This state of the human psyche is characterized by an acute onset and variable symptoms - symptoms of different types of known mental states of varying intensity replace each other quite quickly, preventing diagnosis of any of them. Such polymorphism forced this psychosis to be singled out as a separate nosological unit. Polymorphic psychotic disorder develops as an acute psychosis in people who have not previously come to the attention of psychiatrists. It is impossible not to notice it, the abnormal behavior of the patient is striking to everyone - the mechanism of perception, associative thinking is disrupted, emotional instability is evident.
With a preliminary diagnosis of "Acute polymorphic psychotic disorder" most patients are hospitalized in a psychiatric hospital for the first time. The term "psychotic" itself indicates that a person has a severe mental disorder that makes it impossible to perform his professional duties and ensure personal life and causes the need to see a doctor and get treatment. In addition to the acute onset and severe course, this mental pathology is characterized by short duration and complete recovery.
Causes of polymorphic psychotic disorder
French psychiatrists called such states delirious outbursts, Japanese – atypical psychoses, Soviet ones attributed them to some types of reactive psychoses, since it had long been noted that such a state arises as a reaction to a recent acute psychotraumatic situation that occurred no more than two weeks before the manifestation of acute psychosis. Long-term sluggish stress, a prolonged struggle with problems on the everyday front do not cause acute psychotic reactions.
Risk factors for the development of this rather severe mental disorder may be associated with the unexpected loss of a loved one, their death or a break in relations with them, with financial collapse, with a recent episode of violence, other significant losses for this individual, material and spiritual. Psychotraumatic factors can be triggers that contribute to the implementation of individual personality traits formed under the influence of the genotype or pathological intra-family relationships in early childhood. Often the causes of transient acute polymorphic mental disorder remain unknown.
At present, there is insufficient clarity in understanding the pathogenesis of even the main mental illnesses, much less polymorphic disorders. There are many hypotheses attempting to explain the mechanisms and conditions of the formation of acute psychoses. The most modern ones associate the pathogenesis of their development with a violation of the exchange of the main neurotransmitters of the nervous system (serotonin, dopamine, norepinephrine), which transmit nerve impulses in various instances of the cerebral cortex.
World medical statistics estimate the share of acute polymorphic psychotic disorders at 4% of all cases of psychosis of non-organic origin (including affective). Female patients with such a final diagnosis are found approximately four times more often than male patients. The age of most patients is between 30 and 50 years. As already mentioned, acute polymorphic psychotic disorder is diagnosed most often during primary hospitalization, however, such a diagnosis is not always confirmed. If remission does not occur within three months, it is reviewed without fail.
Symptoms of polymorphic psychotic disorder
The first signs are noted by others as a noticeable and significant disruption of normal behavior. Symptoms increase very quickly, literally every day behavioral anomalies become more pronounced: unstable mood - changing very quickly, sometimes several times during the day, the patient's speech becomes meaningless, intermittent multifaceted delirium appears, different types of hallucinations - the patient feels touches and smells, hears sounds and voices. The productive symptoms of the disorder are polymorphic and simultaneously resemble schizoaffective or delusional disorder, paranoid psychosis, manic and depressive episodes, schizophrenia, but in general do not meet their symptomatic criteria.
The patient does not show any pronounced temporal and spatial disorientation, self-identification is practically preserved. The patient is often confused, his concentration decreases, other symptoms of partially clouded consciousness appear, however, not as severe as in organic diseases of the brain, the symptoms do not indicate them. Also, psychosis cannot be directly associated with the use of psychoactive substances, it is not caused by intoxication or withdrawal syndrome.
The types of polymorphic psychotic disorder identified in the latest classifier of diseases (ICD-10) are mainly differentiated by the presence or absence of schizophrenic manifestations, since this group of mental disorders is very heterogeneous in structure and it is not possible to combine them by any other characteristic.
The following types are distinguished:
- acute polymorphic psychotic disorder without symptoms of schizophrenia - the symptoms correspond to those described above, the types of delusions and hallucinations do not correspond to schizophrenic ones, violent manifestations of enthusiasm, reaching ecstasy, are replaced by depression and apathy, polymorphism and emotional instability are manifested very expressively (when the symptoms are stable and long-term, they should be interpreted as a manifestation of acute delusional disorder or cycloid psychosis);
- acute polymorphic psychotic disorder with symptoms of schizophrenia - along with the symptoms described above, there are signs of schizophrenic-type delusions - oppression, influence (for example, force fields), exaltation, or the presence of a serious illness, the forms of delusions are constantly changing; auditory hallucinations - the patient hears voices ordering him to do something, reproaching him, threatening, condemning, paralogical reasoning, symbolism and discontinuity of thinking are noticeable, pseudo-hallucinations and a symptom of openness of thoughts are possible; in the emotional sphere, anxiety and fear prevail, but emotional-volitional negative pathologies are absent, agitation is expressed by irritability, motor activity (when the symptoms are stable and long-term, they should be interpreted as a manifestation of acute delusional disorder or cycloid psychosis, but already with symptoms of schizophrenia);
- acute schizophrenia-like psychotic disorder - against the background of all the same manifestations, productive symptoms of schizophrenia predominate; if they do not go away within a month, the diagnosis is changed to schizophrenia;
- Other types of transient disorders are much less common, are characterized by some specific psychiatric symptoms and belong mainly to the delusional and paranoid types.
Acute polymorphic psychotic disorder is always treatable, and the symptoms are quickly relieved with medication. Rapid development, a fairly severe course, and short duration (sometimes regression occurs after a few days) are also signs that the patient has polymorphic personality disorder, and not a manifestation of another more serious progressive mental illness.
Complications and consequences
The greatest danger of such a condition is that it may be a manifestation of a mental illness, in particular schizophrenia, such a development of events is indicated by the stability of symptoms and their presence for more than three months. The earlier the treatment of such a disease is started, the more favorable its prognosis will be.
Acute polymorphic psychotic disorder is completely curable, passes without complications, consequences and is considered a single episode. But during the acute state, the patient is socially maladapted, can be dangerous to himself and others, requires protection and care.
Diagnostics of polymorphic psychotic disorder
The doctor makes a preliminary diagnosis after listening to the patient's complaints or those of his relatives, based on the description of the symptoms, the rate of development of psychosis (the time interval from the appearance of the first symptoms to the development of the full picture should not exceed two weeks). A report of a traumatic event that occurred in the recent past (up to two weeks) has diagnostic value.
Using special methods, an experimental psychological examination is carried out to identify disturbances in higher nervous activity processes.
General diagnostic tests that provide an idea of the patient's condition - blood and urine tests, biochemical blood composition may be normal, deviations from the norm rather indicate the presence of concomitant diseases. A consultation with a therapist, neurologist and other specialists may be prescribed.
Instrumental diagnostics usually do not show significant deviations from the norm and are prescribed for differentiation in order to exclude diseases with similar clinical course.
Tomography, computer or magnetic resonance, allows to exclude current organic pathologies, electroencephalography is prescribed for seizures, echoencephalography - for the presence of clouded consciousness, electrocardiography is performed to monitor the body's response to drug treatment.
Differential diagnosis
Differential diagnostics are carried out with psychoses of organic origin, schizoaffective disorder and manifestation of schizophrenia, delirious states due to poisoning syndrome or withdrawal of psychoactive substances.
The main diagnostic marker is the duration of the period of presence of clinical symptoms. If pathological symptoms were observed for no more than one month and ended in recovery, the diagnosis of polymorphic psychotic disorder is fully confirmed. If clinical symptoms are present in the period from one to three months, the diagnosis is already considered doubtful, however, it can still be confirmed. A longer course of the disease requires a revision of the diagnosis.

Treatment of polymorphic psychotic disorder
Acute polymorphic psychotic disorder has a short-term but severe course. After examination and diagnosis, the patient may be left at home if the symptoms of the disorder are not threatening and relatives can provide the patient with proper care, timely medication and support to monitor treatment.
In most cases, patients are hospitalized in a psychiatric hospital. The criteria for hospitalization for polymorphic disorder, which are voluntary, include antisocial behavior of the patient, the manifestations of which cannot be relieved by outpatient treatment. The second option of voluntary hospitalization is carried out when there is a need for constant observation to submit materials for consideration by expert commissions to determine the patient's ability to work.
In the presence of psychopathological actions of the patient, posing a danger to others or to himself, he is forcibly placed in a psychiatric hospital. Also, if it is necessary to provide constant psychiatric medical care in order to prevent the deterioration of the symptoms of the disorder, the patient is hospitalized without his consent. If the patient is in a helpless state, and there is no one to provide proper care, the patient's consent to hospitalization is not required.
In cases where a patient has already committed an illegal act, he may be placed in a psychiatric hospital by court order.
A standard treatment protocol is used to relieve symptoms of acute polymorphic psychotic disorder. The main drugs used to eliminate productive manifestations of psychosis are neuroleptics. Currently, the drugs of choice are atypical neuroleptics, which have a more favorable safety profile than typical ones. Their effectiveness is approximately equal, so the choice of drug is based on the best patient tolerance (allergic reactions, concomitant diseases, possible resistance). The choice of drug is also influenced by the structure of the most pronounced syndrome, the presence of pathological prerequisites (hereditary predisposition, stress, somatoneurological diseases).
Acute psychosis with primary productive schizophrenia-like symptoms can be relieved with Amisulpride. A new-generation atypical neuroleptic has the ability to exert antipsychotic effects - reduces the severity of delirium and hallucinations, as well as depression and inhibition. It has a sedative effect. Side effects are noted mainly with high-dose long-term use. Epileptic seizures, sleep disorders, sexual disorders, weight gain and other side effects may develop. Potentiates the effect of drugs that depress the central nervous system. Incompatible with alcohol and levodopa.
Risperidone is used to relieve productive symptoms (delusions, hallucinations) of various structures. The agonist of serotonin and dopamine receptors reduces irritability, causes inhibition of abnormal motor activity. Contraindicated in patients with epilepsy and Parkinson's disease. This drug causes extrapyramidal disorders more often than other representatives of this group. Negative symptoms of schizophrenia may also occur as side effects. Hyperprolactinemia is often observed, so the drug, like the previous one, is contraindicated in breast cancer.
In cases of predominant psychomotor agitation, a typical neuroleptic, Aminazin, may be prescribed. It has a diverse and complex dose-dependent effect on the functioning of the central and peripheral nervous system. Increasing the dose causes an increase in sedation, the patient's body muscles relax and motor activity decreases - the patient's condition approaches the normal physiological state of sleep, which differs from narcotic sleep in that it is devoid of the side effects of anesthesia - stupor, and is characterized by ease of awakening. Therefore, this drug is the drug of choice for stopping states of motor and speech agitation, anger, rage, unmotivated aggression in combination with hallucinations and delirium, especially at the stage of first aid.
All antipsychotics have a direct effect on the occurrence and conduction of nerve impulses that transmit excitation in different parts of both the central and autonomic nervous systems. Under their influence, metabolic processes in the brain tissues slow down, especially in the neurons of its cortex. Therefore, the neuroplegic effects of the drug are associated with cortical types of activity. Medicines of this group suppress almost all types of psychomotor agitation, relieve hallucinatory and delusional symptoms, but are not sleeping pills. A patient under the influence of a drug of this group is able to adequately respond and answer questions.
They can be used both independently and in combination with anxiolytics and other psychotropic drugs. Absolute contraindications to the use of antipsychotics are severe systemic pathologies of the brain and spinal cord, dysfunction of the liver and kidneys, hematopoietic organs, myxedema, a tendency to thromboembolism, decompensated heart disease.
It is used to treat patients of any age, dosed individually, according to age norms and severity of the condition. Oral administration is possible, as well as parenteral (usually in a hospital).
After using neuroleptics, especially in injection form, a drop in blood pressure is possible, so the patient is advised to lie down for several hours and take a vertical position without sudden movements. In addition, other side effects are possible - allergy, dyspepsia, neuroleptic syndrome.
Antipsychotic therapy is carried out according to general principles. Oral administration of one drug is preferred for a minimum duration of ten days to two weeks. The achieved treatment effect is then assessed. The condition may already be relieved, however, if there is resistance to treatment, two atypical antipsychotics are prescribed simultaneously. Drugs with different chemical structures are selected.
After ten days, if there is no effect, treatment with more powerful typical antipsychotics is started. No more than two drugs of this group are prescribed in parallel, and even two drugs of the same chemical structure.
Corrective treatment is recommended to begin only after the development of side effects. For example, when extrapyramidal disorders manifest - tremors in the limbs, numbness, dyskinesia, Cyclodol (trihexyphenidyl) is prescribed. The drug has a powerful central and peripheral anticholinergic effect, eliminates movement disorders, hypersalivation (until dry mouth appears), hyperhidrosis. As a result of taking Cyclodol, the pulse quickens, intraocular pressure increases, delirium and hallucinations may return.
The treatment regimen may include drugs to eliminate concomitant mental pathology:
- normothymic agents (finlepsin, lamotrigine) – to stabilize biorhythms, normalize the emotional background, and at the same time stop epileptic seizures (a side effect of antipsychotics);
- anxiolytics (phenazepam, diazepam) – to relieve symptoms of anxiety and fear;
- antidepressants - preference is given to selective serotonin reuptake inhibitors (fluoxetine, sertraline); if they are ineffective, tricyclic antidepressants (amitriptyline) may be prescribed.
The treatment regimen is supplemented with medications that have a beneficial effect on brain function - nootropics and B vitamins are prescribed, as well as for the liver (hepatoprotectors).
After the symptoms of the acute condition have been relieved, the patient is prescribed a course of psychotherapeutic treatment. The patient may be admitted to a day hospital.
Neuroleptic therapy is continued after discharge, gradually reducing their dose or replacing them with prolonged-release drugs. Treatment can only be stopped with the doctor's permission.
Prevention
Preliminary prevention of acute polymorphic psychotic disorder is not carried out, since it is impossible to predict. However, recommendations regarding a healthy lifestyle, good nutrition, feasible physical activity, and a positive way of thinking are relevant in this case as well. They are the key to increasing stress resistance.
Relapse prevention can be achieved through autogenic training, yoga, and psychotherapeutic groups. Homeopathic treatment and herbal medicine will also help to avoid the development of repeated acute psychosis.
Forecast
Polymorphic psychotic disorder, both with and without schizophrenia symptoms, is treatable to full recovery. This statement concerns the final diagnosis. If such a medical conclusion was preliminary, then the prognosis depends on the disease that manifested itself under the guise of this psychosis.
