Outline the neurodevelopmental hypothesis of the etiology of schizophrenia.
What will be an ideal response?
Ans: According to the neurodevelopmental hypothesis, an insult or negative event in the second trimester of pregnancy sets the stage for the incomplete development of the frontal lobe when the brain undergoes a period of reorganization during adolescence. Potential negative events during prenatal development that might contribute to schizophrenia include maternal infection or malnutrition; Vitamin D deficiency, for example, has been implicated in the eventual development of schizophrenia. During adolescence, these prenatal risk factors may be associated with enlarged ventricles and a loss of gray matter, especially in frontal and parietal areas of the brain.
