23
Q

What are the imaging results of frontotemporal dementia?

A
CT/MRI = frontotemporal atrophy
SPECT = frontotemporal reduction in tracer uptake
24
Q

What is the dementia of lewy body dementia like?

A

Common early involvement of reduced attention, executive function and visuospatial skills

25
Q

What is needed to diagnose lewy body dementia?

A

Two of = visual hallucinations, fluctuating cognition, REM sleep behaviour disorder, positive DAT scan, parkinsonism (not >1 year prior to dementia onset)

26
Q

What are some features of the dementia that occurs in Parkinson’s disease?

A

80% have dementia after 15-20 years of Parkinson’s
Similar presentation to lewy body dementia
Positive DAT scan
Must have had parkinsonism for at least 1 year prior to dementia onset

27
Q

What imaging can be done for dementia?

A

CT, single photon emission CT, DAT scan, MRI

28
Q

What patients get a CT scan?

A

Standard investigation = useful for excluding tumour or bleed, quantifying vascular changes or identifying structural changes

29
Q

What patients get MRI scans?

A

Young patients, fast progression or other atypical features

30
Q

What type of dementia are SPECT scans best for?

A

Frontotemporal dementia

31
Q

When are DAT scans done?

A

Suspected lewy body or Parkinson’s dementia when patient doesn’t have enough supporting features to be sure of diagnosis

32
Q

What effect do cholinesterase inhibitors have?

A

Slow cognitive decline

33
Q

What types of dementia are cholinesterase inhibitors used for?

A

Alzheimer’s disease, lewy body dementia and dementia in Parkinson’s disease = less effective in treating Alzheimer’s

34
Q

What are the side effects of cholinesterase inhibitors?

A

Nausea and vomiting, headache, muscle cramps, worsen COPD and asthma
Bradycardia = check pulse before prescribing or increasing dose

35
Q

What are the contraindications of cholinesterase inhibitors?

A

Active peptic ulcer

Severe COPD or asthma

36
Q

What is memantine used for?

A

Licensed for Alzheimer’s disease = slows cognitive decline and prevents BPSD, start for moderate dementia

37
Q

What are the side effects of memantine?

A

Generally well tolerated = hypertension, sedation, dizziness, headache, constipation

38
Q

What professions make up the dementia MDT?

A

Doctors, nurses, PDS workers, support workers, OT, physiotherapists, dietician, speech and language therapy, psychology, social workers

39
Q

What role doe medical staff have in dementia?

A

Diagnosis, medical management, medication, mental health/capacity law

40
Q

What role do nursing staff have in dementia?

A

Mental health assessment and therapies

41
Q

What role do social workers have in dementia?

A

Care management, housing, adult protection, mental health/capacity law

42
Q

What people tend to become informal carers?

A

60% are spouses and 30% are adult children = provide 70% or more of total home care costs

43
Q

Why does dementia impose an objective burden on carers?

A

Leads to high levels of dependency and problematic behaviours

44
Q

What effect does being a carer have on people?

A

Increased psychological and physical morbidity, social isolation and financial burden

45
Q

What effect do psychological interventions for dementia have?

A

Have capacity to reduce carer distress and delay nursing home admission

46
Q

What implications does dementia have on driving?

A

Must be reported to DVLA = doctor decides if patient can drive while investigations are ongoing

47
Q

What paperwork must be filled in for a patient with dementia who drives?

A

Patient must fill in CGI form

Doctor fills out DVLA request form

48
Q

What happens as dementia progresses?

A

Behavioural and psychiatric aspects of dementia become more prominent = reduced ability to carry out normal activities independently

49
Q

What tends to cause the requirement of institutional care in dementia?

A

Loss of independence and BPSD

50
Q

What are some behavioural and psychological symptoms of dementia?

A

Hallucinations, delusions, insomnia, anxiety, disinhibition, agitation, aggression, depression

51
Q

What is the initial management of dementia?

A

Antecedents, behaviours and consequences = can use chart
Review physical symptoms and consider medication side effects
Consider comfort, environment and sleep hygiene

52
Q

What are some treatments for aggression?

A

Alzheimer’s = antipsychotics, citalopram, memantine, analgesia
Frontotemporal dementia = trazodone

53
Q

How are comorbid depression and anxiety treated?

A
Depression = antidepressant +/- adjuncts
Anxiety = antidepressants, benzodiazepines, pregabalin
54
Q

How are visual hallucinations and insomnia treated?

A
Hallucinations = cholinesterase inhibitors, antipsychotics
Insomnia = melatonin, Z drugs, benzodiazepines, sedating antidepressants
55
Q

How is aggression treated?

A

Benzodiazepines, antipsychotics, sedating antidepressants, cholinesterase inhibitors, memantine, pregabalin
