Sleep
Insomnia is a general term for difficulty falling asleep and/or staying asleep. Insomnia is the most common sleep problem, with many adults reporting occasional insomnia, and 10–15% reporting a chronic condition. Insomnia can have many different causes, including psychological stress, a poor sleep environment, an inconsistent sleep schedule, or excessive mental or physical stimulation in the hours before bedtime. Insomnia is often treated through behavioral changes like keeping a regular sleep schedule, avoiding stimulating or stressful activities before bedtime, and cutting down on stimulants such as caffeine. The sleep environment may be improved by installing heavy drapes to shut out all sunlight, and keeping computers, televisions and work materials out of the sleeping area.
Nightmare disorder
Diagnosis and medication can only be given to patients that report the recurring nightmares to a psychiatrist or other physician. Medications like prazosin are sometimes used to treat nightmares in people with PTSD. Therapy usually helps to deal with the frightening themes of the nightmares and alleviate the recurrence of the dreams. The persistent nightmares will usually improve as the patient gets older. Treatments are generally very successful.
