<s>[INST] My husband is a long term chronic Alcoholic 30 yrs. and I feel very strong that he has some sort of dementia and can not get any of his Dr.s to be on the same page.I try to give the Dr. straight facts to his behaviors along with the non logical thinking but he denies all when we get to the hosp or Dr. Office. He is also suffering from severe panic disorder, He is in and out of the Hosp. with the same complaints. I know this panic disorder makes you ill physicaly as well. Would a Pet scan show dementia in the brain? [/INST] Hello, Alcohol dementia and Panic disorders may be due to Excessive Chat Doctor.  The process of acquiring knowledge and understanding through thought, experience, and the senses (cognitive skills), memory and learning are affected because of this excessive alcohol. Positron emission tomography (PET) is useful in certain diffuse brain diseases such as those causing various types of dementias including Alcohol dementiaWith best wishes </s>
