Emotional reactions may be affected, causing inappropriate laughing or crying, which can be distressing for both the MND person and their family. It is important to realise that these symptoms are part of the disease. Respiratory difficulties occur if the muscles involved in breathing are affected and in a few cases this may be the predominant feature of the disease. It must be stressed that MND affects each individual differently with respect to initial symptoms and the rate and pattern of the progression of the illness. Bowel and bladder functions are not directly affected by MND, although there may be disturbance of bowel function in the later stages because of immobility and dietary restriction and bladder function may be affected because of limited fluid intake.
Sexual function remains unaffected in many people until a late stage.
Eye muscles are not affected, with people retaining the ability to move their eyes. As it is a progressive condition, it is important to plan ahead and find out what services or equipment are available or needed.
