Is there a cure?

There is no cure for GRIN2B syndrome, but therapy, nutritional support and medications can help manage symptoms, prevent complications and improve quality of life.

The information in this section was gathered by parents who completed a survey asking them what types of treatments their children had received.  Not every child with a GRIN2B variant will need/benefit from each of the therapies/treatments below.  Please consult with your child’s medical team to determine your child’s needs. If you would like to know specific information on how some of our children are responding to any of these treatments, please contact us at or ask a question in the private Facebook group.

Please consult with your child’s doctor if you are interested in starting any of the below-mentioned medications for your child.  Remember, we are not medical professionals.  We are parents sharing information on what has worked for our children.

The following two medicines are commonly discussed in our Facebook group:

  • Memantine – Memantine is an antagonist of NMDA receptors. This drug is normally used in Alzheimer’s patients, but is being re-purposed for use on GRIN2B patients. Memantine should be used with extreme caution in CHILDREN; safety and effectiveness in children have not been confirmed. For information about possible upcoming clinical trials, head over to News.
