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. Continue reading →
Magnetic Resonance Imaging (MRI) technology is advancing rapidly as a tool for diagnosing and monitoring disease. In MND, MRI scans are used to understand changes that happen to the brain because of this disease.
Prof Nigel Leigh
Prof Nigel Leigh from the Brighton and Sussex Medical School (University of Sussex) is carrying out a study looking into changes to motor neurones using a new imaging method (our reference: 824-791).
Neurite Orientation Dispersion and Density Imaging (NODDI) is a type of MRI scan, and can see whether MND is affecting specific parts of motor neurones, called neurites, found within the brain. Neurites are the tiny parts of the nerve cells that branch out from the main body of the nerve cell, and are important in the functioning of the brain.
Prof Leigh and his team hope that the new imaging approach will tell us more about the sequence of events that cause motor neurones die, and how this relates to the symptoms of people with MND. Continue reading →
Plenary speaker Dr Massimo Filippi put this question to delegates on the second day of the 24th International Symposium on ALS/MND.
Opening the session on neuroimaging, Dr Filippi gave an excellent review on what we currently know about this area of research, and ultimately answering whether or not we can see more clearly in MND?
Neuroimaging – now and then.
It’s all in your head – Magnetic Resonance Imaging (MRI)
Over the past ten years there have been significant advances in the identification of neuroimaging patterns in MND. Dr Filippi focused mainly on the use of MRI neuroimaging (a technique used to visualise changes in the brain). He stated: “Through the use of MRI we have been able to detect cortical thickness of the Cerebral cortex (the outermost layer of the brain), which is significantly reduced in MND”.
