Conditions

Cognitive Dysfunction, Neuroimaging, Posterior Reversible Encephalopathy Syndrome

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.

Interventions

BIOLOGICALneuroimaging examination,neuro-cognitive test,blood pressure,blood sample

neuroimaging will be perform,neuro-cognitive will be tested,blood pressure will be monitored,blood samples will be tested

MeasureTime frameDescription
level of LDL in bloodwithin 10 years after deliverhyperlipidemia:LDL\>3.12mmol/L
neuroimaging examinationwithin 10 years after deliverthe 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 Mini-mental State Examinationwithin 10 years after deliverthe scores of Mini-mental State Examination,normal (27-30);mild (21-26); moderate (10-20); severe (0-9).
neuro-cognitive test of Montreal Cognitive Assessmentwithin 10 years after deliverthe scores of Montreal Cognitive Assessment,normal (≥26); abnormal (\<26).
blood pressure and hypertensionwithin 10 years after deliverHypertension: blood pressure ≥140/90 mmHg
level of lactate dehydrogenase(LDH)within 10 years after deliverinflammatory: LDH\>380U/L
