It’s Not Concussions That Cause CTE, It’s Repeated Hits!

A recent study found that the neurodegenerative disease chronic traumatic encephalopathy (CTE) can start early and without any signs of concussion. In this study, it was found that, repetitive hits to the head cause CTE. CTE is an Alzheimer’s-like disease that has been most commonly associated with former professional football players, but increasingly with combat sports athletes.

There is an assumption that CTE only affects professional fighters, but the truth is, it can affect the hobbyist in the same way. Most contact oriented approaches to martial arts allow for invariable hits to the head (often sustained and continuous over time). As was seen in this recent study, it is those continues hits that have the potential to cause CTE.

This is why in Crazy Monkey we create a Challenge Play environment, which is always focused on personal challenge, but not at the expense of a students health, or his training partners.

More importantly, Crazy Monkey has something that all other combat sports approaches, or Reality Based Self Defense systems don’t have – a robust, battle tested defensive system, that not only allows our students to be able to engage in the reality of training required to be able to defend themselves – but equally keeps their ‘brains’ safe. It isn’t uncommon in most contact fighting approaches to completely neglect defense all together, in favor of gaining the hit on the opponent. In Crazy Monkey, defense is paramount. Not only from a safety stand point, and preserving our ‘brains’ but equally because good defense, always leads to great offense.

What A Leading Neurosurgeon Has To Say About Crazy Monkey Defense


“As a neurosurgeon I treat people who have sustained head and spine injury. I am particularly concerned about activities that can put someone at risk for either injury to occur. It is for this reason that I have personally chosen Crazy Monkey Defense for my own fitness and self-defense program.

As the name suggests, Rodney has designed a martial art that has at its center the goal of defense – not aggression and attack. The techniques are mouldable to my needs and functional ability whilst providing me with a superb level of safety. I appreciate how the program grows with me – the more knowledgeable and skilled I become, the more complex and experimental I can make my responses.

I also like how the program deliberately and actively embraces a holistic approach to training and performance. CMD is just one part of me – but as it allows me to explore options, think about new techniques, and plan and execute moves in real time it actually replicates and reinforces the surgical decision making part of my life – where I must have the confidence and clarity to make the right decision in an emergency setting.”
