[ 1 ] - Assessment the Possible Association Between Neuromyelitis Optica and Cytomegalovirus as a Provocative Factor

Background: Neuromyelitis Optica (NMO) is an autoimmune inflammation of the central nervous system in which autoantibodies are released against Aquaporin-4 (AQP-4), astrocytic water channels. The disease is characterized by transverse myelitis and optic neuritis. Viruses could be inflammatory agents in the brain. Due to such inflammatory reactions, autoantibodies would cross the blood brain bar...

[ 2 ] - Comparison of Bladder Dysfunction and Urinary Symptoms Between Multiple Sclerosis and Neuromyelitis Optica Spectrum Disorder

Background: Neuromyelitis optica (NMO) and multiple sclerosis (MS) are auto immune demyelinating disorders. Both MS and NMO patients suffer from urinary dysfunction.  Objectives: Investigation of frequency and severity of urinary symptoms in two groups of MS and NMO patients. Materials & Methods: 56 MS patients and 20 NMO patients were enrolled in this cross sectional study conducted in Isfah...

[ 3 ] - Tumefactive Brain Lesions in Patients with Neuromyelitis Optica Spectrum Disorder

Background: Neuromyelitis Optica Spectrum Disorder (NMOSD) is an autoimmune neurological disorder that is characterized by optic neuritis and longitudinally-extended transverse myelitis lesions in spinal segments. Magnetic Resonance Imaging (MRI) findings are part of the diagnostic process in NMOSD patients, and abnormal lesion patterns may cause deviation from a correct diagnosis.  Clinical P...
