- Thinking (categorising, sequencing
28
what can impact cogniton
language, culture and educaiton
29
whats the difference between a cognitive screen vs cognitive assessment
Screen: to identify if general cognitive issues exists
Assessment: to find out specific problem areas so can plan intervention
30
what are 5 cognitive screening tools
- Clock drawing test
- MMSE
- RUDAS
- MOCA
- ACE- II
31
what is the social environment
availability of relationships, quality of interactions and community and societal attitudes and practices.
32
what is the physical envronment
: spaces where people do things, objects people use including assistive devices. Physical and cognitive accessibility, safety, sensory qualities and availability of space and objects.
33
what is the occupational environment
presence of occupational and activates that reflect the persons interests, roles, capacities. Qualities of occupations and activities and funding and policies that influence occupations and activities
34
whats the clock drawing test
- Clock drawing ability following a stroke is used to evaluate perceptual and cognitive impairments with dementia.
- Quick screening tool, not a diagnostic tool
- Key clinical variables cognition, functional independence, type of stoke, education level, age
- Involves the client correctly drawing and placing the hands and number on a clock face
- 11:10 is considered to be one of the most sensitive for measuring cognitive dysfunction.
35
how is the clock drawing test scored
- 1 for complete circle
- 1 for correct number order
- 1 for symmetrical and accurate number placement
- Score of three= no impairment
36
what errors on the clock drawing test indicate ALzhimeres disease
– perseveration, counter-clock- wise numbers, absence of numbers and irrelevant spatial arrangements or Stroke – spatial neglect, hemianopia, sensory loss
37
whats the mini mental state examination
- Most widely applied test for dementia screening but cannot be the sole assessment
- Scored form of cognitive mental status examination
- 5-10 minutes to administer
- Is standardised and validated
- Screening tool
- Evaluates adults level of cognitive functioning/impairment
38
how is the mini mental state examination administered
- Includes 11 questions
- First section involves verbal response only and covers orientation, memory and attention
- The second part tests ability to name, follow verbal and written commands, write a sentence and copy a polygon. This section is affected by people with severely impair vision
39
scoring of the mini mental state examination
- 27-30 normal cognitive functioning
- 21-26 mild cognitive impairment
- 11-20 moderate cognitive impairment
- 0-10 severe cognitive impairment
- *between a score of 0-17 it is considered unsafe for a person to be living alone

- Cut off core for dementia is 82-88/100
43
whats the MoCA
- Rapid sreening assessment for detection of mild cognitive dysfunction and mild dementia
- Not a diagnostic tool

44
whats the scoring for the MoCA
- Scored out of 30
| - 26 and above is normal
45
whats the RUDAS
- Short cognitive screening instrucment
| - 6 items: memory, visuospatial orientation, praxis, visuocontructional drawing, judhemnt, language
46
whats case management
is a means for improving clients' health and promoting wellness and autonomy through advocacy, communication, education, identification of service resources, and facilitation of service.
47
strategies used to structure the envionemtn to support the needs of a person with dementia

increase lighting to reduce falls risk
safer flooring
clear labels and signs
reminder devices
increase social activities and participation
```
48
2 assessment for dementia
standardised mini- mental state examination (SMMSE)

tuck mans 5 stage model of team development
```
forming
storming
norming
performing
ajourning
```
50
whats forming in tuck mans model of team development
Little agreement on team aims other than those received from leader. High dependence on leader for direction. Members try & establish their identity and make an impression.
51
whats storming in tuck mans model of team development
Clarity of purpose increases, but decisions don't come easily. Members vie for position, leader might be challenged. Cliques and factions form
52
whats norming in tuck mans model of team development
Beginning agreement on norms & practices (these may be +ve or –ve). Roles and responsibilities clear & accepted. Big decisions made by group agreement. Smaller decisions may be delegated. May engage in fun & social activities.
53
whats performing in tuck mans model of team development
Relies on the ‘norms’ established. Effective teams clear on tasks and roles. Members have a shared vision. Disagreements are resolved positively. Able to simultaneously work towards goals, and attend to relationship and team process issues to continue to grow.
54
whats adjourning in tuck mans model of team development
The break-up of the team, preferably when the task is completed successfully (or may be when members change), its purpose fulfilled; achievements celebrated. Some members may feel a sense of insecurity and regret loss.

56
factors inhibiting group decision making
1. Lack of group maturity: groups need time and experience working together to develop decision making. Can work to strengths
2. Uncritically giving ones dominate response: shortcutting the process of identifying possible alternative and going with the initial majority.
3. Social loafing: hiding in the crowd, a reduction of individual effort when working on tasks that need the summing together of individual input
57
whats vascular dementia
Second most common
Associated with problems in the flow of blood to the brain
Caused by occlusion of cerebral vessels
Multiple strokes in the brain that cause deterioration of mental capabilities
58
whats Lewy body dementia
Caused by neurodegeneration
Lewy bodies are small round inclusions found in nerve cells
Unsteady gait and balance, fluctuation in alertness, motor defects, cognitive impairments
