Summary
Selective serotonin reuptake inhibitors (SSRIs) can cause hyponatremia, a dangerous drop in sodium levels. This case highlights escitalopram-induced SIADH, emphasizing cautious use and electrolyte monitoring in depressed patients.
Area of Science:
- Neuroscience
- Endocrinology
- Pharmacology
Background:
- Selective serotonin reuptake inhibitors (SSRIs) are widely prescribed for depression.
- Hyponatremia, a rare complication, can occur during SSRI therapy.
- Syndrome of Inappropriate Antidiuretic Hormone (SIADH) is a known cause of hyponatremia.
Observation:
- A 54-year-old female with hypertension presented with a seizure episode.
- The patient was recently prescribed escitalopram for depression.
- Severe hyponatremia was diagnosed, attributed to SSRI-induced SIADH.
Findings:
- Escitalopram, an SSRI, was identified as the causative agent for SIADH.
- The patient's hyponatremia was a direct result of escitalopram intake.
- This case adds to the limited reports of escitalopram-induced SIADH.
Implications:
- All SSRIs, including escitalopram, carry a risk of causing SIADH.
- Caution is advised when prescribing SSRIs, particularly escitalopram.
- Regular electrolyte monitoring is crucial in patients on SSRIs, especially the elderly.

Global Climate Change
29.1K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Empathy

Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.
