Please hide my identity if you are posting it on Facebook. My son is 9 years old and is reading in class 3. He is having lack of concentration issue. He cannot learn his lessons by heart and if he is able to do so he forgot it in next few hours. However sometimes he learned all his assignment very quickly. We are very much worried due to his condition. I don't know either it is physiological issue or can be treated through medicine. Please help.
