Q

Facts about Alzhemiers Disease

A

Most common cause of dementia.
In Alzheimer’s disease, connections between these cells are lost.
Due to protein build up forming abnormal structures called ‘plaques’ and ‘tangles’
Eventually nerve cells die and brain tissue is lost.
Progressive disease

Q

Explain Dementia with Lewy body

A

Canbe diagnosed wrongly and is oftenmistaken for Alzheimer’s disease.
Lewy bodies are tiny depositsof a protein (alpha-synuclein) that appear in nervecells in the brain.
Not fully understood why cause dementia but believed
low levels of important chemicals (mainlyacetylcholine and dopamine) that carry messagesbetween nerve cells
a loss of connections between nerve cells, whichthen die.

Q

What is Frontotemporal Dementia?

A

It is sometimes called Pick’s disease or frontal lobe dementia.
Refers to the lobes of the brain that are damaged in this type of dementia.
Changes in personality and behaviour, and difficulties with language.
Significant cause of dementia in younger people
Linked to clumps of abnormal proteins inside the cells, including proteins called tau and TDP-43

Q

Facts about consent when diagnosing Dementia

A

Person must have the proposed action explained to them and have the mental capacity to make an informed decision.
Establish that a person lacks mental capacity:
Have ‘an impairment of, or a disturbance in the functioning of, the mind or brain’ which may affect their ability to make a specific decision and
Because of this be unable to:
Understand the relevant information and the consequences of deciding against a treatment or intervention and,
Retain the information long enough to consider it and come to a decision and,
Make the decision without pressure from anyone else and,
Communicate the decision

16
Q

Facts about diagnosis of Dementia

A

Access to a memory service or equivalent hospital- or primary-care-based multidisciplinary dementia service.
Should offer a choice of flexible access or prescheduled monitoring appointments.
When people living with dementia or their carers have a primary care appointment, assess for any emerging dementia-related needs and ask them if they need any more support.
Provide people living with dementia with a single named health or social care professional who is responsible for coordinating their care

17
Q

State the support a named healthcare professional to offer those living with Dementia

A

Named professionals should:
Arrange an initial assessment of the person’s needs, which should be face to face if possible
Provide information about available services and how to access them
Involve the person’s family members or carers in support and decision-making
Give special consideration to the views of people who do not have capacity to make decisions about their care, in line with the principles of the Mental Capacity Act 2005.
Ensure that people are aware of their rights to and the availability of local advocacy services, and if appropriate to the immediate situation an independent mental capacity advocate

18
Q

State Interventions to Promote Cognition in Dementia Patients

A

Offer group cognitive stimulation therapy to people living with mild to moderate dementia.
Consider group reminiscence therapy for people living with mild to moderate dementia.
Consider cognitive rehabilitation or occupational therapy to support functional ability in people living with mild to moderate dementia.
Do not offer acupuncture to treat dementia
Do not offer ginseng, vitamin E supplements, or herbal formulations to treat dementia

19
Q

State when memantine can be used as monotherapy in dementia management

A

moderate dementia and are intolerant/contra-indication to others
Severe AD

20
Q

State the treatment for vascular dementia

A

Only consider AChE inhibitors or memantine for people with vascular dementia if they have suspected comorbid Alzheimer’s disease, Parkinson’s disease dementia or dementia with Lewy bodies.
Need to manage cardiovascular conditions such as hypertension and high cholesterol

21
Q

state the treatment for Dementia with Lewy body

A

Offer donepezil or rivastigmine to people with mild/moderate/severe dementia.
Only consider galantamine if donepezil or rivastigmine not tolerated.
Consider memantine if other AChE inhibitors not tolerated/contra-indicated

22
Q

State how to treat frontotemporal Dementia

A

There is no pharmacological treatment for now
Do not offer AChE inhibitors or memantine to people with frontotemporal dementia.

23
Q

State the mode of action of AChE Inhibitors

A

Acetylcholinesterase removes Acetylcholine which is released from neurones into 2 inactive fragments.
If acetylcholinesterase activity is inhibited, acetylcholine availability at its receptors is increased.
Small improvement in cognitive function

24
Q

List the cholinergic side effects of ACHEI

A

nausea, abdominal cramps, fatigue, sleep disturbances and agitation

25
Q

State the mode of action of NMDA Antagonists

A

Neurotransmitter – Glutamate
Attaches to NMDA receptors - activated- Ca2+ influx.
In Alzheimer’s Disease you have too much glutamate
Too much calcium speeds up nerve damage.
So,
Memantine acts as a competitive ‘NMDA antagonist’ thus reducing Ca2+entry into the cells

26
Q

Some commonly prescribed medicines are associated with increased anticholinergic burden, and therefore cognitive impairment. True/false?

A

True

27
Q

List two examples of medication that can increase cholinergic burden

A

olanzapine
Amitripyline

28
Q

List the Behavioural and Psychological Symptoms of dementia (BPSD)

A

Agitation, aggression, hoarding, wandering, hallucinations, sexual disinhibition, delusions, apathy and shouting

29
Q

List the possible clinical cause of BPSD in DEMENTIA

A

pain, constipation, infection (such as delirium) or dehydration

30
Q

List the environmental causes of BPSD in Dementia

A

changes in surrounding environment, inappropriate care, disrupted routine, noise or discomfort

31
Q

State the first line treatment for the non cognitive symptoms of Dementia

A

Music therapy, aromatherapy, physical exercise if able, dance, hand massage, social interaction and stimulation, reminiscence or therapeutic touch

Changes to environment: can they find the toilet-? Pictorial toilet signs, identity any trip hazards/ remove clutter, room temperature, is their light?

32
Q

According to NICE guidelines, when should an antipsychotic be used in the treatment of BPSD in Dementia?

A

only offer an antipsychotic if the patient is at ‘risk of harming themselves or others’ or ‘experiencing agitation, hallucinations or delusions that are causing them severe distress’: LAST RESORT!

33
Q

The only licensed antipsychotic in BPSD is…..

A

Risperidone

34
Q

Facts about the administration of Risperidone

A

Lowest effective dose
Shortest period of time
Review clinical need at least every 6 weeks
Increased risk of stroke
Discontinue if the client is not getting any benefit
To be prescribed alongside non-pharmacological interventions

35
Q

Do not offer ……… medication for BPSD

A

Valproate

36
Q

Facts about Risperidone

A

Atypical antipsychotic

BNF: ‘Short-term treatment (up to 6 weeks) of persistent aggression in patients with moderate to severe Alzheimer’s dementia unresponsive to non-pharmacological interventions and when there is a risk of harm to self or others’.

Short-term intervention
Dosage: 250mcg BD-can be increased by 250mcg BD on alternate days
Usual dose: 500mcg BD (max. 1mg BD)
Formulations: tablet, orodispersible tablet and a oral solution

37
Q

State the side effects of risperidone

A

postural hypotension, extra pyramidal side effect (akathisia and parkinsonism) and drowsiness

38
Q

State the role of the pharmacy team in dementia

A

Prescribing: NMP memory clinic
Clinical interventions: treatment recommendations (such as: advising on the management of complex case or alterative formulations)
Counselling
Supporting carers
Signposting
Dementia Friends/ Champion: https://www.dementiafriends.org.uk/

Q

List examples of hospital intervention in dementia

A
