If not a stroke as mri states, what cd be the cause of sudden immobility of left arm and leg and speech impediment ,left side of face is droopy. tnks?

Possible TIA?: Sudden weakness/paralysis of one side of the body along with speech difficulty would usually indicate a stroke if the symptoms persisted for many hours or a day. In this case the MRI should indicate brain damage(infarction). If the neurological symptoms resolved within a day or so, and a MRI was done afterward and was normal, it would indicate a Transient Ischemic Attack. SEE www.bit.ly/1qu6w2M
