There is a lot of clinical and biological similarities between the neurodegenerative conditions of Parkinson’s and multiple systems atrophy (or MSA).
Recently, however, researchers have published a report suggesting that these two conditions may be differentiated from each other using a technique analysing protein in the cerebrospinal fluid – the liquid surrounding the brain, that can be accessed via a lumbar puncture.
Specifically, the method differentiates between different forms of a protein called alpha synuclein, which is associated with both conditions.
In today’s post, we will look at what multiple systems atrophy (MSA) is, discuss how this differentiating technique works, and explore what it could mean for people with either of these conditions.
Getting a diagnosis of Parkinson’s can be a tricky thing.
For many members of the affected community, it is a long and protracted process.
Firstly, there will be multiple visits with doctors and neurologists (and perhaps some brain imaging) until one is finally given a diagnosis of PD. There are a number of conditions that look very similar to Parkinson’s, which must be ruled out before a definitive diagnosis can be proposed.
But even after being diagnosed, there are a group of conditions that look almost identical to Parkinson’s. And many people will be given a diagnosis of Parkinson’s before they are then given a corrected diagnosis of one of these other conditions.
Can you give me an example of one of these other conditions?
Sure. A good example is multiple systems atrophy.
What is Multiple System Atrophy?
Last year – two years after actor Robin Williams died – his wife Susan Schneider Williams wrote an essay entitled The terrorist inside my husband’s head, published in the journal Neurology.
It is a heartfelt/heartbreaking insight into the actor’s final years. It also highlights the plight of many who are diagnosed with Parkinson’s disease, but experience an array of additional symptoms that leave them feeling that something else is actually wrong.
Today’s post is all about Dementia with Lewy bodies (or DLB). In particular, we will review the latest refinements and recommendations of the Dementia with Lewy Bodies Consortium, regarding the clinical and pathologic diagnosis of DLB.

On the 28th May of 2014, the actor Robin Williams was diagnosed with Parkinson’s disease.
At the time, he had a slight tremor in his left hand, a slow shuffling gait and mask-like face – some of the classical features of Parkinson’s disease.
According to his wife, the diagnosis gave the symptoms Robin had been experiencing a name. And this brought her a sense of relief and comfort. Now they could do something about the problem. Better to know what you are dealing with rather than be left unsure and asking questions.
But Mr Williams sensed that something else was wrong, and he was left unsure and asking questions. While filming the movie Night at the Museum 3, Williams experienced panic attacks and regularly forgot his lines. He kept asking the doctors “Do I have Alzheimer’s? Dementia? Am I schizophrenic?”
Williams took his own life on the 11th August 2014, and the world mourned the tragic loss of a uniquely talented performer.
When the autopsy report came back from the coroner, however, it indicated that the actor had been misdiagnosed.
He didn’t have Parkinson’s disease.
What he actually had was Dementia with Lewy bodies (or DLB).
