Epilepsy and Seizures: Overview01:24

Epilepsy and Seizures: Overview

1.2K
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...

Operational Amplifiers01:17

Operational Amplifiers

1.9K
The operational amplifier, often referred to as an op-amp, is a multifaceted building block of a circuit. This electronic component functions like a voltage-controlled voltage source and can also be used to create a voltage- or current-controlled current source. The design of an operational amplifier enables it to execute mathematical operations when external components like resistors and capacitors are linked to its terminals. An op-amp has the capacity to sum signals, amplify a signal,...

Nursing Process for Patient and Caregiver Teaching III: Evaluation and Documentation

2.5K
Evaluation of the teaching process enables the nurse to determine if the patient's learning needs were met and if training was effective. If the expected outcomes are not met, the care plan is revised, and additional education or reinforcement is provided. Nurses can ask questions after the session or obtain feedback to assess the patient's understanding of the topic.
Nurses can use several methods to evaluate patient outcomes. For example, oral questions can assess cognitive learning,...

Vector Operations01:20

Vector Operations

2.2K
Vectors are physical quantities that have both magnitude and direction. The vector operations include addition, subtraction, and scalar multiplication.
A vector multiplied by a scalar value is called scalar multiplication. The result obtained is a new vector with a different magnitude. If the scalar is positive, the direction of the vector remains the same, but if it is negative, the direction of the vector is reversed. For example, the product of the mass and velocity yields the momentum.

Operant Conditioning01:21

Operant Conditioning

2.8K
Operant conditioning, a key concept in behavioral psychology, involves using reinforcement and punishment to alter the likelihood of a behavior being repeated. B.F. introduced this type of conditioning. Skinner focused on voluntary behaviors and the consequences that follow them, influencing whether these behaviors will be strengthened or diminished.
Reinforcement in operant conditioning can be positive or negative, both of which serve to increase the likelihood of a behavior. Positive...

Modes of Operations of BJT01:21

Modes of Operations of BJT

2.0K
A Bipolar Junction Transistor (BJT) is a versatile component in electronics, functioning in four distinct modes based on the biasing of its junctions: active, saturation, cut-off, and inverted modes.
Active Mode: The most common mode for amplification, the active mode features a forward-biased emitter-base junction and a reverse-biased base-collector junction. This setup enables electrons to be injected from the emitter to the base while blocking the majority carriers at the collector. The...

Summary

Inconclusive investigations and multifocal epilepsy were primary reasons for epilepsy surgery rejection. Patient refusal and cognitive risks also influenced decisions, with cognitive decline concerns rising over time.

Area of Science:

  • Neurology
  • Neurosurgery
  • Epileptology

Background:

  • Epilepsy surgery offers a curative option for drug-resistant epilepsy.
  • Presurgical evaluation is crucial to identify suitable candidates and predict outcomes.
  • Understanding reasons for non-surgical candidacy is vital for optimizing patient care pathways.

Purpose of the Study:

  • To identify and analyze the reasons why patients do not proceed to epilepsy surgery after presurgical evaluation.
  • To examine trends in these reasons over a 26-year period.

Main Methods:

  • Retrospective cohort study of 401 patients evaluated for epilepsy surgery (1990-2016).
  • Categorization of reasons for non-surgical candidacy.
  • Statistical comparison of categorical variables using Chi-square tests.

Main Results:

  • Inconclusive investigations (34.4%) and multifocal seizure onset (20.0%) were the leading reasons for rejection.
  • Increased consideration of postoperative cognitive decline risk in recent years.
  • Patient or caregiver refusal accounted for 14.2% of rejections.

Conclusions:

  • Inconclusive evaluations and multifocal epilepsy remain the principal barriers to epilepsy surgery.
  • The proportion of patients declining surgery was relatively low compared to other studies.
  • Evolving criteria, such as cognitive risk, impact surgical candidacy over time.
