Summary
Surgical treatment for post-traumatic epilepsy (PTE) can be effective, with temporal lobectomy showing outcomes similar to non-traumatic epilepsy. Neuromodulation devices like VNS and RNS offer variable seizure reduction for patients not suitable for resection.
Area of Science:
- Neurosurgery
- Epileptology
- Traumatic Brain Injury Research
Background:
- Post-traumatic epilepsy (PTE) is a significant complication of traumatic brain injury (TBI), affecting up to 20% of severe cases.
- PTE is often considered challenging to manage with surgical interventions.
Purpose of the Study:
- To evaluate the surgical treatment outcomes for patients with post-traumatic epilepsy.
- To assess the efficacy of different surgical approaches, including resection and neuromodulation.
Main Methods:
- Retrospective enrollment of 23 patients with a history of head injury undergoing epilepsy surgery.
- Outcomes assessed using Engel classification for resections and seizure frequency reduction for vagal nerve stimulator (VNS) and responsive neurostimulator (RNS) implantation.
Main Results:
- Temporal lobectomy (TL) in 14 patients resulted in 68.8% Engel I outcomes.
- VNS implantation in 7 patients yielded an average seizure reduction of 30.6%.
- Responsive neurostimulator (RNS) implantation in 3 patients showed limited seizure frequency reduction (9.6%).
Conclusions:
- Surgical outcomes for PTE patients undergoing TL are comparable to those with non-traumatic epilepsy.
- VNS and RNS provide variable seizure control for PTE patients unsuitable for surgical resection.

Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

02:24Predicting Reaction Outcomes
10.4K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

106.8K
Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

01:20Traumatic Memory
567
Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual...

01:24Epilepsy 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...

01:11Guidelines for Writing Outcome
3.7K
When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
