Jack, here is a link to one site that describes Brain Congestion as:
Brain, Congestion of 417? (2nd)

Dunglison: (Cephalaemia) Accumulation of blood in the
vessels of the brain

I hope this is helpful.
I found an old funeral home record book that described a man's death as "Suicided. He slit his throat 3 times, one cut ear to ear, nearly severing his head"
I have laughed at that visual many times, the first cut and it's resulting ouchie, and I would have put the knife down!
