Narcolepsy01:07

Narcolepsy

179
Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.

Chemical Synapses01:26

Chemical Synapses

9.0K
Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

Parkinson's Disease: Overview

671
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Indirect-Acting Cholinergic Agonists: Pharmacological Actions

751
Indirect-acting cholinergic agonists, also known as anticholinesterases, exert their pharmacological effects by enhancing cholinergic transmission in various body parts, including the neuromuscular junction, autonomic cholinergic synapses, and the brain.
At the neuromuscular junction, these agents work by inhibiting the breakdown of acetylcholine, allowing it to remain bound to the receptor and bind to nearby receptors. This process leads to repetitive firing of the endplate, causing muscle...

Disorders of the Skeletal Muscle

1.0K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Direct-Acting Cholinergic Agonists: Therapeutic Uses

833
Direct-acting cholinergic agonists have many therapeutic uses in various medical fields. Choline esters, including acetylcholine, have limited clinical utility due to their non-selectivity and short duration of action. Still, acetylcholine and carbachol are applied topically during ophthalmologic surgery to induce miosis. Pilocarpine, a muscarinic and ganglionic stimulator, effectively treats open-angle glaucoma and alleviates xerostomia and dry mouth caused by radiotherapy or Sjögren...

    Area of Science:

    • Neurology
    • Movement Disorders
    • Genetics

    Background:

    • Chorea is a hyperkinetic movement disorder with diverse etiologies, including acquired and hereditary causes.
    • Accurate phenomenological definition is crucial for differential diagnosis, distinguishing chorea from other hyperkinetic movements.
    • Recent advances include genetic insights into Huntington disease (HD) and novel therapeutic targets.

    Purpose of the Study:

    • To provide a comprehensive overview of the diagnostic and therapeutic strategies for patients presenting with chorea.
    • To describe the phenomenology of chorea and differentiate it from similar hyperkinetic movements.
    • To review key clinical and historical features aiding etiological determination and discuss treatment options.

    Main Methods:

    • Review of clinical investigations and genome-wide association studies for Huntington disease.
    • Analysis of pharmacologic and nonpharmacologic treatment strategies for chorea.
    • Examination of diagnostic factors including age of onset, family history, and clinical features.

    Main Results:

    • Ongoing research targets mutant huntingtin protein for potential disease modification in HD.
    • New vesicular monoamine transporter-2 (VMAT2) inhibitors are being studied for chorea.
    • Genetic testing advancements increase awareness of HD mimics.

    Conclusions:

    • Chorea diagnosis requires precise phenomenological assessment and consideration of various etiologies.
    • While most treatments are symptomatic, identifying reversible or disease-modifying causes is essential.
    • Therapeutic approaches encompass both pharmacologic and nonpharmacologic interventions tailored to the underlying cause.
