Hello,
I don't know if it is a good idea to include "nAGQ=5 orother points" in the
options script!
If you only use a unique random effect you can try to the AGQ method.

glmer(InInt~speciality+position+stkperyr+conf+age+years+risk+stroke_type+(1|pid),data=dord4mod,nAGQ=5,family=binomial,verbose=TRUE)

Best wishes,

Martí
