<s>[INST] I have in the last two weeks found it hard to remember simple words when I am talking. This is starting to bother me. I am 56, so can it be aging or drug related? I have recently started to take diclofenac for severe arthritis in my lower spine . I am also on cymbalta and lithium, as well as a stomach pill because of the diclofenac. thanks [/INST] Hi.it may be early onset dementia or depressive symptoms, although it will be counted upon how you feel these days.sad or normal. I don't know why you are taking lithium.may you have bipolar disorder, or it may an add-on for duloxetine to treat resistant depression.so please consult your psychiatrist and a detailed mental status examination should be conducted.also a brain-imaging should be done.diclofenac is nothing to do with forgetting.have a good health after a proper consultation. </s>
