Summary
Electroconvulsive therapy (ECT) for depression is linked to a rise in body temperature, particularly after symptom remission. This suggests body temperature could be a biomarker for ECT effectiveness.
Area of Science:
- Neuroscience
- Psychiatry
- Medical Research
Background:
- Recent research indicates hyperthermia as an effective depression treatment.
- This study investigated the relationship between electroconvulsive therapy (ECT) and body temperature changes in depression patients.
Purpose of the Study:
- To test the hypothesis that electroconvulsive therapy (ECT), a proven depression therapy, is associated with an increase in body temperature.
- To explore the potential of body temperature as a biomarker for ECT efficacy.
Main Methods:
- Retrospective chart analysis of 33 participants treated for severe, recurrent depression with ECT.
- Collection of oral temperature recordings before and after the first and final ECT sessions.
- Statistical analysis using a paired t-test to compare temperature changes.
Main Results:
- No significant change in mean oral temperature was observed after the first ECT treatment.
- A significant increase in oral temperature from baseline was recorded after the final ECT treatment, coinciding with clinical depression remission (P < .009).
Conclusions:
- Clinical improvement in depression following ECT correlates with an elevated body temperature.
- Body temperature may serve as a potential biomarker for assessing the efficacy of ECT.
- This finding could extend to monitoring the effectiveness of antidepressant pharmacotherapies.

The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...

A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
