Since most patients with schizophrenia, mania, depression and other psychiatric disorders have their onset in young adulthood, many family members are worried about whether the patients can get married and whether they will inherit. Psychiatric patients can get married, but there are two conditions: one is that the mental illness has been cured, and the patient can adapt to the ritual life and resume normal work and study. Whether the patient is cured or not should be determined by the South psychiatrist. The other is that there is no relapse for more than one year. It is worth noting that before the patient gets married, the other party should be made aware that the patient has suffered from mental illness, so that they can combine on a completely voluntary basis after careful consideration, which is good for the life, work and stability of the mental patient after marriage. Many people conceal the fact of their illness from each other before they get married, and after marriage, they are afraid to take their medication in front of their loved ones, so they reduce their medication to stop. This has led to a relapse of the disease, which is a painful lesson: the marriage law also has a corresponding provision, married during the onset of the disease or concealed from the other party and then relapse after marriage can be regarded as an invalid marriage, and bring great trauma to both parties. In the following cases, mentally ill persons cannot marry: Patients with schizophrenia, manic-depressive disorder or other severe mental illnesses who are in the midst of their illness should be prohibited from marrying. This is because they have lost their senses during the illness. It is often difficult for them to take care of their own lives, and they may even endanger social security. So, let such patients get married, not only for the patient himself is not good, but also to the other party will cause misfortune. Secondly, although the onset of the period has passed, but the psychiatric symptoms have not been completely remitted or in the treatment of patients can not get married. Because at this time the patient’s ability to withstand setbacks in life and marriage is still poor, often making them in love, or the wedding night, or soon after the wedding aggravated, hospitalized again. Therefore, those who want to treat mental illness with a rush of happy events, or worry about their children suffering from mental illness, affecting lifelong events, and give them a hasty search for objects, hasty marriage is wrong, not only difficult to achieve the purpose, and even tragedy will result. Therefore, the marriage of psychiatric patients, family members must be careful and reasonable to give a solution to the problem of heredity, the occurrence of mental illness is indeed related to heredity, but it is not entirely determined by heredity, but a variety of factors. Therefore, psychiatric patients who meet the two conditions mentioned above and are married should also go to their doctor to consult the genetic risk level, and if the risk level is too high, it is better not to have children: for patients in the onset of schizophrenia, it is temporarily not advisable to have children. Some psychotropic drugs have teratogenic side effects. It is also inadvisable to have children while taking medication, and the decision should be made based on the individual’s condition, the type of medication being taken, and family history of mental illness.
