Down syndrome gets its name from the British doctor, John Langdon Down, who first clinically identified the condition in 1866. The actual chromosomal nature of Down syndrome did not become documented until 1959 by Dr. Lejeune. However, Down's name remains associated with the condition.

What distinguishes Asperger's Syndrome from autism is the severity of the symptoms and the absence of language delays. Children with Asperger's may be only mildly affected and frequently have good language and cognitive skills. To the untrained observer, a child with Asperger's may seem just like a normal child behaving differently. They may be socially awkward, not understanding of conventional social rules, or show a lack of empathy. See similar questions...

Syndrome" is a medical term for a condition in which there is a collection of signs (observable body changes) and symptoms (problems observed by the patient) recognizable by a doctor's exam. Individuals with a syndrome may not have all of its associated signs and symptoms, but they must have enough to be considered "diagnostic." Conversely, because someone may display some of the signs and symptoms of a syndrome, does not necessarily mean they have it. See similar questions...

HELLP Syndrome occurs in 4 percent to 12 percent of the women who have preeclampsia. It is one of the most severe forms of preeclampsia. HELLP stands for: hemolysis, elevated liver enzymes, and lowered platelets. HELLP Syndrome most often affects the liver, causing stomach and right shoulder pain. HELLP Syndrome is most dangerous because it can occur before you exhibit the classic symptoms of preeclampsia. It is often mistaken for the flu or gallbladder problems. See similar questions...

Only 3 to 5% of cases are inherited; the rest arise as an accident of chromosome arrangement during meiosis. For details, see my essay on the origin of trisomy 21 or Dr. Paul Benke's essay on the types of DS, and the risk and recurrence risk of DS. No. Down syndrome occurs at conception, so nothing in the pregnancy can cause Down syndrome to occur. As for prior to conception, the research all shows that drug or alcohol use does not increase the risk of having a child with DS. See similar questions...

Tourette Syndrome TS) is a neurological disorder characterized by tics -- involuntary, rapid, sudden movements or vocalizations that occur repeatedly in the same way. See similar questions...

Down's Syndrome is a genetic condition caused by extra genetic material (genes) from the 21st chromosome. The extra genes cause certain characteristics that we know as Down's syndrome. Individuals with Down's Syndrome also have all the other genes given to them by their parents. As a result, they have a combination of features typical of Down's Syndrome on top of the individual features from their parents. See similar questions...

No. There is nothing you did before or during the pregnancy or after your child was born to cause fragile X syndrome. Fragile X syndrome is genetic which means it is caused by a change in a gene, in this case, the FMR1 gene. The change causes the gene not to work the way it should, leading to the problems seen in fragile X syndrome. Because fragile X syndrome is genetic, it can be passed on and you are at risk for having another child with fragile X syndrome. See similar questions...

ANSWER: Hans Asperger, an Austrian scientist in 1944, discovered the syndrome. He found out why children and adults behaved differently from other people and linked it with autism, except that he found that these people had average or above average intelligence. The disability was named after him of course, but would it have had a better ring to if I discovered it for example and it was called Handley Syndrome? Autism however was discovered by Leo Kanner a few years before Asperger. See similar questions...

Firstly the bipolar disorder. Manic depressive persons show various striking symptoms, absent in Beethoven. In manic periods they are overactive, they hardly sleep or eat and sometimes they want to buy the Empire State Building (or behaviour the like). In depressive periods they hardly leave their beds and the only thing they want is to die. Often such patients are unable to take care of themselves, at least those who don't get modern medicines. In Beethoven's days such medicines didn't exist. See similar questions...

A1. SARS is an infectious disease of the respiratory system characterized by an atypical inflammation of the lungs (pneumonia). While a definitive identification has not been made, CDC announced that its scientists have detected a previously unrecognized coronavirus in patients with SARS. These findings are preliminary and do not provide conclusive evidence that coronavirus is the cause of SARS. See similar questions...

Acute coronary syndrome, defined in the protocol as unstable angina excluding patients with a definite MI, was included in the primary composite endpoint that was designed to capture all cardiovascular events. The main secondary combined endpoint was designed to evaluate more objective and life-threatening endpoints. There were fewer acute coronary syndrome events seen in the pioglitazone group (n=42) compared with the placebo group (n=63). Back to the Top See similar questions...

The long QT syndrome (LQTS) is causing an abnormality of the heart's electrical system. The mechanical function of the heart is entirely normal. The electrical problem is due to defects in heart muscle cell structures called ion channels. These electrical defects predispose affected persons to a very fast heart rhythm (arrhythmia) called "Torsade de Pointes" (TdP) which leads to sudden loss of consciousness (syncope) and may cause sudden cardiac death. See similar questions...

The diagnosis is commonly suspected or made from the electrocardiogram (ECG). All children and young adults should have an ECG as part of their evaluation for an unexplained loss of consciousness episode. On the other hand, there is the possibility to check blood samples for known gene mutations that cause LQTS. See similar questions...

Poland syndrome is a unique pattern of one-sided malformations that are present at birth. Poland syndrome is characterized by a defect of the chest (pectoralis) muscle on one side of the body and webbing of the fingers (cutaneous syndactyly) of the hand on the same side (ipsilateral hand).

For a long time we thought that individuals who were in a state of diminished consciousness were unable to respond. Through years of working with people with severe brain injuries and diminished responding capacities we have learned that the person may be receiving information but be unable to produce an effective response. Some people may communicate with an eye blink, a facial gesture or even by moving a toe. See similar questions...
