Public health and insomnia: economic impact.
There seems to be a lack of understanding between practitioners and patients on the topic of insomnia. One adult out of four complains of insomnia; however only one insomniac out of four has ever complained about it to their practitioner during a visit made for another problem and only one out of twenty has come to discuss specifically the problem of his or her insomnia. Only a few patients with insomnia take a treatment for it. This gap between the patient's feeling and the practitioner's answer has to be better understood if we want to know why insomnia seems to be so prevalent and what impact it has on society. One aspect may be a question of definition. Insomnia may be considered an ordinary complaint (after one poor night) or as a chronic disease. Practitioners have poor knowledge about sleep disorders and may be embarrassed about coping with an impairment they never specifically learned to manage. The second aspect concerns the impact of insomnia on daytime alertness and performance. While patients usually complain of an impaired daytime functioning with a feeling of fatigue, sleepiness, and risk of mistakes, many studies of insomniacs do not reveal any increased sleepiness or decrease of performance (measured by objective tests) the day following a poor night. Practitioners may therefore find it difficult to understand the real impact of insomnia on daytime functioning. The third aspect is related to the large co-morbidity between insomnia and psychiatric diseases, especially depression and anxiety. It does make it harder for practitioners to define whether the sleep impairment suffered by their patient is the cause for other symptoms or the consequence of an underlying disease. Thus, it makes it all the more difficult for the practitioner to determine which treatment is the most appropriate. These aspects have to be clarified if one wants to estimate the real impact of insomnia on society. It could be useful to both practitioners and patients to have a better understanding on the relationship between poor sleep and daily lives.
