DTDS is an extremely rare disease; only about 20 affected individuals have been described in the medical literature. If both parents have one copy of the mutated SLC6A3 gene, their child will receive two copies of the altered gene and inherit the disease. Dopamine deficiency syndrome is a genetic disorder, meaning a person is born with it. Mutations in the SLC6A3 gene impair or eliminate the function of the dopamine transporter. We have proposed that defects in various combinations of the genes for these neurotransmitters result in a Reward Deficiency Syndrome (RDS) and that such individuals are at risk for abuse of the unnatural rewards. Researchers speculate that higher levels of transporter activity may delay the onset of the disease in these individuals. Science of reward deficiency syndrome RDS results from a dysfunction in the “brain reward cascade,” a complex interaction among brain neurotransmitters in reward centers of the brain, which directly links abnormal craving behavior with a defect in at least the DRD2 dopamine receptor gene ( Blum and Kozlowski 1990a ). von Moers A, Mordekar SR, O'Callaghan F, Wassmer E, Wraige E, Dietrich C, Lewis Here are several to check out, plus tips for wherever you're sleeping.

However, more research is needed to determine the potential short- and long-term side effects. Some researchers also think that it’s more common than previously thought. The resulting shortage (deficiency) of functional transporter disrupts dopamine signaling in the brain. Blackstone C. Infantile parkinsonism-dystonia: a dopamine "transportopathy".

Other signs and symptoms that can develop include abnormal eye movements; reduced facial expression (hypomimia); disturbed sleep; frequent episodes of pneumonia; and problems with the digestive system, including a backflow of acidic stomach contents into the esophagus (gastroesophageal reflux) and constipation. However, serotonin, norepinephrine, GABA, opioid, and cannabinoid neurons all modify dopamine metabolism and dopamine neurons. Studies suggest that the age at which signs and symptoms appear is related to how severely the function of the dopamine transporter is affected. J Clin Invest. The dystonia is widespread (generalized), affecting many different muscles. Brain. The syndrome differs from familial dysautonomia and various other autonomic disorders seen in adults in that the defect can be localized to the noradrenergic and adrenergic tissues. … 2009 How are genetic conditions treated or managed? “Clinically Combating Reward Deficiency Syndrome (RDS) with Dopamine Agonist Therapy as a Paradigm Shift: Dopamine for Dinner?” Molecular Neurobiology, 52 (3), 1862–1869.

This includes medication and lifestyle changes to treat: Infants and children with dopamine transporter deficiency syndrome may have a shorter life-span. Drugs that have similar effects with dopamine (dopamine agonists) are quite useful for managing diabetes. Dopamine transporter deficiency syndrome (DTDS) is a complex disease caused by defects in dopamine uptake within the synaptic cleft and patients manifest parkinsonian features. Dopamine deficiency syndrome is a rare hereditary condition that has only 20 confirmed cases. It is primarily acquired genetically but can also result from prolonged stress. Kurian MA, Li Y, Zhen J, Meyer E, Hai N, Christen HJ, Hoffmann GF, Jardine P, The single largest known environmental factor is low iron levels, which may occur before birth, during infancy or childhood, during pregnancy or later in adult life. As a result, dopamine deficiency is associated with high blood pressure, high cholesterol, weight gain, insulin resistance or diabetes (in other words- with metabolic syndrome), raising the risk for stroke and heart diseases.

However, there is greatly increased dopamine in plasma, cerebrospinal fluid, and urine. The principal symptom of dopamine deficiency is depression, the feeling of boredom (chronic boredom), apathy, loss of satisfaction, chronic fatigue and low physical energy with no desire to move the body. This gene provides instructions for making a protein called the dopamine transporter. The National Institute on Drug Abuse (NIDA) suggest that part of the answer to what causes addiction might be genetic. The chemical imbalance causes physical symptoms. If the amount of dopamine in the cells is too low, it can affect muscle control. Reward Deficiency Syndrome. Lancet Neurol. As the condition worsens, affected individuals develop parkinsonism, which is a group of movement abnormalities including tremors, unusually slow movement (bradykinesia), rigidity, and an inability to hold the body upright and balanced (postural instability). Dopamine is a neurotransmitter that helps the brain process emotions, regulate movement, and experience pleasure. Children with this condition have died from pneumonia and breathing problems.
