28
Q

What are the characteristics of Alzheimer’s

A

Cognitive impairments in short term memory, aphasia, apraxia, agnosia
irritability and paranoid behaviour
Average duration 9-10 years however it is difficult to ask someone how long problems have been going due to tendency to remember catastrophic events

29
Q

Risk factors of Alzheimer’s

A

Age (old), gender (f), genetics (58-76% heritability, Gatz et al, 2006)
family history of dementia
history of head injury
Low educational status (SES) . speaking 1 language

30
Q

What is longitudinal assessment and why?

A

Assess someone every 6 months. comparing their performance with themselves (best form of control) Shows if things are getting worse and how quickly condition worsening. Decline is non linear can see improvements and worsening. (do something on a Monday but cant on a Tuesday)

31
Q

Aetiology of Alzheimer’s

A

Beta Amyloid Plaques- nun study

32
Q

Mild cognitive impairments

A

Patients think they’re experiencing cognitive decline but scores low but not super low. can eventually lead into Alzheimer’s

33
Q

MMSE

A

Assessment tool for measuring cognitive decline. An issue is that already smart people may not show up as cognitively declined as higher baseline.

34
Q

Parkinson’s diseases characteristics

A

White matter disease affecting movement. main symptoms are tremors, slowness of movements, stiffness or rigidity of muscles. Occurs as a result of damage dopaminergic neurons in substantia nigra area of basal ganglia

35
Q

Huntingtons disease

A

Inherited degenerative disorder of the CNS (50%). Movement disorder however cognitive ability declines as disease progresses. causes cell death in basal ganglia.

36
Q

What is the basal ganglia?

A

Interconnected nuclei beneath frontal and temporal lobes. receive input from cortex. two parallel pathways (go/no go). Contributes to acquisition, selection, inhibition and cessation of rewarding vs non rewarding behaviour.

37
Q

Cortico basal degeneration

A

Motor control issues, limb apraxia. cognitive dysfunction in frontal and parietal cognitive problems.

38
Q

Multiple sclerosis

A

Hyperactive, maladaptive autoimmune system. Mylein sheath (protector of nerve cells) breaks. can impact teenagers. Maladaptive impact dependant on variant of MS

39
Q

What are the main forms of neurological disease?

A

Alzheimer’s
Parkinson’s
Huntington’s
cortico basal degeneration
Multiple sclerosis

40
Q

Posterior cortical atrophy

A

Affects back of brain (visual processes). lose ability to read, recognise colours, faces. Often dissmessed as problem with eyesight.
Tang Wei (2004)

41
Q

Why is assessment important?

A

Determining nature and profile of any defecits.
Provide information about onset, severity, prognosis, and progression of symptoms
Helping to discriminate between neurological and psychopathological symptoms
Helping to identify focus for rehabilitation programs.
Can understand which area of the brain is damaged
people find comfort in knowing what is happening to them.
Experiencing something without explanation can be difficult on patient and family

42
Q

What are the categories of impairments of neurological disorders?

A

A attentions and arousal
M memory and learning (Amnesia)
P Perceptual visual functioning
L Language ( Aphasia)
E Executive functioning
Motor deficits (Apraxia)

43
Q

Difficulty in determining type of impairment?

A

Often not obvious what the deficit is as the neurological impairments can combine. Often the case that we mistake an attention problem for a memory problem.

44
Q

Assessment for deficit in attention

A

Trial making task- (dot to dot with numbers and letter)
Tests planning, focused attention, memory, visual neglect.
performing the test with a stop watch can highlight where the deficit is and how bad it is. Also if there are other impairments.

45
Q

Deficits in attention or arousal example

A

Easily distracted in conversation. Perform learned activities slower than before ( using DVD)

46
Q

Deficits in visual- perceptual functioning (agnosia) meaning

A

loss of ability to recognise objects, people, sounds, shapes, smells. Specific sense not faulty and no significant memory loss.
Key modality of information not providing enough information for person to recognise what they’re looking at.

47
Q

Assessment of visual perceptual functioning

A

Visual object and space perception test

48
Q

(Motor skills) apraxia definition

A

loss of ability to make familiar movements despite wanting to

49
Q

Executive functioning defecits

A

inability to complete higher order processes. (cant plan, problem solve, initiate or inhibit complex behaviour). Associated with prefrontal cortex.

50
Q

Assessment of executive functioning defecits

A

Category fluency task. look at nature of errors to determine problem in functioning and extent of issue. Whiteside 2015 (category fluency task associated with language function more than Executive functioning

51
Q

What is a test battery?

A

cluster of cognitive assessments which cover various bits of AMPLE. generates a single cognitive score

52
Q

Difficulties of diagnosing neurodegenerative disorders?

A

Symptoms of neurological deficits resemble those of psychopathologies (E.G. non epileptic seizures)
Neurological deficits associated with development of things like depression and anxiety
Other issues may play a part. e,g substance abuse

53
Q

Rehabilitation procedures

A

Exercises to improve impaired function (re-training)
Training in the use of cognitive and behavioural aids (substitution)
Assistive technology (compensation)
Basic drug treatment and psychotherapy to help deal with related mood disorders.

54
Q

Biological treatment types

A

Drug treatments (cholinesterase for Alzheimer’s) Levodpa (dopamine ) parkinsons.
Thrombolytic therapy dissolve blood clots
Deep brain stimulation (sending electrical impulses to certain parts of brain, used in Parkisnons
Surgery. chemotherapy, radiation (tumours. epilipsey)

55
Q

Cognitive rehabilitation

A

Basic training in areas of deficit

56
Q

cognitive rehabilitation for apraxia

A

Gestural training (Smania et al 2000).
replace tool with another tool. Visual feedback for monitoring

57
Q

Cognitive rehabilitation using virtual environment

A

Allows for a safe and controlled environment to help coordinate actions.

58
Q

Cognitive rehabilitation for executive functioning

A

Goal management training (GMT) break down components of task to small chunks. patient can slow down and check completion of each chunk separately.
Self instruction training (SIT) Ask patient to talk themselves through the problem (identify what point of task there on)

59
Q

General cognitive rehabilitation techniques

A

Emotional management, relaxation,

60
Q

Caregiver support programmes

A

Context of environment and stress of individual and collective individuals around them.
can be a cultural phenomenon (Muslims)

61
Q

Caregiver support programmes 2

A
  • Provide skills to help the carer with day-to-day living
  • Advice on how to modify the home environment (Gitlin et al., 2005)
  • How to control aggression and wandering (Pinkston et al., 1988)
  • Peer support groups are also an important means of maintaining Quality of life
  • Help caregivers and friends understand and respect individuals with neurological disorder.
62
Q

Alzheimer’s society advice for caregivers

A
  1. sufficient support
  2. Make time of day for themselves
  3. Understand their rights to local services
  4. Try to involve other family members in caregiving
  5. Look after their health
  6. Check whether entitled to financial benefits
  7. Confront and deal with feelings of guilt
  8. Take regular breaks
63
Q

Tips for making dementia sufferers feel better (INSIGHT)

A
  • Avoid situations they are bound to fail (humiliating), look for enjoyable easy tasks
  • Give plenty of encouragement (own pace, own way)
  • Do things with them not for them (independence)
  • Break activities into small steps so they feel a sense of achievement
  • Take pride in their appearance and compliment how they look. (self-respect)
64
Q

Important to note that the rehabilitation strategies are not independent and can be used in combination

A

Important to note that the rehabilitation strategies are not independent and can be used in combination

65
Q

Co production!!

A
  • is important to ensure a collaborative approach to individualise treatment to what best suits the patient.
  • More likely to use a compensatory system because he has had direct impact on its creation.
  • Psychosocial benefits (positive affirmation from friends/family due to creating a useful device for their needs) (Empowering patient) (similar to collaboration in CBT)
  • Important to consider what the patient values (Do they value one skill e.g. speech over another) It is important to consider what deficit to target. (similar to ABA)
