Spastic quadriplegia

Spastic quadriplegia, also known as spastic tetraplegia, is a subset of spastic cerebral palsy that affects all four limbs.

Symptoms and signs
Spastic quadriplegia can be detected by the abnormal development of motor skills in children. Symptoms can present themselves as early as three months but are generally seen before the child reaches two years of age. Some warning signs include: a child of more than two months who has stiff legs that scissor and is unable to control their head, and a child of more than twelve months who has not developed the ability to crawl or stand. Spastic quadriplegia also presents a range of symptoms that affect the musculature. Many experience contractures, which are defined as joints that cannot be stretched or moved. Clonus is another symptom that is characterized by alternating, rapid muscle contraction and relaxation. This presents itself as tremors and scissoring of the limbs. Dystonia, or lasting muscle contractions and tightness, is also often experienced by those affected by spastic quadriplegia. These involuntary muscle contractions may affect the development of structural muscle around the hip and lead to hip dysplasia and dislocation, making it difficult to sit. The combination of these symptoms often makes it difficult for the patients to walk as well. Although the arms and legs of patients are often stiff, the neck is usually limp due to the lack of voluntary muscle control. ==Causes==
Causes
Spastic quadriplegia is generally caused by brain damage or disruptions in normal brain development preceding birth. According to the National Institutes of Health, there are four types of brain damage that can cause spastic quadriplegia. These include damage to the white matter (periventricular leukomalacia), abnormal brain development (cerebral dysgenesis), bleeding in the brain (intracranial hemorrhage), and brain damage due to lack of oxygen (hypoxic-ischemic encephalopathy or intrapartum asphyxia). A difference in blood types between the mother and the fetus can also initiate a problematic immune response and cause brain damage. Severe jaundice, can also lead to brain damage and spastic quadriplegia due to a buildup of bilirubin in the blood. == Diagnosis ==
Diagnosis
Spastic quadriplegia can be diagnosed as early as age one after a noticed delay in development, particularly a delay in rolling, crawling, sitting, or walking. However, depending on the severity, signs may not show up until the age of three. Muscle tone is sometimes used to make the diagnosis for spastic quadriplegia as affected children often appear to be either too stiff or too floppy. Disorders within the group are classified based on two characteristics- the main physiological symptom, and the limbs that are affected.

Research
Doublecortin positive cells, similar to stem cells, are extremely adaptable and, when extracted from a brain, cultured, and then re-injected in a lesioned area of the same brain, they can help repair and rebuild it. The treatment using them would take some time to be available for general public use, as it has to clear regulations and trials. ==Notes==
