I am 20 years old and am worried that my 4 anxiety filled years will increase my chance of getting Dementia/Alzheimers later in life as I have read about several studies which have shown a link between anxiety and Dementia. I have convinced myself that I will most definitely get Alzheimers in the future and have been obsessed with these thoughts for around a month.I have had some problems with memory in the past due to anxiety and this has caused me to believe I have damaged my brain permanently to the point of no return and I am bound to get Alzheimers.I have googled (i know its bad) and found that anxiety can cause alzheimers in people if they experience anxiety or depression when older and a neuroticism may also cause this which has dug my hole even further. Any help, advice or information would be greatly appreciated.
