Between 0.4% and 3.8% of children ages 5 to 18 may have Tourette's; the prevalence of other tic disorders in school-age children is higher, with the more common tics of eye blinking, coughing, throat clearing, sniffing, and facial movements.lthough there is no such thing as a typical case of Tourette syndrome, the condition follows a fairly reliable course in terms of the age of onset and the history of the severity of symptoms. Tics may appear up to the age of eighteen, but the most typical age of onset is from five to seven.
2 doctors agreed: Forehead injury fore: The bruising and swelling are not the concern. The forehead has a lot of blood vessels (very vascular) and small injuries can make big marks. At the beginning after the injury, it is important to watch for dizziness, vomiting, confusion and other signs of concussion. I hope this helps.
The simplest and the most common cause of forehead lumps is simply a reaction to the fact that you have hit your forehead on the hard surface at some point. When this happens, a lump may form and be quite painful to the touch. This is not a cause for concern, and the lump should go away on its own in a few days.
