I am a 71-y-o white female with IBS. A Houston neurogastroenterologist put me on Xanax (+ other meds) 10+ years ago and I was later put on gabapentin by a Houston neurologist for an undiagnosed (not epilepsy or Parkinson s) heavy, significant intermittent tremor sometimes associated with stress. Could either of these long-term drugs cause memory loss re. vocabulary (words & names)? It s is very frustrating and seems slowly increasing.
Long term use of Xanax, alprazolam causes decreased concentration, decreased memory but not severe memory loss. Gabapentin may cause excess sedation, decreased concentration. But no severe memory loss by either Chat Doctor.  At 70 yr age most common cause of memory loss is Alzheimer disease. It is slowly progressive degenerative disease cause memory loss in old age
