Yes, there is mention of higher risk with some neurological situations. I’ve found a decent guide here from the Association of British Neurologists.
The link to the original web site is here in case this document is replaced and the PDF link above starts not to work.
A lot of it seems to be related to breathing and swallowing impairments, bulbar function or certain drugs used to treat (for example) epilepsy or immune response. Rather than me try to summarise what is in there, I can only suggest people have a read.
I hope this is helpful.
Very best wishes all,
Richard
