Is there any connection between Lupus & A.L.S., even if only symptomatically?

Does anyone happen to know if there is any connection between Lupus & A.L.S. (Lou Gehrig's Disease)?  My father passed away from A.L.S.  I'm diagnosed with Lupus.  ...Wondered if there is some kind of link genetically?  For that matter, have often wondered and can't seem to get a good answer, is there any reason to believe that Lupus is often mistaken for A.L.S., at least in the early stages?

Thanks.  AGH

  Hello, i am sorry for the loss of your father and for the fears and concerns that you are having.

   I do not think that Lupus is mistaken for ALS because of the different symptoms they present with.  By Mayo Clinic staff

No two cases of lupus are exactly alike. Signs and symptoms may come on suddenly or develop slowly, may be mild or severe, and may be temporary or permanent. Most people with lupus have mild disease characterized by episodes — called flares — when signs and symptoms get worse for a while, then improve or even disappear completely for a time.


    With ALS, sx's  become progessively worse over time and do not have periods of remissions.   "Lou Gehrig's Disease," is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body.

    When there is  No muscle nourishment because of portions of the nerve cells that signal and control the muscles are located degenerates it leads to scarring or hardening ("sclerosis") in the region.
. When a muscle has no nourishment, it "atrophies" or wastes away.

    I hope this has helped and made sense to you. I wish you the best :)
