Do diffused large b cell lymphoma patients show symptoms of mental abnormalities?

Maybe: In general we don't think of diffuse large b cell lymphoma (dlbcl) effecting brain function. However, many patients tell us of symptoms of a "fog" like feeling either before treatment (disease-related?) or after ("chemobrain"). Reasons are likely multifactorial and can include stress, financial concerns, depression, and disease biology. This is being actively studied by a variety of groups.

Maybe: I am not an oncologist, but any chronic disease can lead to symptoms of depression and anxiety. If there are cancer lesions in the brain, this could also create issues. You should discuss this with your primary care doctor or your oncologist.
