    If it is bulbar palsy then it must be progressive bulbar palsy which is a LMN disease affecting CNs IX, X, XII and XII.
    Usually affects people in 50's and 60's and is fatal in 10-20 yrs
    It is debated whether it is actually a variant of ALS (UMN and LMN affected)

    So it is probably better to pick ALS since the choice is of bulbar palsy and not progressive bulbar palsy.

    Also ALS is usually fatal in 90% of people within 3-5 yrs and the remainder live about 10 yrs from diagnosis.
    So it seems ALS has the poorer prognosis anyway.
