Michigan Mom Survives Sudden Brain Aneurysm Linked to Congenital AVM, Faces Long Rehab
A healthy 42-year-old Michigan mom, Nichole Vallette, woke with a thunderclap headache and nausea and then suffered a ruptured brain aneurysm caused by a congenital arteriovenous malformation (AVM). She underwent emergency brain surgery, remained in ICU, and is now in rehabilitation, gradually regaining movement and speech. AVMs are congenital and often undetected until rupture; recovery varies widely, with many survivors facing lasting deficits. Her family stays hopeful and plans to bring her home as she continues extensive rehab, a process that could take months to over a year.
