Decreased concentration symptoms and conditions

I've been on Topomax for about 3-4 months now. I've had memory loss, slurred speech, decreased concentration (I have to re-read something several times to understand it) tingling in the hands and feet, depression, increased anger, loss of appetite, weight loss. I'm now at the point where I have a rash on my leg, severe nausea, and abnormal bleeding. I going to follow up with my neuro and PCP to see what's going on so we'll see. My migraines have decreased from 3-4 a week to maybe 1 a week, so it has been worth it so far so I can function for work and for my kids as a single mother. I've suffered from migraines for about 10 years and can't take the pain no more!!! If anyone has experienced the nausea, rashes or bleeding please reply.

my 3 1/2 year old son has had problems with focusing, hyperactivity at times, decreased concentration and inability to complete tasks. He has trouble falling asleep at night. Had him evaluated for this. Pediatrician suggested that it could be the zyrtec, since symptoms started about a year ago. MD stated that 2 other mother's started their child on Singular and then stopped the Zyrtec and saw an improvement in child's concentration. Will see
