There are many online support groups for people who have had concussions or post-concussion syndrome. These groups can offer emotional support, information, and advice from others who have gone through similar experiences. Some of the online support groups that I found are:

• Post Concussion Syndrome Support Group: This is a Facebook group with over 10,000 members who share their stories, questions, and resources about concussions and post-concussion syndrome. You need to apply to join the group and answer a few questions.
• Concussion subreddit: This is a Reddit forum where you can read and post comments about concussions and related topics. You can also find links to other subreddits, such as post-concussion syndrome and TBI (traumatic brain injury).
• PINK Concussions: This is an organization that focuses on the needs of women and girls with brain injuries, including concussions. They have 14 online support groups for different categories of members, such as women over 25, BIPOC, veterans, caregivers, and clinicians.

These are just some examples of online support groups that you can explore. You can also search for local or in-person support groups in your area by contacting the [Brain Injury Alliance] or the [National Association of State Head Injury Administrators].
