Hello jones,

Welcome to the NeuroTalk Support Groups.

Yes, concussions, especially repeated, can cause those types of symptoms.

There is a busy
Traumatic Brain Injury and Post Concussion Syndrome Forum

There is a lot of information in what are called the "Sticky" threads at the top of the forum there too. They contain useful websites, introductions, posts on hope and healing, and info about vitamins, etc.. Worth taking a look there.

take care.
