Letter to the Editor: Persistent Headache in a Child with the Nephrotic Syndrome

To the Editor, Headache is a common problem in children. The effects of headache on the child’s academic performance, personality and interpersonal relationship depend on their etiology, frequency and intensity. The commonest cause of headache in an otherwise normal child is functional in origin. However, if it remains persistent, it may indicate a severe underlying disorder like brain tumor, sinus thrombosis etc. Thus, careful evaluation of children with recurrent, severe, progressive or unconventional headache is mandatory.
