This interplay between genetics and environment contributes to the variability of cognitive symptoms observed in individuals with schizophrenia. For instance, some individuals might display severe cognitive deficits due to a combination of their genetic makeup and adverse environmental experiences, while others with similar genetic backgrounds may experience milder cognitive dysfunction if their environmental influences are less impactful.
