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).
What is Dementia with Lewy bodies?
In 2002, deep brain stimulation (or DBS) was granted approval for the treatment of Parkinson’s disease by the US Food and Drug Administration (FDA). The historical starting point for this technology, however, dates quite far back…
Further back than many of you may be thinking actually…
In his text “Compositiones medicamentorum” (46 AD), Scribonius Largo, head physician of the Roman emperor Claudius, first suggested using pulses of electricity to treat afflictions of the mind.

He proposed that the application of the electric ray (Torpedo nobiliana) on to the cranium could be a beneficial remedy for headaches (and no, I’m not kidding here – this was high tech at the time!).

These Atlantic fish are known to be very capable of producing an electric discharge (approximately 200 volts). The shock is quite severe and painful – the fish get their name from the Latin “torpere,” meaning to be stiffened or paralysed, referring specifically to the response of those who try to pick these fish up – but the shock is not fatal.
Now, whether Largo was ever actually allowed to apply this treatment to the august ruler is unknown, and beyond the point. What matters here is that physicians have been considering and using this approach for a long time. And more recently, the application of it has become more refined.
What is deep brain stimulation?
The modern version of deep brain stimulation is a surgical procedure in which electrodes are implanted into the brain. It is used to treat a variety of debilitating symptoms, particularly those associated with Parkinson’s disease, such as tremor, rigidity, and walking problems.
