Serotonin imbalances can cause which disorders?

• A. Depression and OCD
• B. ADHD and Autism
• C. Schizophrenia and bipolar
• D. Parkinson's disease

Answer: (A)

Serotonin helps regulate mood, anxiety, and impulse control. When serotonin signaling is out of balance, mood can become depressed and intrusive thoughts or compulsive behaviors can emerge. Depression is classically linked to reduced serotonin activity, and medications that boost serotonin signaling (SSRIs) are among the most effective treatments for many people. Obsessive-compulsive disorder is also strongly associated with serotonin dysregulation, which is why SSRIs are a primary pharmacological approach for OCD, often at higher doses or longer trial periods to achieve benefit. Other disorders listed involve different neurochemical systems or more complex etiologies. ADHD and autism are more closely tied to dopamine and norepinephrine dynamics and other factors. Parkinson’s disease stems largely from dopaminergic neuron loss. Schizophrenia and bipolar disorder involve a combination of dopaminergic, glutamatergic, and other system changes, with serotonin playing a modulatory role but not as the central driver in the same way as depression and OCD.
