Some personality traits appear to be linked with the risk of developing Parkinson’s disease, a new study suggests.
The tendency to avoid taking risks appears to be a stable personality trait across a patient’s lifetime — as far back as 30 years before symptoms began, those with Parkinson’s disease said they did not often engage in risky or exhilarating activities, such as riding roller coasters or speeding, the study found.
The findings add to a growing body of research suggesting Parkinson’s is more likely to afflict people with rigid, cautious personalities.
It’s possible that what we consider to be aspects of someone’s personality may in fact be very early manifestations of Parkinson’s, said study researcher Kelly Sullivan, of the University of South Florida’s department of neurology. However, much more research is needed to confirm this hypothesis, Sullivan said.(May 1,2012-LiveScience)
One notable exception to the rule is Hitler. He never was cautious or stable.He had opinions, prejudices and his steps into the centre stage of German politics was a gambler’s approach. His bluff was not seriously challenged and never for once he stopped upping the stakes ever higher. History is clear that he was suffering from the disease.
There are those who have Parkinson’s personality and there are those who have not(for example-Hitler); and yet circumstances add up, genetic partly and extraneous conditions also play their part.
Allow me to indulge in my humor: If all the cautious, stable people suffered from Parkinson’s the entire world would have to be shut up. Day to day matters that keep the world run will stop. Do you think it can be left with unstable personalities the kind of fellows who were running Investment banking? The world would go in the way of Baring Bank( now defunct) if Goldman Sachs could get hold of it. Not as yet.

The primary fault in Parkinson’s Disease is the insufficient formation of dopamine. When dopamine fails to form properly the highly damaging superoxide anion is formed instead. This can cause further deterioration in Parkinson’s Disease. Although cell damage is widely claimed to cause Parkinson’s Disease when there is a certain lack of the Parkin gene and it can hasten or aggravate the rate of cell damage.

ADOLF HITLER AND PARKINSON’S DISEASE
The Nazi leader, Adolf Hitler, was known to have Parkinson’s Disease from 1933 until his suicide in 1945 At the end of the Second World War he was largely confined to his bunker in Berlin. In his final days in the bunker, he shuffled around his room, mumbling to himself. His shaking was related to emotional upsets. Physically, he had quickly deteriorated and developed the appearance of an old man. The Nazi hierarchy had throughout tried to conceal his Parkinson’s Disease by all means.(ack: http://viartis.net/parkinsons.disease/news)

What is evolution but adapting things that are already existing? Thus we have some primitive parts from lizards and jellyfish.As a result our brain at its best has to account for what it is built upon.
“Although the things it can do are very wonderful and impressive, its design is very poor engineering in many respects,” says David Linden, a professor of neuroscience at Johns Hopkins University in Baltimore, the author of The Accidental Mind.
These parts may have been OK for their original owners, he says, but they aren’t ideal for us.
Take brain cells, for example.
“They are slow. They are inefficient. They leak signals to their neighbors,”

We’re still using a communication system developed 600 million years ago by jellyfish.
Deep Down, We’re Lizards.
Jellyfish don’t have a brain, but they were the first animal to have any sort of nervous system. It’s a loose network of nerves called a “nerve net,” says Chet Sherwood, who studies brain evolution at The George Washington University in Washington, D.C.
Evolution’s tinkering gave lizards the brain they needed to hunt and survive in a tough world, and our brains still have that ancient wiring.
The brain of an adult human is about three times the size of a gorilla brain.
In evolutionary terms big brain gave our human ancestors bigger volume for brain and it is still evolving and at the root of it we still have the reptilian brain.

Brain has two halves like walnut. These are shot through two worlds: conscious and unconscious mind. our conscious self does not initiate all behaviours. Instead, it is somehow alerted to behaviours that the rest of the brain and body are already planning and performing. Also keep in mind conscious experience does play some moderating role. We think rationally and we speak as though we understand what we speak about. But do we?
Take the matter of religion.
Religion relies on mystery and requires certain rituals and symbols to maintain this mystery. People are ready to defend their faith to death. On the other hand what about the fascination with iPad or iPhone for which people are ready to kill themselves? Or do desperate things disproportionate to the intrinsic value of objects themselves, and sell their kidneys as one did in China only last week? People queue through the night, despite the inclement weather to be the first to grab when shops are opened for business. Are we not seeing Progress masquerading religion in this case? Some Nerd who cannot do anything else makes a jargon and creates applications into program and lo and behold, he is looked upon with wonder. He is a modern shaman. Craze for latest gadgets is controlled by which part of our being? Unconscious mind or Rational mind?
Our brain evolved over some 6 millennia as I mentioned earlier is not the best,- and communication system leaks, and we have no idea which part of it is triggering us?
Brain is our thinking part but it depends how we want to interpret external impressions that we see.
In an earlier post I wrote about Cosmic Mind. We make our experience as basis and draw necessary conclusions from these events around us. If we are thinking from our unconscious mind a little and from conscious mind we cannot tell.
When we look into brain we are going down in time,
