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...

Block Diagram Reduction01:22

Block Diagram Reduction

545
The process of deriving the transfer function of a control system often involves reducing its block diagram to a single block. This simplification can be achieved through a series of strategic operations, including relocating branch points and comparators. These operations preserve the overall function of the system while allowing for easier manipulation and combination of blocks.
The first step in this process is the identification and relocation of a branch point. A branch point, where a...

Oxymercuration-Reduction of Alkenes

9.3K
Oxymercuration–reduction of alkenes is one of the major reactions converting alkenes to alcohols. It involves the hydration of alkenes with mercuric acetate in a mixture of tetrahydrofuran and water, forming an organomercury adduct. This is followed by a demercuration step in which the adduct is reduced to an alcohol using sodium borohydride.

Phase I Reactions: Reductive Reactions01:27

Phase I Reactions: Reductive Reactions

582
Phase I biotransformation reductive reactions are chemical processes that modify drugs by introducing or revealing polar functional groups via reduction. Enzymes called reductases catalyze these reactions, playing a pivotal role in drug metabolism by transforming lipophilic drugs into more polar, water-soluble metabolites for easy excretion. An essential type of reductive reaction is the carbonyl group reduction, where aldehydes and ketones are reduced to alcohols. An example is the...

Esters to Alcohols: Hydride Reductions01:17

Esters to Alcohols: Hydride Reductions

4.7K
Esters are reduced to primary alcohols when treated with a strong reducing agent like lithium aluminum hydride. The reaction requires two equivalents of the reducing agent and proceeds via an aldehyde intermediate.
Lithium aluminum hydride is a source of hydride ions and functions as a nucleophile. The mechanism proceeds in three steps. Firstly, the nucleophilic hydride ion attacks the carbonyl carbon of the ester to form a tetrahedral intermediate. Subsequently, the carbonyl group re-forms,...

Summary

Epilepsy surgery may reduce apathy in patients, though the direct link is unclear. The Frontal Systems Behavior Scale (FrSBe) shows promise for measuring behavioral changes after epilepsy surgery.

Area of Science:

  • Neuroscience
  • Behavioral Science
  • Neurosurgery

Background:

  • Epilepsy surgery can alter patient behavior, sometimes causing new neuropsychiatric symptoms or alleviating pre-existing ones.
  • Standard psychiatric diagnostic criteria may not accurately assess behavioral changes in epilepsy patients.
  • Frontal-subcortical dysfunction is a key concern in post-surgical epilepsy patients.

Purpose of the Study:

  • To assess the feasibility of using the Frontal Systems Behavior Scale (FrSBe) to measure behaviors linked to frontal-subcortical dysfunction.
  • To evaluate behavioral changes in patients who underwent surgical intervention for medically refractory epilepsy.

Main Methods:

  • Twenty-three epilepsy surgery patients and their family informants completed the FrSBe.
  • The FrSBe assesses executive dysfunction, disinhibition, and apathy before and after surgery.
  • Both patient and informant ratings were collected for pre- and post-surgical behaviors.

Main Results:

  • Informants reported a significant reduction in apathy post-surgery compared to executive dysfunction or disinhibition.
  • A trend suggested apathy reduction after right hemisphere resections.

Conclusions:

  • Epilepsy surgery patients exhibited reduced apathy, but the causal link to surgery requires further investigation.
  • The FrSBe appears useful for studying behavioral alterations following epilepsy surgery.
  • Dimensional scales like the FrSBe are recommended for future research on post-surgical behavioral changes.
