rts claim that mental illness is nothing but a brain disorder like other illnesses, and there are no causes of mental illness such as ill-fated or bad deeds in the past/previous life.
Analysis of the material (Corrigan & Watson, pp. 162-179, 2003) related to mental illness has indicated that mental illness has now become a usual notion in contemporary era, and most of the studies have specified that mental illness does not have a physical existence, and thus, it always required support of a theory or concept for its justification. For instance, during ancient and medieval periods, and even today in some parts of the globe, people relate magic, fate, witches, and unseen forces as causes of mental illness. Such perspective has increased the efforts of organizations and experts (Corrigan & Watson, pp. 162-179, 2003) to claim that mental illness is a brain disorder and that people with mental illness should acquire treatment accordingly rather than confront detestation, isolation, and magical interventions.
Further analysis has indicated that experts (Farmer, pp. 40-46, 2001) have related intoxication of brain, and particularly, syphilis of brain as the major cause of mental illness in humans. Although very few experts (Stein, pp. 37-41, 2004) have accepted this notion, however, introduction of recent technologies in medical science has resulted in efforts made to prove such intoxications. In psychology, experts (Nestler, pp. 61-68, 2008) believe that abovementioned intoxications enforce patients to confront certain disorders in their thinking patterns that justify the unpredictable behavior of people confronting mental illness. In addition, experts have indicated that usually all types of brain disorders cause alterations in thinking and behavior patterns similar to mental illness, and thus, mental illness is a brain disorder that has been able to influence an enormous number of experts and psychologists globally.
