Long-term Consequences of Neuroimaging and Perceived Cognitive Dysfunction in oPRES

• Conditions: Cognitive Dysfunction; Posterior Reversible Encephalopathy Syndrome; Neuroimaging
• Interventions: Biological: neuroimaging examination,neuro-cognitive test,blood pressure,blood sample

• Registration Number: NCT05140850
• Lead Sponsor: Dunjin Chen

Brief Summary

The purpose of this study is to explore the long-term consequences of neuroimaging and perceived cognitive dysfunction in obstetrics posterior reversible encephalopathy syndrome.

Detailed Description

This is a prospective study. The investigators divided the PE or E patients into two groups, namely PRES group and non-PRES group, according to diagnostic criteria . The general information（demographic data，blood pressure.etc.）and blood sample will be collected. Additionally,all patients receive neuroimaging examination（DTI,ASL,3D-TMI.etc.）and neuro-cognitive test（MMSE,MOCA,CFQ, etc.） to assess the cerebral white matter lesions and cognitive changes.

Arm && Interventions

Group	Intervention	Description
PRES group	neuroimaging examination,neuro-cognitive test,blood pressure,blood sample	PE or E with PRES
non-PRES group	neuroimaging examination,neuro-cognitive test,blood pressure,blood sample	PE or E without PRES

Primary Outcome Measures

Name	Time	Method
neuroimaging examination	within 10 years after deliver	the degree of white matter lesions(0,normal; 1, limited cortical or subcortical white matter oedema; 2, white matter oedema \> cortical oedema, white matter oedema extending into deep white matter; 3, white matter oedema \> cortex oedema, oedema extending to the ventricular surface; 4, the involved regions substantially extend to the ventricular surface and are almost completely confluent; 5, involved regions are fully confluent and continuous, ventricular deformity due to the oedema).The value of fractional anisotropy(FA) in PRES group may higher than non- PRES group, and mean diffusivity (MD) in PRES group may lower than non- PRES group.
neuro-cognitive test of Montreal Cognitive Assessment	within 10 years after deliver	the scores of Montreal Cognitive Assessment,normal (≥26); abnormal (\<26).
level of lactate dehydrogenase(LDH)	within 10 years after deliver	inflammatory: LDH\>380U/L
neuro-cognitive test of Mini-mental State Examination	within 10 years after deliver	the scores of Mini-mental State Examination,normal (27-30);mild (21-26); moderate (10-20); severe (0-9).
blood pressure and hypertension	within 10 years after deliver	Hypertension: blood pressure ≥140/90 mmHg
level of LDL in blood	within 10 years after deliver	hyperlipidemia：LDL\>3.12mmol/L
