Summary
Myasthenia gravis, a neuromuscular disorder, can mimic stroke symptoms, leading to misdiagnosis. Early recognition and appropriate treatment are crucial for managing this condition, even in younger patients.
Area of Science:
- Neurology
- Immunology
Background:
- Myasthenia gravis (MG) is a prevalent neuromuscular disorder.
- Diagnosis can be challenging with comorbid illnesses or non-specific symptoms.
Observation:
- A middle-aged hypertensive male presented with symptoms mimicking acute ischemic stroke.
- Atypical MG was diagnosed due to persistent symptoms, AchR antibodies, and a fissured, atrophied tongue.
Findings:
- Initial misdiagnosis led to stroke management therapy.
- Definitive diagnosis and treatment with neostigmine, pyridostigmine, and prednisolone significantly improved symptoms.
Implications:
- Myasthenia gravis should be considered in the differential diagnosis of new-onset weakness, especially cranial.
- MG can present as a "stroke mimic" in various age groups, necessitating careful evaluation.

01:20Myasthenia Gravis: Overview and Treatment
2.4K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

01:15Myasthenia Gravis: Diagnostic Tests
1.6K
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.

1.4K
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...

01:26Chemical Synapses
10.5K
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...

Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...
