Lateralized Periodic Discharges: A Literature Review
1Department of Neurology, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, Massachusetts, U.S.A.
Summary
This review covers lateralized periodic discharges (LPDs), an EEG pattern. It details their causes, symptoms, and controversies, offering future research directions for these important neurological findings.
Area of Science:
- Neurology
- Neurophysiology
Background:
- Lateralized periodic discharges (LPDs), also known as periodic lateralized epileptiform discharges (PLEDs), are a distinct EEG pattern.
- Understanding LPDs is crucial for diagnosing and managing various neurological conditions.
Purpose of the Study:
- To provide a comprehensive literature review on LPDs.
- To discuss the history, terminology, etiologies, pathophysiology, clinical symptoms, and imaging of LPDs.
- To examine controversies regarding LPDs and seizures, and to suggest future research avenues.
Main Methods:
- Literature review of studies on LPDs.
- Synthesis of information on LPDs from various sources.
- Analysis of current controversies and future research needs.

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

As early chemists discovered more elements, they realized that various elements could be grouped by their similar chemical behaviors. One such grouping includes lithium (Li), sodium (Na), and potassium (K). All of these elements are shiny, conduct heat and electricity well, and have similar chemical properties. A second grouping includes calcium (Ca), strontium (Sr), and barium (Ba), which also are shiny, good conductors of heat and electricity, and have chemical properties in common. However,...

The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in the outer shells of these elements is observed. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom...

4.5K
One of the applications of an RC circuit is the relaxation oscillator. The relaxation oscillator comprises a voltage source, a capacitor, a resistor, and a neon lamp. The lamp acts like an open circuit (infinite resistance) until the potential difference across the neon lamp reaches a specific voltage. At that voltage, the lamp acts like a short circuit (zero resistance), and the capacitor discharges through the neon lamp and produces light. Once the capacitor is fully discharged through the...
