Abstract:
Computer-aided processing of the results obtained with the intrathecal infusion test using our newly developed mathematical model simplifies the investigation technique and thus the diagnosis of normal pressure hydrocephalus. Simultaneous determination of resistance and compliance in a single session markedly reduces the examination-related stress on the patient. In contrast to the classical methods, the new calculation does not require the ICP to reach a plateau. Unlike the static approach, our model describes the functional pressure-dependent course of the resistance. This means that account is taken of the non-linearity of the CSF dynamics during the processing of the biosignal. The intrathecal infusion test used to measure resistance and compliance is a reliable diagnostic method in patients with a normal pressure hydrocephalus.
