You are carrying out physical activity and notes something wrong: Only half of your face appears red and sweaty, while the other is completely dry. Know that it could not be only a strange reaction of the body, but the manifestation of a pathology in progress. In fact, the so -called asymmetrical sweatingrepresents an alarm bell for two rare neurological conditions: the Arlecchino syndrome and the Horner syndromepathologies responsible for attacks on the sympathetic nervous system. Both manifest themselves with a different symptomatology – the similarities are limited to the case of partial sweating – which is worth knowing.
A nervous system under stress
Our body has a complex automatic adjustment system, which provides for the so -called nice nervous systemresponsible for the control of several vital functions such as heartbeat, breathing and sweating. It forms part of the wider autonomous nervous system and is activated in stress situations or during physical activity.
When this delicate mechanism suffers damage, particular symptoms can emerge. The nice chain, located in front of the spine, transmits the nerve signals that regulate the sweating and dilation of the blood vessels of the face, and damage to this chain can cause problems on one side of the body.
Arlecchino syndrome: when half face changes color
Arlecchino cause syndrome redness and sweating on only one side of the face, neck and chest. The other side remains completely dry and maintains the normal color of the skin.
The condition takes its name from the two -tone mask of the famous art comedy character. Symptoms appear when the sympathetic nervous system is activatedfor example during:
The symptoms are temporary and can last from a few minutes to a few hoursuntil the body has cooled. The demarcation line between the affection and normal side follows exactly half of the body, as if it were traced with a ruler from the center of the front to the chest.
Horner’s syndrome: beyond sweating
Horner’s syndrome has a classic triad of symptoms that affect only one side of the face:
Unlike Arlecchino syndrome, Here the main problem is the absence of sweating, not excess.
There Restricted pupil and the falling eyelid They make this condition more easily recognizable even at rest.
The causes: when the nerves are damaged
In most cases ,. The researchers believe that it depends on an interruption in communication between the nerve cells of the two sides of the body.
The triggering factors may include:
There Front cervical surgery It represents a particular risk: during these interventions, surgeons operate on the spine of the neck accessing the front, and the proximity to the nice chain increases the risk of accidental damage.
Numbers and diagnosis
It is estimated that Less than 1,000 people in the United States suffer from Arlecchino syndrome. The condition was described for the first time in 1988, relatively recently in the history of medicine.
Diagnosis requires:
It is possible simultaneously suffer from both syndromessince they share the same basic mechanism: the damage to the nice chain.
Living with asymmetrical sweating
There Arlecchino syndrome is not dangerous for life and does not affect the life expectancyTherefore many people learn to live with symptoms without the need for treatment.
The Therapeutic options depend on the case below:
In some cases, symptoms can resolve spontaneously over time. Other patients experience symptoms only in specific situations, learning to predict and manage episodes.
When to consult a doctor
The sudden appearance of asymmetrical sweating always deserves one medical evaluation. Even if rarely indicator of serious problems, it could report the presence of:
A neurologist will be able to distinguish between the Arlecchino syndrome and that of Horner through specific tests and draw up one diagnosis precise, which will allow you to identify any causes negotiable and provide reassurances to the patient on the path to take.
The point is that Asymmetrical sweating represents a signal of our body that deserves great attention. With the right diagnosis and, when necessary, the appropriate treatment, most people can Continue to live a normal and active lifeas long as I respect the medical precepts about it.
