Amyotrophic side sclerosis is a frequent neurodegenerative disease related to a progressive degeneration of the two neurons in the voluntary driving way. It involves a paralysis of the limbs and labio-glosso-pharyngo-laryngo muscles which evolves in an unpredictable way, consequently generating a gradual impossibility to communicate. In order to compensate for this progressive disability, technical assistance to communication is offered to the patient throughout the evolution of his disease by several processes of recommendation and advice. At the same time, these processes involve quasi continual mourning and a waste of time. Consequently, how can successive recommendation of technical assistance be beneficial to a person while it regularly points out to her the constant aggravation of her disablement situation? Could technical assistance with evolutionary communication be a solution?
