Does waldenstrom's lymphoma (current igm 2300) cause memory impairment or erectile dysfunction?

Possibly: These are not classic symptoms of wm; however, this disease can, at extreme form cause neurological deficits, vascular compromise, and neuropathy. It is also important to note that these symptoms are relatively common complaints of adult male population. It's best to ask your hematologist about these symptoms since he/she would have an idea about the state of your disease & can speculate better.
