Summary
In a study, 35 percent of recently deceased people with schizophrenia had damage in the brain’s subplate. No recently deceased people without schizophrenia had this kind of damage. The subplate damage must have occurred before the second fetal trimester. This is when the subplate controls the development of different connections in the brain.
Strongly Supported Conclusions
Subplate damage may have a role in causing schizophrenia.
Damage that occurs before a person is born may have a role in causing schizophrenia.
