Insights

Children with attention-deficit/hyperactivity disorder (ADHD) exhibit abnormal alpha brainwave patterns when processing human eye gaze. This neurophysiological difference in the left hemisphere may serve as a marker for attention deficits in ADHD.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Child Psychiatry

Background:

  • Attention-deficit/hyperactivity disorder (ADHD) is marked by attention regulation difficulties.
  • Children with ADHD often struggle with social cue processing, like eye gaze.
  • Previous research suggests altered orienting responses to human eye gaze in ADHD.

Purpose of the Study:

  • To investigate the neurophysiological underpinnings of attention deficits related to social eye gaze in children with ADHD.
  • To explore the specific relationship between alpha wave modulations and ADHD symptoms during a visuospatial attention task.

Main Methods:

  • Electroencephalography (EEG) was used to record brain activity in typically developing (TD) children and children with ADHD (ages 8-13).
  • Participants performed a cued visuospatial covert attention task using human eye cues.
  • Analysis focused on alpha band modulations, particularly in response to left/right gaze cues.

Main Results:

  • Typically developing children demonstrated significant alpha lateralization in response to eye gaze.
  • Children with ADHD exhibited an inverse pattern of alpha modulation in the left parieto-occipital region.
  • Abnormal left-hemisphere alpha modulation correlated with inattentive symptom severity and reduced behavioral accuracy in ADHD.

Conclusions:

  • Dysfunctional alpha modulation in the left hemisphere in response to social cues is identified in children with ADHD.
  • These abnormal alpha modulations may represent a potential neurophysiological marker for attention deficits in ADHD.
  • The findings highlight the role of specific neural mechanisms in social attention impairments in ADHD.

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Respiratory System Abnormal Finding I: Inspection and Percussion

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.

Cardiovascular System Abnormal Findings II: Auscultation

Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

Prediction Intervals01:03

Prediction Intervals

The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
