80-year-old Patient Was Injected With Brain Magnetic Resonance Study Findings

80-year-old patient was injected with brain magnetic resonance study findings are as follows: Research revealed ischemic leukoencephalopathy. Cortical atrophy. I wonder if this kind of treatment the patient was diagnosed 80 years and if you can be patient and thinking suddenly lose consciousness or die suddenly or will the treatment extent the life? Thank you for your sensitiveness.
