My brother had a stroke 4 years ago with right side paralysis and now he has recovered but still his speech is not clear and cannot pronounce words. Also he has difficulty understanding and has memory loss. Also he has lots of pain in his left hands and legs.
His recent CT scan of the brain shows this "Old ischemic changes in left temporo parieto-occipital lobe with changes of encephalomalacia and surrounding gliosis, Sequal of old ischemic insult"
I want to know how serious is this and if left untreated will this progress as he gets older and is this life threatening. What all damage to his body this can cause as I have read online that Encephalomalacia cannot be cured and has dangerous consequences. So I am very worried. Any clear explanation is highly appreciated.
