The invention claimed is: 1. A method for inhibiting phosphodiesterase 9 activity in a subject, comprising administering to the subject a therapeutically effective amount of 6-[4-methyl-1-(pyrimidin-2-ylmethyl)pyrrolidin-3-yl]-3-tetrahydropyran-4-yl-7H-imidazo[1,5-a]pyrazin-8-one, or a tautomer or a pharmaceutically acceptable acid addition salt thereof. 2. The method of claim 1 , wherein the subject has a neurodegenerative disorder selected from the group consisting of Alzheimer's disease, mental retardation, cognitive impairment associated with schizophrenia, attention-deficit/hyperactivity disorder, age-related cognitive decline, and substance-induced psychotic disorder. 3. The method of claim 2 , wherein the substance-induced psychotic disorder is psychosis induced by alcohol, psychosis induced by amphetamine, psychosis induced by cannabis , psychosis induced by cocaine, psychosis induced by hallucinogens, psychosis induced by inhalants, psychosis induced by opioids, or psychosis induced by phencyclidine. 4. A method for inhibiting phosphodiesterase 9 activity in a subject, comprising administering to the subject a therapeutically effective amount of a pharmaceutical composition comprising 6-[4-methyl-1-(pyrimidin-2-ylmethyl)pyrrolidin-3-yl]-3-tetrahydropyran-4-yl-7H-imidazo[1,5-a]pyrazin-8-one, or a tautomer or a pharmaceutically acceptable acid addition salt thereof, and one or more pharmaceutically acceptable carriers, diluents or excipients. 5. The method of claim 4 , wherein the subject has a neurodegenerative disorder selected from the group consisting of Alzheimer's disease, mental retardation, cognitive impairment associated with schizophrenia, attention-deficit/hyperactivity disorder, age-related cognitive decline, and substance-induced psychotic disorder. 6.
