shayan,

Welcome to NeuroTalk. Please feel welcome to introduce yourself and tell us how we can help you.

We have discussed G forces on the brain many times. 1 G has no effect on the brain. It is constantly subjected to 1 G. Just walking down stairs can subject the brain to 1.5 to 2 G's. A sub-concussive impact is usually 10 to 20 G's or more.

Most of the matter in the brain has very similar densities which relates to mass with relates to differences in acceleration and deceleration. Shearing is more related to rotational forces as the skull tries to prevent the brain from rotating inside the skull while rotational forces try to keep the brain tissues rotating. There are also shock waves that travel through the brain starting at the point of impact that also damage tissue.

Roller coasters are usually rated for acceleration/deceleration and up and down G's but rarely for side to side G's. Side to side G's can be the worst because they can cause the head to impact the safety bars increasing the G force at impact.

My doctor suggested that depression is due to the brain being less tolerant of life stresses, emotional, physical, chemical. Mitigating those stresses should reduce depression. Learning to live with your dysfunctions and limitations is the first way to reduce those stresses. Then, the achievement of learning work-arounds to be productive enhances stress reducing chemistry ( dopamine, etc).

Finding new ways to memorize and process information can go a long way toward achieving your dream. Many find they need to change from a single learning system (auditory/lecture or visual/reading) to a combined system. Reading out loud to oneself can be helpful. Most secondary schools have programs to help with some of these struggles. Sitting at the front of the class/lecture hall can be helpful.

So, please tell us more about how you are doing.

My best to you.
