Summary
Noninvasive brain stimulation (NIBS) shows promise for alleviating neglect post-stroke, but its effects on other cognitive domains require further investigation. Standardized protocols and outcome measures are needed for clearer efficacy evaluation.
Area of Science:
- Neuroscience
- Rehabilitation Medicine
Background:
- Cognitive impairment after stroke significantly impacts quality of life and independence.
- Noninvasive brain stimulation (NIBS) is established for language recovery but its role in other cognitive domains is less understood.
Purpose of the Study:
- To systematically review the effects of different NIBS techniques on domain-specific cognitive recovery after stroke.
Main Methods:
- A systematic literature search was conducted across PubMed, EMBASE, and PsycINFO up to January 2018.
- Included studies comprised randomized controlled trials, crossover designs, case studies, and mixed-design studies.
Main Results:
- Forty articles were included, with most focusing on neglect (n=25).
- A majority of studies indicated treatment effects in at least one cognitive domain at some point post-stroke.
- Significant variability existed in study parameters like time post-stroke, session number, and stimulation protocols.
Conclusions:
- NIBS appears effective in alleviating neglect post-stroke, though evidence for other cognitive domains is preliminary.
- Standardized outcome measures and treatment protocols are crucial for robust evaluation and comparison of NIBS efficacy in stroke recovery.

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...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

14.7K
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

01:17Systematic Sampling Method
12.7K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.

6.9K
The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep brain...
