Old Peoples Care Flashcards
What are the effects of normal aging?
Difficulty finding words
Forgetting things and events
Not being able to remember the name of an acquaintance.
Family not worried about the memory.
Not remembering conversations which occurred > 1yr ago.
Dementia is different because of the affect on ADL.
What is dementia?
Syndrome caused by many brain disorders, leading to decline in cognitive functioning, memory AND activities of daily living (ADL).
Always progressive.
Likely to have clear consciousness.
What are the RF for developing dementia?
Ageing Genetics Mild cognitive impairment Parkinson's Cerebrovascular Cardiovascular Smoking DM Lack of exercise Obesity
How does a Px with dementia present?
1) Cognitive impairment relating to disturbance of higher cortical function, memory, thinking, judgement, planning, language, perception and visuospatial awareness. Px usually have a clear consciousness.
2) Psychiatric or behavioural disturbances: changes in personality, emotional control, and social behaviour; depression, agitation, hallucinations, and delusions.
3) Difficulties with ADL.
Need to have this presentation for >/= 6 months for a diagnosis.
What are the stages of dementia?
1) Early stage-
Forgetfulness and other memory symptoms. Usually short term memory affected i.e. lunch, shopping list, keys.
May get subtle mood changes and behaviour i.e. loss of motivation/interest
May be minimal intrusion day-day.
2) Mid stage-
More prominent memory problems
areas of cognition; visuospatial awareness, language. Higher order functioning i.e. sequencing, planning.
More prominent behavioural problems
More obvious problems with disabilities.
May lose insight, can downplay severity of their condition.
3) Severe- Global problems in all cognitive domains. Can't recognise family members. Severe disabilities- falling etc Requiring 24hr care
What are the common causes of dementia?
> 65yrs old- 2/3 is Alzheimer’s, the second most common is vascular.
<65yrs old- 1/3 Alzheimer’s (still most common), VD, alcohol, LB dementia, FTD.
What are the common subtypes of dementia?
Alzheimer’s
Vascular
LBD
FTD
What are the causes of Alzheimer’s disease?
Sporadic
Genetic
Increased risk with Downs syndrome
What are the features of Alzheimer’s disease?
Gradual onset and slow progression.
Presents early with memory impairment.
Mood and behavioural changes may be minimal but pre-existing anxiety may worsen.
On imaging see reduced volume in temporal lobe and posterior cingulate.
Macroscopic- cortex and hypothalamus atrophy.
Microscopic- tau tangles and amyloid plaques.
How is Alzheimer’s disease managed?
Non pharm- Tailored activities for pts Pharm- Acetylcholine-esterase inhibitors (donepezil, galantamine and rivastigmine) for mild to moderate. NMDA antagonists (memantine) of contraindicated, as add-on therapy in moderate or as monotherapy in severe Alzheimer’s.
Only use antipsychotics if at risk of self harm.
What is vascular dementia?
Stepwise deterioration in cognitive function by different mechanisms including ischaemia/haemorrhage secondary to cerebrovascular disease.
Imaging will show signs of infarct, bleeds, WM ischaemia.
What are the features of vascular dementia?
Progression speed varies. Emotional disturbance Gait disturbance Speech disturbance Memory disturbance Difficulty with attention and concentration Seizures Visual disturbances, sensory or motor symptoms
How is vascular dementia managed?
Treat symptoms and reduce cognitive decline
Manage challenging behaviours
Music/art therapy
Pharmacological interventions are not really useful.
What is Lewy Body dementia?
Lewy bodies in the substantia nigra, paralimbic and neocortical areas.
What are features of Lewy Body dementia?
Loss of memory, function and cognition early on.
Followed by Parkinsonism
Visual Hallucinations
Fluctuating episodes may be confused with delirium initially.
How is Lewy Body dementia managed?
Manage same as Alzheimer’s
AChE inhibitors and NMDA antagonists
Avoid neuroleptics in Lewy body dementia as very sensitive and can lead to irreversible Parkinsonism
Also consider rivastigmine in Parkinson’s disease.
What is frontotemporal dementia?
<65yrs
Insidious onset
Change in personality i.e. impulsivity (XS spending, sexual disinhibition, overeating, obsessions), loss of empathy, apathy (loss of interest), lack of insight.
Intact memory and visuospatial awareness
Gradual onset but may progress quickly in younger Px.
Imaging will show frontotemporal atrophy.
How is frontotemporal dementia managed?
NICE say do not treat with AChE inhibitors or NMDA antagonists.
How is dementia initially diagnosed?
Memory clinic with an MDT allows for a holistic approach in diagnosis. Includes OT, psychiatrist, community mental health professionals social, pharmacists etc.
Dementia is a clinical diagnosis made through personal and collateral Hx.
Important to talk to the Px initially alone.
Examinations include GPCOG, AMT, MMSE, 6-CIT, MOCA etc.
Must inquire about the Px functionality/impairment of ADL.
Also must ask about the risks i.e. risk to self (self harm, suicide, neglect, driving), risk to others (BPSD [Behavioral and psychological symptoms of dementia], driving), risk from others (vulnerability).
Important to explain interventions to promote cognition, independence and wellbeing. As well as discussing pharmacological interventions.
Diagnose first as dementia then subtype it.
Basic ADL- Essential for living i.e. eating/drinking, washing, dressing etc
Instrumental ADL- More difficult
If BPSD can have regular follow ups in the clinic.
What are the benefits of diagnosing dementia?
Relief from having a diagnosis. Optimising medical management Maximising decision making autonomy Access to care and services Risk reduction (driving) Clinical cost effectiveness A human right to know your own diagnosis
How is dementia investigated?
It rarely exists on its own and may be overlooked by diagnostic over shadowing.
Need to ensure that an underlying diagnosis is not missed; FBC, U+Es, LFTs, B12/folate, Ca, glucose, TFTs.
Confirm diagnosis with blood culture, CXR, MRI and psychometric tests.
CSF if considering CJD
Brain imaging- structural with CT, functional with dopamine, glucose metabolism.
EEG
How is all dementia managed non-pharmacologically?
Inform Px of their diagnosis and prognosis.
Provide psychological support to give positive outlook on life and allow engagement.
Early discussions to allow advance planning, i.e. regarding lasting power of attorney, preferred care plans etc.
Carer support
Px must inform the DVLA about their diagnosis.
Non-cognitive therapy involves music, dancing, art,, aromatherapy etc.
Px should be looked after in the community, but admitted if their own safety or the safety of others is at risk.
Palliative care in the cases of end stage. PEG is not really shown to have any added benefit so should not be used.
How can dementia be prevented?
1) Diet- Healthy and balanced can be preventative for dementia, i.e. CV RF will increase risk of developing vascular dementia.
2) Exercise- Large amount of CO goes to brain so exercise will help perfuse the brain.
3) Social interaction
4) Cognitive stimulation- Learning new skills, brain teasers.
What is BPSD?
Behavioural and psychological symptoms of dementia.
These are the presentations in the more later stages of dementia
Presenting with delusions, hallucinations, agitation, emotional lability, depression, anxiety, apathy, social or sexual disinhibition, motor disturbance (for example wandering or repetitive activity), and sleep disruption.
Increased care costs and prognosis. Very challenging, can impact individual cognitive of life. 4 main clusters; Affective Psychotic Hyperactive hk
