Four motor symptoms are considered cardinal signs in PD: slowness of movement (bradykinesia), tremor, rigidity, and postural instability.

[2] The diagnosis is controversial, as people with a physical illness can be misdiagnosed with it.
Of all the circuits, the motor circuit is the most studied due its importance to motor disorders. The direct pathway of the motor circuit is one in which projections from the cortex travel to the putamen directly to the internal segment of the globus pallidus (GPi also known as GP-Medial) or the substantia nigra, pars reticulata (SNr) and are then directed toward the ventral anterior nucleus ...
Multifocal motor neuropathy (MMN) is a progressively worsening condition where muscles in the extremities gradually weaken.The disorder, a pure motor neuropathy syndrome, is sometimes mistaken for amyotrophic lateral sclerosis (ALS) because of the similarity in the clinical picture, especially if muscle fasciculations are present.
