They can also feel depressed, anxious, and irritable.<\/p>\n<p style=\"text-align: justify;\">The condition thwarts efforts to do well at work and school, as it undermines a person&#8217;s ability to focus, pay attention, remember, and learn.<\/p>\n<p style=\"text-align: justify;\">\n<p style=\"text-align: justify;\">Acute, or short-term, insomnia lasts for a few days or weeks. This\u252c\u00e1<a href=\"https:\/\/www.nhlbi.nih.gov\/health-topics\/insomnia\">often results<\/a>\u252c\u00e1from traumatic events or pressure from family and work situations. Other people have the ongoing or chronic form of insomnia that lasts for months and longer.<\/p>\n<p style=\"text-align: justify;\">While scientists have attempted to study the brain mechanisms of insomnia, their findings have been mostly inconsistent.<\/p>\n<p style=\"text-align: justify;\">There is a similar pattern with treatment effectiveness: it works for some, but not for others.<\/p>\n<p style=\"text-align: justify;\">Blanken and her colleagues suggest that this lack of consistency could be because &#8220;subtypes of this disease remain unrecognized.&#8221;<\/p>\n<h5 style=\"text-align: justify;\"><strong>5 types of insomnia :<\/strong><\/h5>\n<p style=\"text-align: justify;\">So, the researchers decided to investigate further with a study in three parts.<\/p>\n<p style=\"text-align: justify;\">First, they analyzed the results of up to 34 different questionnaires that 4,322 volunteers in the\u252c\u00e1<a href=\"https:\/\/nin.nl\/research\/researchgroups\/van-someren-group\/research-topics\/netherlands-sleep-registry\/\">Netherlands Sleep Registry<\/a>\u252c\u00e1had filled in.<\/p>\n<p style=\"text-align: justify;\">The questionnaires measured personality traits that scientists have linked to differences in brain function and structure.<\/p>\n<p style=\"text-align: justify;\">Using a method called &#8220;latent class analyses&#8221; on the questionnaire data, the researchers identified five types of insomnia, as follows:<\/p>\n<ul style=\"text-align: justify;\">\n<li>Type 1 &#8220;highly distressed&#8221;: Scores high on distressing personality traits, such as\u252c\u00e1<a href=\"https:\/\/www.medicalnewstoday.com\/articles\/246608.php\">neuroticism<\/a>and &#8220;feeling down or tense.&#8221;<\/li>\n<li>Type 2 &#8220;moderately distressed but reward-sensitive&#8221;: Scores indicate that responses to &#8220;pleasurable emotions&#8221; are intact.<\/li>\n<li>Type 3 &#8220;moderately distressed and reward-insensitive.&#8221;<\/li>\n<li>Type 4 &#8220;slightly distressed with high reactivity&#8221;: Insomnia symptoms vary with &#8220;environment and life events.&#8221;<\/li>\n<li>Type 5 &#8220;slightly distressed with low reactivity.&#8221;<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">They then confirmed their findings in the second part of the study by evaluating a &#8220;second, non-overlapping cohort&#8221; of 251 volunteers that they had recruited from new members of the sleep registry.<\/p>\n<p style=\"text-align: justify;\">Finally, 5 years later, in the third part of the study, the team re-evaluated 215 volunteers from the first sample.<\/p>\n<p style=\"text-align: justify;\">These results revealed that individuals had mostly conserved their type of insomnia from 5 years earlier &#8220;indicating a high stability of the classification.&#8221;<\/p>\n<h5 style=\"text-align: justify;\"><strong>Other differences among types of insomnia :<\/strong><\/h5>\n<p style=\"text-align: justify;\">Further examination also uncovered other measurable differences in the five types of insomnia.<\/p>\n<p style=\"text-align: justify;\">For example, electroencephalograms revealed distinct differences in brain responses to external stimuli. This strengthens the idea that brain research might reveal some underlying mechanisms.<\/p>\n<p style=\"text-align: justify;\">The researchers also found that the insomnia types they identified differed in their responses to treatment with drugs and\u252c\u00e1<a href=\"https:\/\/www.medicalnewstoday.com\/articles\/296579.php\">cognitive behavioral therapy<\/a>.<\/p>\n<p style=\"text-align: justify;\"><strong>Also, the risk of developing depression varied widely among the insomnia types. The risk &#8220;was up to five times different between groups,&#8221; note the authors.<\/strong><\/p>\n<p style=\"text-align: justify;\">The researchers have already begun to investigate ways to prevent depression in people with the type of insomnia that carries the highest risk.<\/p>\n<p style=\"text-align: justify;\">They were surprised that the types did not vary on symptom-related factors, such as difficulty getting to sleep as against early waking.<\/p>\n<p style=\"text-align: justify;\">They suggest that earlier studies that have tried to identify insomnia types may have failed because they focused too much on such symptoms.<\/p>\n<blockquote>\n<h4 style=\"text-align: justify;\"><em><strong>Source :Medical News Today<\/strong><\/em><\/h4>\n<\/blockquote>\n<p style=\"text-align: justify;\">\n<p style=\"text-align: justify;\">\n","protected":false},"excerpt":{"rendered":"<p>Published Thursday 17 January 2019 By\u252c\u00e1Catharine Paddock PhD Fact checked\u252c\u00e1by Paula Field There are five types of insomnia, each with its own distinct features, according [&hellip;] <span class=\"read-more-link\"><a class=\"read-more\" href=\"https:\/\/directory.illaaj.com\/blogs\/insomnia-breakthrough-scientists-identify-5-types\/\">Read More<\/a><\/span><\/p>\n","protected":false},"author":3,"featured_media":987,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[20,13],"tags":[],"_links":{"self":[{"href":"https:\/\/directory.illaaj.com\/blogs\/wp-json\/wp\/v2\/posts\/986"}],"collection":[{"href":"https:\/\/directory.illaaj.com\/blogs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/directory.illaaj.com\/blogs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/directory.illaaj.com\/blogs\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/directory.illaaj.com\/blogs\/wp-json\/wp\/v2\/comments?post=986"}],"version-history":[{"count":2,"href":"https:\/\/directory.illaaj.com\/blogs\/wp-json\/wp\/v2\/posts\/986\/revisions"}],"predecessor-version":[{"id":990,"href":"https:\/\/directory.illaaj.com\/blogs\/wp-json\/wp\/v2\/posts\/986\/revisions\/990"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/directory.illaaj.com\/blogs\/wp-json\/wp\/v2\/media\/987"}],"wp:attachment":[{"href":"https:\/\/directory.illaaj.com\/blogs\/wp-json\/wp\/v2\/media?parent=986"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/directory.illaaj.com\/blogs\/wp-json\/wp\/v2\/categories?post=986"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/directory.illaaj.com\/blogs\/wp-json\/wp\/v2\/tags?post=986"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
