Gait difficulty, slowing is features of parkinsonism.
Early falls and autonomic features may be due to multiple system atrophy. The drug response in such a case is difficult.
The drugs available are levodopa / carbidopa, amantadine, pramipexole, rasagiline, entacapone.
The dosage and combinations are tried one by one and requires lifelong therapy.
