Psychotherapy, more specifically, cognitive behavioral therapy (CBT), is the most widely used form of treatment for Somatic symptom disorder. In 2016, a randomized 12-week study suggested steady and significant improvement in health anxiety measures with cognitive behavioral therapy compared to the control group.

CBT can help in some of the following ways:

- Learn to reduce stress

- Learn to cope with physical symptoms

- Learn to deal with depression and other psychological issues

- Improve quality of life

- Reduce preoccupation with symptom

Moreover, brief psychodynamic interpersonal psychotherapy (PIT) for patients with multisomatoform disorder has shown its long-term efficacy for improving the physical quality of life in patients with multiple, difficult-to-treat, medically unexplained symptoms.

Antidepressant medication has also been used to treat some of the symptoms of depression and anxiety that are common among people who have somatic symptom disorder. Medications will not cure somatic symptom disorder, but can help the treatment process when combined with CBT.

Some treatments for internalizing disorders include antidepressants, electroconvulsive therapy, and psychotherapy.

The recommended treatment for adjustment disorder is psychotherapy. The goal of psychotherapy is symptom relief and behavior change. Anxiety may be presented as "a signal from the body" that something in the patient's life needs to change. Treatment allows the patient to put his or her distress or rage into words rather than into destructive actions. Individual therapy can help a person gain the support they need, identify abnormal responses and maximize the use of the individual's strengths. Counseling, psychotherapy, crisis intervention, family therapy, behavioral therapy and self-help group treatment are often used to encourage the verbalization of fears, anxiety, rage, helplessness, and hopelessness. Sometimes small doses of antidepressants and anxiolytics are used in addition to other forms of treatment. In patients with severe life stresses and a significant anxious component, benzodiazepines are used, although non-addictive alternatives have been recommended for patients with current or past heavy alcohol use, because of the greater risk of dependence. Tianeptine, alprazolam, and mianserin were found to be equally effective in patients with AD with anxiety. Additionally, antidepressants, antipsychotics (rarely) and stimulants (for individuals who became extremely withdrawn) have been used in treatment plans.

There has been little systematic research regarding the best way to manage individuals with an adjustment disorder. Because natural recovery is the norm, it has been argued that there is no need to intervene unless levels of risk or distress are high. However, for some individuals treatment may be beneficial. AD sufferers with depressive and/or anxiety symptoms may benefit from treatments usually used for depressive and/or anxiety disorders. One study found that AD sufferers received similar interventions to those with other psychiatric diagnoses, including psychological therapy and medication. Another study found that AD responded better than major depression to antidepressants. Given the absence of a meaningful evidence base for the treatment of AD "per se", watchful waiting should be considered initially; if symptoms are not improving or causing the sufferer marked distress then treatment should be directed at the predominating symptoms.

In addition to professional help, parents and caregivers can help their children with their difficulty adjusting by:

- offering encouragement to talk about his/her emotions

- offering support and understanding

- reassuring the child that their reactions are normal

- involving the child's teachers to check on their progress in school

- letting the child make simple decisions at home, such as what to eat for dinner or what show to watch on TV

- having the child engage in a hobby or activity they enjoy

Despite recent initiatives to study psychopathology along dimensions of behavior and neurobiological indices, which would help refine a clearer picture of the development and treatment of externalizing disorders, the majority of research has examined specific mental disorders. Thus, best practices for many externalizing disorders are disorder-specific. For example, substance use disorders themselves are very heterogeneous and their best-evidenced treatment typically includes cognitive behavioral therapy, motivational interviewing, and a substance disorder-specific detoxification or psychotropic medication treatment component. The best-evidenced treatment for childhood conduct and externalizing problems more broadly, including youth with ADHD, ODD, and CD, is parent management training, a form of cognitive behavioral therapy. Additionally, individuals with ADHD, both youth and adults, are frequently treated with stimulant medications (or alternative psychotropic medications), especially if psychotherapy alone has not been effective in managing symptoms and impairment. Psychotherapy and medication interventions for individuals with severe, adult forms of antisocial behavior, such as antisocial personality disorder, have been mostly ineffective. An individual's comorbid psychopathology may also influences the course of treatment for an individual.

For those patients who have not been able to stop this disorder on their own, doctors have been working to discover a treatment that will work for everyone. One treatment that Schenck and Mahowald studied consisted of psychotherapy combined with "environmental manipulation". This was usually done separately from the weight-reducing diets. However, during this study only 10 percent of the patients were able to lose more than one third of their initial excess weight, which was not a viable percentage. In addition, they reported that many of the patients experienced "major depression" and "severe anxiety" during the attempted treatments. This was not one of the most successful attempts to help those with NSRED.

However, Dr. R. Auger reported on another trial treatment where patients were treated utilizing pramipexole. Those conducting the treatment noticed how the nocturnal median motor activity was decreased, as was assessed by actigraphy, and individual progress of sleep quality was reported. Nevertheless, Augur also said, "27 percent of subjects had RLS (restless legs syndrome, a condition known to respond to this medication), and number and duration of waking episodes related to eating behaviors were unchanged." Encouraged by the positive response verified in the above-mentioned trial treatment, doctors and psychiatrists conducted a more recent study described by Auger as "efficacy of topiramate [an antiepileptic drug associated with weight loss] in 17 consecutive patients with NSRED." Out of the 65 percent of patients who continued to take the medication on a regular basis, all confirmed either considerable development or absolute remission of "night-eating" in addition to "significant weight loss" being achieved. This has been one of the most effective treatments discovered so far, but many patients still suffered from NSRED. Therefore, other treatments were sought after.

Such treatments include those targeted to associated sleep disorders with the hope that it would play an essential part of the treatment process of NSRED. In Schenck and Mahowald's series, combinations of cardibopa/L-dopa, codeine, and clonazepam were used to treat five patients with RLS and one patient with somnambulism and PLMS (periodic limb movements in sleep). These patients all were suffering from NSRED as well as these other disorders, and they all experienced a remission of their NSRED as a result of taking these drugs. Two patients with OSA (obstructive sleep apnea) and NSRED also reported as having a "resolution of their symptoms with nasal continuous positive airway pressure (nCPAP) therapy." Clonazepam monotherapy was also found to be successful in 50 percent of patients with simultaneous somnambulism. Interestingly, dopaminergic agents such as monotherapy were effective in 25 percent of the NSRED subgroup. Success with combinations of dopaminergic and opioid drugs, with the occasional addition of sedatives, also was found in seven patients without associated sleep disorders. In those for whom opioids and sedatives are relatively contraindicated (e.g., in those with histories of substance abuse), two case reports were described as meeting with success with a combination of bupropion, levodopa, and trazodone. Notably, hypnotherapy, psychotherapy, and various behavioral techniques, including environmental manipulation, were not effective on the majority of the patients studied. Nevertheless, Auger argue that behavioral strategies should complement the overall treatment plan and should include deliberate placement of food to avoid indiscriminate wandering, maintenance of a safe sleep environment, and education regarding proper sleep hygiene and stress management. Even with their extensive studies, Schenck and Mahowald did not find the success as Auger found by treating his patients with topiramate.

Western doctors are more likely to diagnose it as a kind of stress or depression. The "Diagnostic and Statistical Manual of Mental Disorders" currently lists "hwabyeong" among its culture-bound illnesses. Outside of Korea, informally "hwabyeong" may be mistaken as a reference to a psychological profile marked by a short temper, or explosive, generally bellicose behavior. To the contrary, "hwabyeong" is a traditional psychological term used to refer to a condition characterized by passive suffering, is roughly comparable to depression, and is typically associated with older women. It is important that when diagnosing Hwabyeong, the culture of the patient is well understood. Since Hwabyeong can often be misdiagnosed as depression, the symptoms and culture need to be clearly and thoroughly looked into. Once Hwabyeong has been diagnosed, past treatments need to be reviewed. The treatments for the patient can then be a combination of pharmacological, and therapy-based interventions.

The treatment methods used to combat hwabyung include psychotherapy, drug treatment, family therapy, and community approaches. To be more successful psychiatrists might need to incorporate the teachings from traditional and religious healing methods or the use of han-puri, which is the sentiment of resolving, loosening, unraveling and appeasing negative emotions with positive ones. One example of hann-puri would be a mother who has suffered from poverty, less education, a violent husband, or a harsh mother-in-law, can be solved many years later by the success of her son for which she had endured hardships and sacrifices.

Treatment for individuals with X-linked thrombocytopenia is typically focused on managing symptoms of the disorder. Splenectomy has been shown to improve platelet counts but also significantly increases the risk of life-threatening infections for patients with XLT. Therefore, these individuals must take antibiotics for the rest of their life to avoid fatal bacteremia. In the event of significant bleeding, platelet transfusions should be administered. Circumcision should be avoided for infant males with XLT due to the risk of bleeding and infection. Regular follow ups to track blood counts should be utilized as well as confirming that any medications, over the counter or prescription, will not interfere with platelet functioning.

Orofaciodigital syndrome type 1 can be treated with reconstructive surgery or the affected parts of the body. Surgery of cleft palate, tongue nodules, additional teeth, accessory frenulae, and orthodontia for malocclusion. Routine treatment for patients with renal disease and seizures may also be necessary. Speech therapy and special education in the later development may also be used as management.

Clonazepam, commonly referred to as Klonopin, has been prescribed as treatment for sexsomnia. This medication is classified as a benzodiazepine and works by acting on the GABA-A receptors present in the central nervous system (CNS). Benzodiazepines open the chloride channels to allow chloride to enter the neuron. The most common use of this medication is for the treatment of anxiety, seizures, panic disorders, and sleep disorders. Anticonvulsant therapy is used to treat sexual behaviors that result secondary to sleep related epilepsy.

For individuals prescribed anti-anxiety medications such as Alprazolam (Xanax), caffeine can introduce further problems by increasing rates of cytotoxicity and cell death by necrosis. This leads to these medications being essentially ruled out as viable treatments for caffeine-induced anxiety. Due to caffeine’s negative interaction with anti-anxiety medications such as benzodiazepines, treatments for caffeine-induced anxiety disorder tend to focus on abstinence from or a reduction of caffeine intake and behavioral therapy. Some doctors may recommend a continuance of caffeine consumption but with the provision that the patient actively takes note of physiological changes that happen after caffeine intake. The goal of this approach is to help patients better understand the effects of caffeine on the body and to distinguish threatening symptoms from normal reactions.

Fluoxetine, an SSRI used by humans under the brand name Prozac, is now prescribed to dogs under the brand name Reconcile. Another study found that dogs who were being treated with both Reconcile and Behavioral Modulation Treatment compared to dogs receiving a placebo and behavioral therapy called Behavior Modulation Treatment, were much more successful at mitigating behaviors related to separation anxiety. After 8 weeks of treatment, 72% of the dogs given fluoxetine displayed fewer adverse behaviors (e.g., excessive salivation, inappropriate urination/defecation) while only 50% of the placebo group had mitigated these behaviors.

In another study conducted in 2015, dogs expressing symptoms of separation anxiety were given fluoxetine tablets and a standard behavior modification plan for two months. Owner interviews, spatial cognitive bias tests, questionnaires and relations between cognitive bias and drug treatment were all taken into consideration. Results showed that the clinical treatment of fluoxetine seemed to produce a shift in cognitive bias in the canine subjects, emphasizing that pharmacological therapy not only can positively affect behavior, but also an animal's psychological state.

Recent research has suggested that hematopoietic stem cell transplantation may be a treatment option for patients with XLT despite associated risks. Other studies have shown that treatment with corticosteroids or intravenous immunoglobulin in any dose or duration may have a beneficial impact on platelet counts, although transiently. Furthermore, research has shown that splenectomy may not be a good treatment option for patients with XLT as it increases the risk of severe infections. This same research showed that patients with XLT have a high overall survival rate but they are at risk for severe life-threatening complications associated with this disorder, such as serious bleeding events and malignancies.

Treatment for sexsomnia involves one or more of the following:

- prescription medications

- CPAP

- lifestyle changes

There are different types of treatments available for mood disorders, such as therapy and medications. Behaviour therapy, cognitive behaviour therapy and interpersonal therapy have all shown to be potentially beneficial in depression. Major depressive disorder medications usually include antidepressants, while bipolar disorder medications can consist of antipsychotics, mood stabilizers, anticonvulsants and/or lithium. Lithium specifically has been proven to reduce suicide and all causes of mortality in people with mood disorders. If mitochondrial dysfunction or mitochondrial diseases are the cause of mood disorders like bipolar disorder, then it has been hypothesized that N-acetyl-cysteine (NAC), acetyl-L-carnitine (ALCAR), S-adenosylmethionine (SAMe), coenzyme Q10 (CoQ10), alpha-lipoic acid (ALA), creatine monohydrate (CM), and melatonin could be potential treatment options.

Dogs can also be treated with psychotropic drugs, such as anti-depressants or anti-anxiety drugs.

A recent trend in treatment is the use of psychotropic drugs in animals to treat similar psychological disorders to those displayed in humans and mitigate the behavior related to these disorders. These connections between human and animal psychopharmacology can help to explain how similar neurobiology can be among different species.

Similar to humans, Selective Serotonin Reuptake Inhibitors, or SSRIs, or tricyclic anti-depressants are used to treat anxious and depressive behavior in animals. One study tracked the effectiveness of clomipramine, a tricyclic anti-depressant, in reducing compulsive behaviors through administration of a tricyclic anti-depressant in dogs. Behaviors displayed by these dogs include but are not limited to tail-chasing, shadow-chasing, circling and chewing. The study found that after one month of daily administration of the tricyclic anti-depressant clomipramine, these compulsive behaviors decreased or disappeared in 16 out of 24 dogs. Slight to moderate behavior mitigation was shown in 5 dogs. These results suggest that clomipramine can be beneficial to canines displaying anxiety behaviors.

Anxiety disorders can also be treated with dog-appeasing pheromones similar to those given off by their mothers. The pheromone containing products are sold in collars and sprays under the brand name Adaptil.

Unlike other autoinflammatory disorders, patients with CANDLE do not respond to IL-1 inhibition treatment in order to stop the autoinflammatory response altogether. This suggests that the condition also involves IFN dysregulation.

Bisphosphonate therapy has been suggested as a first-line therapeutic option in many case reports and series.

Treatment with tumor necrosis factor alpha antagonists (TNF inhibitors) have been tried in few patients with limited success. Other drugs that are used in psoriatic arthritis, to which SAPHO syndrome is closely related, have also been used in this condition. They include NSAIDs, corticosteroids, sulfasalazine, methotrexate, ciclosporin and leflunomide.

Some patients have responded to antibiotics. The rationale for their use is that Propionibacterium acnes, a bacterium known for its role in acne, has been isolated from bone biopsies of SAPHO patients.

Metabolic disorders can be treatable by nutrition management, especially if detected early. It is important for dieticians to have knowledge of the genotype to therefore create a treatment that will be more effective for the individual.

Medication is often not necessary in children as symptoms usually alleviate spontaneously as the child ages. However, because the disorder may affect wakeful behavior, many adults who continue to suffer from RMD may seek treatment. Benzodiazepines or tricyclic antidepressants have been considered as therapeutic options in managing the disorder. Infantile and adolescent RMD respond well to low doses of clonazepam. Prescription medications such as ropinirole or pramipexole given to restless legs syndrome patients do not show any clinical improvement in many patients with RMD.

Treatment of sleep apnea via a continuous positive airway pressure (CPAP) device has shown dramatic improvement in apnea and nearly complete resolution of RMD symptoms. Behavioral interventions may alleviate some RMD symptoms and movements. In such a therapy, sufferers are asked to perform RMD-like motions during the day in a slow and methodic manner. In such, patients come short of full rhythmic movements that they experience in sleep. Such behavioral training has been shown to carry over into sleep, and the forcefulness of the RMD movements is reduced or eliminated. Hypnosis and sleep restriction have been used in some cases to good effect.

There are numerous ways in which individuals can reduce emotional distress without engaging in emotional eating. The most salient choice is to minimize maladaptive coping strategies and to maximize adaptive strategies. A study conducted by Corstorphine et al. in 2007 investigated the relationship between distress tolerance and disordered eating. These researchers specifically focused on how different coping strategies impact distress tolerance and disordered eating. They found that individuals who engage in disordered eating often employ emotional avoidance strategies. If an individual is faced with strong negative emotions, they may choose to avoid the situation by distracting themselves through overeating. Discouraging emotional avoidance is thus an important facet to emotional eating treatment. The most obvious way to limit emotional avoidance is to confront the issue through techniques like problem solving. Corstorphine et al. showed that individuals who engaged in problem solving strategies enhance one's ability to tolerate emotional distress. Since emotional distress is correlated to emotional eating, the ability to better manage one's negative affect should allow an individual to cope with a situation without resorting to overeating.

One way to combat emotional eating is to employ mindfulness techniques. For example, approaching cravings with a nonjudgmental inquisitiveness can help differentiate between hunger and emotionally-driven cravings. An individual may ask his or herself if the craving developed rapidly, as emotional eating tends to be triggered spontaneously. An individual may also take the time to note his or her bodily sensations, such as hunger pangs, and coinciding emotions, like guilt or shame, in order to make conscious decisions to avoid emotional eating.

Emotional eating disorder predisposes individuals to more serious eating disorders and physiological complications. Therefore, combatting disordered eating before such progression takes place has become the focus of many clinical psychologists.

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.

A number of medications have been approved for the treatment of substance abuse. These include replacement therapies such as buprenorphine and methadone as well as antagonist medications like disulfiram and naltrexone in either short acting, or the newer long acting form. Several other medications, often ones originally used in other contexts, have also been shown to be effective including bupropion and modafinil. Methadone and buprenorphine are sometimes used to treat opiate addiction. These drugs are used as substitutes for other opioids and still cause withdrawal symptoms.

Antipsychotic medications have not been found to be useful. Acamprostate is a glutamatergic NMDA antagonist, which helps with alcohol withdrawal symptoms because alcohol withdrawal is associated with a hyperglutamatergic system.

Psychedelics, such as LSD and psilocin, may have anti-addictive properties.

Lip pits may be surgically removed either for aesthetic reasons or discomfort due to inflammation caused by bacterial infections or chronic saliva excretion, though spontaneous shrinkage of the lip pits has occurred in some rare cases. Chronic inflammation has also been reported to cause squamous-cell carcinoma. It is essential to completely remove the entire lip pit canal, as mucoid cysts can develop if mucous glands are not removed. A possible side effect of removing the lip pits is a loose lip muscle. Other conditions associated with VWS, including CL, CP, congenital heart defects, etc. are surgically corrected or otherwise treated as they would be if they were non-syndromic.
