Our study found lower levels of one type of immune cell – which may even be seen years before a person develops the disease.
Proprioception makes it possible to situate the body in space.
Proprioception is the sense that allows us to rapidly know without looking where each part of our body is.
The protein, called GDF5, plays an important role in the development and function of certain brain neurons.
Neurotrophic factors play an important role in protecting neurons – which is why researchers are investigating them as a treatment for Parkinson's.
Our stomach and brain are connected through the ‘gut-brain axis’.

Our gut microbes play a key role in sending and receiving signals that influence the brain.
Parkinson’s is a motor disease which can affect eye movement.

Parkinson's disease may be diagnosed by looking for subtle changes in eye movements and thinning of retina layers.
A new tool for seeing hotspots in the brain could help doctors detect neurological disorders.

Ozzy Osbourne, famous for biting heads off bats, heavy metal music and a reality TV show, announced he has Parkinson's disease. A Parkinson's specialist explains the disease and recent advances.
Speciality drug prices are so high priced that many patients skip or ration them.
High prescription drug costs are a widespread concern for consumers and policymakers. For patients who need specialty drugs, though, the problem is even worse, with no relief in sight.
Neurostimulation is rife with potential and pitfalls.
From dementia to depression to drug addiction, artificial brain stimulation has been hailed as a landmark medical technology for the future. But safeguards are needed if we want the benefits without the risks.
We knew people with Parkinson’s disease were at heightened risk of developing addictive behaviours like gambling. Our research gives insight into why this is.
About one in six people who take the most common medication for Parkinson's disease will develop addictive behaviours. We found whether this happens depends on a person's unique brain structure.
Low blood pressure may cause problems for many older people.
Researchers are looking for ways to determine who's most at risk for dementia and also ways to detect it early. A scientist who has studied low blood pressure makes a case for a link between the two.
People who have trouble with their speech, say after a stroke, can find it challenging. But a speech pathologist can help.
When people lose their speech, they can stop working and friends can drift away. Here's what we can do to help them get the rehabilitation they need.
Male and female brains are different at every level. Science is continuing to uncover how these differences affect health and disease.
Parkinson's disease is twice as common in men than in women. A sex gene called SRY, found only in men, could go some way to explaining this – and might pave the way for potential treatments.
Sound waves are displayed as an oscillating glow light.
Some treatments for neurodegenerative diseases involve inserting wires into the brain and zapping certain brain cells with electricity. But what if you could do the same thing using sound waves?
An enzyme called TOR could hold the secret to a longer, healthier life.
Thomas Durcan’s lab is using pluripotent stem cells to grow human brain neurons in a dish, in search of a cure for Parkinson’s disease.
Thomas Durcan's lab is growing 3D mini-brains in the search for a cure for Parkinson's disease. Over the next year he is giving all his lab's protocols, methods and results away.

New study challenges traditional view of Parkinson's disease.
Appendicitis is a painful condition caused by an infection of the appendix, a small pouch of tissue attached to the large intestine.
A number of contradictory studies have found a link between Parkinson's and having your appendix out.
Changes in bowel habits occur up to 20 years before the onset of Parkinson's.
Smartphones make great citizen research tools. We take them everywhere and they have the functions (GPS, accelerometers, camera, audio, video) to sense, share and mobilize data between consenting citizens.
We blame electronic devices for our increasingly sedentary behaviours. So why not harness them to study our movement patterns and tackle urgent health crises?
