Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.

Visual Agnosia

Visual Agnosia

Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round end"...

Summary

This summary is machine-generated.

Unilateral spatial neglect, a deficit following brain injury, stems from disrupted attention networks, not just localized damage. This impacts spatial and non-spatial functions, particularly in the right hemisphere.

Background:

Unilateral spatial neglect is a common neurological syndrome after brain injury, primarily affecting the right hemisphere.
It presents with both spatial deficits (saliency coding, attention, memory) and non-spatial deficits (reorienting, detection, vigilance).

Purpose of the Study:

To propose that unilateral spatial neglect is better explained by the dysfunction of distributed attention networks rather than structural damage to specific brain regions.
To elucidate the roles of ventral and dorsal frontoparietal attention networks in neglect.

Main Methods:

The study reviews existing literature and proposes a network-based model of unilateral spatial neglect.
It analyzes the impact of ventral cortical lesions on non-spatial functions and their interaction with dorsal attention networks.

Main Results:

Ventral lesions in the right hemisphere directly impair non-spatial functions mediated by the ventral frontoparietal attention network.
Damage to ventral cortex also causes abnormalities in the dorsal frontoparietal network, crucial for spatial attention.
The right hemisphere dominance of neglect is linked to the anatomy and laterality of these interacting ventral and dorsal networks.

Conclusions:

Unilateral spatial neglect arises from the dysfunction of distributed attention networks, particularly frontoparietal networks.
Both spatial and non-spatial deficits in neglect are consequences of these network disruptions.
Understanding these network interactions is key to explaining the lateralization and characteristics of neglect.
