Study Notes
Key Facts about Multiple Sclerosis (MS) Diagnosis and Symptoms
- Transverse myelitis is an inflammatory disorder of the white matter of the spinal cord that commonly affects the cervical dorsal spine, causing weakness, sensory loss, gait impairment, and urinary incontinence.
- In patients with MS, transverse myelitis is typically incomplete and presents as a partial myelopathy rather than dense paraplegia or quadriplegia. Progression occurs over days to weeks.
- Internuclear ophthalmoplegia (INO) is a well-known pattern of diplopia in MS, characterized by impaired adduction of the ipsilateral eye and jerky nystagmus on abduction of the contralateral eye.
- Demyelination in the cerebellar white matter and its brainstem connections can lead to incoordination, ataxia, and intention tremor in MS patients.
- Early diagnosis of MS is valuable as it allows for the initiation of disease-modifying therapy at the beginning of the disease process, potentially preventing severe disability.
- There is no single symptom, sign, imaging finding, or laboratory test that is 100% reliable for the diagnosis of MS. It is a clinical diagnosis supported by findings obtained from MRI, CSF analysis, and evoked potentials.
- The central criterion for diagnosing MS is the presence of disseminated CNS lesions in both white and grey matter, which are seen on MRI.
- Prior symptoms typical for MS, such as visual loss, weakness, numbness, double vision, vertigo, and clumsiness, support the diagnosis when they last longer than 24 hours.
- Physical examination findings that suggest prior optic neuritis or demyelination of the spinal cord, such as red desaturation, optic atrophy, relative afferent pupillary defects, hyperreflexia, and upgoing toes, support the diagnosis of MS.
- MRI of the brain and spinal cord is the most useful diagnostic tool for suspected MS patients, with T2 hyperintense lesions in the periventricular white matter, corpus callosum, centrum semiovale, and middle cerebellar peduncle being characteristic findings.
- Dawson fingers, which are T2 hyperintense lesions perpendicular to the corpus callosum, are particularly characteristic of MS.
- Lumbar puncture and CSF analysis can provide additional supportive evidence for the diagnosis of MS, including the presence of oligoclonal bands and increased intrathecal synthesis of IgG.
