There are various medical and psychological reasons which can and do invariably bring about sleeping disorders. A sleeping disorder may begin rather unobtrusively with sleep patterns being disrupted only marginally at first. However, if the cause of the disruption is not approached and dealt with sooner rather than later it can become a far more serious problem. In some instances sleeping disorders can also disrupt the everyday workings of a person's physical, mental and emotional activity.
There are many physical conditions which can cause sleeping disorders, such as 'Hypopnea Syndrome' - a condition where the person's respiratory rate becomes abnormally shallow while they are sleeping. Another example is 'Obstructive Sleep Apnea' - which is most commonly due to some kind of obstruction in the airway.

To discover if there are any bio-physiological changes occurring during sleep a Poly-Somno-Graphy (PSG), also referred to as a 'sleep study', might be carried out. A PSG records various functions while the person is sleeping: such as brain and muscle activity, rapid eye movement (which indicates dramatic dreams - night terrors), heart rhythm (ECG) and skeletal-muscle activity (EMG). If more complex data is needed the PSG will either be supplemented or replaced by an Actigraphy. These tests can diagnose which sleeping problem is causing the situation, as well as rule out most of the more common sleeping orders. Insomnia is usually the diagnosis if there is a chronic disruption in sleep patterns occurs and no other cause can be found.
Waking up un-rested and non-responsive can indicate a sleeping disorder and insomnia (defined as the inability to obtain an adequate, good night's sleep, either because of difficulties falling asleep, staying asleep, or both) is indicated. Other commonly diagnosed sleeping disorders include Periodic Limb Movement Disorder (PLMD) and Restless Legs Syndrome (RLS). With PLMD a person will suddenly and involuntarily jerk their arms or legs while sleeping. RLS brings on a slightly different sensation: with RLS the individual feels the irresistible need to move/shake their legs. Often these disorders will be suffered concurrently.
During 2006, the United States Department of Health carried out a study upon one thousand American teens aged 13 to 16 years. Incredibly 11% of them were diagnosed as suffering from Insomnia. In 2007 another study by them revealed that women are almost one and a half times more likely to suffer insomnia and that around 64 million Americans are dealing with this condition every year. That figure alone is enough to cause anyone sleepless nights!
