Treatment of painful polyneuropathies.

The treatment of painful polyneuropathies has begun to improve over the past several years. This is based on an evolving understanding of the pathogenesis related to the development of diabetic neuropathy and other diseases that may lead to peripheral nerve injury. Consensus on evaluation strategies for patients presenting with pain has furthered our ability to define neuropathic pain and accompanying signs and symptoms that may respond to particular therapeutic approaches. Recent therapeutic advances in medical management have demonstrated improved outcomes in pain relief. This, along with lower side effect-related issues, has led to improved compliance and patient satisfaction. The assessment and treatment of comorbid conditions, which include sleep, anxiety, and depression, have further advanced the management of painful polyneuropathies in patients. New antiepileptics, antidepressants, and topical therapies have contributed to improved patient outcomes.
