It cannot. Many people with mental disorders go to the hospital hoping to rely solely on psychological counseling or psychotherapy to solve their problems. This view is wrong, and it exaggerates the role of psychological counseling and psychotherapy. This is because, except for normal people who encounter specific troubles and can do psychological counseling, and some patients with mild neurological disorders can do simple psychotherapy, all patients with severe mental illness and moderate or above neurological disorders cannot rely on simple psychological counseling and psychotherapy to solve their problems, and even cause delays. According to the latest regulations of the World Health Organization, psychotherapy is only applicable to very mild symptoms, and formal psychotherapy should be immediately transferred to medication once there is no effect after 12 weeks. After long-term application of such drugs, sudden discontinuation or abrupt reduction will result in a series of uncomfortable symptoms, commonly irritability, temper, sweating, nausea, loss of appetite, insomnia, panic attacks, headache, diarrhea, palpitations, myalgia, etc. Even seizures can occur, and in severe cases, hallucinations and delusions, and even death can occur secondary to them.
