Unusual types of MS have been described; these include Devic's disease, Balo concentric sclerosis, Schilder's diffuse sclerosis, and Marburg multiple sclerosis. There is debate on whether they are MS variants or different diseases. [31] Multiple sclerosis behaves differently in children, taking more time to reach the progressive stage. [5]
The injury in penetrating brain trauma is mostly focal (that is, it affects a specific area of tissue). [2] Studies with PET scanning and transcranial Doppler imaging have shown that changes in cerebral blood flow, such as hypoperfusion and vasospasm, can follow penetrating head injury. [5] These changes can last for two weeks. [5]
Main symptoms of multiple sclerosis Symptoms and findings in multiple sclerosis. Multiple sclerosis can cause a variety of symptoms varying significantly in severity and progression among individuals: changes in sensation (hypoesthesia), muscle weakness, abnormal muscle spasms, or difficulty moving; difficulties with coordination and balance; problems in speech or swallowing (), visual ...
Brain lesions associated with a clinically isolated syndrome may be indicative of several neurological diseases, like multiple sclerosis (MS) or neuromyelitis optica. In order for such a diagnosis , multiple sites in the central nervous system must present lesions, typically over multiple episodes, and for which no other diagnosis is likely.
Multiple sclerosis (MS) is an autoimmune disease resulting in damage to the insulating covers of nerve cells in the brain and spinal cord. [3] As a demyelinating disease , MS disrupts the nervous system's ability to transmit signals , resulting in a range of signs and symptoms , including physical, mental , and sometimes psychiatric problems.
Tumefactive multiple sclerosis is a condition in which the central nervous system of a person has multiple demyelinating lesions with atypical characteristics for those of standard multiple sclerosis (MS). It is called tumefactive as the lesions are "tumor-like" and they mimic tumors clinically, radiologically and sometimes pathologically.
A coup injury occurs under the site of impact with an object, and a contrecoup injury occurs on the side opposite the area that was hit. Brain injuries can result from a number of conditions, including: [22] Trauma; multiple traumatic injuries can lead to chronic traumatic encephalopathy.
Anti-MOG seropositive patients do not respond to approved MS medications. [16] In fact, it seems that MS patients with anti-MOG positivity could be considered a different disease in the near future. Comparative Effectiveness Research (CER) is an emerging field in Multiple Sclerosis treatment.
