Pharmacogenetic studies of psychotropic drug response have focused on determining the relationship between variations in specific candidate genes and the positive and adverse effects of drug treatment. Approximately, 18% of neuroleptics are substrates of CYP1A2 enzymes, 40% of CYP2D6, and 23% of CYP3A4; 24% of antidepressants are substrates of CYP1A2 enzymes, 5% of CYP2B6, 38% of CYP2C19, 85% of CYP2D6, and 38% of CYP3A4; 7% of benzodiazepines are substrates of CYP2C19 enzymes, 20% of CYP2D6, and 95% of CYP3A4. 10-20% of Western populations are defective in genes of the CYP superfamily; and the pharmacogenomic response of psychotropic drugs also depends on genetic variants associated with dementia. Prospective studies with anti-dementia drugs or with multifactorial strategies have revealed that the therapeutic response to conventional drugs in Alzheimer’s disease is genotype-specific. The disease-modifying effects (cognitive performance, biomarker modification) of therapeutic intervention are APOE-dependent, with APOE-4 carriers acting as the worst responders (APOE-3/3 \u003e APOE-3/4 \u003e APOE-4/4). APOE-CYP2D6 interactions also influence the therapeutic outcome in patients with dementia. \n","tracks":[{"project":"NEUROSES","denotations":[{"id":"T7","span":{"begin":13,"end":23},"obj":"PATO_0001510"},{"id":"T8","span":{"begin":154,"end":157},"obj":"CHEBI_29447"},{"id":"T9","span":{"begin":154,"end":157},"obj":"CHEBI_45296"},{"id":"T10","span":{"begin":154,"end":157},"obj":"CHEBI_29426"},{"id":"T11","span":{"begin":154,"end":157},"obj":"CHEBI_29441"},{"id":"T12","span":{"begin":154,"end":157},"obj":"CHEBI_29425"},{"id":"T13","span":{"begin":154,"end":157},"obj":"CHEBI_18022"},{"id":"T14","span":{"begin":241,"end":248},"obj":"PATO_0001517"},{"id":"T15","span":{"begin":368,"end":372},"obj":"CHEBI_23888"},{"id":"T16","span":{"begin":929,"end":934},"obj":"CHEBI_23888"},{"id":"T17","span":{"begin":1029,"end":1034},"obj":"CHEBI_23888"},{"id":"T18","span":{"begin":406,"end":418},"obj":"CHEBI_35476"},{"id":"T19","span":{"begin":494,"end":509},"obj":"CHEBI_35469"},{"id":"T20","span":{"begin":614,"end":629},"obj":"CHEBI_22720"},{"id":"T21","span":{"begin":733,"end":742},"obj":"PATO_0000460"},{"id":"T22","span":{"begin":733,"end":742},"obj":"PATO_0001511"},{"id":"T23","span":{"begin":759,"end":762},"obj":"CHEBI_38559"},{"id":"T24","span":{"begin":1134,"end":1143},"obj":"CHEBI_59163"},{"id":"T25","span":{"begin":1218,"end":1226},"obj":"CHEBI_78059"}],"attributes":[{"subj":"T7","pred":"source","obj":"NEUROSES"},{"subj":"T8","pred":"source","obj":"NEUROSES"},{"subj":"T9","pred":"source","obj":"NEUROSES"},{"subj":"T10","pred":"source","obj":"NEUROSES"},{"subj":"T11","pred":"source","obj":"NEUROSES"},{"subj":"T12","pred":"source","obj":"NEUROSES"},{"subj":"T13","pred":"source","obj":"NEUROSES"},{"subj":"T14","pred":"source","obj":"NEUROSES"},{"subj":"T15","pred":"source","obj":"NEUROSES"},{"subj":"T16","pred":"source","obj":"NEUROSES"},{"subj":"T17","pred":"source","obj":"NEUROSES"},{"subj":"T18","pred":"source","obj":"NEUROSES"},{"subj":"T19","pred":"source","obj":"NEUROSES"},{"subj":"T20","pred":"source","obj":"NEUROSES"},{"subj":"T21","pred":"source","obj":"NEUROSES"},{"subj":"T22","pred":"source","obj":"NEUROSES"},{"subj":"T23","pred":"source","obj":"NEUROSES"},{"subj":"T24","pred":"source","obj":"NEUROSES"},{"subj":"T25","pred":"source","obj":"NEUROSES"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"NEUROSES","color":"#93b2ec","default":true}]}]}}
