[Toe phasic posture reflex: description and distribution among patients with neurological disease and in the general population].

A clinical sign is described consisting of a brief extension of the toes after upward tapping of the plantar surface of their terminal phalanges. Electrological data support the hypothesis of a long loop reflex, which we call the "toe phasic posture reflex" (TPPR). In a preliminary study, this sign was observed in patients with central nervous system disease, especially in subcortical brain disorders regardless of etiology.

[Normal pressure hydrocephalus in an elderly patient].

Introduction: Idiopathic normal pressure hydrocephalus is a disease that most frequently concerns subjects of an advanced age. It is not easy to establish a definitive diagnosis, and the practitioner frequently encounters decision-making problems regarding the following question: should a shunt be performed, or not? Opinions remain contradictory, even though the available scientific data is increasingly precise. The aim of this review is to analyze the physiopathogenic, clinical, paraclinical and therapeutic data associated with this type of hydrocephalus.
