How to diagnose Insomnia?
The scale in which insomnia is widely measured is the Athens insomnia scale. The scale measures sleep patter considering eight different parameters related to sleep. The results are tabulated and an overall score is given which represents the sleep quality of the diagnosed patient.
Diagnosis should be done only by a qualified professional of any sleep disorder so the appropriate measures can be taken. The patient's past medical history and a thorough physical examination need to be done so as to eliminate other medical conditions that could be the cause of insomnia.
After the test, when all other conditions are ruled out, a study is done on the sleep history of the patient. The comprehensive sleep history taken should include sleep habits, medications taken by the patient including prescribed and unprescribed. The data will also include the quantities of alcohol consumption, nicotine and caffeine intake and so on. Though the medical conditions are ruled out, the sleep history will take into consideration the recent diseases, injuries or illnesses. The sleeping environment which includes the bedroom, the type of bed, noise at night is also looked into.
How to keep a record of the sleep pattern?
A very beneficial method to tackle insomnia is to keep a record of the sleep pattern. For this, sleep specialists recommend keeping a sleep diary. The diary should include the precise time of going to bed, hours of total sleep time, time taken to fall asleep, number of intermittent awakenings, a history of use of medications both to induce sleep and for curing any other illness. The diary should also mark the time of awakening, and overall opinion of the patient about the quality of sleep.
The sleep pattern can also be recorded by using instruments like Actigraph. This is a non-invasive device that measures movement. The unit is usually in a wrist-watch-like package worn on the wrist. The movements of the actigraph unit undergoes are continually recorded.
Once a comprehensive idea of the sleep pattern is achieved, it is possible to critically analyze and find effective methods to curb the problem. In some cases, simple practices of keeping sleep hygiene will reduce insomnia. But in some others, right medication will have to be taken under the instruction of a medical practitioner.
In some cases, patients may need to do another test to determine insomnia. They would have to do an overnight sleep study to. During the sleep, they will be connected to some devices to measure the quality of sleep including a polysomnogram and the multiple sleep latency test. Specialists in sleep medicine will consider 81 major sleep disorder diagnostic categories and arrive at conclusions. This helps the expert to avoid misdiagnosing the problem.
For instance, patients with some disorders, including delayed sleep phase disorder, are often misdiagnosed with primary insomnia. In the case when a person has trouble on the onset of sleep and they are able to get undisturbed sleep once they start sleeping, the person may not be an insomniac. It can be trouble in the circadian rhythm.
Insomnia can be a side-effect
In many cases, insomnia is co-morbid with some diseases. It can also be due to side-effects from medications, or a psychological problem. It is estimated that almost half of all diagnosed insomnia is related to psychiatric disorders.
In some cases, insomnia predates many psychiatric problems like depression. In fact, it is possible that insomnia represents a significant risk for the development of a subsequent psychiatric disorder. Recent studies prove that 60 % and 80% of people with depression suffer from the problem. Some medical experts are of the opinion that this can be due to treatment used for depression.

Another problem with caffeine is that it will stay in the body for up to eight hours. It is hence better to not consume food or drinks with caffeine before going to bed.
