Kennedy’s Disease vs ALS: How muscle patterns can aid diagnosis and perform as a novel biomarker

Researchers from University College London led by Dr Pietro Fratta and Dr John Thornton found that muscle imaging can help distinguish Amyotrophic Lateral Sclerosis (ALS) from Kennedy’s Disease based on the way specific muscle groups deteriorate in each condition. The method can also help assess the severity of the disease.

ALS is a rapidly progressing condition which affects both upper and lower motor neurones, leading to inability to move limbs and failure of breathing muscles at the later stages of the disease. The complex cause of this condition is not yet fully understood but is thought to be a combination of genetic and environmental factors. Kennedy’s Disease on the other hand is much slower in progression and severity and is primarily caused by a gene mutation.
