Huntington’s disease - AIDS related - Parkinson’s with Dementia - Multiple Sclerosis
41
Other types of dementia
- Alzheimer’s disease - Vascular Dementia - Frontal-temporal Dementia - Lewy-body Dementia - Korsakoff’s syndrome - Huntington’s disease - AIDS related - Parkinson’s with Dementia - Multiple Sclerosis
42
Cause of vascular dementia (VaD)
- Result of cerebral vascular damage - Single brain infarct or multiple lesions - Changes to white matter
43
Subcortical ischemic vascular dementia (SIVD)
Numerous discrete subcortical lesions
44
Vascular cognitive impairment (VCI)
- Changes that occur due to vascular lesions (cognitive) - Can be treated, doesn't always turn into VaD - Recognition of VCI may allow for early diagnosis/intervention
45
Hallmark of VCI and VaD
Dysexecutive syndrome- problems with attention, working memory, planning, sequencing, abstraction
46
Who is at risk for VCI or VaD?
Advanced age, male, history of stroke, hypertension
47
Cause of dementia with Lewy bodies
- Presence of lewy bodies→ damaged nerve cells, amyloid and plaque formation similar to AD - Hallmark → round neurofilament inclusion bodies that contain damaged nerve cell deposits
48
Core features of DLB
- Hallucinations - Parkinsonian symptoms - Cognitive fluctuations COG BEFORE MOTOR
49
Age onset of frontotemporal dementia
57 years, insidious onset with slow progression
50
Symptoms of FTD
- Changes in personality→ casual but prominent - Behavioral disturbances and changes in social interaction - Failure to demonstrate basic emotions - Difficulty regulating behaviors
51
Parkinson's disease with dementia
Typically develops slowly... cog skills diminish first Other than TIME SEQUENCE of symptoms there are no distinguishing factors between PDD and DLB
52
Alzheimer's disease
- Most common form - Intellectual impairment/behavior and personality - Irreversible and progressive - Advancing age is risk factor - Diagnosed when individuals demonstrate onset of hallmark feature *impaired memory* as well as deficits in one other cognitive domain
53
Pathology of Alzheimer's disease
- Brain shrinks over time
54
Diagnosis of Alzheimer's disease
Must demonstrate a decline in three or more of the following: - Memory - Language - Perception (especially visuospatial) - Praxis - Calculations - Conceptual or Semantic Knowledge - Executive Functions - Personality or social behavior - Emotional awareness or expression
55
T/F Most of the AD population is female
True
56
Dementia risk factors
- Increasing age - Female - Black - Having family history of dementia - Serious head injury with loss of consciousness - Genetic factors
