It is ethically difficult when it comes to dealing with diagnosed patients, for many of them deny their poor conditions and refuse to accept treatment. The main objectives of the doctors are to help improve the patient’s lifestyle and wellbeing, so health care professionals must decide whether or not to force treatment onto their patient.

In some cases, especially those including the inability to move, patients have to consent to help, since they cannot manage to look after themselves. Hospitals or nursing homes are often considered the best treatment under those conditions.

When under care, patients must be treated in a way in which they can learn to trust the health care professionals. In order to do this, the patients should be restricted in the number of visitors they are allowed, and be limited to 1 nurse or social worker. Some patients respond better to psychotherapy, while others to behavioral treatment or terminal care.

Results after hospitalization tend to be poor. Research on the mortality rate during hospitalization has shown that approximately half the patients die while in the hospital. A quarter of the patients are sent back home, while the other quarter are placed in long time care. Patients under care in hospitals and nursing homes often slide back into relapse or face death.

There are other approaches to improve the patient’s condition. Day care facilities have often been successful with maturing the patient’s physical and emotional state, as well as helping them with socialization. Other methods include services inside the patient’s home, such as the delivery of food.

Most current treatments for aboulia are pharmacological, including the use of antidepressants. However, antidepressant treatment is not always successful and this has opened the door to alternative methods of treatment. The first step to successful treatment of aboulia, or any other DDM, is a preliminary evaluation of the patient's general medical condition and fixing the problems that can be fixed easily. This may mean controlling seizures or headaches, arranging physical or cognitive rehabilitation for cognitive and sensorimotor loss, or ensuring optimal hearing, vision, and speech. These elementary steps also increase motivation because improved physical status may enhance functional capacity, drive, and energy and thereby increase the patient's expectation that initiative and effort will be successful.

There are 5 steps to pharmacological treatment:

1. Optimize medical status.

2. Diagnose and treat other conditions more specifically associated with diminished motivation (e.g., apathetic hyperthyroidism, Parkinson's disease).

3. Eliminate or reduce doses of psychotropics and other agents that aggravate motivational loss (e.g., SSRIs, dopamine antagonists).

4. Treat depression efficaciously when both DDM and depression are present.

5. Increase motivation through use of stimulants, dopamine agonists, or other agents such as cholinesterase inhibitors.

"Early onset schizophrenia" (EOS) is not childhood schizophrenia, because this term is used to identify adolescence patients who develop first episode of psychosis before the age of 18. Childhood schizophrenia manifests before the age of 13, so it's correct names are "childhood-onset schizophrenia" (COS) and "very early-onset schizophrenia" (VEOS).

Adolescents (teenagers) are persons between the ages of 13 and 18. Children are defined as persons under the age of 13, so the term "early onset schizophrenia" (EOS) is not not appropriate in the article about childhood schizophrenia.

Cognitive-behavioural therapy (CBT) is a frequently suggested treatment for executive dysfunction, but has shown limited effectiveness. However, a study of CBT in a group rehabilitation setting showed a significant increase in positive treatment outcome compared with individual therapy. Patients' self-reported symptoms on 16 different ADHD/executive-related items were reduced following the treatment period.

As it has already been mentioned, patients with organic personality disorder show a wide variety of sudden behavioural changes and dysfunctions. There are not a lot of information about the treatment of this mental health disorder. The pharmacological approach is the most common therapy among patients with organic personality disorder. However, the choice of drug therapy relies on the seriousness of patient's situation and what symptoms are shown. The choice and administration of specific drugs contribute to the reduction of symptoms of organic personality disorder. For this reason, it is crucial for patients' treatment to be assessed by clinical psychologists and psychiatrists before the administration of drug.

Additionally, the dysfunctions in expression of behaviour of patients with organic personality disorder and the development of symptom of irritability, which are caused by aggressive and self-injurious behaviours, can be dealt with the administration of carbamazepine. Moreover, the symptoms of this disorder can be decreased by the administration of valproic acid. Also, emotional irritability and signs of depression can be dealt with the use of nortriptyline and low-dose thioridazine. Except from the symptom of irritability, patients express aggressive behaviours. At the onset of drug therapy for effective treatment of anger and aggression, the drug of carbamazepine, phenobarbital, benztropine and haloperidol can be administrated in order to reduce the symptoms of patients with organic personality disorder. In addition, the use of propranolol may decrease the frequent behaviours of rage attacks.

Finally, it is important for patients to take part in psychotherapy sessions during the period of drug therapy. In this way, there is prevention and patients can be protected by negative effects of drugs on their organism and their behaviour. Furthermore, the clinicians can provide useful and helpful support to patients during these psychotherapy sessions. Thus, the combination of drug therapy with psychotherapy can lead to the reduction of symptoms of this disorder and the improvement of patients' situation.

Although medication is the first-line treatment for most psychiatric disorders, it does not always improve every aspect of a patient's life, and for the negative symptoms in schizophrenia, the responses to anti-psychotics are less favourable than for positive symptoms. As a result, psychotherapy might be an alternative for the treatment of these symptoms, even if medication has a good effect on other manifestations of the disorder.

Cognitive behavioural therapy (CBT), is the kind of psychotherapy that shows most promise in treating avolition (and other negative symptoms of schizophrenia), but more research is needed in the area. CBT focuses on understanding how thoughts and feelings influence behaviour, in order to help individuals develop methods and strategies to better handle the implications of their disorder. Some research suggests that CBT focusing on social skills and practice of interpersonal situations, like job interviews, seeing a doctor (to discuss medication, for example), or interacting with friends and co-workers, as well as seemingly simple things like riding a bus, might reduce negative symptoms of schizophrenia and be beneficial to patients with avolition.

Other forms of psychotherapy might also complement the role of medication and help patients, their families, and friends to work through emotional and other challenges of living with a chronic psychological disorder, including avolition.

The current treatments for CCAS focus on relieving the symptoms. One treatment is a cognitive-behavioral therapy (CBT) technique that involves making the patient aware of his or hers cognitive problems. For example, many CCAS patients struggle with multitasking. With CBT, the patient would have to be aware of this problem and focus on just one task at a time. This technique is also used to relieve some motor symptoms. In a case study with a patient who had a stroke and developed CCAS, improvements in mental function and attention were achieved through reality orientation therapy and attention process training. Reality orientation therapy consists of continually exposing the patient to stimuli of past events, such as photos. Attention process training consists of visual and auditory tasks that have been shown to improve attention. The patient struggled in applying these skills to “real-life” situations. It was the help of his family at home that significantly helped him regain his ability to perform activities of daily living. The family would motivate the patient to perform basic tasks and made a regular schedule for him to follow.

Transcranial magnetic stimulation (TMS) has also been proposed to be a possible treatment of psychiatric disorders of the cerebellum. One study used TMS on the vermis of patients with schizophrenia. After stimulation, the patients showed increased happiness, alertness and energy, and decreased sadness. Neuropsychological testing post-stimulation showed improvements in working memory, attention, and visual spatial skill. Another possible method of treatment for CCAS is doing exercises that are used to relieve the motor symptoms. These physical exercises have been shown to also help with the cognitive symptoms.

Medications that help relieve deficits in traumatic brain injuries in adults have been proposed as candidates to treat CCAS. Bromocriptine, a direct D2 agonist, has been shown to help with deficits in executive function and spatial learning abilities. Methylphendiate has been shown to help with deficits in attention and inhibition. Neither of these drugs has yet been tested on a CCAS population. It may also be that some of the symptoms of CCAS improve over time without any formal treatment. In the original report of CCAS, four patients with CCAS were re-examined one to nine months after their initial neuropsychological evaluation. Three of the patients showed improvement in deficits without any kind of formal treatment, though executive function was still found to be one standard deviation below average. In one patient, the deficits worsened over time. This patient had cerebellar atrophy and worsened in visual spatial abilities, concept formation, and verbal memory. It should be noted that none of these treatments were tested on a large enough sample to determine if they would help with the general CCAS population. Further research needs to be done on treatments for CCAS.

Reduced affect display, sometimes referred to as emotional blunting, is a condition of reduced emotional reactivity in an individual. It manifests as a failure to express feelings (affect display) either verbally or non-verbally, especially when talking about issues that would normally be expected to engage the emotions. Expressive gestures are rare and there is little animation in facial expression or vocal inflection. Reduced affect can be symptomatic of autism, schizophrenia, depression, posttraumatic stress disorder, depersonalization disorder, schizoid personality disorder or brain damage. It may also be a side effect of certain medications (e.g., antipsychotics and antidepressants). Individuals with blunted or flat affect show different regional brain activity when compared with typical individuals.

Reduced affect should be distinguished from apathy, which explicitly refers to a lack of emotion, whereas reduced affect is a lack of emotional expression regardless of whether emotion is actually reduced or not.

Klüver–Bucy syndrome is a syndrome resulting from bilateral lesions of the medial temporal lobe (including amygdaloid nucleus). Klüver–Bucy syndrome may present with compulsive eating, hypersexuality, insertion of inappropriate objects in the mouth (hyperorality), visual agnosia, and .

Current methods in treating early-onset schizophrenia follow a similar approach to the treatment of adult schizophrenia. Although modes of treatment in this population is largely understudied, the use of antipsychotic medication is commonly the first line of treatment in addressing symptoms. Recent literature has failed to determine if typical or atypical antipsychotics are most effective in reducing symptoms and improving outcomes. When weighing treatment options, it is necessary to consider the adverse effects of various medications used to treat schizophrenia and the potential implications of these effects on development. A 2013 systematic review compared the efficacy of atypical antipsychotics versus typical antipsychotics for adolescents:

Madaan et al. wrote that studies report efficacy of typical neuroleptics such as thioridazine, thiothixene, loxapine and haloperidol, high incidence of side effects such as extrapyramidal symptoms, akathisia, dystonias, sedation, elevated prolactin, tardive dyskinesia.

A Japanese man, who was being treated for schizophrenia, exhibited neuroleptics-induced deficit syndrome and obsessive–compulsive symptoms. His symptoms were remarkably improved by quitting a course of antipsychotics followed by the introduction of the antidepressant fluvoxamine. He has been misdiagnosed with schizophrenia, the real diagnosis was obsessive–compulsive disorder.

In terms of treatment for frontal lobe disorder, general supportive care is given, also some level of supervision could be needed. The prognosis will depend on the cause of the disorder, of course. A possible complication is that individuals with severe injuries may be disabled, such that, a caregiver may be unrecognizable to the person.

Another aspect of treatment of frontal lobe disorder is speech therapy. This type of therapy might help individuals with symptoms that are associated with aphasia and dysarthria.

The most effective method of preventing Korsakoff's syndrome is to avoid B vitamin/thiamine deficiency. In Western nations, the most common causes of such a deficiency are alcoholism and eating disorders. Because these are behavioral-induced causes, Korsakoff's syndrome is essentially considered a preventable disease. Thus, fortifying foods with thiamine, or requiring companies that sell alcoholic beverages to supplement them with B vitamins in general or thiamine in particular, could avert many cases of Korsakoff's Syndrome.

There is much research that needs to be conducted on CCAS. A necessity for future research is to conduct more longitudinal studies in order to determine the long-term effects of CCAS. One way this can be done is by studying cerebellar hemorrhage that occurs during infancy. This would allow CCAS to be studied over a long period to see how CCAS affects development. It may be of interest to researchers to conduct more research on children with CCAS, as the survival rate of children with tumors in the cerebellum is increasing. Hopefully future research will bring new insights on CCAS and develop better treatments.

Aboulia or abulia (from , meaning "will", with the prefix -a), in neurology, refers to a lack of will or initiative and can be seen as a disorder of diminished motivation (DDM). Aboulia falls in the middle of the spectrum of diminished motivation, with apathy being less extreme and akinetic mutism being more extreme than aboulia. A patient with aboulia is unable to act or make decisions independently. It may range in severity from subtle to overwhelming. It is also known as Blocq's disease (which also refers to abasia and astasia-abasia). Aboulia was originally considered to be a disorder of the will.

Klüver–Bucy syndrome was first documented among certain humans who had experienced temporal lobectomy in 1955 by H. Terzian and G.D. Ore. It was first noted in a human with meningoencephalitis in 1975 by Marlowe et al. Klüver–Bucy syndrome can manifest after either of these (lobectomies can be medically required by such reasons as accidents or tumors), but may also appear in humans with acute herpes simplex encephalitis or following a stroke. Other conditions may also contribute to a diagnosis of Klüver–Bucy syndrome, including Pick Disease, Alzheimer's Disease, ischemia, anoxia, progressive subcortical gliosis, Rett syndrome, porphyria and carbon monoxide poisoning, among others.

It is rare for humans to manifest all of the identified symptoms of the syndrome; three or more are required for diagnosis. Among humans, the most common symptoms include placidity, hyperorality and dietary changes. They may also present with an inability to recognize objects or inability to recognize faces or other memory disorders. Social neurosciences research shows that changes in temporal lobe is identified as a cause for aberrant sexual and hyper-sexual behaviors.

Diogenes syndrome, also known as senile squalor syndrome, is a disorder characterized by extreme self-neglect, domestic squalor, social withdrawal, apathy, compulsive hoarding of garbage or animals, and lack of shame. Sufferers may also display symptoms of catatonia.

The condition was first recognized in 1966 and designated Diogenes syndrome by Clark et al. The name derives from Diogenes of Sinope, an ancient Greek philosopher, a Cynic and an ultimate minimalist, who allegedly lived in a large jar in Athens. Not only did he not hoard, but he actually sought human company by venturing daily to the Agora. Therefore, this eponym is considered to be a misnomer, but he is actually a representative existence of self-neglect. Other possible terms are "senile breakdown", "Plyushkin's Syndrome" (after a character from Gogol's novel "Dead Souls"), "social breakdown" and "senile squalor syndrome". Frontal lobe impairment may play a part in the causation (Orrell et al., 1989).

Often, apathy is felt after witnessing horrific acts, such as the killing or maiming of people during a war, e.g. posttraumatic stress disorder. It is also known to be a distinct psychiatric syndrome that is associated with many conditions, some of which are: CADASIL syndrome, depression, Alzheimer's disease, Chagas disease, Creutzfeldt–Jakob disease, dementia (and dementias such as Alzheimer's disease, vascular dementia, and frontotemporal dementia), Korsakoff's syndrome, excessive vitamin D, hypothyroidism, hyperthyroidism, general fatigue, Huntington's disease, Pick's disease, progressive supranuclear palsy (PSP), brain damage, schizophrenia, schizoid personality disorder, bipolar disorder, autism, ADHD, Asperger's syndrome, and others. Some medications and the heavy use of drugs such as opiates or GABA-ergic drugs may bring apathy as a side effect.

Neuroleptic-induced deficit syndrome (NIDS) is a psychopathological syndrome that develops in some patients who take high doses of an antipsychotic for an extended time. It is most often caused by high-potency typical antipsychotics, but can also be caused by high doses of many atypicals, especially those closer in profile to typical ones (that have higher D dopamine receptor affinity and relatively low 5-HT serotonin receptor binding affinity), like risperidone and amisulpride.

Implications from avolition often result in social deficits. Not being able to initiate and perform purposeful activities can have many implications for a person with avolition. By disrupting interactions with both familiar and unfamiliar people, it jeopardizes the patient's social relations. When part of a severe mental illness, avolition has been reported, in first person accounts, to lead to physical and mental inability to both initiate and maintain relationships, as well as work, eat, drink or even sleep.

Clinically, it may be difficult to engage an individual experiencing avolition in active participation of psychotherapy. Patients are also faced with the stresses of coping with and accepting a mental illness and the stigma that often accompanies such a diagnosis and its symptoms. Regarding schizophrenia, the American Psychiatric Association reported in 2013 that there currently are "no treatments with proven efficacy for primary negative symptoms" (such as avolition). Together with schizophrenia's chronic nature, such facts added to the outlook of never getting well, might further implicate feelings of hopelessness and similar in patients as well as their friends and family.

In psychology and neuroscience, executive dysfunction, or executive function deficit, is a disruption to the efficacy of the executive functions, which is a group of cognitive processes that regulate, control, and manage other cognitive processes. Executive dysfunction can refer to both neurocognitive deficits and behavioural symptoms. It is implicated in numerous psychopathologies and mental disorders, as well as short-term and long-term changes in non-clinical executive control.

Executive dysfunction is not the same as dysexecutive syndrome, a term coined by Alan Baddeley to describe a common pattern of dysfunction in executive functions, such as deficiencies in planning, abstract thinking, flexibility and behavioural control. This group of symptoms, usually resulting from brain damage, tend to occur together. However, the existence of dysexecutive syndrome is controversial.

Apathy is a lack of feeling, emotion, interest, and concern. Apathy is a state of indifference, or the suppression of emotions such as concern, excitement, motivation, or passion. An apathetic individual has an absence of interest in or concern about emotional, social, spiritual, philosophical, or physical life and the world.

The apathetic may lack a sense of purpose, worth, or meaning in their life. An apathetic person may also exhibit insensibility or sluggishness. In positive psychology, apathy is described as a result of the individuals feeling they do not possess the level of skill required to confront a challenge (i.e. "flow"). It may also be a result of perceiving no challenge at all (e.g. the challenge is irrelevant to them, or conversely, they have learned helplessness). Apathy may be a sign of more specific mental problems such as schizophrenia or dementia. However, apathy is something that all people face in some capacity. It is a natural response to disappointment, dejection, and stress. As a response, apathy is a way to forget about these negative feelings. This type of common apathy is usually only felt in the short-term and when it becomes a long-term or even lifelong state is when deeper social and psychological issues are most likely present.

Apathy should be distinguished from reduced affect, which refers to reduced emotional expression but not necessarily reduced emotion.

Several drug therapies have been used on patients with KLS, but none of them have been subject to randomized controlled trials. A 2016 Cochrane Review concluded that "No evidence indicates that pharmacological treatment for Kleine-Levin syndrome is effective and safe".

In several cases, stimulants, including modafinil, have been reported to have a limited effect on patients, often alleviating sleepiness. They can cause behavioral problems, but they may pose fewer issues if used in older patients with mild symptoms. In some case reports, lithium has been reported to decrease the length of episodes and the severity of their symptoms and to increase the time between episodes. It has been reported to be effective in about 25 to 60 percent of cases. Its use carries the risk of side effects in the thyroid or kidneys. Anti-psychotics and benzodiazepines can help alleviate psychotic and anxiety related symptoms, respectively. Carbamazepine has been reported to be less effective than lithium but more effective than some drugs in its class. Electroconvulsive therapy is not effective and worsens symptoms.

KLS patients generally do not need to be admitted to hospitals. It is recommended that caregivers reassure them and encourage them to maintain sleep hygiene. It may also be necessary for patients to be prevented from putting themselves in dangerous situations, such as driving.

It was once assumed that anyone suffering from Korsakoff's syndrome would eventually need full-time care. This is still often the case, but rehabilitation can help regain some, albeit often limited, level of independence. Treatment involves the replacement or supplementation of thiamine by intravenous (IV) or intramuscular (IM) injection, together with proper nutrition and hydration. However, the amnesia and brain damage caused by the disease does not always respond to thiamine replacement therapy. In some cases, drug therapy is recommended. Treatment of the patient typically requires taking thiamine orally for 3 to 12 months, though only about 20 percent of cases are reversible. If treatment is successful, improvement will become apparent within two years, although recovery is slow and often incomplete.

As an immediate form of treatment, a pairing of IV or IM thiamine with a high concentration of B-complex vitamins can be administered three times daily for period of 2–3 days. In most cases, an effective response from patients will be observed. A dose of 1 gram of thiamine can also be administered to achieve a clinical response. In patients who are seriously malnourished, the sudden availability of glucose without proper bodily levels of thiamine to metabolize is thought to cause damage to cells. Thus, the administration of thiamine along with an intravenous form of glucose is often good practice.

Treatment for the memory aspect of Korsakoff's syndrome can also include domain-specific learning, which when used for rehabilitation is called the method of vanishing cues. Such treatments aim to use patients' intact memory processes as the basis for rehabilitation. Patients who used the method of vanishing cues in therapy were found to learn and retain information more easily.

People diagnosed with Korsakoff's are reported to have a normal life expectancy, presuming that they abstain from alcohol and follow a balanced diet. Empirical research has suggested that good health practices have beneficial effects in Korsakoff's syndrome.

Phineas Gage, who suffered a severe frontal lobe injury in 1848, has been called a case of dysexecutive syndrome. It should be noted however that Gage's psychological changes are overstated-, of the symptoms listed, the only ones Gage can be said to have exhibited are "anger and frustration", slight memory impairment, and "difficulty in planning".
