Answer to Question 1

Answer: Twin studies indicate a high degree of concordance between identical and fraternal twins. Panic attacks are effectively treated using benzodiazepine drugs that facilitate GABA, whereas anxiety is induced by antagonism of GABA receptors.

Answer to Question 2

Answer: Amphetamine causes the dopamine transporter to run in reverse, resulting in the spillage of dopamine into the synapse. Administration of amphetamine can evoke symptoms of paranoid psychosis. Antipsychotic drugs, in contrast, relieve the positive symptoms of schizophrenia.
