What Are the Different Kinds of CIDP?

There can be several types of CIDP. Those subtypes are generally classified based on clinical manifestations.

Typical CIDP is a symmetrical motor and sensory progressive neuropathy affecting proximal and distal muscles with loss of deep tendon reflexes.

Multifocal Motor Neuropathy is a pure motor disorder in which there is asymmetric weakness in the distribution of individual nerves that can be confirmed by diagnostic nerve conduction results.

Lewis-Sumner syndrome is a sensory-motor disorder in which there is sensory loss and weakness in the distribution of individual nerves. Diagnostic nerve conduction studies confirm the focal nerve involvement.

Pure sensory CIDP presents with sensory loss, pain, and poor balance with abnormal gait or walking. There is no weakness but frequently motor nerve conduction studies are abnormal in addition to sensory conduction studies.

Pure motor CIDP presents with weakness and loss of reflexes without sensory loss.

There are other less well-established variants most of which would fall into the category of CIDP.
