The Psycho-env corpus is produced to facilitate knowledge discovery on correlating mental diseases and environmental factors. It is a database manually curated from the published studies including research articles, clinical trials and case reports.
As with other diseases, it has been established that mental illnesses are influenced in their origins and pathology by environmental factors. For example, it has been found that higher rates of schizophrenia occur in people of Caribbean origin than ethnically similar white people living in the UK [1]. To date, no complete list of environmental factors for all existing mental illnesses has been compiled that can be used for patient screening and planning treatment strategies [2].
