Article Summary: The brain damage sustained after a concussion is not always immediately apparent…and the effects can be long lasting A blow to the head that knocks a person unconscious can result in widespread loss of brain tissue …and this is why some people who suffer head injuries are never quite the same.


“Compare it (your head) to a jelly in a bowl. The bowl is the skull – a strong, protective container – and the jelly (the brain) is nestled within. The skull is able to withstand many types of blows; but the brain is vulnerable to sudden swirling or rotating movements. Shake the bowl and see what happens to the jelly.”

– Don Mackie, Emergency Specialist, Hutt Hospital, Wellington, New Zealand

Different mental abilities are located in different parts of the brain, so a head injury can damage some, but not necessarily all, skills such as speed of thought, memory, understanding, concentration, solving problems and using language. The cognitive effects of a brain injury affect the way a person thinks, learns and remembers. Brain damage leads to difficulty in making decisions, processing information quickly, problem solving and especially coming up with different solutions in a pressured environment of stress. (So I most like writing and “dealing with people” in a relaxed environment!).

The more severe the injury, the more brain tissue is lost. “There is more damage and it is more widespread than we had expected,” said Dr Brian Levine of the Rotman Research Institute and the University of Toronto, whose new study appears in the journal ‘Neurology’. Dr Levine studied brain scans taken from 69 traumatic brain injury patients whose head injuries ranged from mild to moderate or severe. Canadian researchers ran a computer analysis of these images and found that even patients with mild brain injuries with no apparent scarring had less brain volume. “When you have a blow to the head, it causes a neuro-chemical reaction in the brain cells that leads to cell death,” Dr Levine said. “The more cells that die, the less tissue you have. The amount of tissue loss seems to be related to the severity of the injury – how long the person was knocked out.”

Brain injury may prompt one area of the brain to be “reassigned” and take over the function of another. Professor Richard Faull from the University of Auckland (New Zealand ) explains simply: “Think of it as a sort of emergency breakdown service (‘We Fix Neurons — Fast!’). It is literally like a little highway; but instead of going directly from Auckland to Wellington, it goes to Whangarei, to Taranaki, then to Wellington! The route is highly distorted and there may be all sorts of reasons for that.”

Dr Brian Levine said the Rotman Research Institute study helped to explain why some people with brain injuries often struggled with memory problems, mood changes, confusion and reduced information-processing speed. He also said the damage was greatest to white matter, tissue that makes up the brain’s communication network. “What you have basically is a loss of brain connectivity. That is essential for efficient processing in the brain. When you have a subtle loss of that, even if it is 5 to 10 per cent, it will have a large effect on behaviour.”

“The study does not mean that people who have had mild head injuries would have a disability, but it might help to explain why some people never quite recovered from their injury. You hear this all the time from people, that they’re not the same. A lot of times doctors don’t know why.”

With knowledge comes understanding and acceptance.

Don’t see head injury as a ‘handicap’, but view it as just another challenge to live with, work around and overcome in the amazing journey of life.

“Success to others may be apparent in what you DO; but significance, meaning and purpose lies, then reveals itself in what you ARE and BECOME down the ‘river of life’ – how and the spirit with which you face, then overcome the daily obstacles, the frequent trials and tribulations along the often rocky path-way of life’s magical and mysterious journey. Light your path brightly.”

PS: To end off, enjoy these thoughts…

We have it within; but we get it all from without. There is a well-spring of strength, wisdom, courage and great imagination within each one of us; but once we draw on this truth, it gets watered from without, by a Higher Source – the Source of Life and Love, which is God, the very Ground of our Being.”

When you can see no light at the end of the tunnel, light your own candle and let your light illuminate the world, like the radiance from a window at midnight.”

That’s a metaphor, BTW”

“The task ahead of you can always be overcome by the power within you…and the seemingly difficult path ahead of you is never as steep with the great spirit that lies within you.”

“When the world is filled with love, people’s hearts are overflowing with hope.”

About craig lock

About the Author Craig has a 'passion' for writing books that tell stories about people doing positive things in this often so hard, sometimes unkind world, occasionally cruel, yet always amazing world - true stories that leave the reader feeling uplifted, empowered and hopefully even inspired. Craig Lock loves to encourage and empower people to be the best they can possibly be, and to create what they want in life. Craig has learnt plenty from the "school of life" (still "battered and bruised") and also from a few "hard knocks on the head". He is an extensive world traveller (on a "shoestring budget") and failed professional emigrater who has spent most of his life’s savings on airfares. He is still sliding down the razor blade of life on the beautiful undiscovered island that is New Zealand, somewhere near the bottom (rude!) of the world near Antarctica. There he talks to the 60 million sheep! Craig has been involved in the corporate world (life assurance) for "many moons". However, through a rather strange (and unique) set of circumstances and finding himself in a small town near the bottom of the world ...and with nothing else to do, he started writing. That was five years ago. Five published books later and having written another twenty manuscripts (now 300 + on widely differing subjects - well what else is there to do here?)... this is where Craig is in the "journey/adventure" that is life. Craig has run a run a successful creative writing course (not teaching sheep!) at the local Polytechnic. He was the author of (as far as we know) the first creative writing course on the internet. He has many varied interests and passions and is particularly interested in the field of psychology – studying the human mind and what makes different people "tick-tock grandfather clock". He is fascinated by the "overlap between psychology and the dimension of spirituality". One of his missions in life is helping people make the most of their hidden potential and so finding their niche in life... so that they are happy. Craig’s various books probably tell more about his rather "eventful" life best (no one could believe it!). He writes books with serious messages and themes, then as a contrast "rather crazy, wacky stuff"…to keep him sane here. As an ‘anonymouse’ person wrote: "All of us are born mad; some of us remain so." Well nothing else much happens in quiet provincial New Zealand, other than headlines like "Golf Ball Thrown at Policeman" and "Beach Toilet Closed for Season.". True! from For Craig’s books see AMAZON at ... but rather GO to ?? When the writer is no more, the value of your purchase will soar." All proceeds go to the needy and underprivileged… and a charity (most worthy-Bill and I) “When the writer is no more , the value of your purchase will soar! “ “Together, one mind, one life (one small step at a time), let’s see how many people (and lives) we can encourage, impact, empower, enrich, uplift and perhaps even inspire to reach their fullest potentials…and strive for and perhaps one sunny day even achieve their wildest dreams.” PPS Don’t worry about the world ending today… as it’s already tomorrow in scenic and tranquil ‘little’ New Zealand
