Is it possible to have hypoxic brain injuries due to syncopal episodes (presumed to be secondary to orthostatic hypotension and/or PSVT) producing muscle weakness? Is so would there be any changes on a MRI scan?

Brief Answer:
Syncopal attacks would not cause muscle weakness

Detailed Answer:

Normally syncopal attacks are transient & do not cause hypoxic injury to brain ,at least not enough to cause muscle weakness. Syncopal episodes may cause hypoxic brain injury only if recurrent or associated with some seizure episode / persistent hypotension during attacks.

MRI brain is usually normal in hypoxia; but few patients show grey white matter disturbances.

Hope I have answered your query. Let me know if you need clarifications.
