One should never confuse bad habits with syndromes.
Bad habits can derive from emotional disorders. They are patterns that develop over a period of time, often brought on by stress, anxiety, boredom, and the inability to effectuate change.
If you fall into a pattern that is labeled a syndrome, examine your behavior and try to slowly change it or you will get sick. The emotional body rules. It must be kept in balance or the physical body will break down.
In some instances you will need to get professional help to determine causes and effect.
The term syndrome derives from the Greek and means literally "run together," as the features do. It is most often used when the reason that the features occur together (the pathophysiology of the syndrome) has not yet been discovered. A familiar syndrome name often continues to be used even after an underlying cause has been found, or when there are a number of different primary causes that all give rise to the same combination of symptoms and signs. Many syndromes are named after the physicians credited with first reporting the association; these are "eponymous" syndromes (see also the list of eponymous diseases, many of which are referred to as "syndromes"). Otherwise, disease features or presumed causes, as well as references to geography, history or poetry, can lend their names to syndromes.
The description of a syndrome usually incudes a number of essential characteristics, which when concurrent lead to the diagnosis of the condition. Frequently these are classified as a combination of typical major symptoms and signs - essential to the diagnosis - together with minor findings, some or all of which may be absent. A formal description may specify the minumum number of major and minor findings respectively, that are required for the diagnosis.
In contrast to the major and minor findings which are typical of the syndrome, there may be an association with other conditions, meaning that in persons with the specified syndrome these associated conditions occur more frequently than would be expected by chance. While the syndrome and the associated conditions may be statistically related, they do not have a clear cause and effect relationship - i.e. there is likely to be a separate underlying problem or risk factor that explains the association. An example would be Down syndrome which has the associated condition of diabetes mellitus. A knowledge of associated conditions would dictate that they are specifically looked for in the management of the syndrome.
