Lability is a concept used to refer to mobility. The scope can slightly change the semantic characteristics, denoting both the number of nerve impulses transmitted per unit time by the cell, and the speed of starting and stopping mental processes.

Lability characterizes the rate of flow (from the occurrence of the reaction to inhibition) of elementary processes, and is measured by the highest pulse reproduction frequency without changes in the work of the tissue and the recovery time of functions. This indicator is not considered constant because it can vary from external factors (heat, time of day, forceful effects), chemical effects (produced by the body or consumed) and emotional states, therefore it is possible to observe only the dynamics and predisposition of the organism, the prevailing level. It is the change in the lability indices that is key in the diagnosis of various diseases and norms.

What is lability

In scientific application, lability is used synonymously for mobility (normal), instability (in case of pathology) and variability (as characteristics of the state and process dynamics). To understand the breadth of use of this term, we can consider examples of the fact that there is a lability of mood of body temperature, psyche and physiology, and accordingly applies to all processes that have in their performance speed, consistency, rhythm, amplitude and other dynamic characteristics.

The flow of any body processes is regulated by the nervous system, therefore, even speaking of indicators of pulse lability or mood, we still speak about the degree of lability of the nervous system (central or vegetative, depending on the localization of instability). The vegetative nervous system regulates the internal organs and systems, respectively, the general condition of the body depends on its work, ability to maintain rhythm and stability of processes.

Vegetative lability brings disturbances in the heart (manifestations find themselves in the form of arrhythmias, problems with pressure and as vegetative-vascular dystonia), glands work (problems with sweating or the development of substances necessary for high-quality functioning of the body can begin). Many seemingly psychological problems or those related to the central nervous system are actually solved at the level of vegetative lability reduction, which ensures productive sleep and assimilation of beneficial trace elements. At the same time, it is worth remembering that signaling the level of stress or a critical emotional situation is not primarily the central, but the vegetative system, increasing its lability. Mechanisms that activate the work of all organ systems to overcome severe or extreme situations involve the body's internal reserves, causing the heart to speed up the rhythm, the lungs absorb more air, iron to remove excess adrenaline with sweat, and only then the central nervous system responses are activated.

The lability of the nervous system or mental lability is characterized by a pathological state of mood disorder, expressed in its differences and inconstancy. The condition may be the norm for adolescence, but be counted among the range of pathological conditions for adults and requires medical assistance, as well as the work of a psychologist, even without prescribing drugs.

Lability in psychology

Psychic lability, considered in psychology, implies its mobility, and in some cases, instability, while science itself studies only this aspect of lability, without going into physiology. In most sources, mental lability is considered as a negative quality that requires correction, but it does not give due to the fact that it is the main adaptive mechanism of the psyche. It was the speed of reaction and switching between quickly and often unexpectedly alternating events of external life that helped humanity to survive. The opposite is the rigidity of the psyche, when for a long time a person remains constant, and any changes knock him out of the normal state. Any of these characteristics in its extreme manifestation is negative, and with moderate indicators gives its advantages.

Problems with lability, when a person comes to a psychologist, are associated with a frequent change of mood, while all the spectra are lived not superficially, but really deeply (that is, if it became sad before thinking about opening veins, and if you are having fun, then you want to dance on workplace and give candy to passersby - and all this within one hour). It is difficulties in coping with their emotions and misunderstanding how this can be corrected brings many and not only mental suffering, but the following changes in health, because the vegetative system, being subject to emotional states also increases its level of lability.

Such phenomena can be justified by the type of organization of the nervous system, so in people with a choleric type of temperament, the speed of reactions is already determined by nature, and, accordingly, the increased lability to a pathological state is more likely. Also provoke mood swings can frequent neurosis, psychotrauma obtained at an early age, being in traumatic situations at the moment. But we should not exclude the physiological causes that affect the psychological state of a person: brain tumors, TBI, vascular diseases.

Correction of such unpleasant conditions begins with the diagnosis and exclusion of physiological causes, then, if necessary, correction with mood stabilizing drugs (antidepressants and tranquilizers) is possible, accompanied by a course of psychotherapy. With severe may be relevant treatment in the hospital, with the easiest, you can cope by visiting a psychologist, without departing from the usual life.

Lability in physiology

In physiology, lability is considered as a property of the tissue, characterizing its change upon prolonged excitation. Reactions to prolonged arousal can be expressed in three types of response: the response to each pulse, the transformation of the original rhythm into a rarer one (for example, the response to every third pulse) or the termination of the response. For each cell of the body, this rhythm is different, and it may differ from the rhythm of the organ consisting of these cells, as well as from the rhythm of the entire organ system. The faster the tissue reacts to irritation, the higher its lability is considered, but at the same time there are few indicators of this time only, it is necessary to take into account the time required for recovery. So, the reaction can be quite fast, but due to the long recovery time, the overall lability will be quite low.

The lability increases or decreases depending on the needs of the organism (the variant of the norm is considered, without diseases), so it can increase from the metabolic rate, which causes all systems to accelerate the rhythm of work. An increase in lability has been observed, that when the body is in a working active state, i.e. the lability of your tissues is much higher if you run, than if you read lying, and the indicators remain in an elevated value for some time after the cessation of vigorous activity. Such reactions are associated with the assimilation of rhythm that meets current environmental conditions and activity needs.

The adjustment of physiological lability can also be addressed in case of violations of the psychological spectrum, since many states have as their root cause not physiological disorders or emotional experiences, but physiological disorders. For example, physiological effects can remove problems with sleep, which will automatically increase the level of attention and reduce irritability, the treatment of which without physiological parameters would be ineffective.

Intellectual lability

Intellectual lability is one of the components of the lability of the nervous system and is responsible for the processes of switching between the processes of activation and inhibition. In life, it looks like a fairly high level of mental development and the ability to logically analyze incoming information. Since a critically huge amount of information blocks requiring perception comes in every second, it becomes necessary to sort them out into significant and non-significant as quickly as possible (at the subconscious automatic level).

The presence of a large knowledge base in memory becomes irrelevant and indicates not intelligence, but erudition, the ability to switch between different sources of information, between different information in meaning, and also in the shortest time to move to the next solution (even if the opposite ) tasks. With this switching speed, the main thing is to retain the ability to highlight the most important thing for the task at the given time. It is this process of intellectual work that ensures high intellectual lability.

Previously, they did not know about such a property, then they said, but rarely, but now, when the pace of life is accelerating, the amount of information consumed is growing at such a rate that a person who lived two hundred years ago would need a month to realize that we process within an hour , it becomes the determining factor of success. This gives the ability to respond adequately and as efficiently as possible in changing conditions, facilitates instant analysis of many factors, which allows minimizing the possibility of error.

In addition, the rapid switching between different topics and perspectives gives a non-standard thinking, new ways to solve old problems, there is a rapid assimilation of knowledge and skills, and this happens at a deeper level. For example, historical data on the same event, drawn from different sources (there is no longer possible without using the capabilities of the modern world) gives a more objective and large-scale understanding than quoting the textbook author’s point of view. The ability to learn quickly due to the fact that there is no need to tune in to the receipt of material - a ten-minute reading of an article in a minibus, accompanied by listening to new music or writing a diploma with breaks to watch the training videos becomes a familiar way of functioning, providing new opportunities.

Emotional lability

The mood lability, which is the main reflection of emotional lability, is the variability of the attitudes pole, often without any obvious reasons. The nervous system is responsible for our emotional state, and when it is weakened, it becomes supersensitive, which explains the instantaneous and strong reaction even to minor stimuli. Coloring can be any - both happiness and depression, aggressive affects and apathetic sadness arise with equal ease.

Symptoms may include spontaneity of actions, impulsivity, lack of self-control and the ability to predict the consequences of their own actions. The occurrence of affective outbreaks and uncontrolled states for minor or absent reasons caused emotional instability to be included in the lists of psychiatric deviations requiring stabilization under medical supervision. It may also be not a separate disease, but a symptom of more dangerous and complex (severe tumors, problems with pressure, hidden consequences of craniocerebral injuries, etc.). It is difficult to diagnose in childhood, because it is little studied and is often confused with hyperactivity and attention deficit syndrome, therefore a team of psychiatrist, psychologist and neuropathologist is needed for diagnosis.

Emotional instability manifests itself in restlessness, lack of patience and a keen response to criticism or obstacles, difficulties in establishing logical chains, as well as mood swings. These differences are different from manic-depressive disorder and are characterized by a rapid change of states with the same deep experience of the emotional spectrum.

Contributes to this development of the emotional sphere of any overload of the nervous system: emotional stress, psychotrauma or their actualization, hyper-or hypovo-taking from the society, hormonal changes (adolescent and menopausal age, pregnancy). Of the physiological causes: somatic diseases, vitamin deficiencies (especially group B, necessary for the maintenance of the NS), as well as severe physical conditions.

If emotional lability is made as a diagnosis, then the psychiatrist should deal with its adjustment, if the condition is not so deplorable, then a course of prevention and self-regulation by a psychologist is prescribed. In any case, it is not worthwhile to treat scornfully such manifestations, explaining it to be a bad one.
