A

maintains focus on relevant information without interference from irrelevant stimuli. Sustained attention requires control over internal and external competing stimuli.

Q

what is selective attention

A

maintains attention in the presence of conflicting or competing sensory information. To facilitate or direct thoughts and actions, whilst simultaneously inhibiting our response to interference. Eg looking at an item on the shelf will you be distracted by prices, brands etc

Q

strategies to improve attention and concentration

A
  • ‘Put blinkers on’ by reduce all possible distractions in the environment

Q

why is understanding neglect important for Occupation Therapy

A
  • Major factor limiting occupational performance in Stroke rehab
  • People with ULSN have more trouble resuming usual daily activities

Q

whats embolic stroke

A

if the blood clots forms somewhere in the body, it can travel in the blood stream to the brain. It gets stuck there and stops blood from getting through

Q

whats thrombotic stroke

A

: over time plaques increase in the blood vessels and narrow or blow the artery and stop blood getting through. Eg TIA stroke “mini stroke” signs may disappear after 24 hours but often a warning sign that a stroke may occur.

– visuo-motor organization – thinking operations.

49
Q

symptoms of neglect

A
  • The inability to detect stimuli in the affected visual field, opposite to the damaged area of the brain.
  • Lack of ability to attend to stimuli in the three spatial fields personal, peri-personal and extra personal.
  • A spontaneous deviated head or eyes towards the non-affected side.
  • Impairment in features of copying and writing
50
Q

whats the three spatial sectors

A

personal (bodily space)
peri personal (within reach)
extra personal space (outside of reach)

51
Q

whats personal neglect affect

A

the patients’ surface of their body. This type of neglect affects bodily functions and can be described as if the person has forgotten about the side of the body affected by neglect. This leads to a number of issues with daily activities and can result in symptoms such as impaired swallowing, dressing and bathing occupations. In some cases, it has seen to affect the inside of the mouth with loss of saliva production on the left side.

52
Q

what’s peri-personal neglect affect

A

is more common than personal and refers to the visual deficits in reaching distance of the patient. While extra personal neglect refers to failing to respond to stimuli such as objects or events outside of the patient reaching distance

53
Q

long term opis for stroke patients

A

Most recovery occurs during the first weeks following the stroke
Bogousslavsky (2002) mentions that issues that may still be impacting on the survivor include;
Hemiplegia
Continued apraxia
Motor neglect
Affective mood disorders
Stroke can also lead to vascular dementia later in life

54
Q

whats hemianpia vs neglect

A

hemianopia: is blindness over half of the visual feild
Neglect: unaware of objects or people on one side of their body can still see

55
Q

how to test is it neglect or hemianopia

A

finger test:
wiggling a finger on each side of the hemisphere if they can recognise when one is moving indivudiaully but unable to if they both are moving this means that they have neglect

56
Q

whats the motor model

A

Two approaches: Neurodevelopmental approach and contemporary approach

57
Q

what areas are affected if there is a MAC infarct

A

These regions include the parietal lobe, the temporal lobe, and the internal capsule and thalamus.

58
Q

prognosis for someone experiencing middle cerebral artery infarct

A

patients with large MCA infarct is poor, with case fatality rates in previous intensive care-based series of nearly 80%. In the modern era, which several recanalization therapies were applied at the very early onset of stroke, the prognosis of these patients would be better.

59
Q

Mca stroke symptoms

A

Deficits in movement and sensation (contralateral hemiplegia and hemianesthesia)
Difficulty swallowing (dysphagia)
Uninhibited neurogenic bladder
Impaired language ability, including global aphasia, Broca’s aphasia, and Wernicke’s aphasia
Impaired vision and partial blindness (hemianopia)
Poor awareness of deficits
Headaches
Inability to turn eyes towards the affected side

60
Q

what’s the anterior cerebra artery supply blood to

A

frontal lobes

61
Q

whats the middle cerebral artery supply blood to

A

frontal lobe, temporal lobe and parietal lobe

62
Q

whats the posterior cerebral artery supply blood to

A

occipital lobe and temporal lobe

63
Q

explain the impact stoke on a persons occupational performance

A

• Self-care
→ Dysphagia (difficulty swallowing) makes it unsafe/difficult to eat
→ Neglect affects dressing, grooming, eating etc.
→ Decreased upper limb function impacts on ADLs
• Productivity
→ Neglect impacts on work and household tasks
→ Cognitive deficits (eg. inattention and memory problems) could make it difficult to work
→ Vision deficits

64
Q

what type of stroke is an cerebral artery infract

A

ischaemic stoke as its blocked by a clot

65
Q

whats an Cerebral artery infract

A

• An MCA infarct is a type of stroke that occurs when the MCA artery becomes blocked

66
Q

risk factors for a MCA infract

A

→ Lifestyle (eg. smoking, being overweight, physical inactivity, excessive alcohol consumption)
→ Medical (eg. high BP, heart disease, high cholesterol, sleep apnea, age, family history

67
Q

describe the cognitive model

A

• The cognitive model describes how people’s perceptions of, or spontaneous thoughts about, situations influence their emotional, behavioral (and often physiological) reactions
