Summary
Children with specific learning disorder (SLD) show altered auditory processing linked to cognitive deficits. These auditory processing issues and event-related potential (ERP) latencies correlate with neuropsychological test performance.
Area of Science:
- Neuroscience
- Developmental Psychology
- Audiology
Background:
- Specific Learning Disorder (SLD) impacts academic achievement.
- Auditory processing deficits are implicated in SLD.
- Event-related potentials (ERPs) offer insights into auditory pathway function.
Purpose of the Study:
- Investigate auditory sensory-perceptual aspects of SLD.
- Examine relationships between SLD, auditory processing, and ERPs.
- Explore short and long latencies of auditory event-related potentials (ERPs) in SLD.
Main Methods:
- Study included 34 children with SLD (7-14 years) and 15 controls.
- Comprehensive audiological and neuropsychological assessments were performed.
- Evaluated central auditory processing, brainstem evoked response audiometry, and long latency potentials (P3, N2).
Main Results:
- Auditory processing tests and P3/N2 latencies interacted with Wechsler Scale performance.
- Bender Visual Motor Gestalt Test errors correlated with lower parental education and auditory processing deficits.
- Longer P3/N2 latencies, especially in integration and rotation, predicted errors.
Conclusions:
- Children with altered auditory processing have a distinct cognitive profile, including reduced verbal and spatial reasoning.
- This profile is influenced by parental education level.
- Multimodal assessment is crucial for identifying specific needs in children with SLD.

02:18Intrinsically Disordered Proteins
19.2K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

The gastrointestinal tract is susceptible to various disorders. If the lower esophageal sphincter is damaged, stomach acid can flow back into the esophagus, causing irritation and inflammation of the lining. This condition is called gastroesophageal reflux disease (known as heartburn) and may cause chest pain and difficulty swallowing. In the stomach, prolonged use of nonsteroidal anti-inflammatory drugs like aspirin, chronic alcohol consumption, bacterial infections such as Helicobacter...

01:27Disorders of Erythrocytes
2.1K
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

01:27Disorders of Leukocytes
1.8K
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...

5.1K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...
