Why would a person with motor neurone disease struggle to swallow?

A person with motor neurone disease (MND) may struggle to swallow due to the degeneration of motor neurons that control the muscles involved in swallowing. This can lead to muscle weakness and coordination problems, making it difficult to initiate or complete the swallowing process. As the disease progresses, the affected muscles may become increasingly unable to function properly, resulting in a higher risk of choking and aspiration. Additionally, the loss of sensation in the throat can further complicate swallowing.
