Tics can be a way to release tensions
If your child has developed a nervous tic, do not despair. In principle, a nervous tic may disappear over time without major importance, and does not respond to any disease or problem. Tics can be a way the child finds to release tensions. If the tics need anything, it's patience.
A nervous tic is the sudden, imperative and involuntary execution, at irregular, but related, intervals of simple, isolated or united movements, which, objectively, would seem to tend towards a specific objective. Its execution is often preceded by a need that, if repressed, causes discomfort. Will and distraction can suspend them. Generally, they also disappear during sleep.
A tic is not a bad habit
The constant flickering, winks, grimaces, carrasperas, tongue clicks, knuckle cracks or eyebrows are nervous tics, which worry many parents because they think their children do it on purpose or because they want to. And it is not like that. A tic is not a bad habit, but an involuntary act. It is a compulsive act that probably helps children release their tensions.
Nervous tics may appear unexpectedly as disappear by surprise, in the same way. Parents should worry when they see that their child suffers with his nervous tic. If this habit is bothering or harming you in your daily life it is necessary to consult with your pediatrician.
On the other hand, in other cases, when the child does not feel upset, it is important not to discuss the issue with them at all hours, and wait patiently for it to happen. The duration of a tic is variable. It can last from one month to more than one year. The most common is a blink or a facial movement, although the entire head, torso or extremities may also be affected.
