A neurological disorder in which a subject perceives him- or herself as smaller than normal, while other objects appear larger and closer than normal. Causes can include epilepsy, psychoactive drugs, or migraines. Macropsia is the opposite of micropsia.
Example: A patient complaining of severe migraines also reports episodes in which everything in her environment looks huge and she feels tiny.
