  1. What are some biological factors that may contribute to the development of schizophrenia? a) Genetic predisposition, prenatal infections, brain abnormalities, neurotransmitter imbalances b) Genetic predisposition, prenatal stress, brain injuries, hormone imbalances c) Genetic predisposition, prenatal malnutrition, brain

inflammation, immune system dysregulation d) All of the above Answer: D. All of the above are possible biological factors that may contribute to the development of schizophrenia. Schizophrenia has a strong genetic component, with an estimated heritability of 80%. Prenatal infections, stress, malnutrition, and other environmental factors may increase the risk of schizophrenia by affecting brain development and maturation. Brain abnormalities in schizophrenia may include enlarged ventricles, reduced gray matter volume, and altered connectivity in various regions. Neurotransmitter imbalances in dopamine, glutamate, serotonin, and GABA may also play a role in schizophrenia symptoms. Additionally, schizophrenia may involve brain inflammation and immune system dysregulation, which may be triggered by infections, stress, or autoimmunity.

Answer: C. PTSD is characterized by persistent and intrusive symptoms of re-experiencing, avoidance, negative alterations in cognition and mood, and hyperarousal that last more than one month after the traumatic event. Re-experiencing symptoms include recurrent and distressing memories, nightmares, flashbacks, or emotional and physical reactions to reminders of the trauma.
