The functions of the mind are complex through the different states of mind functioning and malfunctioning. This brings us to this three terms, psychotherapy, psychopathology and Mind Body Problem. Insanity and sanity as well as the role played by the mind as viewed by psychology helps us define and ascertain such differences (Seligman & Csikszentmihalyi,2000). The behavioral view of mind functioning holds that all mental processes are correlated to physical phenomena meaning mental malfunctioning is due to physical disorder as per the medical model theory of psychology. Correction of such mental disorders is through correct diagnosis. Chemical abnormalities such as low serotonin in depression and mood disorders same to physical disorders such as vitamin deficiencies and organ problems are hard to correct. Patient tend to feel specific pain or disorder in certain somatic disorders with no related physical cause example anxiety disorders that come as a result of improper breathing techniques and imbalance in neurotransmitters. Side effects of medications and interaction with certain medications cause abnormal functioning and probable misdiagnosis or drug prescription. Somatic disorders for instance, patients tend to feel pain or discomfort yet there is no evidence of physical cause therefore hard to establish the cause.

Physicians call this a mental processes but not a problem with the patient’s body as many would think. It does not involve the brain in most cases. A psychologists is normally required at this point. Somatoform disorders are mostly caused by the problems in the mind or cases such as hypochondria, post dramatic stress disorder, where a person may just choose to be sick. Neurotic disorders arise from lesser stress disorders such as family, divorce and no physical reasons at all. Phobia and myosphobia are some of the conditions that make some people act disorderly.

     Severe mental illness is a serious one since it shortens the victims’ lifespan. I second the fact that it is difficult to treat mental disorders that involves problems related to organs. As a result of this, physical illness leads to mortality. Evidences indicate that people with severe mental illness are less likely to receive care regarding these diseases at a standard level.

     Medications may also have side effects. There is need for improvement to aid people with mental disorders. Mental disorders also make a victim vulnerable to physical health problems. The mortality rate is alarming and this calls for an immediate action because the problem medical comorbidities are still on the rise at a constant rate. Kazdin and Blase confirmed that there is need for interventions (23).

YesterdayOct 20 at 9pmManage Discussion EntryVictor and Darlene,
     You both bring up great points into the mental illness causes and treatments.  Victor, you mentioned Chemical abnormalities such as low serotonin being the cause for depression.  There are some things a person can do besides medication to increase serotonin.  Exercise is known to increase serotonin. Eun-Sang et al., (2017) studied this in rats and found an increase in serotonin after exercise.  
Relaxation techniques and  music therapy, are other recommendations for treatment of certain mental illnesses. According to Clute, (2017).  Although these techniques are not evidence based some clinicians use them and have positive results.
The behavioral view of mind functioning holds that all mental processes are correlated to physical phenomena meaning mental malfunctioning is due to physical disorder 
I must disagree with the statement you listed (Victor ) as the behavioral view of mind.  I do not agree that all mental processes are correlated to physical phenomena.  I do believe that a physical disorder can contribute to some mental disorders but not all.  Example: if a person loses a limb such as an arm, this can cause the individual to experience depression and or anxiety.
