Mike, my husband's a long term GBM survivor,... over four years since a successful resection of a 2 1/2 x 7 cm , tumor... right temporal lobe. MGMT methylated. He had radiation and two six month rounds of temodar, an MRI every 2 months. Had successful surgery for recurrence a year ago. He didn't have radiation this time but taking temodar again... new tests showed MGMT methylation for a second time. It's been a year! I've been trying to figure out why he's begun to have symptoms from a new, slightly weakened left side. It shows mostly in his slow walking, dragging his left foot. He's almost fallen many times... over sidewalk cracks or going up the stairs. I hold onto him. He's lost his balance a couple of times... "tipping" over while standing, looking straight ahead. He's had two MRI's in two months. a full spinal MRI, PET CT scan, and lumbar puncture. I thought it might be hydrocephalus but nothing shows on spinal tap, or... MRIs... all clear. That's good!!... but why the dragging foot... balance problems? not knowing the whys... I've done all the reading, asked all the questions I can think of. A physical therapist's just started coming by with exercises... he's getting used to using a cane, his hand grip's ok. It's difficult leaving him alone, so afraid he'll fall. So lucky not having issues until now, but here we are... Does anyone have foot dragging issues without tumor growth showing on MRI.s? He's not taking steroids... just temodar and anti nausea... Thank you!
