The Oxford Dictionary defines the word syndrome as “a group of concurrent symptoms of a disease”. This is expanded in the medical field to be a grouping or relationship of a number of medically identifiable characteristics or symptoms that occur together. Oftentimes the detection of one of these symptoms leads to the discovery of others, which can then in turn lead to the diagnosis of a particular syndrome.
A syndrome then is an illness or disorder that has many identifying characteristics or symptoms. Each syndrome (that we know about and have given a name to) has multiple features according to the developmental areas that have been affected by the particular disorder.
