Q

What cognitive assesments can you do for a patient in hopsital with suspected dementia?

A

ACE-III gold standard
AMT-10
6-CIT
MOCA
MMSE

Generally patients in hospital are difficult to assess so ask GP to see in 6-8 weeks when illness has settled and refer to memory clinic

Q

How would you describe dementia to a patient in clinic OR OSCE?

A

Umbrella term for damage to the brain. What causes the damage determines what type of dementia it is

Cannot get diagnosis from CT, can only get post-mortem by taking a brain sample, however CT can show patterns that point towards one disease process over the other

It is irreversible but we can do XYZ to support

We can also refer you to the.. (e.g OT, physio, social services) who can help you with these things

Assess carer strain

Q

Alzheimer’s disease is the most common cause of dementia. How does it present?

A

Insidious onset with slow progression. Behavioural problems are common. Diagnosed on clinical history but brain imaging may show disproportionate hippocampal atrophy.

Q

What are the microscopic pathological changes in Alzheimer’s disease?

A

cortical plaques due to the deposition of type A-beta-amyloid protein and intraneuronal neurofibrillary tangles caused by abnormal aggregation of the tau protein

Q

What non-pharmacological treatment options does NICE recommend in the management of Alzheimer’s disease?

A

group cognitive stimulation therapy for patients with mild and moderate dementia,
group reminiscence therapy,
cognitive rehabilitation

17
Q

Outline the pharmacological management of Alzheimer’s disease

A

1st line for mild - moderate disease : donepezil, galantamine and rivastigmine (all ACh inhibitors)

2nd line for severe disease / where 1st line is contraindicated: memantine (an NMDA receptor antagonist)

18
Q

When is donepezil (acetycholinesterase inhibtor used in Alzheimer’s disease) contraindicated?

A

bradycardia

19
Q

Vascular dementia is the 2nd most common cause of dementia. Give its key features

A

Suggested by vascular risk factors e.g. hypertension. Imaging is suggestive of vascular disease. Often has a step wise progression.

20
Q

What is the prevalence of vascular dementia?

A

20% of dementia cases are vascular

21
Q

How do you manage vascular dementia?

A

lifestyle modification

medication to reduce cardiovascular risk e.g. statins and anti-hypertensives

22
Q

How does frontotemporal dementia typically present?

A

Onset often early e.g. in a younger person with fam hx

often associated with complex behavioural problems, language dysfunction may occur

23
Q

What are the macroscopic changes seen in frontotemporal dementia?

A

Atrophy of the frontal and temporal lobes

24
Q

Which type of dementia is associated with MND?

A

frontotemporal

25
Q

How does Lewy-Body dementia typically present?

A

Dementia, visual or auditory hallucinations, delusions and Parkinsonism

Fluctuating cognition

26
Q

What is the prevalence of Lewy Body dementia?

A

10-15% of dementia cases

27
Q

What are the risk factors for Lewy body dementia?

A

increasing age,
Parkinson’s disease.
REM sleep behaviour disorder

28
Q

Outline the management of Lewy body dementia

A

promote exercise,
cognitive training,
cholinesterase inhibitors,
may benefit from levodopa introduced at low doses and increased slowly

29
Q

What are the important differentials of dementia?

A

Pseudodementia- depression
Delirium
SOL
Hypothyroidism
Addison’s
B12/folate/thiamine deficiency

30
Q

What is defined as young onset dementia?

A

Diagnosis under the age of 65

31
Q

What investigations should you carry out if you suspect young onset dementia?

A

Cognition assessment
Baseline blood tests,
Neuroradiology,
OT functional assessment,
Genetic testing,
CSF testing to assess for Alzheimer’s

32
Q

what are the autonomic features of dementia?

A

orthostatic dizziness,
syncope,
falls,
urinary tract symptoms,
constipation

33
Q

What is BPSD?

A

Behavioural and psychological sxs of dementia e.g. agitation, aggression, mood disturbance, hallucinations

34
Q

How can BPSD be managed?

A

Identify triggers
Engage in meaningful activities
Sleep hygeine
Watch and wait - if no improvement after 4 weeks consider risperidone
