Welcome to the site, we are all here to help each other.
This is a very good place to start.
First, and foremost, many practitioners have their own idea on Concussions - how long to do whatever in a plan - I also had my biggest Concussion in my 60's, and am still dealing with its turmoil, approximately 3 years later.
Forget the numbers of a plan - 6 weeks for this, 2 months for that, etc.
1. REST - means give your brain stimulus free time, even if that means do not read for a day, week, or so.
2. I know we grandparents love our grandkids - tell the kids we have a need for a time-out, and will let them know when its over; explain why, and take some time-out.
3. If you are a working senior, make sure your docs are completing a FMLA form with Undetermined timelimits, and Intermittent time off needs... for Concussion injuries - and list the complaints succinctly.
4. In the Links section at the top of these threads is one from Markin Idaho for a video series that is very useful for any level of Brain Injury that we all recommend victims and family members view to gain some understanding of what is or can be occurring.
Please, keep you head up, you spirits high, we are all here for each other.
Best Wishes,
