What is nightmare disorder?

Nightmare disorder is a type of sleeping disorder that is characterised by recurring, vivid, and often quite distressing dreams that can cause an individual to wake up all of a sudden.³ Consequently, this can lead to affected individuals feeling drained, anxious, and on edge during the day, making it hard to focus or enjoy things. This sleeping disorder affects approximately 2% to 6% of adults, with higher prevalence among individuals with post-traumatic stress disorder (PTSD), depression, or anxiety.¹ 

These nightmares typically occur during rapid eye movement (REM) sleep and are often remembered when the person wakes up due to their distressing nature. The REM stage of sleep is the stage of sleep when most vivid dreaming occurs. The REM stage of sleep is when we do most of our vivid dreaming. During this time, the brain is active, but the body stays temporarily paralysed, so we don’t act out our dreams.² Chronic nightmare disorder is associated with increased risks of suicide attempts and exacerbation of underlying mental health issues.⁵

This article explores the prognosis and long-term outlook for nightmare disorder, answering the question of whether it can be cured altogether or if individuals will have to settle for management of symptoms through various types of treatment. 

Prognosis: Can nightmare disorder be cured?

The prognosis for nightmare disorder varies among individuals. For some, especially those with recurring bad dreams that happen without any clear cause, the condition may resolve on its own or with minimal intervention. However, for others, such as those with psychiatric conditions, the nightmares can continue for years or even decades if left untreated.⁴ Nightmare disorder usually can't be "cured" in the traditional sense, but it can often be managed very effectively with the right treatment plans. For many people, symptoms can significantly improve or even go away with consistent treatment.

Treatment modalities

Effective management of nightmare disorder involves a combination of behavioral therapies and pharmacological interventions. The choice of treatment depends on the underlying cause, the severity of the disease, and individual patient medical history.

Types of behavioral therapies

Imagery rehearsal therapy (IRT)

IRT is a cognitive-behavioural technique that involves thinking about the nightmare, changing it to something less scary or more positive, and then practising the new version during the day.⁷ Research shows that IRT can help to cut down on nightmare frequency and how intense they are when they happen, in both PTSD-related and idiopathic cases.⁶

Exposure, relaxation, and rescripting therapy (ERRT)

ERRT combines elements of exposure therapy, relaxation techniques, and cognitive restructuring to help people face and change their nightmares. It's been shown to be effective in lowering how often nightmares happen and how upsetting they feel.⁸

Lucid dreaming therapy

This technique trains individuals to become aware that they are dreaming during a nightmare, allowing them to exert control over the dream content.⁹ While promising, more research is needed to establish its long-term effectiveness.

Cognitive behavioural therapy (CBT) 

Cognitive behavioural therapy (CBT) is a widely used and effective approach for treating nightmare disorder. It helps individuals identify and modify unhelpful thoughts and behaviours that contribute to their nightmares. Research suggests that CBT is effective in improving sleep quality and reducing nightmare-related distress.¹⁰

Pharmacological interventions

Prazosin

This is a medication originally used for high blood pressure, but has been looked into a lot for treating nightmares—especially in people with PTSD. It works by blocking certain stress-related signals in the brain, which seems to help calm down the intense emotions that fuel the nightmares.¹¹ Some people see a big difference when they take it, sleeping better and having fewer disturbing dreams, but the results aren’t the same for everyone.¹²

Antidepressants and antipsychotics 

Certain antidepressants, such as SSRIs or tricyclics, can reduce REM sleep—the stage where most nightmares occur. This could help to lower the frequency of nightmares. Antipsychotics like quetiapine have also been suggested for their sedative and mood-stabilising effects.⁴ However, the evidence supporting these medications is mixed, and they can often cause side effects. They’re usually considered when other treatments like therapy haven’t worked, and always under close supervision from a healthcare provider.

Benzodiazepines 

Benzodiazepines, like clonazepam or lorazepam, work by calming down the brain's activity through enhancing the effects of GABA, a neurotransmitter that promotes relaxation and sleep. In the context of nightmare disorder, they may help by reducing anxiety, improving sleep quality, and suppressing REM sleep—the stage where nightmares usually occur. However, they’re not typically a first-line treatment because they can lead to dependence and may disrupt healthy sleep patterns in the long run. They're generally used short-term or in specific cases where other treatments haven’t been effective.¹³

Long-term management and outlook

While some individuals may experience complete remission of nightmares, many require ongoing management to maintain improvements. Long-term strategies include:

Continued behavioural therapy 

Regular sessions can help reinforce coping mechanisms and prevent any relapse.⁶

Medication management 

For those benefiting from pharmacological treatments, ongoing evaluation is often implemented to monitor any side effects and check their efficiency.¹³

Addressing comorbid conditions 

Effective treatment of underlying psychiatric conditions can significantly alleviate nightmare symptoms.¹⁴

Lifestyle modifications 

Maintaining good sleep hygiene, reducing stress, and avoiding substances that could disrupt sleep can aid in reducing the frequency and severity of nightmares.¹⁵

FAQs

Who is most at risk of developing nightmare disorder?

People with PTSD, anxiety, or depression are at higher risk of developing nightmare disorder. However, children, chronically stressed people, or those who’ve recently experienced a traumatic event can also develop the condition even if they have not yet been formally diagnosed with a mental disorder.³

Can nightmare disorder go away on its own?

In some cases, especially when nightmares aren’t linked to an underlying medical condition, they may fade without any sort of formal treatment. However, if the nightmares continue or get worse, professional help is often needed to prevent long-term impact on sleep and mental health. If left untreated, it can lead to sleep avoidance or the development of other sleep disorders.⁷

Are there any warning signs that nightmare disorder is getting worse?

The warning signs can include more frequent nightmares, trouble falling or staying asleep due to fear, increased anxiety or irritability during the day, and a noticeable decline in your mood or performance at work or school. Sleepwalking or nighttime panic may also occur in some cases.¹⁴

Is it safe to combine medication and therapy for treatment?

Yes, many personalised treatment plans use a combination approach. For example, someone might use therapy like IRT or CBT whilst also taking medication such as prazosin. A healthcare provider will tailor the plan to balance effectiveness with safety to make sure there are minimal side effects. Combining approaches may also help to address both the psychological and physiological triggers.¹³

What role does sleep hygiene play in managing nightmare disorder?

Sticking to a regular sleep schedule, avoiding caffeine and screen time before bed, and creating a calming bedtime routine can make a huge difference in reducing nightmare frequency and improving sleep quality. Relaxation techniques like meditation or breathing exercises before sleep can also be quite useful.

Can children develop nightmare disorder, and is the treatment different?

Yes, children can experience nightmare disorder. Treatment is often similar—using therapy and sleep routine adjustment, but is tailored to be age-appropriate and may involve more parental involvement. Parents can be involved in encouraging open conversations about fears and establishing a set bedtime for children.

Summary

Nightmare disorder can be a difficult disorder to manage, and its effects can vary greatly between individuals. Some people may eventually stop experiencing nightmares altogether, but many individuals will need ongoing therapy to bring about long-lasting reduction of symptoms. Treatment is usually a combination of behavioural therapies, medications, and changes to lifestyle habits, designed for and with each individual. Since nightmares can lead to negative effects on sleep, mood, and daily functioning, it is essential to recognise nightmare disorder as soon as possible and create a comprehensive and individualised treatment plan for a better long-term outlook. With good care, most people can see real improvement early and enjoy a better quality of life.
