Should a I go for an MRI even though my CT Scan was clear?
For the past 3-4 months I have been getting this werid foggy head. It all started when we found out my brother had a brain disorder which he did surgery on (Cavernous Malformation) I started getting left sided numbness, headaches and weakness. My left eye would swell also. I got scared, went to the doctor and did a blood test and CT SCAN. both came back normal but I find that I still feel the same. Do you think a CT Scan can miss it?

It's true that an MRI is superior to CT for a brain scan in most cases; one exception where CT is preferred is with a fresh head injury. That doesn't necessarily mean that the CT was inadequate, though, just that MRI tends to give a little better resolution. MRI also has the benefit of not exposing your brain to radiation. So, you could get a referral with an actual neurologist to see if additional testing is warranted and could discuss whether it may be worth it to have an MRI done. They may do additional blood work, too. They may want to rule out infectious causes, etc.
As a side note, a person's lifestyle or mood status can also cause one to be foggy headed. For example, just being inconsistent with your sleep/wake times can lead to this. Or, not getting sunlight and instead sitting for 8 hours playing video games. Just giving a couple examples. So please be attentive to your lifestyle and diet while exploring medical causes with your doctor.
