The Silent Three
In addition to the more obvious physical symptoms that you or your child may experience when afflicted with a concussion, there are also the "Silent Three," or the harder-to-detect symptoms.
The silent symptoms of concussion are most often noticed by observers such as parents, siblings or teachers. This is often the case because these are not physical symptoms which can cause the child pain, but rather changes in cognizance which can alter how the child interacts with their environment.
In other words, there is a potential change in one or more of the child's usual patterns such as the way that they think, sleep or act.
These symptoms may be clues that your child has a concussion:
If your child has more trouble getting to sleep, staying asleep or is sleeping more or less than usual and/or appearing more tired than usual, this may be an indication of concussion.
If you notice a change in your child's personality (i.e. they seem more irritable, sad/depressed, anxious/nervous or impatient), or they are having more frequent and severe mood swings, they may be suffering from a concussion.
If your child (or an adult) appears slower to remember something when learning new information, has difficulty concentrating (such as in school or at work) or seems to be 'in a fog,' they may be suffering from a head trauma.
