This could be because of the gabapentin since short term memory loss is a side effect of gabapentin.
I have taken Gabapentin for the past 9 years. I take 3200 mgs per day (800mg X 4) My memory has gotten worse since the day I started this medication. It does help with pain, but comes at a price of which is memory loss.
Interesting. Have been taking 3600mg now for a month up from 3000mg on a move up over last 3 months. Done for depression. Memory problems been blamed on other things which indeed have caused problems before but now memory and being able to put two words together in a sentence while talking is near impossible. Scared! Anyone else on this much? For depression? How's one wean off? Withdraw? . Thanks
Get with your doctor before you start tapering off this drug. This too can have side effects. Memory loss and confusion is a known side effect of Gabapentin. I found a doc who agreed with the memory issue and walked me through the step down necessary to get off. Wishing you well.
Gabapentin affects my memory and my speech. Words come out wrong, even when I've thought them out correctly. It also makes my legs swell and I'm only on 300 - 600mg a day.
Are there studies proving it causes Alzheimer's, or is that coincidental?
Thinking about throwing mine away.
My father was prescribed Gabapentin today for sciatic nerve pain. He has dementia/Alzheimer's. He had been on Tramadol but it totally whacked him out so my mother took him off of it. Now, after reading these comments, I'm afraid of this new medication affecting his Alzheimer's. Anyone have any experience with that?
I've been on Gabapentin for just over a year. 300 mg in the evening for rls (restless leg syndrome). I am now weening off it. I've seen my Doctor several times over the year complaining of constantly feeling dizzy and off balance. The worse symptom is the brain fog!!! I no longer feel like I can have a normal conversation. Words are lost, I find myself embarrassed that I can't finish my sentences. When sending texts I can sit for 20 minutes trying to think of a certain word. For example today I was trying to text my husband about the (??? ), 20 minutes later I finally came up with storage bins. And that's still not the word I want. Dang the word, is still not coming to me. This goes on over and over all day long.
The other day I ran into someone I knew very well. I had to apologize, I couldn't remember who she was or her name. I just knew that I knew her.
I hope this isn't permanent!!!
I landed on this by accident and I felt I needed to add my 2 cents. I have 2 daughters ages 8 and 23. Both have Ehlers-Danlos and the older daughter is also being treated for Fibro. BOTH girls have taken gabepention and both have memory problems, they both have been off of it and back on. The 8 year old has so much trouble she cannot yet read, at age 3 she was developmentally on track but by age 5 was mildly delayed and now is listed as severely delayed in both cognitive and motor function. I asked repeatedly how she could have regressed but no one can answer this. My older daughter is taking Gralise which I was told is just an extended release of the gabepenton. her cognitive function and memory loss is continually getting worse. She was in advanced classes almost the entire time she was in school but can't remember her birthday now. I fear that there may be premanent damage for both, esp my younger daughter. But I will never have proof either way. Good luck to all of you
I realize some of the responses are older but I feel so strongly about this!
I saw my General Internist specialist last week and complained about all my cognitive issues. I told him I had NO short term memory left, I was spacing out and finding myself staring straight ahead but without any real thoughts going through my head. He laughed and said oh, yes that is the "high" with Gabapentin. I had no idea, but as I continued to describe my issues, I specifically ask him if my issues were coming from Gabapentin and he said no! He said it might cause a bit of brain fog but nothing else. I was describing hardly being able to function but he insisted it wasn't the drug and he wanted me to increase my dose... I was on 2700 mg per day already... I refused. I am not weaning myself to decrease the dose and have gone down to 1800 mg per day and now my pain level has gone up by quite a bit but I'd rather have that instead of feeling like my mind had totally gone!!!
When I could not remember my drive home from work, I started weaning myself off, abd went to a different doctor who agreed... This is a known side effect.
I'm so glad I found this post, I was going to go see a neurologist because I really feel as if I can't remember anything. Someone will be talking to me and I'll go to respond to their conversation and in a matter of moments I will forget what they were talking about.
So glad I found these answers! I too have been on Neurontin probably for at least a year. I would stop immediately but I'm afraid of withdrawal. Been on 1200mg a day. I have had two episodes of complete "blinking out" behind the wheel driving and the second time I was stopped by the police, then arrested (!) because I had drugs in the car which I absolutely don't remember how I got them! I do smoke, but this was crazy! I'm still awaiting my fate, but thankfully was released in my own recognizance. I have had to retain a lawyer and I'm scared. But the big point is I have no memory of driving on two occasions! I was on autopilot and God only knows how I didn't hit anything or anyone! I also think this is a very dangerous drug, and when this prescription is finished, I'm done with it! I am tempted to throw it away tonight after reading all the posts! As I've been weaning my memory's improving.
For months my friends thought I was high on something because they said I "was just staring into space ". I remember none of that. And now I must defend
myself. I really think Big Pharma is evil for putting this crap on the market! God only knows how many times I just "wasn't there". I am going to be 65 next month. Too old to be having to go through this. The pain be damned. I will not allow myself to be turned into a vegetable!
I know how you feel. Gabapentin definitely causes memory loss, slurred speech, and cognitive issues. I've been taking more Gabapentin than my doc prescribed me because of the high. I'm trying to taper myself off, and it hasn't been easy. I did go off of it a few months ago for a couple of weeks but ended up in the ER because I couldn't stop throwing up and had horrible muscle issues and could barely move. I need to get off of this stuff...
I have been using Gabapentin for about 5 years ago. My husband thinks I have lost my mind. Forgetting things is bad enough, but I tend to use the wrong word, when I clearly thought it correctly. In addition, I start in the middle of a thought instead of starting at the beginning. My articulation is growing increasingly hard to convey. I know it is from the medication because when my pain is somewhat controlled, I take less medication and tend to be sharper in my thought process. I have fibromyalgia and the pain is so severe and there are so many layers of symptoms that the medication helps control, that having a box of rocks for brains is better than having no quality of life.
I am 54 years old guy, been prescribed Gabapentin for over 2 years now. It was for me a tough pill to start, came down to having hallucinations for first few weeks but body seemed to acclimate to it. Short term memory is truthfully pretty much gone, long term seems pretty good though. My doctor increased my dosage and a bad stroke I had last year from 600 MG a day to 900 MG. I feel it too.
I'm one day shy of being 47. I broke my leg on 1/11/14. Because I'd left my job to care for my grandmother (Alzheimer's) I had no insurance a year later when I tell. I broke my leg quite severely, bit bottom line is that I too was prescribed Gabapentin, a.k.a. Nuerontin (please forgive my spelling). I was prescribed 1800 mlgrms per day, and started losing my short term memory quickly after. There are !literally 3 months I couldn't remember until a few hours ago when I looked at all the pictures of my leg, that I ultimately lost. I personally think Gabapentin is evil. I stopped taking it (slowly weaning myself) around April. I still have days when I can't remember the day before, or watching a movie the night before... I'm educated went from Medical Sociology to IT, and now I have to make lists and put post it notes everywhere. I think big pharma has some questions to answer.
So far in all my research (over a year) the best answer I've heard is we don't know if this is permanent, or if it will clear up on its own." This is not acceptable, and I would encourage anyone taking it to stop! When they can't tell you what the drug is doing to your mind, that should be a huge red flag.
I was taking Gabapentin about a year ago for siatica and stopped after an operation on my back (discectomy L4/L5) unfortunately the pain has returned due to a bulging disk (L3/L4) so I'm back on 300mg 3 times a day with several other tablets. I was in so much pain before my operation that everything was a blur, this time round I'm not quite as bad but I've realised how bad my short term memory is and I really don't like it.
I, too, take Gabapentin - not only did I have short term memory problems,
but I stumbled around walking like someone is drunk and had many
falls. I was on 600 mg a day, so I tapered off to 300 mg. My memory is a bit
better - but I have an autimmune disease called: Prurigo Nodularis and
need something to stop the insane itching and many sores all over my body.
Tell the doctor what you mother is going through and perhaps he'll have the
sense to try and put her on something less dangerous to her living.
God bless you both and Good Luck.

I recently started Gabapentin/Nerount.
My ability to focus has severely diminished. My short term memory has been dramatically reduced. It give new meaning to "one day at a time" since I can't remember yesterday.
Will this go away over time?
Please don't say ask my local physician. He's incompetent and dangerous. He has no idea regarding medication interactions or Ned side affects. He did however Google an article duri my visit.
What are your experiences with this medication?

My father was perfectly healthy with no family history of alzheimers. He developed restless leg syndrome and was given neurontin. Within weeks his short term memory started to go. The sad thing is he knew it and said he thought it might be the meds but the doc told him he was overreacting to normal slowing from the med. He continued to get worse. He quit the meds but continued a fast decline while on it and now 10 yrs later has very late stage alzheimers. We can't prove it was the meds, but we did have another neuro doc question why he was prescribed the neurontin. Many people have similar stories after being on neurontin. Some in their 20-30's too! I would say to anyone to never risk taking it. A doc just tried to prescribe it to me today for herniated disc pain and looked surprised when I turned it down and said why. These docs are not researching these side effects. My dad was 60 and really sharp. No strokes, no heart issues and no brain injuries.
These companies know this is a possible serious side effect but they and docs downplay it. To you docs who prescribe this, thanks for ruining people like my father's life.
OMG - So sorry about your dad. I have Fibro, could not take Lyrica, it made face, lips, and tongue swell. Have changed me to Neurontin. Don't feel it is helping at all, but take it b/c doctor wants me too. Hearing your story makes me thin I have a frank talk with my doctor!! Thanks for the input...
I am33 yr old female recently prescribed this med my short term memory is aweful now... I put something away and never remember where I put it... its terrible I specialize in Alzheimer's and feel I'm in the beginning stages BC this drug... I feel it may be a connection to Alzheimer's to your father..I will discontinue using this slowly but I hope my memory will come back... good luck with your father
I had terrible sciatic nerve pain too. It was to the point of barely able to walk more than 10 yards before having to stop. And getting in and out of my car was excrutiating. I finally got the surgery on my herniated disc and now am 100% better. The docs want you on the drugs at the so called pain management centers. Easy money for them. I recommend you get the surgery and get off the pills.
Just wanted a chance to give input concerning Neurontin. I have insomnia and was given Neurontin as a sleep aid. Took it nightly for 6-8 months. I was getting lost in parking lots. Forgetting online passwords. Forgetting my age and my children's b-days and what grade they were in. Neurontin was the only medication I was taking. The memory loss issues just slammed me after taking it for 6-8 months. I flushed the rest of pills down the toilet and never took them again. I have been off the medicine for about 2 years and though the memory loss is not as bad, I am still experiencing it. Always loosing my phone, keys, cannot recall if I have unpluged flat iron or locked a door. If only I could rewind the clock and never take that medicine. The word needs to get out. I also took this as a lesson to not faithfully follow your doctors opionion or advice. I feel a little ruined. Currently a mother and homemaker. One day I would like to be working again. And I now feel limited to what I can do in the workforce.
I am 88 years old and am manic depressive bipolar. I was on lithium for a number of years and my doctor switched me to Neurontin (gabapentin) I have no idea why he switched me to gabapentin, been on it since 1985. All I know about gabapentin (just 300mg) that I take at around 6pm every evening it acts for me like a sleeping pill... 6 to 8 hours sleep every night. Check your lithium level in your blood it might be you might need a small dosage of lithium.
I want to also say I have believed that taking 300mg of gabapentin daily has prevented me from ONLY one manic depressive bipolar incident within 32 years. Hope this is helpful. BTW, I am a Brit living in Florida, emigrated here 64 years ago and do I have a fantastic true story to tell.
I'm glad you spoke up. I'm sorry to hear about what happened to your dad.
However, I've been on neurontin for 12 solid years at top dose now and do not suffer any memory loss. Sometimes it's nearly impossible to tell if:
1) it's the drug itself only
2) it's the drug's peculiar effect on SOME but not all people
3) it's not the drug one is looking at but another (and with that one, don't know if it's #1 or #2)
4) it's not the drug at all, but a recessive gene that hasn't shown up in the family before that is known
5) comes from some other form of toxicity encountered in the person's lifetime.
So, the best we can do is share what we know as you did. Thank you. Should I develop any kinds of serious memory loss, neurontin will be the first thing I question.
Dear gram gram, I'm glad to come across with your question because it made me aware somehow as my mom also takes gabapentin due to post herpetic neuralgia (phn) which is the usual long term effect of post shingles. She has been taking this medication for about 6 months now. And so far I have not noticed her having any sign of memory loss. But this has aroused my concern because long term use may lead my mom to memory loss. Recently though, I have her taper the frequency of taking such medication as the major piercing nerve pain that bothered her for about 5 months is gone after taking Moringa oleifera. You may try giving your mom this amazing supplement it might help her with her phn and other health issues if any. Thanks.
I used to take Lyrica, which is like a sisterdrug to gabapentin, & was having horrible short term memory problems to the point I went to see a neurologist. I am no longer on Lyrica, & the short term memory problems have ceased. Hopefully this will be the case for your Mother. Once the shingles are gone, & she can get off the gabapentin, she should be ok... Mary
Get off the medication, from information I've read and seen myself memory loss is irreversible, there are other medications, dementia is a horrible terminal disease, only now is the side effects being realised
Oops, I might be commenting to the wrong writer. Anyway, memory loss is now thought to be reversible, as is Alzheimer's. There is a lot of infornation online now. Look up "Awakening From Alzheimer's" to see if you can find such information. If not, try looking up Dr. Sam Walters, Dr. Vincent Fortanasce, Dr. David Katz, and Dr. Dale Bredesen.
