Individuals with Primary Immunodeficiency Disease (PID) have increased risk for infection, autoimmune conditions, and inflammatory disorders. Cognitive impairment, also referred to as brain fog, has been recognized in other medical conditions and as a side-effect of treatments; however, it has not been previously reported in individuals with PID. The phenomenon of brain fog is recognized in other autoimmune or inflammatory conditions, including lupus, multiple sclerosis, chronic fatigue syndrome, and has resulted from chemotherapy treatment for cancer. This research investigates the self-reported memory function of individuals with a diagnosis of PID. Respondents completed a survey which used reliable and valid questionnaires: Memory Functioning Questionnaire, Beck’s Depression Inventory II, and Beck’s Anxiety Inventory. Of the 292 completed surveys, 133 did not report any comorbid neurological diagnosis or incident of concussion (both of which could influence perceived memory function). When compared to normative scores, the respondents in this study were found to have significantly greater perceived memory impairment. The respondents had a significant higher score for anxiety and depression as compared to non-anxious and non-depressed normative values. This study finds that individuals with a diagnosis of PID have a greater degree of perceived memory impairment, or brain fog, in addition to greater levels of anxiety and depression. Individuals with a diagnosis of PID would benefit from prospective surveillance through a comprehensive neuropsychological assessment to track cognitive status and implement corrective measures, should any decline be identified.
