What is the outlook for Neurodegeneration with Brain Iron Accumulation ?
NBIA is a progressive condition. Most individuals experience periods of rapid decline lasting weeks to months, with relatively stable periods in between. The rate of progression correlates with the age at onset, meaning that children with early symptoms tend to fare more poorly. For those with early onset, dystonia and spasticity can eventually limit the ability to walk, usually leading to use of a wheelchair by the midteens. Life expectancy is variable, although premature death does occur in NBIA. Premature death usually occurs due to secondary complications such as impaired swallowing or confinement to a bed or wheelchair, which can lead to poor nutrition or aspiration pneumonia. With improved medical care, however, a greater number of affected individuals reach adulthood. For those with atypical, late-onset NBIA, many are diagnosed as adults and live well into adulthood.
