When and who discovered down syndrome

Having first qualified in pharmacy he entered the London Hospital Medical School at the age of 25 where he was a triple gold medallist. Conolly wished to pursue the correlation between the external contours of the skull and specific intellectual and psychological characteristics. Langdon Down began by examining the palates and tongues of the residents and in his report he said "in 16 cases the tongue presented a sodden appearance and exhibited transverse furrows on its dorsal surface; in all these patients one is able to trace a marked physiological and psychological agreement.

So much do they resemble one another that they might readily be taken for members of the same family. Twelve appear to have very large tongues which in most cases interfered with speech. He pursued the project for the identification of skull shapes in several ways. In and in he photographed a large number of patients. Over of his black and white negatives have survived.

In his definitive publication in what he described the ethnic classification of idiots in , he pointed to the physical features of patients whom he described as Caucasian, Ethiopian, Malayan, American Indian and Mongolian. It was the last of these categories which encompassed the first description of what is now known as Down's syndrome.

John Langdon Down, identified the syndrome in He was the first to differentiate the condition as a unique disorder, thereby marking the beginning of Down syndrome evolution in medical studies. The historical medical approaches to Down syndrome reflect a diverse spectrum of perspectives and practices. Regrettably, societal norms and a lack of comprehensive knowledge during certain periods led to misinformation and the stigmatization of individuals with Down syndrome.

In the early 20th century, prevailing attitudes toward intellectual disabilities, including Down syndrome, resulted in the unfortunate institutionalization of affected individuals. This practice not only perpetuated misconceptions but also contributed to their alienation from mainstream society. As the mid-century approached, significant Down syndrome milestones emerged, marking a turning point in how the condition was perceived and addressed.

Increased awareness and evolving medical insights began to challenge the prevailing misrepresentations of Down syndrome. This transformative period laid the foundation for more inclusive approaches to care and education for individuals with Down syndrome, fostering a gradual departure from the previous era of isolation and misunderstanding.

The historical journey of understanding Down syndrome has undergone significant transformations, reflecting both the limitations and progress of medical and societal knowledge. Furthermore, as we delve into the historical advancements in Down syndrome understanding, we uncover a narrative shaped by evolving perspectives, scientific breakthroughs, and the tireless efforts of advocates.

In the early stages, observations of individuals with Down syndrome were often clouded by limited scientific understanding. Prevailing misconceptions perpetuated stereotypes, and individuals with Down syndrome were often isolated or institutionalized due to societal norms and misunderstandings. The lack of comprehensive knowledge hindered the ability to appreciate the full spectrum of capabilities within this community.

The midth century marked a turning point with the emergence of medical insights that challenged prevailing stereotypes. Researchers and clinicians began to unravel the genetic basis of Down syndrome , identifying the presence of an extra copy of chromosome This pivotal discovery laid the foundation for a more nuanced understanding of the condition, steering society away from stigmatization towards a path of increased empathy and awareness.

Parallel to scientific advancements, advocacy movements played a crucial role in shaping public perception. Individuals, families, and organizations dedicated themselves to dispelling myths, promoting inclusivity, and emphasizing the unique strengths of those with Down syndrome. These advocacy efforts brought about a cultural shift, fostering a more compassionate view that focused on abilities rather than limitations.

Translocation Down syndrome: In this type, a part of chromosome 21 breaks off and attaches to another chromosome. This can be inherited, meaning a parent can carry the translocation and have a higher chance of having a child with Down syndrome. Mosaicism is the rarest type, occurring when some cells have three copies of chromosome In comparison, others have the typical two copies.

Individuals with mosaicism may have fewer characteristics of Down syndrome than those with trisomy It is estimated that approximately , individuals in the US are currently living with Down syndrome. Prenatal screening tests during pregnancy can assess the likelihood of a baby having Down syndrome. Diagnostic tests, such as amniocentesis or chorionic villus sampling CVS , can provide a definitive diagnosis.
