How to Diagnose Sleep Disorders Secondary Causes of Insomnia
As I said in prior segments, insomnia oftenhas a different underlying cause where insomnia merely becomes, sort of, a symptom of thecause. People with obstructive sleep apnea often arrive in a sleep disorders office reportinginsomnia or daytime fatigue. The insomnia is coming from the multiple awakenings thatthey are having during the night due to apneas and hypopneas. It's not truly a case of insomnia.Once all diagnostic tests are performed and reviewed, generally this can be shown to thepatient and a different course of treatment can be taken that rarely has little to dowith actual insomnia. People with depression and bipolar disorder, both treated and untreated,often experience forms of insomnia. It's not
uncommon, in the manic stages of bipolar,for a person to sleep very little or not want to sleep at all. Even once the mania is treated,it's not uncommon for the drugs that get used in that treatment to cause disruptions insleep or cause a change in the quality of sleep. Certain people with schizophrenia andolder atypical antipsychotics will have sleep issues or just feel that they don't sleepas well as others. Again, it's a thing that's hard to differentiate because you don't alwaysknow what a schizophrenic patient is reporting. Even the most lucid and medicated ones stillmay not have a good sense of what's going on at night or why they're sleeping poorly.People with restless leg syndrome, of course,
generally aren't sleeping well even once theyget to sleep because their legs are moving and twitching. They're having issues and theirbodies can't fully relax. So, it's important to ruleout the causes of insomnia. Thyroidissues can be a problem. Women sometimes experience insomnia during pregnancy. It is importantto ruleout these secondary causes of insomnia and treat them before treating a patient primarilywith sedatives and other drugs that can cause physical and psychological dependence. It'sjust more efficient to treat underlying problems and eliminate any sort of dysfunction thatthey're creating in a patient's life.
