Objectives:
The objective of this study was to review software errors known as single event upsets (SEUs) or bit flips due to cosmic rays in epilepsy neurostimulators.
Materials and methods:
A case report of a single event upset or bit flip is discussed; device manufacturers and publicly available data were queried for both incidence and types of error as well as strategies of software error mitigation.
Results:
Neurostimulators, like other implanted devices such as pacemakers, are prone to single event upsets. Strategies for SEU mitigation are reviewed.
Conclusions:
Cosmic radiation can threaten RAM and settings of neurostimulators; neuromodulation teams and device designers need to take this threat into account when designing multifunctional neuromodulation systems.
