Degenerative Feedback Anomaly

Degenerative Feedback Anomaly (or DFA) was a condition which caused near-blinding headaches for sufferers when attempting to use a Neurohelmet. Though rare in 3062 since the advent of better neuro-circuitry technology, it was an impairment which still arose in individuals with neurological damage, such as from head trauma.

A notable sufferer was Tamas Rubinsky, who acquired DFA as a side-effect of being exposed to the Wei nerve agent, UrbStryc-A Nerve Gas.
