Was Marx Autistic?

I had this thought today and, seeing some reasons to think he may have been, decided to search the Web. I found someone else had posed the same question on Quora, and I wrote the following

I just had this thought a few minutes ago, and the more I think about it the more probable it seems.

I was identified as being autistic a little over a year ago (at age 57), and as a result I've learned a lot more about it since. One of the most significant things about autistics is that, being instrumental rather than social learners, we tend to think about objects more in terms of their objective properties and less in terms of how society defines them. The thought I had a few minutes ago was that maybe the reason many of Marx's ideas, like commodity fetishism, make more sense to me than to many other people is that, being autistic, it's easier for me to see through socially-consensual illusions such as the idea that value is an intrinsic property of an object rather than the social relation between people that it really is.

 
Once I had that thought, naturally the next thought was that maybe Marx himself was autistic, and that's why he was able to see through illusions like that. And then other thoughts: autism would certainly be consistent with Marx's intense focus on one subject — revolutionary philosophy and politics — over his entire life. It would also help explain why so many Marxist groups have failed to practice these in the same way Marx did — because, being composed mostly of neurotypical people, they adopted his doctrine in the fashion of taking on a marker of allegiance to a particular social group with a particular consensus reality, rather than perceiving things in a way that's independent of any social consensus, as Marx himself did. So , I think it's very likely Marx was autistic.
