Can PRES be permanent?
In conclusion, this report reveals that PRES can occur after delivery without the symptoms of preeclampsia or eclampsia and cause permanent encephalomalacia.
Can you recover from PRES?
Prognosis. With adequate treatment, 70-90% of people with PRES make a full recovery within hours to days. 8–17% of people with PRES die, although this is not always a direct consequence of the PRES. Of those who have residual symptoms after PRES, this is attributable largely to hemorrhage.
Is PRES syndrome serious?
Prognosis and outcomes. PRES usually has a favourable prognosis among pregnant women, with resolution being rapid and complete after adequate therapy. Permanent damage can persist in a few cases (6%) and death due to haemorrhage has been described in a couple of patients.
Can PRES be cured?
There is no direct treatment for PRES, other than removing or treating any underlying cause. For instance, immunosuppressive medication may need to be withheld. 40% of all people with PRES are unwell enough to require intensive care unit admission for close observation and treatment of complications.
