Abstract

New investigate methods have extended the scientific and clinical knowledge of the circulation of the cerebrospinal fluid (CSF). Methods of measurement of resistance to CSF outflow have improved during the last 15 years (Børgesen et al. 1978; Ekstedt 1978; Shapiro et al. 1984; Kosteljanetz 1987; Gjerris et al. 1989 a). A thorough knowledge of the dynamic equilibrium between CSF production and absorption is essential for the understanding of the changes in the intracranial space during pathological conditions. CSF dynamics comprehend all factors concerning formation, flow rate, direction, and absorption of CSF.
