###Human: Will stopping psychiatric medications change the behavior? ###Assistant: Hi. The diagnosis of mood disorders is not easily made at the age of 8 years but if you were given that diagnosis then there must have been a detailed assessment of yours. Coming to your questions, our mood, thoughts, and behavior is controlled by certain chemicals in our brain like Dopamine and Serotonin. The imbalance of these chemicals is responsible for inducing the mood and other psychiatric disorders. Risperidone and Lamotrigine both balance these chemicals in your brain and keep your mood in check. Yes, decreasing the dose of medicines without your psychiatrist's supervision worsen the problem. I would advise you to get back to your psychiatrist, he will adjust your doses according to the current state.
