trying43 has a good point it has been shown by experts that food supplements help and in fact are as good as Ritalin .an anti oxident VitC and BComplex has been effective ..
If u r not medicating her for adhd there are natural things u can do that may help. Flintstones vitamins with choline and kids fish oil. Both r sold at walmart. My son has adhd and so does my husband and these have helped them both. Good luck
Then in that case I do suggest that you have her evaluated at 7 years old her memory should be better , is it possible to get a 2nd opinion about whats going in, does she go to school is she happy there, has she any siblings ?
We have chosen not to medicate her, so she's not taking any meds.
So she has been diagnosed with ADHD is she on any meds for this and may I ask what they are ..some meds do have side effects and the dosage or the med may need changing ., the short term memory would be significant with some meds also the tiredness.
