mrsbjr,

Welcome to NeuroTalk. Sorry to hear of your struggles.

It sounds like you have been getting some very mixed up information.

First, there are two risks from getting a second concussion. The more common risk is multiple impact syndrome. It just means your symptoms will likely be worse than the first and likely to last longer.

The more important risk is Second Impact Syndrome. It is when your brain has lost control over intracranial fluid pressure from the first concussion and has not regain this control before a second concussion. This reduces as time passes since your concussion. Many consider the risk to be gone by 6 weeks after a concussion unless extreme symptoms persist. Others suggest even less time. Your neuro's comment does not fit with basic understanding of Second Impact Syndrome. If your PCS symptoms were enough to put you at risk, they would also prevent you from returning to work.

Plus, your continuing symptoms make a difference. If you are still having bad head aches, you risk would be higher. If you are just struggling with light and sound sensitivity and insomnia and the like, your risk is virtually non-existent.

At 18 months since your concussion and able to be at work for so long, your risk is not much different than anybody else's risk.

What PCS symptoms are you still having ?
