Patient: Description of condition (onset, main symptoms, hospital visited, etc.): At the end of December last year, my child suddenly became emotionally disturbed due to academic pressure and conflicts among classmates, and came to the brain hospital the next day. The doctor prescribed Opi, first half a capsule, but after taking it regularly, he felt no effect. After half a month, the child’s behavior became more and more delayed and he lost interest in everything. His body was stiff and his eyes were dull. We parents were so anxious that we kept on seeking medical advice from specialists. Later on, we switched to Boswellin, Antan, Sulbactam, and Propoxur. On Feb. 7, we went to see Dr. Yao, who understood the condition carefully. He re-prescribed quetiapine tablets and lorazepam. Is there a necessary connection between the child’s current situation and poor cerebellar development? What is a transient mental illness? Are the child’s current symptoms a function of the medications? How long will it take for the child to change to these two medications? Nanjing Brain Hospital Psychiatric Department Yao Zhijian: 1. The child’s current situation is related to poor brain development, not only with cerebellar development, but also with the function of other brain areas. Your child’s cerebellar structure is already significantly poorly developed and clinically shows abnormalities in movement coordination and other aspects. The MRI structural phase does not reflect the functional level of the brain, and other brain regions may not show significant structural abnormalities at the current level of technology, but the clinical performance of brain function is not good. The term “transient psychosis” is not a professional term, but a colloquial expression for transient mental disorders, which have many causes. 3. Your child’s current symptoms are both side effects of the medication and symptoms of the disease itself. 4. Whether these two drugs are effective or not needs to be observed, and it is recommended to review them after 2 weeks. 5, the child is now more than 13 years old and grows small, after the holiday it is recommended to continue child psychiatric consultation.
