Meseekna is a simulation gaming engine formulated in the early 1970s as an experimental tool for measuring cognitive impairment after traumatic brain injuries. It was aggressively developed for application throughout medicine, from measuring the cognitive impact of substance abuse to the early detection of Alzheimer’s Disease. Meseekna has been continually validated, refined, and tested by individuals and teams across government, industry, and civil society. It has grown into one of the most reliable cognitive assessment and human development tools available. We customize integrated real-time simulations and training programs for teams of all sizes and recently launched our first consumer gameplay.
