Chris and Jason have long been interested in the long term effects of concussion and head trauma. This week on the Recombobulator Lab they are joined by Dr. Ryan Takagi, nutritionist, chiropractor mechanical engineering PHD candidate. Ryan’s PHD is specifically looking at the prolonged after effects of concussion and how sleep impacts this.

Chronic traumatic encephalopathy (CTE) brain condition thought to be linked to repeated head trauma. Unfortunately, the only way to diagnose CTE is through an autopsy, making it difficult to determine the extent of the problem in living patients. Symptoms of CTE can be similar to those of ADHD or depression, making it even more challenging to diagnose.

Ryan became interested in CTE as a chiropractor, observing patients who had prolonged symptoms after a concussion. He wondered why some people made a full recovery from concussion while others had prolonged symptoms.

Jason mentions that his son has had a lot of concussions from a variety of sports and activities and Jason wonders whether he should be worried. Ryan says there are a number of studies looking into potential neurodegenerative problems that may arise from repeated concussions or subconcussive events, such as too many headers in soccer.

One of the methods used in these studies is the use of accelerometers in mouth guards or helmets. These devices can track the impact of hits to the head and provide data on where on the field there is more impact and at what age people can handle these impacts. This data can be used to help determine when certain elements of sports should be introduced, such as contact in baseball or headers in soccer. Ryan’s team are also using these in their research.

Ryan's research explores the relationship between concussions and sleep. His research is looking at two things:

1. How a concussion results in injury to sleep centers thus causing sleep disturbances
2. How these sleep disturbances impact recovery
