Q

What is vascular dementia?

A

Dementia caused by reduced blood supply to the brain due to diseased blood vessels.
–> heart problems –> due to diet? so some change can be achieved if changes made to diet.

(blood is delivered to the brain through vascular system)

vascular system damaged (leaked/blocked) –> blood can’t reach brain –> brain cells die –> memory and cognition problems.

  • effects of brain cell death can be subtle at first, but builds up.

Q

What is parkinson’s disease?

Q

What are some characteristics of people with parkinson’s with dementia?

Study These Flashcards
A
  • deficits in executive func, visuospatial ability
  • irritability
  • memory problems (not the initial feature for many though)
18
Q

What is a stroke?

Study These Flashcards
A

Sudden disturbance of the nervous system, caused by distruption of blood supply to the brain.

  • Ischaemic stroke
  • Haemorrhagic stroke
19
Q

What is an ischaemic stroke?

Study These Flashcards
A

A blockage in one of more of the arteries carrying blood to the brain

20
Q

What is a haemorrhagic stroke?

Study These Flashcards
A

Artery burst –> bleed in brain –> also kills brain cells

21
Q

What are signs of a stroke?

Study These Flashcards
A
  • paralysis in face, limbs - especially on one side of body (hemiplegia)
  • dizziness, trouble walking, loss of balance
  • numbness or weakness. Drooping of one side of face
  • difficulty swallowing
  • confusing, difficulty speaking or understanding speech
  • visual disturbance in 1 or both eyes
22
Q

What is delirium?

Study These Flashcards
A

A state of mental confusion that can occur as a result of illness, surgery or medication.

It starts suddenly, can be frightening, and is reversible.

23
Q

How long can delirium last?

Study These Flashcards
A

onset can take hours or days..like a stroke.
Fast onset compared to dementia.

but can last..

  • acute - hours to days
  • persistent - weeks to months
24
Q

What are are possible causes of delirium?

Study These Flashcards
A
  • Medical condition: infection of bladder, chest or brain, fever, dehydration
  • substance withdrawal/intoxication
  • medication
  • major surgery
  • terminal illness

It is non-reversible if you don’t treat it in time. Fast onset compared to dementia.

25
What are symptoms of delirium?
``` Diminished awareness of surroundings Inability to understand conversation/speak correctly drowsiness mood swings confusing that worsens in evenings agitation, restlessness auditory hallucinations vivid dreams that continue once awake ```
26
What is the psychologist's role in neurocog disorders?
- Early detection of MCI - Support to caregivers - recommendations for supports and strategies - reassesment
27
Give an example of a test used for alzheimer's
MMSE - mini-mental state examination - clock drawing test - house copying test - montreal cognitive assessment - LESS AFFECTED BY EDUCATION
28
What is TBI?
Falls/Traumatic Brain Injury. - Greater increase among elderly (65+), but also present in young people. - Happens when there is a jolt or impact causing brain to be shaken around in skull. older people - falls younger people - sporting, car, bike injuries.
29
Effects of Traumatic brain injury?
- functioning outcomes were worse in elderly than young people: feeding, locomotion, expression - higher rates of mortality in elderly - same outcomes even when less severe - older individuals more likely to have increased dependence post injury - can be associated with dementia
30
What is post concussional disorder?
- history of head trauma - difficulties with attention or memory - 3+ of: fatigure, sleep disturbance, dizziness, anxiety, depression, apathy, personality changes etc. Lots of these symptoms are also symptoms of aging, so it is often dismissed by clinicians.
31
What are trends in mental health in later life?
- psychiatric disorders may decrease in prevalence in later life - declines in memory, associated w/ normal aging are small - increase in wisdom and other skills - better coping strategies for managing distress - some people have a more productive meaningful later life, as they have more active roles. or maybe older people just don't report the problems... because it's expected....
32
How does late life depression differ from early onset depression?
- FIRST EPISODE AFTER 60 YRS - more cog dysfunction - increase comorbodity of medical illness - greater fatigue and agitation - less likely to have family history of depression - serious suicide concern use geriatric scale to measure --> removes physiological questions.
33
List some differences between depression and dementia in
onset: rapid in depression, insidious in dementia duration: short for depression, long for dementia mood: depressed vs. fluctuating self-image: poor vs normal reason for consultation: self referral vs. family referral family history differs
34
Anxiety in older populations?
- more common than depression in older people. - phobia most common, GAD less common. - OCD and PTSD not common - more common in females problem is that the symptoms mimic the symptoms of other medical conditions
35
Alcohol and substance disorders in older individuals?
- will expected to become more prevalent among older people with time - unreported substance use increases risk of negative interactions with medications - comorbidity of mental disorders and substance abuse:: 20% of people receiving outpatient mental services and 37% receiving inpatient mental health services.
36
Barriers to a more proactive response to elder abuse by health care providers?
- lack of comfort with the issue - lack of training and information on the prevalence and health impact of abuse - perceived lack of time to address problem - lack of confidence in referral agencies - lack of formal protocols and institutional support for responding
37
Examples of older abuse?
- psych/emotional - cause distress, anger, threats of bodily or sexual abuse - sexual - physical - infliction of pain - withholding or too much medication - neglect - partner abuse or through other family members - societal abuse
38
Factors that can increase likelihood of elder abuse?
- family undergoes unfavourable change in circumstances - history of poor relationships between family - difficulties emerge as result of role reversal - carer forced to change lifestyle as result of caring - carer has not received help or support - financial pressures
39
What are examples of elder abuse and neglect?
- malnourishment / dehydration - hypothermia - weight loss with no apparently medical cause - lack of safety precautions or supervision - poor personal hygiene - poor clothing choices - inappropriate for weather - medicines not purchased or administered - no social, cultural, intellectual or physical stimulation etc
40
What are examples of self-neglect
- inappropriate eating habis - malnourished - filthy and unhealthy living habits - absence of basic hygiene - reclusive - frugal - fear, distrust
