Can substance abuse like morphine addiction cause early...
Studies have shown that substance abusers do have issues with short term memory, fact recall, and mental agility. Abuse of pain pills over a long period of time can lead to memory loss. If you are addicted to pain pills, you should let your health care provider know so that can help you get treatment.
This is true because I have been on pain killers for nearly 30 years and I have severe memory loss.
You might also want to look into research done on different statins and memory loss. Talk to your health provider regarding this. It has had a huge impact on my own memory and the ability to understand things. With the help of my health provider I stopped taking Lovastatin and most of my memory has returned plus the ability to understand things. I also take pain medications and have for years.
