HISTORY |
Around 1395 |
Fifteen year old Lydwina of Schieden fell while iceskating. Her
progressive disability is posited as the earliest written record of an
individual with multiple sclerosis. She was canonized as the Dutch patron
Saint of Ice Skaters by the Roman Catholic Church in 1890. |
1838 |
Medical drawings documented what is
recognized today as multiple sclerosis. |
1868 |
Jean-Martin Charcot,
professor of neurology at the University of Paris, wrote the first
comprehensive description of Multiple Sclerosis and the brain damage the
disease caused. He named the disease for the widespread scarring, may found
in a symmetrical pattern near the cerebrum's lateral ventricles. |
1878 |
French histologist Dr. Louis Ranvier
discovered and described myelin. As well as the gaps (nodes of Ranvier)
between the myelin sheaths of individual nerve cells. In 1919, spinal fluid
abnormalities were noted—their significance puzzled experts for decades. |
Early 1890s |
Dr. Sigmund Freud, psychologist,
treated his nanny for “Creeping Paralysis,” attributing the condition to
female hysteria, a diagnosis which explained female symptoms for years to
follow. As a result, multiple sclerosis received little or no extensive
research until recently. Male symptoms were attributed to multiple sclerosis. |
1925 |
Lord Edgar Douglas Adrian tested
electrical conductivity in the central nervous system of multiple sclerosis
patients. He proved that demyelinated nerves do not conduct electrical
impulses well. The same type of sensory impulse testing is still used today. |
1928 |
Researchers identified the
oligodendrocyte cell that makes myelin. |
1935 |
Dr. Thomas Rivers demonstrated that
nerve tissue, not viruses, produced an MS-like illness in animals.
Experimental allergic encephalomyelitis (EAE) reinforced present
auto-immunity theories, demonstrating the potential for the body to generate
an immunologic attack against itself. |
1938 |
Dr. V.B. Dolgopol described a case of
optic neuritis and attributed it to Devic’s syndrome, thought to be a
subclass of multiple sclerosis. |
1965 |
Multiple sclerosis researchers
discovered that blood cells react against a protein in nerve insulating
myelin. |
1992 |
The 16th edition of the Merck Manual
described multiple sclerosis as follows:
Plaques or islands of demyelination
along with destruction of both oligodendroglia and perivascular inflammation
are disseminated through the CNS, primarily in the white matter, with a
predilection for the lateral and posterior column (esp. in the cervical and
dorsal regions), the optic nerves and periventricular areas.
Tracts of the midbrain, pons and
cerebellum also are affected, cell bodies and axons usually are preserved,
especially in early lesions. Later, axons may be destroyed, usually in the
long tracts, and fibrous gliosis - this is what gives the tracts their
'sclerotic' appearance - Often both early and late lesions may be found
simultaneously. Chemical changes in lipid and protein constituents of myelin
have been demonstrated in and around the plaques.
The course is highly varied and
unpredictable and in most patients, remittent. At first, months or years of
remission may separate episodes, especially when the disease begins with
retrobulbar neuritis (optic neuritis), but usually the intervals of freedom
grow shorter, and eventually permanent, progressive disability occurs. Some
remissions have even lasted 25 years or more. However, some patients have
very frequent attacks and are rapidly incapacitated; in a few, particularly
when onset is in middle age, the disease course is progressively and
unremittingly downhill, and occasionally it is fatal within a year.
