Patient's Query

Hello doctor,

If the stroke has occurred in the left side of the brain, we know the patient's right side of the body would be weak and numb. But when the patient's right side of the face is also numb, is this also because of the stroke on the left side of the brain?

Hello,

Welcome to icliniq.com. Strokes on the left side of the brain will cause weakness in the right side of the body and right facial weakness. Please let me know if you have any other questions.

Patient's Query

Thank you doctor,

I would like to add that I had a vascular ultrasound and I am trying to understand which artery would be stenotic. The internal carotid artery (ICA) feeds the brain. So I am confused about the face numbness. Please help.

Hello,

Welcome back to icliniq.com. The middle cerebral artery branch of ICA (internal carotid artery) can cause cortical and subcortical strokes leading to hemibody and hemifacial numbness involving the somatosensory cortex in the parietal cortex. Also, the posterior cerebral artery supplying the left thalamus can cause pure sensory stroke in the right hemibody and hemiface.

Same symptoms don't mean you have the same problem. Consult a doctor now!
