    Body Heat and Brain Dysfunction

    What possible disorders or diseases could cause sensitivity to elevated external temperatures? The subject, when exposed to temperatures greater than roughly 75 degrees Fahrenheit reacts the way most people do at temperatures of 90 or higher. After short periods of exposure to high heat, generally between 15 and 45 minutes, the subject begins to feel slightly faint, light-headed, and a feeling of being suffocated. He becomes slightly disoriented, irritable, and sweats copiously. He becomes fatigued easily and cannot maintain his focus readily.

    The subject is a 21 year old male, no drug, alcohol, or tobacco use. The only pre-existing medical conditions are asthma (Controlled), ADD, and a leg length discrepancy that prevents standing for periods longer than roughly 25-30 minutes. The subject is not currently taking any medications and is adequately hydrated. His diet is poor but not seriously so, but the symptoms dont seem to be effected by the quality of his diet. These symptoms have been present for as long as he can remember but have grown much more pronounced in the previous several years.

    The subject works as a welder and is exposed to corresponding occupational hazards but nothing that would potentially cause such heat sensitivity.

    Now, what, if any, are the disorders and diseases of the brain that could possibly cause an extremely low tolerance for high heat? I would appreciate anything you could give, I dont care how long or short the list is

    Too many things can cause heat intolerance, many are not directly related to the brain at all.

    I'm heat intolerant because I don't sweat properly, have low blood volume, low blood pressure, and easily dehydrate (even though I drink plenty of water). If I get too warm I get dizzy, can lose my ability to see for short periods, and even faint - due to falling blood pressure.

    Obvious things to check would be thyroid, blood sugar, sweating ability, and if the person becomes easy dehydrated.

    Re: Body Heat and Brain Dysfunction

    the hypothalamus in the brain and the spinothalamic tract within the spinal cord are what really govern body temps. i lost my ability to actually sweat at all on my right side from spinal cord damage,this of course was the tract damage. i also cannot feel the difference between hot and cold on that side either,yet i retained evenlight sensitivity to touch there and can feel everything else but hot or cold there,with the exception of pain coming from the outside in? very insane let me tell ya.

    is there a particular reason you are looking at the brain for this diagnosis or are you just assuming it would be a brain issue? like the above poster mentioned,there can be many different reasons for what you have described with symptoms. its a matter of testing certain things and ruling them out. it can take awhile,but this would really be the only way to truely Dx the reason for his reactions to heat. has he seen his primary for a full physical which would also include some bloodwork? that would tbe the best starting point in looking for the reasons/Dx. please keep us posted on anything you find out.
