Is there any relationship between atherosclerosis and multiple sclerosis?

Yes, unrelated. Atherosclerosis is a progressive disease also known as hardening of the arteries - fat, cholesterol and other substances build up in the arteries forming plaque and reducing the area in which blood can flow. Multiple sclerosis is an autoimmune disease that affects the brain/central nervous system and impedes function in attacks that tend to increase in severity and duration.
No relationship. Atherosclerosis is due to aging, hypertension, high blood lipids, diabetes, hyperhomocysteinemia, etc., and involves progressive arterial narrowing. Ms occurs in younger folks, and is an autoimmune process. Of interest, the historical low fat swank diet seemed helpful in many, and this is a good diet for heart disease prevention. In short, no pathogenic association with vascular disease.

Is there any connection between atherosclerosis and multiple sclerosis at all?

No. Sclerosis means hardening. In atherosclerosis it refers to plaques on the inside of the arteries that block the flow of blood. In ms it refers to plaques in the brain.
NONE. No direct or indirect connection between hardening of arteries and multiple sclerosis.

Mood swings and multiple sclerosis. Any relationship?

Yes. Multiple sclerosis has many psychiatric manifestations, both to the emotional effects of having a chronic and incurable (albeit treatable) disease and to direct effects of the plaque on the emotional pathways of the brain. When you see your neurologist about ms, don't forget to mention emotional issues as well as more classically neurological ones- they may be able to help!
Yes. Depression is common in people with ms. I say to people, "is it the disease or is it the disease that plays a part? " what I mean by this, is having a chronic disease can certainly be involved. But, there are changes/lesions in the brain that could also play a part.
Can occur. Since MS affects multiple areas of brain, and the fact that up to 65% of pts may experience some cognitive difficulties, it would not be surprising to have emotional symptoms. Might see euphoria, depression, emotional lability called Pseudobulbar Affect Disorder. All of this should be assessed and treated. A new drug called Nuedexta may be indicated.

Is there a relationship between multiple sclerosis and dysarthria?

Yes. Ms can affect virtually area of the central nervous system, and dysarthria is most commonly notice with lesions in the lower medulla oblongata close to cranial nerves nine and ten. Occasionally higher lesions can cause dysarthria, and these are associated with more vocal straining. The key lesson, treat acute changes immediately and use the newer more potent agents to prevent relapses.
Cause-effect. Damage to the brain from any cause (stroke, trauma, infection, ms, etc) may result in dysarthria. If the part of the brain that is responsible for articulation is damaged, whatever the cause, slurred speech (dysarthria) can result. This is just basic neuro-anatomy.

Multiple sclerosis TMJ. Any relationship? I read some article about similar symptomps

No. Multiple sclerosis is strictly a disease of the brain and spinal chord and doesn't affect the joints. If you have one autoimmune disorder like MS, you can however be prone to another like rheumatoid that can cause arthritis, including arthritis of the TM joint.

Told I have optic neuritis for the first time. What is it and relationship to having multiple sclerosis?

See Neuro-ophthalmol. In caucasian populations in temperate latitudes MS will be the most common form of optic neuritis. In non-caucasians, this will not be so. It is a subacute visual loss with an inflammatory cause. This could be demyelinating (ms), infectious, post viral, or other such as sarcoidosis or vasculitis. Results of your MRI are key in predicting your chance of a second event or diagnosis of ms. See a neuro-opht.
Optic neuritis. Optic neuritis is an inflammatory condition of the optic nerve. One of the many causes of optic neuritis is inflammation caused by multiple sclerosis in which the immune system attacks the myelin sheath around the optic nerve which leads to a decrease in vision.
Description. Optic neuritis involves inflammation of the optic nerve which causes, loss of vision, dull color perception, and pain on movement of the eye. This maybe an initial presentation of MS, and in some studies 50-60% of pts go onto MS. But sometimes, just an isolated event which is treated and never goes onwards. An MRI of brain will assist in predicting next phases.
