My husband had a tia a few months ago. Has had tests for his heart, ct scan, mri scan. Very high cholesterol levels so takes statins. Heart seems fine, however he occasionally freezes - for a minute or 2 he is unable to move at all. I witnessed one of these episodes before the tia, but he had had a couple since. He is unwilling to see a doctor. Could this be linked to the tia or something else?
