Loss of Information Associated with the Perceptomotor Cognitive Domain: Praxis

We have proposed a random walk model to model perceptomotor cognitive domain damage in patients with neurocognitive disorders(NDs). The random walk model with truncated Lorentz memory profile. We have reported that memory damage has an impact onrandom walkers' praxis and, consequently, on the global diffusive process, fractal dimension and information loss, and it is themajor impact on information loss. We have found two diffusive regimes: the ordinary and the superdiffusive. We have observedtwo superdiffusion regions separated by a region with ordinary diffusion regime: one in the anti-persistence region and one in thepersistence region. These regions are characterized by diffusion level curves, invariant curves of scale variations in the Lorentzdistribution. In the anti-persistence region, we found a greater variation in entropy, for example, greater loss of praxis-relatedinformation than in the persistence region. Therefore, when memory impairment is accompanied by observation of anti-persistentbehavior, there are greater losses of information related to the perceptomotor domain of random walkers.
