A syndrome is a collection of symptoms and signs that often occur together and indicate a particular medical condition. These symptoms can affect various parts of the body and may vary in severity from person to person. For example, the Down syndrome is characterized by a combination of physical traits and developmental challenges, which arise from an extra copy of chromosome 21. Syndromes can be caused by genetic factors, environmental influences, or a combination of both. Understanding syndromes helps doctors diagnose and treat patients more effectively. For instance, Asperger syndrome is part of the autism spectrum and affects social interaction and communication skills, highlighting the importance of tailored support for individuals.
