One problem with the chart where do mood stabilizers like Lithium and Depakote fit into this chart I ask because psychoactive substances should be a superset of psychiatric medications which has 4 major drug classes stimulants depressants anti psychotics and mood stabilizers So shouldn t this chart have 5 circles I know it won t make the chart any simpler but I d like to see this article and the Psychiatric Meds and Psychopharmacology articles work more closely together
