It’s not just about the neurones

Long before the latest wave of cellular and molecular biology advances started to give us new information on what was going on at the cellular level in MND, some doctors had observed that if the disease started in one particular part of the body, it would be neighbouring parts that became affected next.  This suggested that the disease usually starts in a single part of the brain or spinal cord before spreading further, like ripples in a pond.

How this happens is not well understood. It is likely that there are a number of processes going on, but they can broadly be divided into two theories. One of these is that damaged proteins can leak out of sick neurons and ‘infect’ their neighbours – a subject we have discussed at previous international Symposia.Read More »
