Three other classes of medications are also used in the treatment of binge eating disorder: antidepressants, anticonvulsants, and anti-obesity medications. Antidepressant medications of the selective serotonin reuptake inhibitor (SSRI) class such as fluoxetine, fluvoxamine, or sertraline have been found to effectively reduce episodes of binge eating and reduce weight. Similarly, anticonvulsant medications such as topiramate and zonisamide may be able to effectively suppress appetite. The long-term effectiveness of medication for binge eating disorder is currently unknown.

Trials of antidepressants, anticonvulsants, and anti-obesity medications suggest that these medications are superior to placebo in reducing binge eating. Medications are not considered the treatment of choice because psychotherapeutic approaches, such as CBT, are more effective than medications for binge eating disorder. Medications also do not increase the effectiveness of psychotherapy, though some patients may benefit from anticonvulsant and anti-obesity medications, such as Phentermine/topiramate, for weight loss.

As of January 2015, lisdexamfetamine was the only drug approved by the Food and Drug Administration in the United States specifically for the treatment of binge eating.

Cognitive behavioral therapy (CBT) treatment has been demonstrated as a more effective form of treatment for BED than behavioral weight loss programs. 50 percent of BED individuals achieve complete remission from binge eating. CBT has also been shown to be an effective method to address self-image issues and psychiatric comorbidities (e.g., depression) associated with the disorder. Recent reviews have concluded that psychological interventions such as psychotherapy and behavioral interventions are more effective than pharmacological interventions for the treatment of binge eating disorder. There is the 12-step Overeaters Anonymous or Food Addicts in Recovery Anonymous.

Few studies guide the treatment of individuals with OSFED. However, cognitive behavioral therapy (CBT), which focuses on the interplay between thoughts, feelings, and behaviors, has been shown to be the leading evidence-based treatment for the eating disorders of BN and BED. For OSFED, a particular cognitive behavioral treatment can be used called CBT-Enhanced (CBT-E), which was designed to treat all forms of eating disorders. This method focuses not only what is thought to be the central cognitive disturbance in eating disorders (i.e., over-evaluation of eating, shape, and weight), but also on modifying the mechanisms that sustain eating disorder psychopathology, such as perfectionism, core low self-esteem, mood intolerance, and interpersonal difficulties. CBT-E showed effectiveness in two studies (total N = 219) and well maintained over 60-week follow-up periods. CBT-E is not specific to individual types of eating disorders but is based on the concept that common mechanisms are involved in the persistence of atypical eating disorders, AN, and BN.

The five OSFED examples that can be considered eating disorders include atypical AN, BN (of low frequency and/or limited duration), BED (of low frequency and/or limited duration), purging disorder, and NES. Of note, OSFED is not limited to these five examples, and can include individuals with heterogeneous eating disorder presentations (i.e., OSFED-other). Another term, Unspecified Feeding or Eating Disorder (UFED), is used to describe individuals for whom full diagnostic criteria are not met but the reason remains unspecified or the clinician does not have adequate information to make a more definitive diagnosis.

- Atypical Anorexia Nervosa: In atypical AN, individuals meet all of the criteria for AN, with the exception of the weight criterion: the individual's weight remains within or above the normal range, despite significant weight loss.

- Atypical Bulimia Nervosa: In this sub-threshold version of BN, individuals meet all criteria for BN, with the exception of the frequency criterion: binge eating and inappropriate compensatory behaviors occur, on average, less than once a week and/or for fewer than 3 months.

- Binge-eating disorder (of low frequency and/or limited duration): In this sub-threshold version of BED, individuals must meet all criteria for BED, with the exception of the frequency criterion: binge eating occurs, on average, less than once a week and/or for fewer than 3 months.

- Purging Disorder: In purging disorder, purging behavior aimed to influence weight or shape is present, but in the absence of binge eating.

- Night Eating Syndrome: In NES, individuals have recurrent episodes of eating at night, such as eating after awakening from sleep or excess calorie intake after the evening meal. This eating behavior is not culturally acceptable by group norms, such as the occasional late-night munchies after a gathering. NES includes an awareness and recall of the eating, is not better explained by external influences such as changes in the individual's sleep-wake cycle, and causes significant distress and/or impairment of functioning. Though not defined specifically in "DSM-5", research criteria for this diagnosis proposed adding the following criteria (1) the consumption of at least 25% of daily caloric intake after the evening meal and/or (2) evening awakenings with ingestions at least twice per week.

Simple behavioral methods are recommended as initial treatment. Enuresis alarm therapy and medications may be more effective but have potential side effects.

- Motivational therapy in nocturnal enuresis mainly involves parent and child education. Guilt should be allayed by providing facts. Fluids should be restricted 2 hours prior to bed. The child should be encouraged to empty the bladder completely prior to going to bed. Positive reinforcement can be initiated by setting up a diary or chart to monitor progress and establishing a system to reward the child for each night that he or she is dry. The child should participate in morning cleanup as a natural, nonpunitive consequence of wetting. This method is particularly helpful in younger children (<8 years) and will achieve dryness in 15-20% of the patients.

- Waiting: Almost all children will outgrow bedwetting. For this reason, urologists and pediatricians frequently recommend delaying treatment until the child is at least six or seven years old. Physicians may begin treatment earlier if they perceive the condition is damaging the child's self-esteem and/or relationships with family/friends.

- Bedwetting alarms: Physicians also frequently suggest bedwetting alarms which sound a loud tone when they sense moisture. This can help condition the child to wake at the sensation of a full bladder. These alarms are considered effective, with study participants being 13 times more likely to become dry at night. There is a 29% to 69% relapse rate, however, so the treatment may need to be repeated.

- DDAVP (desmopressin) tablets are a synthetic replacement for antidiuretic hormone, the hormone that reduces urine production during sleep. Desmopressin is usually used in the form of desmopressin acetate, DDAVP. Patients taking DDAVP are 4.5 times more likely to stay dry than those taking a placebo. The drug replaces the hormone for that night with no cumulative effect. US drug regulators have banned using desmopressin nasal sprays for treating bedwetting since the oral form is considered safer.

- DDAVP is most efficient in children with nocturnal polyuria (nocturnal urine production greater than 130% of expected bladder capacity for age) and normal bladder reservoir function (maximum voided volume greater than 70% of expected bladder capacity for age). Other children who are likely candidates for desmopressin treatment are those in whom alarm therapy has failed or those considered unlikely to comply with alarm therapy. It can be very useful for summer camp and sleepovers to prevent enuresis.

- Tricyclic antidepressants: Tricyclic antidepressant prescription drugs with anti-muscarinic properties have been proven successful in treating bedwetting, but also have an increased risk of side effects, including death from overdose. These drugs include amitriptyline, imipramine and nortriptyline. Studies find that patients using these drugs are 4.2 times as likely to stay dry as those taking a placebo. The relapse rates after stopping the medicines are close to 50%.

A strict schedule and good sleep hygiene are essential in maintaining any good effects of treatment. With treatment, some people with mild DSPD may sleep and function well with an earlier sleep schedule. Caffeine and other stimulant drugs to keep a person awake during the day may not be necessary, and should be avoided in the afternoon and evening, in accordance with good sleep hygiene. A chief difficulty of treating DSPD is in "maintaining" an earlier schedule after it has been established. Inevitable events of normal life, such as staying up late for a celebration or deadline, or having to stay in bed with an illness, tend to reset the sleeping schedule to its intrinsic late times.

Long-term success rates of treatment have seldom been evaluated. However, experienced clinicians acknowledge that DSPD is extremely difficult to treat. One study of 61 DSPD patients, with average sleep onset at about 3 a.m. and average waking time of about 11:30 a.m., was followed with questionnaires to the subjects after a year. Good effect was seen "during" the six-week treatment with a large daily dose of melatonin. Follow-up showed that over 90% had relapsed to pre-treatment sleeping patterns within the year, 29% reporting that the relapse occurred within one week. The mild cases retained changes significantly longer than the severe cases.

As an alternative to taking prescription drugs, some evidence shows that an average person seeking short-term help may find relief by taking over-the-counter antihistamines such as diphenhydramine or doxylamine. Diphenhydramine and doxylamine are widely used in nonprescription sleep aids. They are the most effective over-the-counter sedatives currently available, at least in much of Europe, and in Canada, Australia, and the United States, and are more sedating than some prescription hypnotics. Antihistamine effectiveness for sleep may decrease over time, and anticholinergic side-effects (such as dry mouth) may also be a drawback with these particular drugs. While addiction does not seem to be an issue with this class of drugs, they can induce dependence and rebound effects upon abrupt cessation of use. However, people whose insomnia is caused by restless legs syndrome may have worsened symptoms with antihistamines.

Drugs that may prove more effective and safer than benzodiazepines for insomnia is an area of active research. Nonbenzodiazepine sedative-hypnotic drugs, such as zolpidem (Ambien), zaleplon, zopiclone (Imovane), and eszopiclone (Lunesta), are a class of hypnotic medications that are similar to benzodiazepines in their mechanism of action, and indicated for mild to moderate insomnia. Their effectiveness at improving time to sleeping is slight, and they have similar—though potentially less severe—side effect profiles compared to benzodiazepines.

Suvorexant is FDA approved for insomnia, characterized by difficulties with sleep onset and/or sleep maintenance.

Prescribing of nonbenzodiazepines has seen a general increase since their initial release on the US market in 1992, from 2.3% in 1993 among individuals with sleep disorders to 13.7% in 2010.

Melatonin taken an hour or so before the usual bedtime may induce sleepiness. Taken this late, it does not, of itself, affect circadian rhythms, but a decrease in exposure to light in the evening is helpful in establishing an earlier pattern. In accordance with its phase response curve (PRC), a very small dose of melatonin can also, or instead, be taken some hours earlier as an aid to resetting the body clock; it must then be small enough not to induce excessive sleepiness.

Side effects of melatonin may include sleep disturbance, nightmares, daytime sleepiness, and depression, though the current tendency to use lower doses has decreased such complaints. Large doses of melatonin can even be counterproductive: Lewy et al. provide support to "the idea that too much melatonin may spill over onto the wrong zone of the melatonin phase-response curve." The long-term effects of melatonin administration have not been examined. In some countries, the hormone is available only by prescription or not at all. In the United States and Canada, melatonin is on the shelf of most pharmacies and herbal stores. The prescription drug Rozerem (ramelteon) is a melatonin analogue that selectively binds to the melatonin MT and MT receptors and, hence, has the possibility of being effective in the treatment of DSPD.

A review by the US Department of Health and Human Services found little difference between melatonin and placebo for most primary and secondary sleep disorders. The one exception, where melatonin is effective, is the "circadian abnormality" DSPD. Another systematic review found inconsistent evidence for the efficacy of melatonin in treating DSPD in adults, and noted that it was difficult to draw conclusions about its efficacy because many recent studies on the subject were uncontrolled.

Modafinil (Provigil) is a stimulant approved in the US for treatment of shift-work sleep disorder, which shares some characteristics with DSPD. A number of clinicians prescribe it for DSPD patients, as it may improve a sleep-deprived patient's ability to function adequately during socially desirable hours. It is generally not recommended to take modafinil after noon; modafinil is a relatively long-acting drug with a half-life of 15 hours, and taking it during the later part of the day can make it harder to fall asleep at bedtime.

Vitamin B was, in the 1990s, suggested as a remedy for DSPD, and is still recommended by some sources. Several case reports were published. However, a review for the American Academy of Sleep Medicine in 2007 concluded that no benefit was seen from this treatment.

Research suggests that hypnosis may be helpful in alleviating some types and manifestations of sleep disorders in some patients. "Acute and chronic insomnia often respond to relaxation and hypnotherapy approaches, along with sleep hygiene instructions." Hypnotherapy has also helped with nightmares and sleep terrors. There are several reports of successful use of hypnotherapy for parasomnias specifically for head and body rocking, bedwetting and sleepwalking.

Hypnotherapy has been studied in the treatment of sleep disorders in both adults and children.

A review of the evidence in 2012 concluded that current research is not rigorous enough to make recommendations around the use of acupuncture for insomnia. The pooled results of two trials on acupuncture showed a moderate likelihood that there may be some improvement to sleep quality for individuals with a diagnosis insomnia. This form of treatment for sleep disorders is generally studied in adults, rather than children. Further research would be needed to study the effects of acupuncture on sleep disorders in children.

There are a number of management options for bedwetting. The following options apply when the bedwetting is not caused by a specifically identifiable medical condition such as a bladder abnormality or diabetes. Treatment is recommended when there is a specific medical condition such as bladder abnormalities, infection, or diabetes. It is also considered when bedwetting may harm the child's self-esteem or relationships with family/friends. Only a small percentage of bedwetting is caused by a specific medical condition, so most treatment is prompted by concern for the child's "emotional" welfare. Behavioral treatment of bedwetting overall tends to show increased self-esteem for children.

Parents become concerned much earlier than doctors. A study in 1980 asked parents and physicians the age that children should stay dry at night. The average parent response was 2.75 years old, while the average physician response was 5.13 years old.

Punishment is not effective and can interfere with treatment.

Possible treatments for circadian rhythm sleep disorders include:

- Behavior therapy or advice about sleep hygiene where the patient is told to avoid naps, caffeine, and other stimulants. They are also told to not be in bed for anything besides sleep and sex.

- Dark therapy, for example the use of blue-blocking goggles, is used to block blue- and bluegreen wavelength light from reaching the eye during evening hours so that the production of melatonin is not decreased or eliminated.

- Medications such as melatonin and modafinil (Provigil), or other short term sleep aids or wake-promoting agents can be beneficial; the former is a natural neurohormone responsible partly and in tiny amounts for the human body clock. The melatonin agonist Tasimelteon, trade name Hetlioz, has been approved in the USA solely for the treatment of non-24-hour sleep–wake disorder in totally blind people.

- Sleep phase chronotherapy may progressively advance or delay sleep time.

Nighttime incontinence may be treated by increasing ADH levels. The hormone can be boosted by a synthetic version known as desmopressin, or DDAVP, which recently became available in pill form. Patients can also spray a mist containing desmopressin into their nostrils. Desmopressin is approved for use by children. There is difficulty in keeping the bed dry after medication is stopped, with as high as an 80% relapse rate.

Another medication, called imipramine, is also used to treat sleepwetting. It acts on both the brain and the urinary bladder. Unfortunately, total dryness with either of the medications available is achieved in only about 20 percent of patients.

If a young person experiences incontinence resulting from an overactive bladder, a doctor might prescribe a medicine that helps to calm the bladder muscle, such as oxybutynin. This medicine controls muscle spasms and belongs to a class of medications called anticholinergics.

Techniques that may help daytime incontinence include:

- Urinating on a schedule, such as every 2 hours (this is called timed voiding)

- Avoiding caffeine or other foods or drinks that may contribute to a child's incontinence

- Following suggestions for healthy urination, such as relaxing muscles and taking your time

RBD is treatable. Medications are prescribed for RBD based on symptoms. Low doses of clonazepam is most effective with a 90% success rate. How this drug works to restore REM atonia is unclear: It is thought to suppress muscle activity, rather than directly restoring atonia. Melatonin is also effective and can also be prescribed as a more natural alternative. For those with Parkinson's and RBD, Levodopa is a popular choice. Pramipexole is another drug which can be an effective treatment option. Recent evidence has shown melatonin and clonazepam to be comparably effective in treatment of RBD with patients who received melatonin treatment reporting fewer side effects. In addition, patients with neurodegenerative diseases such as Parkinson's disease reported more favorable outcomes with melatonin treatment.

In addition to medication, it is wise to secure the sleeper's environment in preparation for episodes by removing potentially dangerous objects from the bedroom and either place a cushion round the bed or moving the mattress to the floor for added protection against injuries. Some extreme sufferers sleep in a sleeping bag zipped up to their neck, and wear mittens so they can't unzip it until they awake in the morning.

Patients are advised to maintain a normal sleep schedule, avoid sleep deprivation, and keep track of any sleepiness they may have. Treatment includes regulating neurologic symptoms and treating any other sleep disorders that might interfere with sleep. Sleep deprivation, alcohol, certain medications, and other sleep disorders can all increase RBD and should be avoided if possible.

Major changes in the management of daytime wetting came about in the 1990s. In most current programs, non-invasive treatments incorporate hydration, timed voiding, correction of constipation and in some cases, computer assisted pelvic floor retraining. These methods have been extremely successful in correcting daytime wetting. Bladder stretching exercises (where the person tries to hold their urine as long as possible) are no longer recommended. In fact, some urologists actually believe that this can be dangerous because the person could develop the long-term habit of tightening the urethral sphincter muscle, which can cause bladder or kidney problems. Urinating on a regular basis is much preferred.

Ruling out infections can also be a part of the differential.

In colder environments where bedding is required to maintain a baby's body temperature, the use of a "baby sleep bag" or "sleep sack" is becoming more popular. This is a soft bag with holes for the baby's arms and head. A zipper allows the bag to be closed around the baby. A study published in the "European Journal of Pediatrics" in August 1998 has shown the protective effects of a sleep sack as reducing the incidence of turning from back to front during sleep, reinforcing putting a baby to sleep on its back for placement into the sleep sack and preventing bedding from coming up over the face which leads to increased temperature and carbon dioxide rebreathing. They conclude in their study, "The use of a sleeping-sack should be particularly promoted for infants with a low birth weight." The American Academy of Pediatrics also recommends them as a type of bedding that warms the baby without covering its head.

Once diagnosed, ASPD can be treated with bright light therapy in the evenings or behaviorally with chronotherapy. Unlike other sleep disorders, ASPD does not disrupt normal functioning at work during the day and the patient does not complain of excessive daytime sleepiness. If their ASPD is causing people to lose out on evening activities, including putting their own typical children to bed, they may be able to force themselves to stay up later than their circadian rhythm requires. A sufferer of ASPD will still wake up very early and if this cycle continues it can lead to chronic sleep deprivation and other sleep disorders.

One of these disorders is extrinsic (from Latin "extrinsecus", from without, on the outside) or circumstantial:

- Shift work sleep disorder, which affects people who work nights or rotating shifts.

Formerly, jet lag, too, was classified as an extrinsic type circadian rhythm disorder.

Sleeping on the back has been found to reduce the risk of SIDS. It is thus recommended by the American Academy of Pediatrics and promoted as a best practice by the US National Institute of Child Health and Human Development (NICHD) "Safe to Sleep" campaign. The incidence of SIDS has fallen in a number of countries in which this recommendation has been widely adopted. Sleeping on the back does not appear to increase the risk of choking even in those with gastroesophageal reflux disease. While infants in this position may sleep more lightly this is not harmful. Sharing the same room as one's parents but in a different bed may decrease the risk by half.

Like other forms of epilepsy, nocturnal epilepsy can be treated with anti-convulsants.

Despite the effectiveness of anti-convulsants in people who suffer from nocturnal epilepsy, the drugs are shown to disrupt a person's sleeping structure. This may cause concern in people who suffer specifically from nocturnal epilepsy because undisrupted sleep is important for these people, as it lowers the likeliness of epileptic symptoms to arise.

One particular study by V. Bradley and D. O'Neill analysed the different forms of epilepsy, including nocturnal epilepsy and its relationship with sleep. They found that some patients only experienced epileptic symptoms while they are asleep (nocturnal epilepsy), and that maintaining good sleep helped in reducing epileptic symptoms. Another study determined that anti-convulsant medications can minimize epilepsy not just in people who are awake, but also in people who are asleep. However, some of these anti-convulsant medications did also have adverse effects on subjects' sleeping structures, which can exacerbate epileptic symptoms in people who suffer from nocturnal epilepsy.

To minimize epileptic seizures in these people, it is important to find an anti-convulsant medication that does not disrupt a person's sleeping structure. The anti-convulsant medications that were tested to meet this criteria are: phenobarbital, phenytoin, carbamazepine, valproate, ethosuximide, felbamate, gabapentin, lamotrigine, topiramate, vigabatrin, tiagabine, levetiracetam, zonisamide, and oxcarbazepine. Oxcarbazepine is shown to have the least amount of adverse effects on sleep. Another study shows that it enhances slow wave-sleep and sleep continuity in patients with epilepsy.

Parasomnias are a category of sleep disorders that involve abnormal movements, behaviors, emotions, perceptions, and dreams that occur while falling asleep, sleeping, between sleep stages, or during arousal from sleep. Most parasomnias are dissociated sleep states which are partial arousals during the transitions between wakefulness and NREM sleep, or wakefulness and REM sleep.

Treatment for paroxysmal nocturnal dyspnea depends on the underlying cause. Options often include oxygen, diuretics, heart medications, antihypertensives, and bronchodilators to reverse wheezing.

ASPD is a rare disorder. It affects both men and women equally and has been determined to have a strong genetic, link with 40–50% of sufferers having relatives with the disorder. As stated below, several genes have been discovered to have links with this syndrome and the body's circadian rhythms. Although it can be impairing, the syndrome is not necessarily unhealthy; most people don't seek help unless it starts to severely impact their social life.
