Celiac disease and schizophrenia

Signed a study by researchers at the Johns Hopkins University (United States) and the Psychiatric Hospital in Aarhus (Denmark), concludes that schizophrenia may be related to allergy to gluten. According to published in the British Medical Journal ", the history of celiac disease is a risk factor for schizophrenia.

Therefore, in addition to recommending a gluten-free diet for celiac patients, commented that a clinical trial has found that eliminating grains from the diet also relieves symptoms of schizophrenia. The new study examined nearly 8,000 patients with schizophrenia in Denmark.

Institutionalization syndrome

In 70 years, a psychologist at Stanford University David Rosenhan demonstrated in an experiment that once someone is catalogued for mentally ill, will cost rid of the label, do what you do.

Mandó eight people ropes to a psychiatric hospital, where he told that suffered hallucinations and heard voices.
After being admitted, all of them behaved with complete normality, in vain: being diagnosed with schizophrenia.
Only noticed the real sham patients, they said: "you are not crazy, you've come here to investigate."

The enigma of twins

The behavior of the four Genain twin sisters, born in the U.S. in 1930, drew the attention of psychiatrists at the time.
As a child, Hester broke light bulbs and was booted ios buttons; Nora gems during meals and put on their knees and elbows to bleed, with 22 years, Iris stopped working because he felt "trapped"; Myra was better, but are easily frightened and reassure her hard work.

The four were diagnosed with schizophrenia, which seemed to prove the importance of genetic factors, since the probability that the disorder affects four people chosen at random is 1 in 100 million.

Moreover, the degree of gravity was different in each one, which indicated the presence of other factors, but what?

The psychologist David Ro-senthal explained the differences in degree from family relationships, as Myra, the less sick, was the favorite of the mother, and Hester, the most serious, since girl was labeled as "bad".

For his part, the neuropsychologist Alian F. Mirsky discovered that the twins through tomography most affected also showed more abnormalities in their brain activity and that their frontal lobes, which act as a focal point for information, were weaker and less energy consuming than those of their sisters.

According Mirsky, Genain suffered varying degrees of injuries due to the order of their birth. Nora could suffer trauma as the first to pass through the uterus and Hester, most recently, by lack of oxygen.

The brain scanner in a recent case of twins, Elmore, proved that the ventricles of Steven, schizophrenic, had thicker tissue and neuro-nal thinner than the mentally healthy David.

Symptoms of a psychotic

The sense of Political decoy brings us closer to the field of psychosis, a type of mental disorders in Spain that affect 440,000 people, according to the Congress for Psychotherapy of Schizophrenia and other psychoses, 2006.

To focus the issue, should be distinguished from psychotic disorders of the neurotic; those-such as depression-affecting the mood, but do not "lose your head", while the psychosis is characterized by the loss of a sense of reality and the vision of the world that shares the generality of humans.

Woody Allen said that "a psychotic is someone who thinks that two two are five, a neurotic knows that there are four but does not like." According to the psychiatrist Thomas Szasz, there is another difference: "in psychiatry is a person qualifies for neurotic if you suffer for their problems, and if you suffer from psychotic to others."

The most common symptoms of psychosis are in the form of cognitive disorders, perceptive, emotional and behavioural. The first-the cognitive-affecting intelligence, reason and understanding and make, for example, ideas of who suffers from becoming strangers to each other.

It also alters the thread of thought: no one understands the relationship they have with some other ideas except the affected. His speech becomes confused, his thoughts seem to accelerate or slow down and has difficulty concentrating, follow the thread of the conversation or remembering recent events.

Sometimes cree suffers from delusions and unusual things, for example, by the way that cars parked next to his house, thinks that the police are monitoring him and any reasoning or evidence against achieved disappointments.

Quantum Immortality and Suicide in Parallel World

This imaginary experiment of the quantum mechanics was developed by Max Tegmark, in 1997, in which seek to be distinguished between the Interpretation of Copenhagen and the Interpretation of Multiple Worlds, using a variance of the experiment of the Winch of Schrödinger. The variance that insert this experiment is the one of taking the point of view of the winch, inserting us inside the box.
The experiment is the following one:


A physique sits down in front of a you arm that point to your head. The weapon has a device that will work it, depending on the disintegrator of a radioactive atom. Every time that crowd together the trigger, the disintegrator, or not, of the particle it determines if the weapon is shot. According to the Interpretation of Copenhagen, the weapon will be shot possibly, there being 50% of possibilities that you make it, and that the physique dies. But, according to the Interpretation of Multiple Worlds, for each triggered, the Universe is divided in two; the physique will only die in 50% of the parallel worlds in those that the weapon is shot. In the other 50% of the worlds, the physique won't die. No matter how much you repeat the experiment, the weapon you won't be shot. What take to the idea of a Quantum Immortality.


A curiosity is that, the esquizofrénica daughter of Hugh Everett III, the designer of the Theory of Multiple Worlds, committed suicide leaving a note, in which were justified saying that you would go to a parallel Universe to be with your father that had already died behind fourteen years.

Schizophrenia

The psychoses esquizofrénicas are the mental most serious and frequent illnesses, since more than half of the chronic confined sick persons they suffer them. They can be defined as the group of psychic dysfunctions in those that the oncoherencia ideoverbal, the ambivalence, prevails the autism, the delirious ideas, the hallucinations and affective deep disturbances, as absence and strangeness of the feelings. This conunto of dysfunctions spreads to evolve toward a dissociation and segregation of the legal capacity.

The fundamental features of the symptoms esquizofrénicos are the following ones: excision of the legal capacity (I overturn fundamental, consistent in a rupture of the harmony of the me and of the psychic normal mechanisms); absurdidas, strangeness and psychological incomprensibilidad of the sick person's (your mind is governed by the new and unknown laws) vivencias; incongruity of the behavior; strangeness of itself, autism and rupture of the contact with the relaidad; catastrophic (with the one that the sick person foresees the destruction of your legal capacity) vivencia.

These illnesses can cause gradually, by means of a long and insidious process, or in an acute and sharp (call emerges) way. Your lawsuits, very diverse, are very debated in the different schools psiquátricas. Diverse factors can exist: genetic, biotipológicos, psicotípicos of predisposition, neurobiologic (energy dysfunctions and dismetabólicos, endocrine dysfunctions) and finally psychosocial (among those that have special importance the biographical events of the childhood, the socio-cultural mean and the relationships interfamiliares). In general, two theories etiopatogénicas prevail: the organicista (for which the schizophrenias are linked illnesses of somatic origin to a consitución and transferable for inheritance) and the psicogenética (for which the esquizpfrenias is reacciónm modes from certain types of legal capacity to specific conflicts). In fact, according to the theory psicogenética, the schizophrenias would be the final result of the uptake in anomalous ways of reaction originated in very early ages before conflicts that cannot remember. New conflicts unchain these latent reaction modes.

They exist, diverse types of psychosis esquizofrénica. The clinical most frequent and typical form is the paranoid schizophrenia that are characterized by the appearance of delirious primary ideas. Delirious secondary ideas and alucinaicones are also added; these three symptoms constitute the core of this schizophrenia. The beginning can be gradual or sharp. Frequently, the delirious ideas of persecution and of poisoning they go accompanied by auditory, visual, smell hallucinations, etc., that they confirm to the sick person in your delirious ideas. He/she usually appears in plenum adultes and even in advance ages.

The other forms clinicians differ for your evolutionary potential. You are two forms that have a very important, more included potential evilutivo that that in the typical or paranoid way, and that they constitute the serious schizophrenias.

In the first place, the schizophrenia hebefrénica are, of insidious and progressive beginning, mainly in the adolescents (school difficulties, you shrink of the performance, hypochondriac crisis and sensation of fatigue). During the beginnings it can seem a neurosis, but after some months or one year the sick person lives as dreaming and you pass to the fundamental symptoms of the illness: progressive apathy with indeferencia regarding everything, infantile behavior and massive and quick trend toward a state serious demencial.

The second serious schizophrenia is the catatonic one. In this illness the psychomotor symptoms prevail, together with a great negativism (I lock of the voluntary activity, being only conserved the self-operating activity). Of all the esquizofrénicos it is the catatonic one the one that give a more intense sensation of insulation of the reality and of rupture with the normal forms of relationship. The psychomotor syndrome can enter two forms: the hipocinética (in the one that the reduction in value of the movement, the forfeiture of all initiative, prevails until the grade of conserving the postures imposed hours and even days, and the mutismo) and the hipercinética, be local or general (in the one that episodes of semiautomatic intense agitation appear, without the sick person of a reduced space that you/they lose temper with periods of immobility being exitted). In general the sick person, although non lomparezca, is pending of your acts. The evolution toward the dementia is carried out in 3 or 4 years.
