Understanding SSRIs

Selective Serotonin Reuptake Inhibitors (SSRIs) are a class of drugs commonly prescribed for depression and anxiety disorders. They subtly alter brain chemistry to improve mood and reduce anxiety.

SSRIs work by blocking the reuptake of serotonin, a neurotransmitter, into neurons. This increases serotonin levels in the brain's synaptic cleft, enhancing mood-regulating communication between neurons.

Serotonin impacts mood, emotion, and sleep. Low levels are linked to depression. SSRIs help normalize serotonin levels, thus diminishing depressive symptoms and improving emotional well-being.

Surprisingly, SSRIs don't yield immediate effects. Full benefits often take weeks. The initial mood lift is subtle as the brain gradually adjusts to the higher serotonin levels.

While effective for many, SSRIs can cause side effects: sexual dysfunction, weight gain, and sleep issues. Interestingly, some SSRIs can increase depression or anxiety initially before improving symptoms.

SSRIs can lead to neurogenesis—new neuron growth—in the hippocampus, which is linked to improved mood and cognitive function.
