Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

6.8K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

665
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....

Functions of Thyroid Hormones01:18

Functions of Thyroid Hormones

4.7K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

The Thyroid Gland01:23

The Thyroid Gland

6.4K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Negative and Cognitive Symptoms of Schizophrenia01:30

Negative and Cognitive Symptoms of Schizophrenia

347
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Therapeutic Drug Monitoring: Affecting Factors01:29

Therapeutic Drug Monitoring: Affecting Factors

138
Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.

Summary

Hyperthyroidism patients show improved anxiety, depression, and executive control after treatment, but attention deficits in the alerting network persist. This highlights the long-term impact of thyroid dysfunction on cognitive function.

Area of Science:

  • Neuroscience
  • Endocrinology
  • Psychiatry

Background:

  • Hyperthyroidism is associated with affective symptoms and attention impairments.
  • Previous research indicated attention network deficits in hyperthyroid patients.
  • The persistence of these impairments post-treatment remained unclear.

Purpose of the Study:

  • To investigate the long-term effects of hyperthyroidism treatment on affective symptoms and attention networks.
  • To determine if attention deficits persist after achieving euthyroidism.

Main Methods:

  • Recruited 20 healthy controls and 25 hyperthyroid patients.
  • Administered the Attention Network Test (ANT) to assess alertness, orientation, and executive control.
  • Evaluated affective symptoms and attention networks before and after 1 year of anti-thyroid medication.

Main Results:

  • Hyperthyroid patients exhibited higher anxiety and depression scores and impairments in alerting and executive control networks.
  • Treatment improved affective symptoms and executive control network function.
  • Deficits in the alerting network persisted even after achieving euthyroidism.

Conclusions:

  • Hyperthyroidism is linked to affective symptoms and attention network impairments.
  • Thyroid function normalization improves affective symptoms and executive control.
  • Alerting network deficits may persist post-treatment, suggesting lasting cognitive effects.
