[|Human|] Hi, I suffered 2 bumps to the head earlier this year on separate occasions, both large lumps but never felt the need to get medical help. Keep suffering from memory loss and noticed i have being wrighting letters back to front. I forget that i shown something to someone or askthen thesame question half hour later. I have recently been suffering from headaches although i so suffer from migrane and recently noticed the flashing lights but nver seem to get the full blown migrane now. D o i need to seek  nmedical advise . I am 45 yrs and quite fit and healthy, drink socially once a week if that. thanks
[|AI|]  I think anyone who is concerned about their health should seek medical advice. Head lumps themselves do not cause memory problems, but concussions can if the injury was severe enough.  Only a qualified professional will be able to tell you whether your injuries were severe enough. The other causes range from medication effects and sleep problems to Alzheimer's disease and only a qualified doctor will be able to help with that as well. As with all problems there are usually many possible causes
