[|Human|] hi My younger brother who is now 28 years old had met with an accident in 2003. He did not have an external injury. But left side of the head or brain was hit. also has a clot somewhere in brain. He was unconscious for 1 month. There after not able to walk or do anything. Then after 2 years of physiotherapy of all body parts and all he was physically ok. But still his right hand and right leg has some problems. then after all the therapies still he used to forget things easily and get angry very fast and very frequently. older memories were still intact. Now after 11 years again we did the MRI of brain and it s findings are 1)small old infarct in left ganglio capsular region 2) Right antral polyp seen. What does that indicate and also what should be the treatment.
[|AI|]  Hello dear, Please accept my concerns for your brother. It appears that your brother suffered some brain injury, during that trauma episode following which he remained unconscious for a month. The details of that brain injury can be best known with a brain imaging(like magnetic resonance imaging-MRI) of that event only. Present residual weakness on right side, can be explained well with the old gangliocapsular infarct, presently seen in brain imaging. It might have resulted due to effects of head injury, for mechanisms not precisely known. Best thing at present is to screen your brother for young onset hypertension, efficient physiotherapy and discuss starting antiplatelet and statin group of medicines. You need to discuss this with your neurologist. Need any further information, you are welcome.
