According to NCBI, there is not a cure for mental health issues, but they can usually be treated effectively to minimize the symptoms and allow the individual to function in work, school, or social environments. To begin treatment, an individual needs to see a qualified mental health professional. The first thing that the doctor or other mental health professional will do is speak with the individual to find out more about his or her symptoms, how long the symptoms have lasted, and how the person’s life is being affected. The physician will also do a physical examination to determine whether there are other health problems. For example, some symptoms (such as emotional swings) can be caused by neurological or hormonal problems associated with chronic illnesses such as heart disease, or they can be a side effect of certain medications. After the individual’s overall health is evaluated and the condition diagnosed, the doctor will develop a treatment plan. Treatment can involve both medications and psychotherapy, depending on the disease and its severity.
I hope this helped you understand whether there is a cure for mental health.
