Final answer:
Selective serotonin reuptake inhibitors (SSRIs) are a common treatment for depression, functioning by increasing the availability of serotonin in the synaptic cleft, which is crucial for mood regulation. option d is the correct answer.
Step-by-step explanation:
One of the most common treatments for depression is a category of drugs called SSRIs, or selective serotonin reuptake inhibitors. These medications work by blocking the reuptake of serotonin into the presynaptic neuron, thus increasing the availability of serotonin in the synaptic cleft. Because depression has been linked with reduced serotonin levels, SSRIs enhance the effect of serotonin by allowing it to remain active in the synaptic cleft for longer durations, which can contribute to improved mood and emotional regulation over time.
One of the most common treatments for depression is a category of drugs called SSRIs (Selective Serotonin Reuptake Inhibitors). SSRIs work by increasing the availability of serotonin in the brain. Serotonin is a neurotransmitter that affects mood and is often found to be lower in individuals with depression. By blocking the reuptake of serotonin, SSRIs allow for more serotonin to remain in the synaptic cleft, enhancing its function and alleviating symptoms of depression.
