metformin and Schizophrenia

metformin has been researched along with Schizophrenia in 56 studies

Metformin: A biguanide hypoglycemic agent used in the treatment of non-insulin-dependent diabetes mellitus not responding to dietary modification. Metformin improves glycemic control by improving insulin sensitivity and decreasing intestinal absorption of glucose. (From Martindale, The Extra Pharmacopoeia, 30th ed, p289)
metformin : A member of the class of guanidines that is biguanide the carrying two methyl substituents at position 1.

Schizophrenia: A severe emotional disorder of psychotic depth characteristically marked by a retreat from reality with delusion formation, HALLUCINATIONS, emotional disharmony, and regressive behavior.

Correlations Between Weight Changes and Changes in Eating Inventory (EI) and Food Craving Inventory (FCI) at 2 Weeks and 22 Weeks

To understand the drivers of weight gain as indicated by the correlation between weight changes and changes in the Eating Inventory (EI) and Food Craving Inventory (FCI). The EI is a 51-item inventory that measures dietary restraint, disinhibition, and perceived hunger. The FCI is a 28-item instrument measuring the frequency over the past month of general cravings and cravings for specific types of foods, namely: high fats, sweets, carbohydrates/starches, and fast-food fats. Correlations were computed on the combined treatment groups. (NCT00401973)
