dementia Flashcards
what is dementia
- umbrella term for a group of cognitive symptoms including memory loss, difficulties with language, thinking, reasoning and problem solving. These symptoms are caused by several different progressive brain diseases.
what are the progressive brain diseases following dementia
Alzheimer’s disease,
vascular dementia,
Dementia with Lewy bodies fronto-temporal dementia
posterior cortical atrophy
what is alzhemiers
- most common kind of dementia and accounts for approximately 60% of all dementias.
- Early AD is associated with difficulty remembering recent events, difficulty finding words, finding it difficult to know where you are.
what is vascular dementia
- Vascular dementia is the second most common type of dementia.
- caused by damage to the blood supply of the brain; either blood leaks on its way to brain cells or is blocked from reaching cells.
- effects depend on what part of brain is affected
what is mixed dementia
- Mixed dementia is a term used to describe people who have both Alzheimer’s disease and vascular dementia.
what is dementia with lewy bodies
- 10% of ppl with dementia
- one of its defining characteristics is fluctuating awareness and alertness.
- symptoms include visual impairment, mostly mistakes in interpretation of visual information and hallucinations.
- similar symptoms with Parkinson’s (tremor and muscle stiffness)
- memory loss is less evident
whats fronto-temporal dementia
- 2% of dementia cases
- predominantly affects people under the age of 65 years.
- frontal and temporal lobe affected
- changes in personality, behaviour and language.
- difficulties with language
3% of cause of dementia, for example:
Creutzfeldt-Jakob disease, a rare brain disorder
Huntington’s disease, an inherited, progressive brain disease
why is early diagnosis of dementia important
- knowing the type of dementia the person has can help you to better understand why the person is doing what they do, what retained abilities they have and why they have difficulty doing some things.
- help the person understand the symptoms that they are experiencing
- allow for access to advice and support
- allow access to treatments that can slow down the progression of the condition
- provide an opportunity to prepare for the future and plan ahead
Dementia is a progressive condition. This means that the symptoms associated with dementia will get worse over time.
Depression is characterised by feelings of low mood which go on for a while.
Symptoms of depression can be similar to those of dementia, such as forgetfulness and having difficulty making decisions.
Depression can occur alongside dementia and is treatable
Delirium is a temporary, short-term state of confusion. It has a range of causes, most commonly infection (e.g. urinary or respiratory), drug side-effects or dehydration.
Delirium can occur alongside dementia and is treatable.
what are 6 psychological needs that those with dementia will feel more intensely
- comfort
- identity
- attachment
- occupation
- inclusion
- love
As people lose the ability to communicate verbally, it can be even more difficult to communicate these distressing emotions other than through their behaviour. As such, it is even more important that we seek to understand a person’s non-verbal communication.
what are some of the well known consequences of caring for a loved one with dementia
- exhaustion
- role changes
- changes in relationship
- social isolation
- loneliness
Things that help people to live as well as possible with dementia include:
Companionship
A sense of belonging
Being out in the world (Trevor)
Being social (listen to Trevor talk about how he enjoys the singing group)
Having help to continue doing things you always did
Feeling valued
Recognising that dementia is not the end (Wendy describes her attitude)
Having a chance to contribute (Sue)
Feeling understood
People living with advanced dementia are at particular risk of being socially excluded
whats a rights based approach to dementia care
A rights-based approach ensures good quality care and support which respects people’s human rights including the right to privacy, family life and liberty, and to be treated with dignity, throughout the journey of living with dementia regardless of where we live or receive care and support.
in which law states: it is legally binding that people with dementia and their family carers are treated with dignity, and receive care and support that is based on individual need.
equality act of 2010
what are the 9 protected characteristics in the equality act
- race
- sexual orientation
- religion
- age
- disability
- gender reassignment
- marriage
- pregnancy
This rights-based approach to the care of people with dementia is promoted by:
World Health Organization
Alzheimer’s Disease International
Alzheimer Europe
Alzheimer’s Society
Dementia Alliance International
The Alzheimer’s Society includes the following in their campaign to ensure the human rights of people affected by dementia.
End discrimination because of reduced mental capacity.
End age discrimination towards older people.
End age discrimination towards younger people.
Improved support for people from black, Asian and minority ethnic (BAME) communities.
Improved care and support.
Robust action on abuse.
Fairer care funding.
Continued action on inappropriate prescription of antipsychotic drugs.
As dementia progresses eating and drinking can become more difficult for people living with dementia. This may be due to the reduced ability to smell and see.
Dementia can change how flavours are recognised. Taste and sense of smell change naturally with the ageing process.
As dementia progresses, eating and drinking preferences and habits may change. As a result many people can become at risk of malnutrition and dehydration.
A central focus in person-centred care is finding out and adopting the person’s perspective, to empathise and see the world through their eyes. This is especially necessary when the person is distressed.
how is advanced care planning used to help meet the needs of dementia patients
Advance care planning is an approach to making sure that a person’s wishes, needs and preferences for care are known, recorded and acted upon.
Care providers have a central role to play in communicating with people living with dementia and their families.
Personality is one of many factors that influence a person’s experience of living with dementia; other factors include physical health, life history, brain disease, the nature and quality of interactions and relationships that the person has.
what are some barriers that can prevent a dementia patient from seeking help
stigma: A person may be afraid of negative reactions from family, friends and neighbours or concerned that they will be treated differently, be less valued and experience discrimination in health and social care
lack of insight: A person may lack insight or awareness into the severity of the changes they are experiencing
cultural differences: A person may come from a cultural or ethnic background which attributes these changes to something other than brain disease, such as a failing in past life or some kind of retribution for a moral affront
ignorance: A person may perceive the changes to be a normal part of changing and/or associated with other ongoing health problems
apprehension: A person may feel apprehensive about engaging with healthcare professionals and services
prior experiences: A person may have prior experiences of family members with dementia who did not receive high quality care
denial: A person may not wish to confront the changes they are experiencing and may rather deny what is happening
Professional barriers
Many general practitioners are aware of the stigma surrounding dementia and are reluctant to assign a person with dementia this label.
A UK study [3] (read details regarding the reference) indicated that the perceptions of the stigma associated with dementia affected the degree to which practitioners communicated with patients about their dementia. Some practitioners described dementia as being ‘in a different awful reality’ due to ‘loss of self, power and cognitive functions’ and ‘worse than death’.
Another study showed that GPs think people with dementia often struggle to understand what their diagnosis means.
One approach to supporting primary care practitioners is to emphasise the importance and increasing availability of post-diagnostic support services for people living with dementia [4] (read details regarding the reference).
Family barriers
Different members of the family may have different perspectives on the changes the person is experiencing.
For example, a daughter may be adamant that her mother should go to the doctor to undergo an assessment, while her father sees no need and says that they are managing fine.

What 2 questions need to be addressed when diagnosing dementia
- Are the person’s symptoms consistent with a progressive brain disease?
- If so, which type of progressive brain disease is most likely to be causing these symptoms?
where would the assessment process for dementia diagnosis take place
GP or memory clinic
what typically goes on during the assessment process of dementia diagnosis
a medical and personal history about the symptoms the person is experiencing
a physical examination (including blood tests) to rule out other conditions which may cause changes
cognitive assessment (including tests of recent memory, spatial awareness, abstract reasoning)
assessment of mood (as depression can lead to changes in cognition)
Less commonly the person may have a brain scan.
According to the Memory Services National Accreditation Programme [5] (read details regarding the reference), memory assessment services must ensure that?..
- the person understands the process:
- appropriate consent is gained
- the person is involved in decision making:
- the person is consulted about the diagnosis:
what are 7 things that are analysed in multi-dimensional history for a diagnosis of dementia
- life history
- family context
- current and prior medical conditions
- history of changes in cognition and or behaviour
- risks
- mental health issues
- personality
what 5 blood tests are undertaken abiding by NICE for dementia diagnosis?
- routine blood tests including full blood count
- biochemistry tests (for example, calcium, glucose, renal and liver function)
- thyroid function tests
serum vitamin B12 and folate levels - mid-stream urine test (if delirium is a possibility)
what are the cognitive changes found in a dementia patient under the table of 4 A’s?
- amnesia
- aphasia
- agnosia
- apraxia
define amnesia
difficulty in recalling certain details from memory.
define agnosia
difficulty in recognising the things around us, for example, objects, faces, shapes, smells.
define apraxia
difficulty in performing certain tasks or movements.
When exploring a person’s cognitive symptoms, ask about:
amnesia
aphasia
agnosia
apraxia
attention and concentration
what are 2 validated measures of depression?
geriatric depression scale
patient health questionnaire
what is the geriatric depression scale
tool used to identify depression in older adults
- Choose the best answer for how you felt over the past week:
are you basically satisfied with your life?
do you feel like your life is empty?
do you prefer to stay at home rather than going out and doing things?
do you feel you have more problems with memory than most people?
what is the patient health questionnaire
tool used to screen and diagnose selected mental health disorders, for example, depression, anxiety, alcohol, eating and somatoform disorders.
- Over the last 2 weeks, how often have you been bothered by any of the following:
trouble falling or staying asleep, or sleeping too much?
trouble concentrating on things such as reading the newspaper or watching television?
feeling tired or having little energy?
how is brain imaging helpful when dealing with dementia
- provide information about changes in different parts of the brain. This can help in identifying which type of underlying brain disease (dementia) a person may have.
- help with identifying other reasons (e.g. brain tumour) why a person is experiencing changes in cognition and behaviour.
what 4 types of brain scan might be undergone for a dementia patient
- Computerised axial tomography (CAT) scans use x-rays to take pictures of the brain.
- Magnetic resonance imaging (MRI) scans use radio signals to create an image of the brain.
- Single photon emission computerised tomography (SPECT) scans look at how blood flows through the brain.
- Electroencephalograms detect and record electrical activity patterns and check for abnormalities.
It is important to diagnose young-onset dementia early so that people can discuss the possible effect on their lives and plan their future [5] (read details regarding the reference).
NICE recommends that people with suspected young-onset dementia should be referred to specialist services for diagnosis and support [6
what is 2 major issues are associated with dementia in ethnic minorities.
- they presume memory loss is normal aging
- Another issue is that services are often not culturally appropriate and adaptation is required to meet the cultural needs. This could range from availability of translators to using materials which are culturally relevant.
Research suggests that people from minority ethnic groups are less likely to present to primary care with memory problems and more likely to fail to attend for appointments in the memory service [7] (read details regarding the reference).
during dementia diagnosis, what type of information should be verbally and physically given to patients + family?
- the type of dementia and how it may progress
- which health and social care professionals will be involved in supporting them and how to reach them
- how dementia affects driving
their legal rights and entitlements
their right to reasonable adjustment if they want to work - sources of support (for example, local support groups, online forum, charities, financial and legal advice services, advocacy services)
after dementia diagnosis, what type of support should given to patients + family?
receive access to a memory service (or an equivalent hospital or primary care-based multidisciplinary dementia service) offering a choice of flexible access or pre-arranged appointments to monitor well-being.
Alzheimer’s disease: starts slowly with difficulties involving short-term memory and word-finding.
Vascular dementia: caused by disruptions to the blood supply to the brain.
Dementia with Lewy bodies: shares a number of similarities with Parkinson’s disease.
Frontotemporal dementia: associated with behavioural changes as well as memory issues.

- even if cups empty, doesnt mean they have durnk enough
- facilitate drinking to promote e.g coloured cup or infused fruit
4 key things to know about oral health with dementia patients
- can be issue if help is rejected or they forget to brush
- changes in diet/taste.salivary flow and syrup based medication = increased risk of oral disease
- carer can be used to help oral health or encourage them to look after their oral health
- person with dementia should be given the chance to make decisions about their dental treatment
4 key things to know about social engagement
- social engagement reduced agitation and disorientation
- different activity interests for each dementia patients
- not everyone likes to meet in same way or do same things or for same period of time

People living with dementia may experience stress. Such stress might be related to:
adjusting to loss
having to get used to changes in relationships with family and friends
having symptoms of dementia
having to find new ways to do things
having to find new ways to cope with a situation [11]
4 key things to know about exercise for dementia patient

- improves self esteem and reduces anxiety and depression
- helps retain daily living skills
- helps dementia patient rest and sleep at right times
It is possible to reduce the risk of falls through:
making sure to clean up spills
organising furniture in a way which minimises people being at risk of bumping into it
increasing lighting where possible
wearing clothes which do not trail on the floor
minimising the use of medications which affect eyesight and balance
wearing shoes that fit well
The Alzheimer’s Society suggest 10 ways to make dressing easier for people living with dementia:
Label the wardrobe and drawers so the person knows where things are – or have glass doors so the person can see where things are in the wardrobe.
Lay clothes out for a person.
Reduce the number of options.
Give the person enough time.
Accept whatever their choice is even if it unusual.
Use photos of the person (perhaps provided by family) so you know how they used like to dress.
Suggest the person has layers of clothes – easy to adjust when temperature fluctuates.
Change clothes regularly.
Make sure the dressing room is comfortable.
Go shopping with the person.

- respiratory infection
- diabetes
- congestive eheart failure
- dehydration
