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]
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 ...
Focal injuries typically have symptoms that are related to the damaged area of the brain. [3] Stroke can produce focal damage that is associated with signs and symptoms that correspond to the part of the brain that was damaged. [1] For example, if a speech center of the brain such as Broca's area is damaged, problems with speech are common.
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]
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.
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.
Immunoreactive axonal profiles are observed as either granular (B, G, H) or more elongated, fusiform (F) swellings in the corpus callosum and the brain stem (H) at 24h post traumatic brain injury. Example of APP immunoreactive neurons (arrow heads) observed in the cortex underneath the impact site (E, G).
