Head issues


Hello, when I was a child, I hit my head against a hard object, resulting in a slight indentation about the size of a ten-dollar coin near the center of my scalp.
The indentation is noticeable to the touch, and it can also be seen when I press down on my hair.
There have been no external injuries or discomfort since then, and the indentation has persisted for about twenty years.
I would like to ask the doctor if this condition is unlikely to have any impact on my head.
If I do not experience any discomfort in the future, should I just ignore it? Thank you!

Yū, 20~29 year old female. Ask Date: 2017/11/29

Dr. Zhang Junwei reply Neurosurgery


Basically, no.

Understanding the long-term effects of childhood head injuries is crucial, especially when considering the potential implications of past trauma on cognitive and physical health. In your case, having experienced a head injury that resulted in a slight indentation on your skull, it is understandable to have concerns about any lasting effects.

Firstly, it is important to note that the human skull is designed to absorb and distribute impact forces. In many cases, minor head injuries, such as the one you described, do not lead to significant long-term consequences. The indentation you feel may be a result of localized bone remodeling, which can occur after trauma. If there were no accompanying symptoms such as persistent headaches, dizziness, cognitive difficulties, or other neurological signs, it is likely that the indentation itself is not a cause for concern.

Research indicates that most individuals who experience mild head trauma, such as a bump or a fall, do not suffer long-term cognitive deficits. The brain has a remarkable ability to heal and adapt, especially in childhood when neuroplasticity is at its peak. However, the degree of impact and the specific area of the brain affected can play a role in determining whether any long-term effects might occur. For instance, injuries that result in significant concussions or that affect areas of the brain responsible for memory, motor function, or emotional regulation may lead to more pronounced effects.

In your case, since you have not experienced any discomfort or symptoms in the two decades following the injury, it is reasonable to conclude that the indentation is likely benign. However, it is always wise to remain vigilant for any new symptoms that may arise. If you ever experience changes in cognitive function, memory issues, or any neurological symptoms, it would be prudent to consult a healthcare professional for a thorough evaluation.

As for the question of whether you should be concerned about the indentation, the general consensus in the medical community is that if there are no associated symptoms, it is typically safe to monitor the situation without taking any immediate action. Regular check-ups with a healthcare provider can help ensure that any potential issues are identified early.

In terms of prevention for future injuries, it is essential to take precautions, especially in environments where falls or impacts are likely. Wearing helmets during activities such as biking or skateboarding, ensuring safe play areas for children, and being mindful of potential hazards can significantly reduce the risk of head injuries.

In conclusion, while your childhood head injury may have left a physical mark, it does not necessarily indicate a risk of long-term cognitive or physical impairment, especially in the absence of symptoms. Continuing to monitor your health and being proactive about safety can help mitigate any future risks. If you have any lingering concerns or experience new symptoms, seeking medical advice would be the best course of action.
