Reverse culture shock
Reverse culture shock (also known as "re-entry shock" or "own culture shock") may take place—returning to ones home culture after growing accustomed to a new one can produce the same effects as described above. These are results from the psychosomatic and psychological consequences of the readjustment process to the primary culture. The affected person often finds this more surprising and difficult to deal with than the original culture shock. This phenomenon, the reactions that members of the re-entered culture exhibit toward the re-entrant, and the inevitability of the two are encapsulated in the following saying, also the title of a book by Thomas Wolfe: You Cant Go Home Again. Reverse culture shock is generally made up of two parts: idealization and expectations. When an extended period of time is spent abroad we focus on the good from our past, cut out the bad, and create an idealized version of the past. Secondly, once removed from our familiar setting and placed in a foreign one we incorrectly assume that our previous world has not changed. We expect things to remain exactly the same as when we left them. The realization that life back home is now different, that the world has continued without us, and the process of readjusting to these new conditions as well as actualizing our new perceptions about the world with our old way of living causes discomfort and psychological anguish. Outcomes
There are three basic outcomes of the adjustment phase:
Some people find it impossible to accept the foreign culture and to integrate.
The chemicals and structures that make up the brain have similarities across different people, but they vary in certain enzymes and receptors. These variations are not usually enough to cause a problem, but occasionally they do. For example, if a person has a mutation in a gene that creates the sodium channel (a part of the neuron required for firing) it makes it easier for neuronal firing to get out of control. An infection of the brain (encephalitis) can also be a contributing factor. Although this sort of infection is uncommon it can be due to a virus, bacterium, or (very rarely) fungus. If a seizure happens during the infection itself, the person most likely doesnt have epilepsy but has "symptomatic seizures" or seizures occurring because of a known injury to the brain. Once the infection is stopped the seizures will stop. Another more common infection is "meningitis", infection of the membranes surrounding the brain. Since this infection does not directly involve the brain it might not appear as a possible cause of epilepsy, but has been shown that meningitis can cause epilepsy, which would give rise to the possibility of developing epilepsy partialis continua. These infections are most likely to result in epilepsy when they occur at an early age. Problems with brain development can also be a factor. The brain undergoes a complicated process during development in which neurons are born and must travel to the surface of the brain. Here they wind up carefully placed in six distinct layers of the cerebral cortex.
