Clinical Trial Summary

Hydrocephalus is characterized by excessive accumulation of cerebrospinal fluid (CSF) in the ventricles of the brain. One of the forms of hydrocephalus is called "normal pressure", although one of the main signs is precisely an alteration of the intracranial pressure (ICP), it is here called active hydrocephalus (HA). Although MRI is the reference radiological modality for the characterization of HA. The Evan's and DESH index are radiological diagnostic criteria based on the dilation and morphology of the CSF compartments. These morphological indices remain insensitive and specific. In recent years, advances in Phase Contrast (MRI-PC) and Diffusion (MRI-DTI) MRI have generated new biomarkers of brain viability. The aim of this study is to characterize by MRI the impact of hydrocephalus on brain fluids and tissues.

Inclusion Criteria:

• For Patients with hydrocephalus:

• Age > 55,

• Ventricular dilation: Evans Index > 0.3;

• Patients with cognitive impairment, and gait disturbances and/or urinary incontinence or a combination of these three symptoms;

• Absence of other neurological diseases that could cause ventriculomegaly, information and non-opposition.

• For Controls:

• Age = 55;

• No ventricular dilation: Evans Index < 0.3;

• Individuals who have no neurological or psychiatric disease;

• No neurological deficit.

• No history of neurosurgery or head trauma;

• signed informed consent;

Related Conditions & MeSH terms

• Cerebrospinal Fluid
• Hydrocephalus

Intervention

Other:
• MRI
During management, patients with hydrocephalus will be subjected to flow MRI and diffusion MRI. Flow parameters and diffusion parameters will be measured and compared to those found in control subjects receiving the same type of imaging
