Head pressing

Head pressing is a veterinary condition characterized by pressing the head against a wall or pushing the face into a corner for no apparent reason.[1] This condition is seen in dogs, cats, cows, horses, and goats. Head pressing is usually a sign of a neurological disorder, especially of the forebrain (e.g., prosencephalon disease),[1] or of toxicity due to liver damage, such as portosystemic shunt and hepatic encephalopathy.[2]

For the human practice of affection, see Touching heads.

It should be distinguished from bunting, which is a normal behavior found in healthy animals.

Possible causes
  • Prosencephalon disease
  • Liver shunt
  • Brain tumor
  • Metabolic disorder (e.g., hyponatremia or hyperatremia)
  • Stroke
  • Infection of the nervous system (rabies, parasites, bacterial, viral or fungal infection)
  • Head trauma[3]

Liver neurotoxicity

A liver shunt is a congenital or acquired condition that may lead to toxicity and head pressing. Additional symptoms include drooling and slow maturation early in development. Middle-aged and older animals more commonly suffer from liver cirrhosis than younger animals.[4]

Viral causes

Several viruses that cause encephalitis or meningoencephalitis can lead to the neurological sign of head pressing, such as eastern equine encephalitis and bovine herpesvirus 5.[5][6]

gollark: Yes, spidertron exists now?
