Down's disease (Mongolism)

Okay, I will write an article on the topic "Down's disease (Mongolism)".

Down's disease, also known as Down syndrome, is a genetic disorder that causes a person to have mental retardation and physical features such as a distinctive facial shape and folds of skin on the eyelids. The name "Mongolism" was used previously, but is now an outdated and incorrect term as it may cause offense.

Down syndrome is caused by the presence of an extra copy of chromosome 21. Normally a person should have two copies of this chromosome, but people with Down syndrome have three copies. This may occur due to improper segregation of chromosomes during the formation of sperm or eggs, or during early embryonic development.

Down syndrome is the most common genetic disorder in humans. It occurs in approximately one in 700 newborns. Although people with Down syndrome have physical and mental characteristics, each person is unique and has their own individual abilities and interests.

Symptoms of Down syndrome may include developmental delays, muscle weakness, vision and hearing problems, and an increased risk of certain diseases, such as heart and gastrointestinal problems. Some of these problems can be improved or treated.

People with Down syndrome can have successful and happy lives if they are provided with the right health services, education and support. There are programs and organizations that help people with Down syndrome and their families.

In conclusion, Down's disease, or Down syndrome, is a genetic disorder that causes mental retardation and physical characteristics. It can affect various aspects of a person's life, but each person is unique and has their own abilities and interests. There are health services and organizations that can help people with Down syndrome and their families so they can live full and happy lives.

*Down syndrome* is a disease caused by the presence of an extra chromosome in the human karyotype.

Often people with the syndrome develop delayed physical and mental development, but intelligence can be peculiar and is often above average. These people have a characteristic external resemblance - short stature, a stupid appearance with raised eyebrows, bulging eyes and a mouth that extends to the ears. The skin often looks puffy, the fingers are short and wide compared to normal limbs, and the hands are small. The syndrome is characterized by a small nose with a wide bridge, a narrow lower jaw, slightly bifurcated lips, and a short neck. Clothes often hang loose on these people. Tucked fingers and a transverse arrangement of the palms on the hands help them hold objects. They have more difficulty performing precise tasks, such as tying shoes or putting on glasses. Due to some blindness and myopia, they often wear glasses after age 30 or earlier. Epicanthums around the eyes, characteristic of albinism, are almost never found, but there are other types of anomalies in the location of the iris
