Improving the classification of ALS – can we make it logical?

Yesterday at the International Symposium on ALS/MND Prof Ammar Al-Chalabi (Director of King’s Care Centre and Professor of Complex Genetics at King’s College London) cautioned the motor neurone disease (MND) research community about the confusing way we describe this disease we are all fighting. He started his talk by showing a standard definition of what MND is, and then pointed out some of the areas that were inconsistent – or has he put it, illogical.

For example is MND described by: whether it affects the motor neurones running from the brain to the spinal cord (upper motor neurones) or from the spinal cord to the muscles – whether that’s in our hands, arms or feet (lower motor neurones)? Or is it defined by where the symptoms appear – in what Prof Al-Chalabi described as the geography – either with speech and swallowing problems, or foot drop, or clumsiness / loss of dexterity in the hand?

Asking the Dr Spock question..

To illustrate his point he shared the results of a survey he’d carried out with over 100 neurologists across Europe, North America and Australia. Firstly he asked them what terms they used to give definitions of MND, ranging from amyotrophic lateral sclerosis (ALS), primary lateral sclerosis (PLS) and progressive muscular atrophy (PMA) to ‘classical’ MND – from a list of 26 descriptions, all of them were used!Read More »
