Clinical Information

  • Insomnia is a sleep disorder wherein a patient can’t fall asleep, stay asleep, or both, resulting in the patient having little to no sleep. 
  • There are different types of insomnia depending on how long the patient has the condition. It can be acute, which is short-term, or chronic, which is long-term. 
  • Causes may vary and depend on the type of insomnia the patient has. Causes of acute insomnia are stress from the patient’s relationships, environment, or a traumatic event and substances. Meanwhile, causes of chronic insomnia are changes in work, travel, stress, or feeling upset for an extended period. In some cases, chronic insomnia can also be a side effect or symptom of another condition, disorder, or medication. 
  • Those who are most likely at risk are older adults who are stressed, distressed, working at night, constantly traveling across time zones, aren’t active, or have financial problems. 
  • To diagnose insomnia, a practitioner obtains a patient’s medical and sleep history, does a physical exam, and, if needed, does a sleep study. 
  • Treatment is usually one or a combination of medication, therapy, and lifestyle changes. However, if insomnia is a side effect or symptom, the therapy will be to treat the condition/problem or to change the prescribed medication.
