Qué Es La Depresión?

It is normal to feel sad from time to time like when you lose something or someone important and you feel really bad but eventually you recover and return to your normal life however, some people can not recover and remain in that state for a long time so have you wondered what depression is? Depression is a mental disorder in which the symptoms of sadness maintained for extended periods and in which the patient can not improve unaided As in other disorders the Symptoms vary depending on the individual plus, exist different degrees of depression for example the type of depression more Diagnosed is major depression, but there Also chronic depression, bipolar disorder, seasonal affective disorder among others each of these have small differences, but most share the following symptoms persistent sadness, loss interest in common activities guilt, irritability, indecisiveness, difficulty concentrating pain and suicidal thoughts, plus they are maintained for at least two weeks or more. The problem with Depression is that does not exist only one cause Because it result of various factors including genetic, biochemical psychological and environmental for example, a recent study showed that there is a gene responsible for serotonin transport which can have two sizes and since we have Two copies of each gene subjects with two small copies are more susceptible to get depressed than those with two Long copies for a long time Depression has been linked with deficiencies in the level of serotonin in the brain so today most patients are treated with drugs trying to balance the levels of this neurotransmitter however not all patients respond to such treatment so scientists now are using different techniques to balance brain function of patients with depression and other mental disorders. A technique that is having favorable results is called estimulacion cerebral profunda or Deep Brain Stimulation and is based on introducing electrodes in specific regions of the brain to increase or decrease brain activity in those regions as we have seen in previous videos all our capacities both sensory motor and cognitive are the result of the interaction of our neurons thorough Electrochemical impulses, so when a mental disorder occurs it is usually because a neuronal circuit is not working correctly for example in parkinson disease exists an over activation in the subthalamic nucleus causing the irrepressible tremor in patients so by using this technique doctors insert electrodes in that region to control by means of electric pulses the neurons that are generating the problem in the same way scientists form University of Toronto have located an specific area that is overactive when we are sad and they have used the Deep Brain Stimulation in patients with chronic depression non-responders to common treatment patients have reported that when thay turn the device on, begin to feel much better and eager to do things This same technique is being used to treat other mental diseases such as alzheimer disease anxiety and schizophrenia but in the near future could be used to treat any mental disorder or even to increase our cognitive abilities do you have have brain surgery to become more intelligent? leave it in the comments, suscribe and do not forget give thumb up!
