The causes of hallucinations often lie in different diseases
Hallucinations are called painful perception disorders, in the occurrence of which a person feels or sees phenomena that do not exist in reality.
If a person has a vision - the reasons for them should be sought in mental disorders, unlike illusion or a mirage, the altered psyche itself creates objects that are not in reality. There is an assumption that hallucinations from alcohol are characteristic only for those who suffer from mental disorders.
To the same category of people belong those who often abuse psychotropic drugs or use drugs. To some extent, this is really correct - people of this kind in real life belong to a group of high risk. But in general, one can not give a guarantee that healthy people are not exposed to the fact that they can develop hallucinations whose causes are obvious.
Experiments performed by
Scientists conducted experiments that yielded quite interesting results. Nineteen people, not burdened with any diseases, were participants in the experiment. Any person who took part in it for some time was alone in a room with special equipment.
It could not penetrate extraneous sounds or any images from the outside. Therefore, all recorded sensations were "created" by the human psyche, and could in no way be a reflection, even distorted, of a real event or circumstance.
Survey after the
experience After this, the scientists conducted a survey of volunteers about the sensations. Five people in the experience, reported that people "noticed" people. Six people reported that they "discovered" the movement of unfamiliar creatures. To the other six participants, "strange" sounds could not be explained, which could not be explained. A couple of people "watched" the presence of monsters in an empty room.
The first conclusion from the conducted experiments
As the organizers of the created experiment believe, a number of similar hallucinations can be explained by the fact that while the brain is used to receiving information regularly, it suddenly falls into the conditions of absolute absence of information data, and creates them himself.
The second conclusion from the conducted experiments
Also, psychiatrists are sure that people who participated in the experiment had auditory visions whose causes are not necessarily concentrated in a dark room. It is determined that prisoners who are in solitary confinement also often experience similar phenomena such as true hallucinations. Caught in the absence of any source of information, the brain has the ability to independently create different impressions.
Diseases that cause visibility
Tactile hallucinations often result from a pronounced state of affect, severe fright, certain chemicals.
Stress state
Stress, which is formed in the case of death of relatives, or in other tragic circumstances affects hallucinations - the symptoms of disorders can be very diverse. In any case, the reason that provoked their appearance should be very significant.
There are examples where functional hallucinations have been provoked by excessive infatuation, the impact of a strong sense of love. Suffice it in frequent cases, the manifestation of such a violation, as functional hallucinations, is due to severe trauma, or brain diseases.
Influence of trauma on occurrence of hallucinations
Visceral are formed in the presence of tumor-like formations, but can result from significant trauma.
Influence of stroke The specialists classify syphilis, temporal arteritis, aneurysm, olfactory meningioma, certain cardiovascular problems as a result of diseases causing hallucinations in stroke.
The factor of eye diseases
Special role in the development of this disease scientists are assigned to eye diseases. It is established that with glaucoma, cataract, and some other diseases, visual hallucinations appear.
Elderly age
In addition, hallucinations in the elderly appear with otosclerosis - these patients experience auditory disorders.
Difference between illusions and hallucinations
Individual people assume that illusions and hallucinations are the same false perceptions. But their difference is that false perception can be observed when there is no immediate object, whereas illusion becomes a distorted reflection of an existing event or phenomenon.
Hallucinations in healthy people
Healthy people see hallucinations much more often than one might imagine. For example, being in a long transition through the desert, tormented by exhausting thirst, it may seem that ahead appears a populated area, an oasis. In fact, similar objects are nothing more than a vision trickery.
But all the same, it should be noted that in a larger version of the case, people suffering from mental illness are hallucinated. In addition, in the overwhelming majority of cases, a person, regardless of his condition, is critical to illusions, assuming that there is in reality an object that is not quite correctly reflected, whereas when hallucinating, he is sure that an event or object exists in the real world.
Extracampal hallucinations can be observed on a par with visual impairment. True vision has a different character, and the patient is affected differently, regardless of the cause of the occurrence. For them, neutral coloration can be characteristic, or it can be completely without emotionality. Patients have a calm attitude toward them, at times even indifferent.
Exceptions to
But there are exceptions, when in the emotional plan of hallucination the causes are expressed quite clearly. Thus, a case is described from clinical practice, when a mother who lost her son did not leave the state of depression. In her hallucinations, she often saw the deceased, and these "meetings" gave her great joy.
