Learn, reason, deduce … all are functions of the left hemisphere. The intellectual brain is related to the verbal. Logical intelligence.

Neurology .- The left brain is associated with logic, reason and scientific thought of a person, where information processing to transform it into words becomes the specialty of this “logical hemisphere.” There are several left-brain functions, including control of mathematics, logic, speech, writing, numbering … Common sense rules in people with dominance of this hemisphere.
What is responsible for the left hemisphere of the human brain?

The left brain, by analysis and logic-is responsible for processing the information to transform it into words. His specialty is to produce and understand speech sounds.

This part of the brain is related to the verbal, there are two structures associated with the development of language ability:

Broca’s area. This area deals with the speech, its analysis and understanding of language.
Wernicke’s area. Another important area related to language and is connected to Broca’s area through a bundle of nerve fibers.

As early as 1878 John Hughlings Jackson, British neurologist described the left hemisphere as “the center of the faculty of speech.”

Functions of the left hemisphere

While the right hemisphere of the brain is related to non-verbal expression, is more emotional, sensitive, intuitive and coordinates the left side of the body, the left uses the analysis, mathematics, logic, reasoning, and controls the coordination of right side of the human body. The functions of the left hemisphere human brain based on control:

Spoken language (spoken language).
The written language.
Scientific thinking (scientific skills).
The reasoning (logical reasoning).
The ability to learn.
The deduction.
The numeracy.
The logic grammar.

One can say that the two hemispheres of the brain , the left is analytical and sequential ie the “brain drain” or “logical hemisphere.”
How are the people who use more than the left hemisphere?

In right-handed people the left hemisphere is dominant and they use more dialectic and common sense.

Use the logical process and tend to reason everything point by point.
Before making a decision or, predominantly people of this hemisphere are well informed about it. Sometimes fail to know what they want for reasons too.
They are intellectual people , analytical and very detailed.
Understand everything based on logical principles.

It is the logical hemisphere and understands that thinks in words and numbers. He is in charge of seeking an explanation.

When the origin of a physical problem has its starting point in a psychological aspect, then we speak of psychosomatic disorders.

In this blog we tell health details of a problem estimated to affect about 30% of patients who seek medical care.

Have physical symptoms and not knowing where they come from. Try everything to solve these problems but nothing that can not be solved.

In many cases, when a patient has physical problems, often have a psychological origin and we are talking about a psychosomatic disorder.

Schizophrenia is a mental illness rather unknown and mysterious, and yet not quite know where. To learn more about her health in this blog have asked us why there is schizophrenia, a severe mental illness that affects 1% of the population.

The exact causes of schizophrenia are unknown, although most experts point to a “limited supply” is responsible. In this sense, the idea is that each person has a number of more or less noticeable handicaps for the development of life, and indeed, in certain situations, not all react the same (whether biological or mental level).

The results of a study published in the journal Neurology suggests that the declaration of brain death occurs under certain complex circumstances, and is usually performed on patients who are hemodynamically unstable, requiring vasopressors and vasopressin.

In many cases, the apnea test can be completed successfully. In those who could not successfully carry out other tests are required to confirm brain death.

To determine this result performed a detailed review of 228 patients who were declared brain dead at the Mayo Clinic between 1996 and 2007.

Most of these cases were the result of a traumatic brain injury (32%) or intracerebral hematoma, or aneurysmal subarachnoid hemorrhage (39%).

Brain death was declared within 24 hours after admission in 69 patients (30%), 1 to 2 days after admission in 47 patients (21%), between day 2 and 3 in 26 patients (11 %), and after three days in 86 patients (38%).

The proof of apnea can not be done in 16 patients because haemodynamic instability or poor oxygenation at baseline.

Traumatic brain injury in patients with multiple trauma were more significant for patients who could not perform, or in which they had to stop, the apnea test than those who could complete the test.

The way in which some patients experience delirium, a confusional state, predicted mortality, according to a study by the Institute for Aging Research of Hebrew Senior Life.

Patients with severe hypoactive delirium, characterized by a slowdown or lack of movement and apathy, are the worst survival rates for the next six months, regardless of illness suffered.

People with slightly hypoactive delirium are more likely to die than other patients with milder symptoms.

The study, published in the journal Psichosomatics, is the first to correlate the subtypes of delirium caracteríticas or the severity of the disease.

The four sub-types of delirium are normal hypoactive, hyperactive, and mixed types combining trade items hiccups and hyperactive.

By using two standard screening tools, the researchers examined whether the classic psychomotor subtypes of delirium are reflected in the severity of delirium. In addition, it examined whether the subtypes were able to predict mortality.
