Questions
What is the possible diagnosis?
How would you manage this?
What are the management options for behavior and psychological aspect of dementia in this patient?
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5472076/
referring to the same article, TD can persist after withdrawal of meds — possibly due to antipsychotic or anti depressant.
using alternative agent such as clozapine for BPSD may reverse TD— but this runs the risk of marrow suppression. others include propranolol, clonazepam (potentially inappropriate meds)
The symptoms may suggest tardive dyskinesia. Antipsychotics have been ceased since March 2023, and other potential medication that may cause this is SSRI. I think it's worth trying to deprescribe SSRI and try to optimise non pharmacological and patient-centered approach for BPSD.
The movements may be voluntary or involuntary.
Voluntary repetitive movements can occur as part of the dementia symptomatology or just as a tic. In which case nothing really helps apart from distraction.
Such gross involuntary movements could be due to dystonia, tardive dyskinesia or choreoathetosis which could be due to drugs, cerebrovascular disease or neurodegeneration.
Citalopram has been known to cause involuntary movements (case report), while one case of donepezil and athetosis has also been reported.
This article actually teases out drugs which may cause TD: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5472076/
Rather than start something straight away, the thing to do is perhaps deprescribe and try non-pharmacological tricks such as distraction. My geriatrics approach would be stop as many drugs as you can, and…
Is there any analysis out there that ranks antipsychotics and its stroke risk?
This gentleman is probably having antipsychotic induced tardive dyskinesia. Prompt withdrawal of antipsychotics will be helpful.
Given the sensitivity to antipsychotics and visual hallucinations, Lewy body dementia is something worth considering. MRI brain would be helpful in this case.
As for the non cognitive symptoms of dementia, it would be good to explore the unmet needs with involvement of multidisciplinary team. Visual assessment would be great.
Unless his symptoms are potentially harmful to himself or to others, use of antipsychotics should be avoided.
