Electroconvulsive Therapy01:30

Electroconvulsive Therapy

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early years,...
Increased Body Temperature01:25

Increased Body Temperature

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 response to an infection or illness.
Types of Fever01:25

Types of Fever

Fever can be triggered by several factors, including infections, nervous system disorders, certain cancers, blood diseases like leukemia, embolism, thrombosis, heatstroke, dehydration, surgical trauma, crushing injuries, and allergic reactions.
Here are the different types of fever:
Methods of reducing fever01:22

Methods of reducing fever

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Before understanding the types and patterns of fever, it is essential to know its phases.
Epilepsy and Seizures: Overview01:24

Epilepsy and Seizures: Overview

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Summary
This summary is machine-generated.

Fever after modified electroconvulsive therapy (MECT) is common early in treatment and linked to longer EEG seizure duration. Monitoring and managing fever risk is crucial during initial MECT sessions for patient safety.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Clinical Medicine

Background:

  • Fever is a potential adverse event following modified electroconvulsive therapy (MECT).
  • Understanding the incidence and risk factors for post-MECT fever is essential for patient safety and treatment optimization.

Purpose of the Study:

  • To characterize the incidence and features of fever occurring within 24 hours after MECT.
  • To identify independent risk factors associated with the development of post-MECT fever.

Main Methods:

  • Retrospective analysis of 3006 MECT sessions across 451 patients with psychiatric disorders.
  • Fever defined as axillary temperature ≥37.3 °C within 24 hours post-session.
  • Mixed-effects logistic regression used to assess associations between fever and session order, anesthetic regimen, demographics, and EEG seizure duration.

Main Results:

  • Patient-level fever incidence was 20.18%; session-level incidence was 3.89%.
  • Fever episodes were more frequent in the first two MECT sessions and predominantly low-grade.
  • Increased risk of fever was associated with earlier treatment sessions (first and second) and longer EEG seizure duration.

Conclusions:

  • Post-MECT fever is typically low-grade and more prevalent in the initial treatment phase.
  • Treatment session order and EEG seizure duration are significant independent predictors of post-MECT fever.
  • Balancing treatment efficacy with peri-procedural safety is critical, especially during early MECT stages.
