Summary of "Neurochemical features of idiopathic restless legs syndrome."

The most important traditional hypotheses of the pathogenesis of idiopathic restless legs syndrome (iRLS) involve dopaminergic dysfunction and iron deficiency. However, a possible role of other neurotransmitter or neuromodulators, mainly glutamate, gamma-hydroxybutyric acid (GABA), and adenosine have been suggested in recent reports. Moreover, iron deficiency in experimental models (which causes sensorimotor symptoms resembling those of RLS) is able to induce changes in dopaminergic, glutamatergic and adenosinergic neurotransmission, thus suggesting its crucial role in the pathogenesis of this disease. Relationship between iRLS and opiates, oxidative stress and nitric oxide, and with vitamin D deficiency has also been reported, although data regarding these variables should be considered as preliminary. In this review, we focus on studies relating to neurochemical findings in iRLS.

Medical and Biotech [MESH] Definitions

A disorder characterized by aching or burning sensations in the lower and rarely the upper extremities that occur prior to sleep or may awaken the patient from sleep. Complying with an irresistible urge to move the affected limbs brings temporary relief. Sleep may become disrupted, resulting in excessive daytime hypersomnolence. This condition may be associated with UREMIA; DIABETES MELLITUS; and rheumatoid arthritis. Restless Legs Syndrome differs from NOCTURNAL MYOCLONUS SYNDROME in that in the latter condition the individual does not report adverse sensory stimuli and it is primarily a sleep-associated movement disorder. (Adams et al., Principles of Neurology, 6th ed, p387; Schweiz Rundsch Med Prax 1997 Apr 30;86(18):732-736)

A group of interstitial lung diseases with no known etiology. There are several entities with varying patterns of inflammation and fibrosis. They are classified by their distinct clinical-radiological-pathological features and prognosis. They include IDIOPATHIC PULMONARY FIBROSIS; CRYPTOGENIC ORGANIZING PNEUMONIA; and others.

A condition caused by one or more episodes of DEEP VEIN THROMBOSIS, usually the blood clots are lodged in the legs. Clinical features include EDEMA; PAIN; aching; heaviness; and MUSCLE CRAMP in the leg. When severe leg swelling leads to skin breakdown, it is called venous STASIS ULCER.

A syndrome associated with traumatic injury to the cervical or upper thoracic regions of the spinal cord characterized by weakness in the arms with relative sparing of the legs and variable sensory loss. This condition is associated with ischemia, hemorrhage, or necrosis involving the central portions of the spinal cord. Corticospinal fibers destined for the legs are spared due to their more external location in the spinal cord. This clinical pattern may emerge during recovery from spinal shock. Deficits may be transient or permanent.

An autosomal dominant disorder with an acronym of its seven features (LENTIGO; ELECTROCARDIOGRAM abnormalities; ocular HYPERTELORISM; PULMONARY STENOSIS; abnormal genitalia; retardation of growth; and DEAFNESS or SENSORINEURAL HEARING LOSS). This syndrome is caused by mutations of PTPN11 gene encoding the non-receptor PROTEIN TYROSINE PHOSPHATASE, type 11, and is an allelic to NOONAN SYNDROME. Features of LEOPARD syndrome overlap with those of NEUROFIBROMATOSIS 1 which is caused by mutations in the NEUROFIBROMATOSIS 1 GENES.
