Chronic Fatigue Syndrome Practice Test

The class of medications that increases serotonin availability and may help with sleep issues in Chronic Fatigue Syndrome (CFS) is SSRIs, or selective serotonin reuptake inhibitors. These medications work by blocking the reabsorption (reuptake) of serotonin in the brain, which helps to increase its availability. This boost in serotonin levels can improve mood and may also have a positive effect on sleep quality.

CFS is often associated with mood disturbances, anxiety, and sleep problems, making SSRIs a potentially helpful option for managing these symptoms. By enhancing serotonin signaling, SSRIs can contribute to better sleep and overall emotional well-being, which are crucial for individuals dealing with the debilitating fatigue and associated symptoms of CFS.

The other medication classes listed do not primarily function to increase serotonin levels or are not directly associated with improving sleep in the context of CFS. For example, beta blockers are typically used for cardiovascular conditions and do not have a beneficial effect on serotonin. Muscle relaxers are used to relieve muscle tension and spasms, with little evidence supporting their efficacy for serotonin modulation. Antihistamines are primarily used to alleviate allergy symptoms and can sometimes induce drowsiness, but they do not address the underlying serotonin imbalances that may be relevant in C
