Cyberpsychosis

Cyberpsychosis is a mental illness, specifically a dissociative disorder, caused by an overload of cybernetic augmentations to the body.

Background

Those afflicted with cyberpsychosis are known as cyberpsychos, those who have existing psychopathic tendencies, enhanced by cybernetics, and as a result have lost their sense of identity as a person, either to themselves or others. They come to view regular people and other living things as weak and inferior. With their enhanced physical abilities and complete disregard for life, cyberpsychos are extremely dangerous to anyone that crosses their path. Cyberpsychosis can affect anyone modified with cybernetics eventually, but the less empathetic or psychologically stable a person is, the more susceptible they are to it. There is no real cure, though treatment is available. The effects are cumulative. A single cyber hand is unlikely to cause cyberpsychosis, but replacement of all four limbs and both eyes will probably start down the slippery slope to madness. Cyberpsychosis symptoms are gradual, ranging from decay of self-preservation, distancing or disregard from friends and family, and poor or impulsive outbursts or acts. They start to identify more with machines than people, and stop doing things that used to give them pleasure (eating, sleeping, socializing, sex, etc). Eventually human interactions become irritating, and then irritation morphs into contempt, and finally violence. Not all cyberpsychos are physically violent. Some have fragmented personalities, some are kleptomaniacs, others are compulsive liars. But violence towards living things, especially people, is most common.
Cyberpsychosis has become a major problem in the technology-saturated world of Cyberpunk. It is actually quite common in many boostergangs, though fairly rare in polite society. Police departments have heavily armed and armored units, called psycho squads, who specialize in subduing or killing cyberpsychos.
Incidentally the government (and corporations) are not going to wait for you to go over the edge. It is quite common for governments or corporations (who are often the de-facto government) to track people who are known to install lots of cyberware. This is another reason ripperdocs exist; not everyone wants to be on a government watch list for cyberpsychosis.
