Disorders of the Nervous Tissue01:28

Disorders of the Nervous Tissue

3.0K
Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.

Drugs Affecting Neurotransmitter Synthesis01:29

Drugs Affecting Neurotransmitter Synthesis

2.4K
Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase,...

Cognitive Development During Adolescence01:18

Cognitive Development During Adolescence

795
During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...

Role of Neurotransmitters in Memory01:23

Role of Neurotransmitters in Memory

2.8K
Neurotransmitters are integral to the brain's communication system, enabling neurons to transmit signals across synapses. This chemical exchange underpins various cognitive functions, including memory processes. The role of neurotransmitters in memory is multifaceted, influencing the encoding, consolidation, and retrieval of memories through their action on different neural circuits.

Glutamate, the brain's main excitatory neurotransmitter, is...

Drugs Affecting Neurotransmitter Release or Uptake01:21

Drugs Affecting Neurotransmitter Release or Uptake

1.8K
Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

1.3K
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....

Summary

Vitamin B12 deficiency, though rare in children, can cause neurological issues. Early diagnosis and treatment are crucial to prevent lasting damage, even in cases of pernicious anemia.

Area of Science:

  • Pediatric Neurology
  • Hematology

Background:

  • Vitamin B12 deficiency is uncommon in children, with pernicious anemia being an even rarer cause.
  • Clinical presentation in children is often subtle and can lead to delayed diagnosis.

Observation:

  • A previously healthy adolescent presented with neurological symptoms including emotional lability, altered mental status, hyperreflexia, and ataxia.
  • The patient was diagnosed with megaloblastic anemia and subacute combined degeneration.

Findings:

  • The patient's condition was secondary to vitamin B12 deficiency caused by pernicious anemia.
  • This case highlights the importance of considering B12 deficiency in pediatric neurological presentations.

Implications:

  • Early recognition and treatment of vitamin B12 deficiency in children are vital.
  • Prompt intervention can prevent irreversible neurological sequelae in pediatric patients.
