Symptoms of PD include tremor (trembling in hands, arms, legs, jaw, and face), rigidity (stiffness of the limbs and trunk); bradykinesia (slowness of movement) and postural instability (impaired balance and coordination). As these symptoms become more pronounced, patients may have difficulty walking, talking, or completing other simple tasks.
