Spinal muscular atrophy type 1: what are the ethics and practicality of respiratory support?

Spinal Muscular Atrophy Type I (SMA I) is the most severe form of SMA. It presents in infancy and without treatment death occurs by 2 years. Treatments in use address respiratory and nutritional issues but even with aggressive treatment death is still likely in childhood. Thus their use is not obligatory. However, pediatric respirologists must be willing and comfortable at presenting all treatment options, including the option of palliative care, to families and then supporting the family's choice. Whatever the chosen treatment regimen, decision making is difficult for families. Support and help must be provided from the time of presentation till death by a knowledgeable and compassionate team.
