Dr Advait Kulkarni (Neurologist in Bengaluru) How do you Diagnose Drug-Induced Neuropathy? Peripheral neuropathy cannot be diagnosed with a single test. A thorough investigation of the patient’s medical history is required to understand the symptoms and the likely cause of symptoms. The physician may advise general blood tests to check diabetes, vitamin deficiencies, liver or kidney dysfunction, metabolic disorders and signs of an abnormal immune system. More specialized neurological examinations could be conducted to check muscle strength and efficiency of nerve conduction; some of these include Electromyography (EMG) and Nerve conduction velocity test (NCV). Magnetic Resonance Imaging (MRI) can help understand muscle quality and identify the cause of neuropathy in tumors or herniated discs. Genetic tests may be suggested to understand the presence of inherited neuropathies. A skin biopsy may be suggested to diagnose any fiber damage. Spinal tap (lumbar puncture) test can be conducted to detect infections, tumors or autoimmune disorders like multiple sclerosis. To know more click the link below http://www.dradvaitkulkarni.com
