Quiz — Test Your Understanding

Question 1 of 8
What unexpected side effect of the rheumatoid arthritis drug Remicade helped scientists connect inflammation to mood?
  • A. It caused patients to experience sudden euphoria and cheerfulness.
  • B. It permanently cured the patients' underlying clinical depression.
  • C. It worsened depressive symptoms by temporarily increasing cytokine levels.
  • D. It made patients lethargic and antisocial to conserve energy.
Question 2 of 8
How did René Descartes' philosophy of Cartesian dualism negatively impact modern medicine's approach to depression?
  • A. It suggested that the pineal gland was the sole cause of all mental illnesses.
  • B. It created a strict divide between physical and mental health, discouraging holistic treatments.
  • C. It promoted the idea that depression is strictly a chemical imbalance in the brain.
  • D. It led to the over-prescription of anti-inflammatory drugs for psychological issues.
Question 3 of 8
According to the book, what is a major flaw in the widely accepted serotonin theory of depression?
  • A. SSRIs like Prozac actually decrease serotonin levels in the brain over time.
  • B. The theory only applies to depression caused by autoimmune diseases.
  • C. Serotonin is only found in the gut, not in the brain's nerve cells.
  • D. No studies have ever proven that depressed people actually have lower levels of serotonin.
Question 4 of 8
How does bodily inflammation affect the brain, despite the presence of the Blood-Brain Barrier (BBB)?
  • A. The BBB completely dissolves when C-reactive protein (CRP) levels reach a certain threshold.
  • B. Cytokines trigger the vagus nerve to send a signal to the brain, kick-starting its own inflammatory response.
  • C. Macrophages from the gut migrate directly into the brain to destroy healthy nerve cells.
  • D. The brain shrinks the BBB to allow excess serotonin to escape into the bloodstream.
Question 5 of 8
What happens to the base protein tryptophan in the brain during an inflammatory response?
  • A. It is converted into kynurenine, which is toxic to nerve cells and reduces serotonin production.
  • B. It rapidly multiplies, causing swelling and stiffness in the brain's emotional network.
  • C. It is used by microglia to repair nerve connections damaged by macrophages.
  • D. It blocks the vagus nerve to prevent further inflammation from reaching the spleen.
Question 6 of 8
Which of the following is identified as perhaps the biggest contributor to chronic inflammation and a well-known trigger of depression?
  • A. A lack of dietary tryptophan.
  • B. Overactive lymphocytes in the lymph nodes.
  • C. Acute or chronic stress, including minor social stressors.
  • D. The overuse of SSRI medications.
Question 7 of 8
From an evolutionary perspective, why might genes that trigger inflammation and depressive behaviors have been advantageous to our ancestors?
  • A. Depression made early humans more aggressive and better at hunting large prey.
  • B. Lethargy conserved energy for fighting infections, and social withdrawal prevented the spread of disease.
  • C. High cytokine levels allowed ancestors to survive longer periods without food or water in the savannah.
  • D. Sickness behavior helped early humans form stronger emotional bonds and alliances.
Question 8 of 8
Why aren't anti-inflammatory drugs currently licensed as a standard treatment for depression?
  • A. Pharmaceutical companies have proven they are entirely ineffective for mental health.
  • B. They cause the blood-brain barrier to become completely impermeable.
  • C. There is not enough evidence to prove their benefits outweigh side effects like gut damage or blood thinning.
  • D. They permanently deactivate the vagus nerve, leading to cognitive impairments.
