The strong relationship between falling and severity of cognitive impairment in the elderly is well established. The association premorbid gait and executive disorders suggests that they are under tension by the same mechanisms. The gait fortiori neurological are fall risk factors. Dysfunctions underlying disorders as Parkinson called march executive disorders are subcortical origin involving so the basal ganglia. This study is indeed based on the assumption that the dysfunction of the basal ganglia as observed in parkinsonian syndromes resulting in disorders of posture and walking, by dysexecutive syndrome, anxiety and the contrast vision disorders. These gait exposed to falls and dysexecutive these disorders with cognitive impairment and greater susceptibility to confusional states. The executive disorders, gait disorders, anxiety, disturbances of vision and especially saccadic eye movements, impaired vision contrasts are well established in the degenerative parkinsonian syndromes. This study proposes a new approach to assessing gait disorders to define a high risk of falling in the presence of parkinsonian walking in the elderly over 75 years.
