In geology, an exogenous phenomenon is one that develops on the surface of the planet, and not inside.
The adjective exogenous refers to that whose origin is external ( exterior ). The term is usually used in the field of biology and in the field of geology , for example.
At the biological level, the organ, agent, substance, effect or stimulus that arises outside the organism is classified as exogenous. A health disorder, in this framework, can have exogenous or endogenous causes.
The environmental factors that affect a developing fetus, to cite one case, are exogenous. If the mother, at work , inhales toxic substances found in the air, her baby may suffer various problems. These problems have an exogenous origin.
An exogenous infection , on the other hand, occurs when the agent reaches the host from an external source. This happens with sexually transmitted diseases. In endogenous infections , the agent is already colonizing the host and the infectious process is triggered by a modification of the agent-host relationship.
exogenous depression
For psychology , exogenous depression is that which arises from external events : losing a job, suffering the death of a family member, etc. Endogenous depression , on the other hand, breaks into the brain without an external factor, motivated by physiological alterations or genetic causes.
Although depression can arise from different causes, the symptoms of both types are quite similar in most cases. This is one of the first obstacles when diagnosing it and, therefore, indicating appropriate treatment . However, some of the more specific symptoms can help psychologists determine their origin even if the patient has not evidenced it.
Exogenous depression is caused by external factors.
The pessimism
One of them is pessimism regarding the future . Why is this symptom not as common in endogenous depression as in exogenous depression? Because in the first type, the person can suffer from the disease from a very early age and become "accustomed" to the ups and downs that it entails, while in the second it is common for them to experience great disappointment due to an event that surprises them and leads them. to lose hope in general.
This pessimism also tends to overshadow the positive things taking place in your life. Another of the most common symptoms is irritability , which is usually accompanied by anxiety . If we think that an external factor changes the patient's life for the worse and without prior warning, it is understandable that he becomes distrustful, that he feels that bad luck is chasing him and that he gets angry at anything that does not go as expected, thinking that misfortune It's just around the corner.
As a logical consequence of these alterations in personality, there is a loss of interest in the things and people around the individual, even in their favorite activities . The mere possibility of another negative milestone breaking into his life leads him to withdraw into himself to protect himself.
Sleep disturbance is another symptom of exogenous depression. This can be seen at both extremes: sleeping too much or having great difficulty falling asleep. It is also common for the patient to cut ties with family and friends , as part of the loss of interest in life itself. To treat this disease you can use therapy and drugs.
Other uses of the term exogenous
According to geology , an exogenous phenomenon (or an exogenous force ) develops on the surface of the planet. They do not take place, therefore, inside the Earth.
Exogenous energy , finally, does not come from inside the body, unlike endogenous energy (generated through diet).
