Presentation
Clinical presentation of ALS Initial presentation of ALS is asymmetric extremity weakness that affects the upper or lower limbs. Foot drop or lateral hand weakness and atrophy are the initial common presentations. [lecturio.com]
[…] disorders, sleep disorders, and others Major categories of systemic illness are explored for each presentation to guide you towards a likely cause. [books.google.com]
Pain is often a prominent feature and dysphagia is also sometimes present. [academic.sun.ac.za]
This does not imply that there are no antibodies present, but this terminology only became present because scientists were testing for the wrong antigen. [en.wikipedia.org]
Patients may also present with dysarthria, dysphagia, and less commonly with difficulty walking up stairs. Motor. The patient presents with weakness or fatigability that fluctuates throughout the day. [ahcmedia.com]

The condition is heralded by severe pain in the hip or shoulder with prominent weakness of the ilipsosas, thigh adductors, and quadriceps muscles; when the lumbosacral plexus is affected. [dartmouth.edu]
Respiratoric
- Respiratory Distress
Infants often present with hypotonia and respiratory distress. The diagnosis may be made by repetitive nerve stimulation studies. [academlib.com]
However, in the patient with acute respiratory distress, it is sometimes difficult to differentiate cholinergic from myasthenic crisis. [ahcmedia.com]
When respiratory distress is present, death can occur in the first year of life. There is delay of motor milestones during childhood. [nature.com]
Gastrointestinal
- Failure to Thrive
The course often is insidious and mistaken for failure to thrive. TREATMENT The most important aspect of treatment is supportive, with mechanical ventilation when necessary. [medtextfree.wordpress.com]

- Radiculopathy
Electrical activity at rest is abnormal; the particular pattern of firing may indicate denervation (for example, a nerve lesion, radiculopathy, or lower motor neuron degeneration), myotonia, or inflammatory myopathy. [medical-dictionary.thefreedictionary.com]
Radiculopathy Radiculopathy indicates damage to nerve root(s), and typically occurs as a component of several spinal diseases. In younger individuals this is usually due to intervertebral disc herniation. [dartmouth.edu]
- Waddling Gait
Lumbar lordosis, waddling gait, and Gower’s sign where the patients use their hands for support while standing up are also common. [lecturio.com]
The leg weakness frequently causes “foot drop” and a waddling gait. [britannica.com]
- Clumsiness
There may be weakness in thumb abduction and opposition (often with some clumsiness) and atrophy of the thenar muscles. [dartmouth.edu]
Workup
A search for SCLC, especially in men older than 40 years, is an essential part of the patient workup. Antibodies to the P-type or Q-type VGCC are also found in patients with paraneoplastic cerebellar degeneration in both the serum and the CSF. [what-when-how.com]
After complete workup, its frequency fell to 14%. [nature.com]
Treatment
The disorders should be further subclassified in all patients before deciding the exact treatment. Treatment for these autoimmune disorders consists of a combination of symptomatic and immunosuppressive drug treatment, and supportive therapy. [oxfordmedicine.com]
Fortunately, a wide range of symptomatic treatments, immunosuppressive drugs, or other immunomodulating therapies is available. [ncbi.nlm.nih.gov]
Hopefully over the next few years we will be able to move from anecdotal to evidence based treatment for this condition. Figure 2 shows a treatment algorithm for MG. Figure 2 Treatment algorithm for myasthenia gravis (MG). [jnnp.bmj.com]
Treatment There is no known cure and treatment is focused on rehabilitation and slowing of muscle weakness. [lecturio.com]

Each type has its own set of symptoms and prognosis. Carpal Tunnel Syndrome, ulnar neuropathies, and other focal nerve injuries and entrapments. [seton.net]
The long-term prognosis is poorer when a thymoma is present.[22] When death occurs from myasthenia gravis, usually it is because of respiratory failure with secondary cardiac dysfunction. [medtextfree.wordpress.com]

Possible etiologies include pregnancy, a compressing mass, aneurysm, trauma, tight clothing, obesity or diabetes. [hqmeded.com]
Infantile botulism is thought to be an occasional etiology for Sudden Infant Death Syndrome (SIDS). 29 Clinical Management. All suspected cases of botulism should be admitted to the ICU for observation and supportive care. [ahcmedia.com]
The treatment entails preventing other complications such as aspiration, and addressing the etiology more specifically. [nature.com]
Etiology Results from genetic mutation in the androgen receptor gene that is inherited in an x-linked recessive manner. Presentation This group of genetic disorders presents with muscle weakness and atrophy. [lecturio.com]
However, most of these conditions present in a rather stereotyped manner, and clarification of the precise etiology may require very elaborate procedures. [dartmouth.edu]
Epidemiology
The book also provides updated epidemiologic and statistical data throughout and includes a section on biostatistics in physical medicine and rehabilitation. [books.google.com]

MYASTHENIA GRAVIS Pathophysiology In anti-AChR antibody positive MG, autoantibodies target the acetylcholine (ACh) receptor (AChR) resulting in receptor blockade, down regulation, and complement mediated destruction, thus reducing the number of receptors [jnnp.bmj.com]
Underlying pathophysiology is related to a disorder of cell mediated immunity. Symptoms are prominent weakness of neck flexion and extension and of the shoulder and hip girdle. [academic.sun.ac.za]
Prevention
Some of these substances prevent the normal breakdown of acetylcholine after the nerve impulse has been transmitted to the muscle. Some neuromuscular junction disorders decrease the nerve's activity, causing weakness. [merckmanuals.com]
Builds a knowledge base of required skills for the necessary close observation and monitoring of the neuroscience patient to prevent complications and achieve the best outcomes. [books.google.de]
The toxin is taken up presynaptically in the cholinergic nerve endings by endocytosis and prevents the fusion of the synaptic vesicles with the nerve terminus. [ahcmedia.com]
Treatment The major concern is that inflammation in the muscle is followed by fibrosis and permanent muscle damage: an intensive effort must be made to prevent this happening. [academic.sun.ac.za]
Some of these things work by preventing the breakdown of acetylcholine after the transmission of the nerve impulse. [newhealthadvisor.com]
