The stellate ganglion is a bundle of nerves in the neck. Nearly a century ago, researchers discovered that an injection to reduce signals from these nerves could have remarkable positive effects for patients suffering from severe neck pain or headaches. A Stellate Ganglion Block Injection in Las Vegas also has been found useful for patients diagnosed with post-traumatic stress disorder, or PTSD.
About the Injection
The shot contains an anesthetic that can reduce PTSD symptoms for several years. In particular, it seems to calm the so-called fight-or-flight reaction to triggering stimuli. Researchers are still unsure about why this treatment is effective for decreasing PTSD symptoms. Information from Cornell University provides two theories.
Theories
The center of the brain, anatomically known as the amygdala, is overactive in PTSD patients. The stellate ganglion is connected with the amygdala, so decreasing signals from this group of nerves may calm the symptoms.
Another theory involves the neurotransmitter norepinephrine, a stress hormone. Individuals with PTSD have an increase in a neuropeptide called nerve growth factor, or NGF. That higher level of NGF boosts levels of norepinephrine in the brain, which worsens PTSD symptoms. A stellate ganglion block injection in Las Vegas interferes with NGF and thus lowers the amount of circulating norepinephrine.
Considerations
Patients may need at least two appointments for two treatments. Doctors providing the injection usually encourage these patients to continue with psychiatric or psychological counseling. They may benefit from prescription medication as well.
