question: I have CVID and get treatments every month by IVig. I am always getting sinus infections they just never seems to go away and broncitius every year along with some other medical issues such Central Apnea that is being treated and managed effectively. My question in the last six months my short term memory as gotten a lot worse. I forget just common words when speaking in conversation or can not remember what I did hour ago. It s something I have not brought to my Dr attention or my family I just don t want to feel like I am going nuts. I am 43 year old male.
