It causes many problems in every aspect of one’s life and needs to be considered. Its causes and treatments need to be laid out for better understanding. (Nordqvist, March)The prefrontal cortex is the area of the brain that allows human beings to evaluate situations, make rational decisions and control their emotions and desires. This part of the brain is still developing in adolescence and abusing it will have a very dire effect in the future. (Buljan, 2010)An addict is a person who is addicted. This person will have desires and cravings, in which he will urgently want to indulge, and usually, symptoms of withdrawal accompany this feeling if he does not get the substance he craves. There are several reasons for this disease. Genetics are suspected, and so is the environment, but the new explanation that has been discovered is that it is a brain disease. (Maureen C Nash, 2011)The roles of the reward mechanisms in the brain are suspected to be involved with this disease. Dopamine systems stimulate the brain when it receives a reward be it food or any other thing that the person likes. This is the only center of the brain that stimulates it, and no additional center has been found to cause addiction. Taking the substance that you have addicted to changes the wiring of your brain and you require special needs to fulfill your cravings. Dopamine is activated with the use of the substance or aspect that you are addicted to. and this is not a natural process, but a highly unnatural one as you make your brain accustomed to the aspects that it is usually not used to, but is in fact actually sensitive to. It not only arouses your brain and rewards it but the arousal it leads to is of abnormal nature.
