Q. What is discreet hypodensity on the right occipital in the brain? Why does it occur and how to treat it?

A.  The occipital lobes form the rear ends of the two major halves of the brain - the cerebral hemispheres. They are principally concerned with our ability to see and interpret what we see. A discreet hypodensity is what someone studying a computerised tomographic (CT) scan of the brain might observe in a patient. It refers to a small, well-defined area in the brain that is less dense in appearance than the surrounding tissue. The causes are many and can vary from damage produced by a lack of blood supply to that part of the brain to a lump in the brain. Treatment will depend on the cause of the abnormality. Such an abnormality should be evaluated by a consultant neurologist or neurosurgeon. You are advised to seek such help and guidance.
