2. Figure 13.1 Diagnostic Classifications in DSM-5
Each of the more than 260 psychological disorders described in DSM-5 has specific criteria that must be met for a person to be diagnosed with that disorder. Although the DSM has been criticized over the years, it serves several important roles in mental healthcare. For example, anyone who seeks treatment for mental illness and who wishes to have the treatment covered by insurance must receive a DSM diagnosis. Moreover, standardized diagnoses allow clinicians, such as a psychologist and a psychiatrist, to communicate with each other about a patient. Additionally, diagnoses provide a structure that allows researchers to design studies that can be replicated by other people. Shown here is a list of the major diagnostic classifications in DSM-5. Every diagnosis falls in one of these categories.

3. The chart on the left shows the median age of onset for common categories of mental disorders in the National Comorbidity Survey Replication (NCS-R). While the onset of anxiety, posttraumatic stress, and obsessive-compulsive disorders or impulse control disorders tends to occur in the preteen years, the onset of depressive and bipolar disorders typically occurs around age 30, well into young adulthood. The chart on the right shows the lifetime prevalence for the same mental disorder categories. The NCS-R reconfirmed that the lifetime prevalence of experiencing a mental disorder is almost one out of two.

16. Figure 13.6 The Risk of Developing Schizophrenia Among Blood Relatives
The risk percentages shown here reflect the collective results of about 40 studies investigating the likelihood of developing schizophrenia among blood relatives. As you can see, the greatest risk occurs if you have an identical twin who has schizophrenia (48 percent lifetime risk) or if both of your biological parents have schizophrenia (46 percent lifetime risk). However, environmental factors, as well as genetic ones, are involved in the development of schizophrenia.

17. Figure 13.7 The Finnish Adoptive Family Study of Schizophrenia
In the Finnish Adoptive Family Study, psychiatrist Pekka Tienari and his colleagues (1994, 2006) tracked the mental health of two groups of adopted individuals: one group with biological mothers who had schizophrenia and a control group whose biological mothers did not have schizophrenia. This graph shows the strong influence of the adoptive family environment on the development of serious mental disorders.
