How effective are Cat Scans in detecting clots, strokes, aneurysm's?

Hello, I'm a 21 year old student and recently been diagnosed with anxiety. I just been having strange feelings in my head, disorientation, fatigue, bad headaches, pressure headaches, body trembling, blurred vision, lethargy, ringing in ears, lack of concentration, head zaps or spasms that feel like my brain is floating freely in my skull, and worst of them all, sudden dizzy spells. Sometimes I'm shaking like a leaf and my body goes numb. I was told that that is a flight fright response that anxiety patients get when they go into shock, but I'm not convinced. I fear that I'm dying from a stroke, brain aneurysm, a blood clot or a stroke. Now mind you, I've never been in a car accident or had a had injury, but I'm EXTREMELY stressed and nervous on an everyday basis. I suffer from severe fatigue even after a good nights rest. This is very debilitating that I cannot even complete my studies or focus on school. I've had Cat Scans, and blood tests that came back normal, but I was told by a friend that those are not accurate in detecting much.  I spend hours crying and afraid I'll become a vegetable and my brain will just stop working one day. I've seen a psychiatrists once, but she didn't help much. She just told me to relax and it only helped for a few mins.

Thank you Dr Santos,

I made appointments with a neurologist to rule out anything abnormal, a cardiologist to rule out any heart rhythm issues or valve issues, and an endocrinologist to test for anything hormonal. Possibly in the future an ophthalmologists as well. I will posts on how that goes. Thank you.

Hi,
How are you? It is good that the initial diagnostic tests were fine.  According to a research by Perry et al published, the sensitivity of computed tomography overall for subarachnoid haemorrhage was 92.9% and  the specificity was 100%; while the negative predictive value was 99.4%  and the positive predictive value was 100%. These figures vary and may also depend on several factors. While the  symptoms may be associated with the diagnosis of anxiety, further evaluation may need to be done to rule out other possible causes. Seeking another doctor's opinion may also help. Take care and do keep us posted.
