Q

What is the definition of polypharmacy?

A

A single patient taking 5 or more medications daily

17
Q

What drugs should be avoided in Parkinson’s patients?

A

Atypical antipsychotics

18
Q

What drugs should be avoided in Lewy body dementia?

A

Antipsychotics

19
Q

Name a acetycholinesterase inhibitor?

A

Donepezil

Rivastigmine

Galantamine

20
Q

Name a NMDA antagonist?

21
Q

When are oral antibiotics used on a pressure ulcer?

A

Only when there are signs of infection

22
Q

What is seen on an MRI for Alzeimer’s disease?

A

Widespread cerebral atrophy mainly involivng the cortex and hippocampus

23
Q

What does raised intracranial pressure show on CT?

A

Effacement of the cerebral ventricle and loss of grey-white matter differentation

24
Q

What is seen on CT with frontotemporal dementia?

A

Frontal lobe atrophy

25
What does a focal hyperdense lesion in the occipital region mean on CT?
Characteristic of a brain tumour within the occipital lesion
26
What are the features of Lewy body dementia?
1. **Progressive cognitive impairment** * in contrast to Alzheimer's, early impairments in attention and executive function rather than just memory loss * cognition may be fluctuating, in contrast to other forms of dementia * usually develops before parkinsonism 2. **Parkinsonism** 3. **Visual hallucinations** (other features such as delusions and non-visual hallucinations may also be seen)
27
What are the investigations for Lewy body dementia?
1. **Usually clinical** 2. **Single-photon emission computed tomography (SPECT)** is increasingly used. It is currently commercially known as a DaTscan. Dopaminergic iodine-123-radiolabelled 2-carbomethoxy-3-(4-iodophenyl)-N-(3-fluoropropyl) nortropane (123-I FP-CIT) is used as the radioisotope. The sensitivity of SPECT in diagnosing Lewy body dementia is around 90% with a specificity of 100%
28
What is the management of Lewy body dementia?
1. **Both acetylcholinesterase inhibitors** (e.g. donepezil, rivastigmine) and memantine can be used as they are in Alzheimer's. NICE have made detailed recommendations about what drugs to use at what stages. Please see the link for more details 2. **Neuroleptics** should be **avoided** in Lewy body dementia as patients are extremely sensitive and may develop irreversible parkinsonism. Questions may give a history of a patient who has deteriorated following the introduction of an antipsychotic agent
29
What is the mechanism of haloperidol?
Dopamine antagonist
30
What medication may be given instead of halopeidol for parkinson's patients?
Lorazepam
31
What are the key features of a history for lewy body dementia?
1. Flutuating cognitive function in contrast to other forms of dementia 2. Visual hallucinations 3. Parkinsonism
32
Which class of medications should be withdrawn in patients with dementia? Why?
Tricylic antidepressants Due to worsening of cognitive impairment
33
What are the first line drugs for alzheimer's?
1. Acetylcholinesterase inhibitors * Donepezil * Galantamine * Rivastigmine
34
What is the second line drug for alzheimer's?
Memantine
35
What medication causes blurry vision, nausea, and falls?
Digoxin
36
What factors favour frontotemporal dementia over bipolar affective disorder?
1. Presents later in life 2. Social disinhibition 3. Family history
37
When is Lewy body dementia favoured over parkinson's?
1. Cognitive symptoms started before motor
