Thank you for submitting your question.
I will answer your concerns to the best of my abilities, but please be informed that I am unable to offer a diagnosis based on your history and list of symptoms pertaining to your son.
I am extremely limited in not having the opportunity to perform a full neurologic examination on your son.
This is solely for educational purposes and should in no way be a substitute for a formal evaluation by a certified physician.
My dearest regards for what you are having to deal with as a concerned mother -- I know that the changes you have seen in your son are extremely frightening.
As an neurologist, I see memory loss and cognitive decline often -- but typically in elderly patients or patients who have had brain injury or trauma.
It is very unusual to see this pattern in teenagers and young adults.
Delayed onset of memory loss and odd behaviors (as you described above) in an otherwise healthy young person prompt two immediate thoughts that need to be ruled out.
1) Is this individual abusing drugs or alcohol?
2) Are there signs of depression?
I am in no way accusing your son of being engaged in illegal activity, but you as a mother will have to rule this out first and foremost.
Every teenager, regardless of his upbringing may be exposed to drugs and alcohol and undergo peer pressure to try these things -- in both public and private school settings.
You mentioned that your son was on Paxil -- is this for depression?
Paxil, or paroxetine is known to cause suicidality, worsening depression, mania, seizures, and electrolyte abnormalities as a side effect to its usage.
Please make sure that the Paxil is not causing any of these -- talk to the prescribing physician.
Alternatively, if he is indeed depressed perhaps the Paxil is not working to alleviate his depression.
Both extremes need to be formally evaluated by a physician.
Most importantly, talk to your son one-on-one.
If something is troubling him, talking to him will be both diagnostic and therapeutic.
If he shys from talking to you, have him see a counselor (one who is unattached and has undergone formal training to counsel youth.)
If both of these are completely ruled out, then other organic causes much be investigated.
There are not many neurologic diseases that present this way, but I suggest that you have him see a neurologist if the other two possiblities are ruled out and if his symptoms continue.
Best of luck,
Hope this helps,
I don't want to step on the learned toes of JKL, MD, but it is worth noting that in double blind studies, some cognitive impairments were reported by patients. Although the rate of occurrence was low (less than 2%) for memory associated side effects, there were reports of amnesia, stupor, etc. Personally, I think 2% is still high enough not to be dismissed out of hand, and the doctor's experience is noteworthy, I would still consider Paxil as a possible cause of any worsening cognitive impairments unless proved otherwise, especially if your son is taking *any* other psychoactive medications.
Just my 2 cents' worth.
My personal experience: I've been taking Paxil for years....occasionally, I have a lapse in common sense when performing fairly routine activities--example: for some reason, I decided to put my socks on before showering, and then set about trying to find a reasonable way to complete the shower without getting my socks wet--I laugh at it now, but at the moment, it seemed perfectly 'normal'....I guess the 'situations' are so few and far between that the overall benefit of the medication outways the 'odd moments' for me. And, no...I haven't been abusing drugs or alcohol during these 'episodes', either....
The doctor has to cover all bases....don't take offense....just love your boy as you obviously do, and double check with another doc regarding this issue....and DON'T stop his meds without talking to his or a new doctor, first....
