So you have a headache tension-type - How do you feel this diagnosis? It is likely that almost a throw away line and immediately dismissed as nothing to fear - only with your life! But in my experience often headaches "tension-type, although usually less severe than migraine is more upset with the constancy of it, unable to move, you start down. One wonders whether it would be preferable to have severe pain for a day and then be free of pain for a period of time! 150 years ago, mainly due to the pulsating nature of headaches, it was assumed that the main problem was (expansion or dilation) of blood vessels - and any headache that was / is the nature of pain has been diagnosed as nonpulsatile migraine were excluded from a diagnosis of migraine - the idea of a tension headache developed because despite the lack of evidence, the cause of the throbbing headache is considered muscle (scalp and forehead) and / or stress, another hypothesis has been! However, a historical study (1) of the 1970s showed that: - the tension in the muscles of the scalp and forehead in people suffering from headaches during a headache is unlike the group without pain head - the people who suffer from headaches, tension has increased (and more) the tension in the muscles of the neck compared with those without headache - which could indicate that tension headache is a search headacheOther cervical unknown ( 2) showed that tension-type headache was significantly reduced after rehabilitation of the muscles of the neck i. e. treat the neck, providing more evidence that tension headache is really a puzzle with its origin in the neck. A significant body of recent research has shown that awareness or hyper excitability of the brainstem is the primary disorder in people who suffer from headache, tension-type (this is also the case of migraine - support the idea that tension headache and migraine are not separated, but the conditions are different expressions of the same condition) ... and that consciousness is present continuously i. e. even when the headache off power - confused? In addition, the triptans, a drug developed specifically for migraine, are also effective in eliminating tension headache. But ... "does not work triptans" by reducing the dilation of blood vessels? Well first thought ( and took a great extent) to be the case, but experiments have shown that triptans decrease awareness of the brainstem. Now, what is this thing called the "trunk". The brainstem is an area in the upper spinal cord, which receives data (activity) of the internal structures of the head (including blood vessels), and the structures of the upper neck (ligaments, joints and their capsules and muscles), which are provided by the first three spinal nerves. The brain stem is also influenced by serotonin and a system called diffuse noxious inhibitory control - Do not be overwhelmed by these words - I'll explain this in another place. Now all the information or activity in relation to pain headache, headaches and migraines, passes through the brain stem to higher brain centers where it is interpreted, where decisions are made! The brainstem is a headache that the black box is in the plane - is final common pathway for all migraine headaches and information. The question remains what is the awareness. As I said before the brain stem is influenced by four sets. The serotonin system and the diffuse noxious system inhibitory control (DNIC) act to inhibit or desensitize the brain stem - if the other system is not working satisfactorily, then the brain stem is hyper sensitive and excitable. I'm sure you've heard of serotonin and its role in the head. Serotonin is a neurotransmitter and its role is to act as a filter, removing minimal risk or not (pain) signals. Under normal circumstances, serotonin levels satisfactory to counteract pain signals. However, the levels of serotonin in people with pain heads are often too low. Research has shown a clear relationship. During the injection of a drug that reduces serotonin, the test subjects have headaches. Similarly, when they were injected with serotonin, headaches were relieved - so it may be that the brainstem is sensitive to the optimal levels of serotonin, or diffuse noxious inhibitory control system (DNIC) is poorly understood. This mechanism involves a reduction in awareness of pain when the pain is felt while in the rest of the body. For example, headaches or migraines is perceived as much, much less severe after hitting his thumb with a hammer! If DNIC is insufficient, it would be like hitting your thumb with a hammer, much less, and your headache is only slightly less severe. Maybe so, awareness of the brainstem may be secondary to a disorder of the DNIC. However, research results have been quite inconsistent, a landmark study (3) demonstrated that it is unlikely in patients with migraine. In addition, other research has shown that DNIC plays a lesser role in women ... and gender, women are more susceptible to headaches, making less likely to DNIC be affected, or disclosure or hyperexcitability of the brainstem may also occur as a result of abnormal signals in the course of injury or a dangerous disease of the upper structure of the neck, including the joints, muscles and ligaments, or awareness could also result from a similar position ie messages in an abnormal condition of a structure within the head, for example, an infected tooth, sinus disease (true sinus headache is rare), irritation of the meninges ... However, the results of the landmark study conducted at the end of 1970 (1) and more recently (2) suggest that the most likely source of consciousness is in the neck. My clinical experience supports these massive results. Evidence led to the abandonment of the muscles of the forehead and scalp as the cause of tension headache pain and now focuses on "What is the awareness of the brainstem? ... ... Why is it so difficult, with so many resources when it is so obvious - the reason is that the role of the neck does not correspond to the medical model of headaches and migraines, and therefore the model has shown little interest to explore this possibility. It is essential that all factors have the potential to sensitize the brain stem, a survey also. At present this is not the case - the neck is largely unknown. Stay tuned ...!
