Which of the following is a plausible explanation for how maternal influenza might lead to schizophrenia
later in life?
A) The flu virus frequently has long-term effects on the behavior of affected individuals; maternal
infection with influenza may result in an environment that is likely to trigger schizophrenia in the
susceptible individual.
B) Maternal antibodies could cross the placenta and interfere with brain development such that the risk
of developing schizophrenia is enhanced later in life.
C) The flu exposure may alter the fetal genes such that a susceptibility to schizophrenia is now part of
the child's genetic makeup.
D) The flu virus may lay dormant in the brain until adolescence when it becomes active and initiates the
degeneration that results in the symptoms of schizophrenia.
