<s>[INST] I was diagnosed with a Cebral Brain Aneurysm in May 2012. Anerysm removed in Feb. 2013. Long story short, I am a recovering alcoholic. In 2011 my choices became quite erratic, sold my home moved, 3 mths later moved back and returned to my job. I was working in Health Care. I couldn t settle my self or make any choices or committ to them. In March of 2012 I began drinking alcohol & smoking pot after 7 years of sobriety. In May of 2012 I had a stroke and of course ended up at the hospital where I had a CT scan & aneurysm was found. Could the Cebral Aneurysm caused my erratic behavior? kind regards [/INST] Hello, Thanks for the query, I understand your problem Aneurysms may result from congenital defects, preexisting conditions such as high blood pressure and atherosclerosis (the buildup of fatty deposits in the arteries), or head trauma. Alcoholism per se may not be directly responsible for cerebral aneurysm formation.
