Q

what is the meaning of ‘phantom boarder’ syndrome, and what is it a feature of?

A

delusion where the patient believes that their house is inhabitated by unwelcome guests

feature of late onset schizophrenia

17
Q

what are some practice points we need to consider if we had to prescribe psychotropic medications for affective disorders in geriatric patients?

A
  • have all the non-pharmacological approaches/measures been exhausted?
  • what other drugs is this patient on that may potentially interfere with this medication?
  • what is the renal function of this patient?
  • what is the lowest effective dose for the shortest amount of time- start low go slow
  • organise medication review in at most 3 months
18
Q

why might it be difficult to distinguish thought disorder in psychogeriatric patients?

A

geriatric patients may have cognitive impairment which may affect communication/language abilities. The only way we assess thought disorder is through speech and language.

19
Q

what is the number one cause of psychosis in late life?

A

dementia

20
Q

what are some characteristics of late onset schizophrenia?

A

premorbid long history of suspiciousness/isolation/difficulties in relationships

delusions are usually persecutory; partition delusions; phantom boarder syndrome

deafness and visual impairment is often associated

very poor insight

females >males

Hallucinations in more than one modality (e.g. olfactory/somatic)
–> greater than 45 yrs old

21
Q

what does partition delusions?

A

patients have a delusion that other people are trying into get into their house

22
Q

how might we distinguish late onset schizophrenia or early onset schizophrenia?

A

Usually late onset schizophrenia patients do NOT present with thought disorder, and hence if you have a geriatric patient with thought disorder you should be thinking of early onset schizophrenia that has not been diagnosed.

Think late onset schizophrenia if there are partition delusions

23
Q

can we distinguish between very late onset schizophrenia and dementia associated with psychosis?

A

not really…. It is really hard to tell the difference

24
Q

how might we treat late onset schizophrenia?

A

psychotic medications are not that great in elderly patients due to SE and reduced efficacy, drug interactions etc

So really mainstay treatment is establishing a therapeutic relationship with them and risk assessment and risk management!! –> refer for psychogeriatric assessment

the threshold for admitted patients with late onset schizophrenia is quite high.

optimise other medical comorbidities, provide family/carer support, discuss legal issues e.g. EPOA and disability support

Environmental modifications, address visual/hearing impairments

25
Q

what anti-psychotics can we use in BPSD?

A

risperidone/olanzapine first line

quetiapine is another option

26
Q

what are some complications of old age schizophrenia?

A 
increased risk of tardive dyskinesia
risk of isolation, poverty, self neglect
increased risk of suicide
poor management of medical comorbidities
polypharmacy
harm to others
increased risk of substance abuse
