Anti-anxiety agents work by ??,
altering levels of neurotransmitters
depressing central nervous system activity
blocking the neurotransmitter dopamine
improving the ability to focus on tasks
The correct answer and explanation is:
Correct Answer:
Altering levels of neurotransmitters
Explanation:
Anti-anxiety agents, also known as anxiolytics, work primarily by altering levels of neurotransmitters in the brain. Neurotransmitters are chemical messengers that transmit signals between nerve cells, influencing emotions, mood, and cognitive function.
One of the main neurotransmitters involved in anxiety regulation is gamma-aminobutyric acid (GABA). Many anti-anxiety medications, such as benzodiazepines (e.g., diazepam, lorazepam, and alprazolam), enhance the activity of GABA, which has an inhibitory effect on the nervous system. This leads to a calming effect, reducing feelings of stress and anxiety.
Other medications, like selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), also play a role in treating anxiety. These drugs increase the availability of serotonin and norepinephrine in the brain. Serotonin is known to regulate mood and emotional stability, while norepinephrine is linked to stress response. By increasing these neurotransmitters, SSRIs and SNRIs help alleviate symptoms of anxiety over time.
Why Other Options Are Incorrect:
- Depressing central nervous system activity – While some anti-anxiety drugs do have a sedative effect, not all of them work by depressing the central nervous system. SSRIs and SNRIs, for example, regulate neurotransmitters without directly sedating the brain.
- Blocking the neurotransmitter dopamine – Dopamine-blocking drugs are primarily used for schizophrenia and psychosis, not anxiety.
- Improving the ability to focus on tasks – Medications for ADHD, like stimulants, improve focus but are not anti-anxiety agents.
Now, I’ll generate an image to visually represent the effects of anti-anxiety agents.
Here is the generated image illustrating the effects of anti-anxiety medications on neurotransmitters in the brain. It visually represents how these drugs enhance neurotransmitter activity, particularly GABA and serotonin, to produce a calming effect.
