1866 All Year Round 10 Feb. 104/2 As for any other travellers, not my immediate companions, whom I may touch upon, do you set them down as mere brain-worms, abstractions, and creatures of the imagination.

1884 A. J. H. Duganne Injuresoul 70 And still each dying brain-worm weaves, With leaves of books for mulberry leaves; And brain-worms crawl from mind to mind, And still their silken shrouds they wind.

2007 O. Sacks Musicophilia (2008) v. 45 Such music is designed, in the terms of the music industry, to ‘hook’ the listener,..to bore its way, like an earwig, into the ear or mind; hence the term ‘earworms’—though one might be inclined to call them ‘brainworms’ instead.

2. Zoology and Veterinary Medicine. Any of various parasitic worms that infect the brains of mammals or other vertebrates; esp. any nematode of the genera Elaphostrongylus and Parelaphostrongylus (family Protostrongylidae), which parasitize the central nervous system and certain other tissues of deer. Also (without article): worms of this kind.

1805 J. Lawrence Gen. Treat. Cattle 586 Even the famous Guinea-worm..turns out to be of the same family of those of which I am speaking, that is, of ideal or brain-worms.

1870 Proc. Zool. Soc. 849 Not a single specimen [of Planer's Lamprey] examined was exempt from these brain-worms.

1895 Hutchinson (Kansas) Daily News 29 Aug. 2/3 Among the former [sc. internal parasites of sheep] are the liver fluke (Fasciola hepatica)..,brain worms (Cænerus cerebralia),..and several other entozoa.

1962 Daily News-Record (Harrisonburg, Va.) 18 Jan. 3/3 Marshall says that brain worms were first discovered in the south-east in deer in Arkansas in 1959.

1994 Equinox Jan.–Feb. 48/1 Also hunting moose is a parasitic brainworm that causes fatal neurological damage.

2007 E. Hebert New Hampsh. Patterns 64/2 Back in the 1970s, moose were rare, and the one that jaywalked Main Street in my home town was likely a wanderer from the North infected with the brain worm.

3. Zoology. A liver fluke, Dicrocoelium dendriticum (family Dicrocoelidae), which parasitizes many species of mammal (and occasionally humans), and has a cercarial stage which enters the brain of an intermediate host, the ant, resulting in behavioural changes conducive to transmission to mammals; (also) the individual cercaria that infects the brain of an ant.

1969 Amer. Midland Naturalist 82 606 The German workers gave this metacercaria the name ‘Hirnwurm’ or brainworm because of its localization.

1977 Behav. Ecol. & Sociobiol. 2 421 The brain worm changes the behavior of the ant, causing it to spend large amounts of time fastened by its mandibles onto the tips of grass blades, a location that obviously facilitates being eaten by livestock.

1991 Amer. Naturalist 138 867 The most famous example [of favorization] is probably that of the brain worm (the trematode Dicrocoelium dendriticum), which provokes aberrant behavior in infected ants and makes them available for ingestion by grazing sheep.

2006 D. C. Dennett Breaking the Spell i. 3 This little brain worm is driving the ant into position to benefit its progeny, not the ant's.
