BOOK REVIEW
Appleton R, Peters B. Common Neurological Problems in General Pediatrics.
London, United Kingdom: Martin Dunitz; 2003
The world of child neurology has become increasingly complex with rare,
bizarre syndromes, complex investigations and brain imaging, new genetics, and
exotic medications. The generalist pediatrician may feel in danger of obsolescence,
yet neurologic problems of varying severity are common in children. This little
book comes to the rescue. The authors are well-known child neurologists (one
Dutch, one British), but the book is aimed at general pediatricians. There are only
four chapters but they cover by far the most frequent problems in child neurolo-
gy—“Fits, Faints, and Funny Turns,” “The Floppy Infant,” “Headache in Chil-
dren,” and “The Child With Learning Difficulties.” The differential diagnosis for
seizures is elegantly and simply discussed. The authors endorse an approach of
waiting for additional attacks if the diagnosis is unclear. The headache discussion
emphasizes when to be concerned about serious intracranial pathology and how to
treat migraine (the most common pediatric headache). Floppy infants may have all
kinds of disorders ranging from serious muscle disease to chromosomal abnor-
malities with brain malformations. An algorithm is proposed that leads the clini-
cian fairly easily through this complex symptom. “Learning disability” in Europe
means “mental handicap/retardation” in North America; here is a chapter about
how to investigate serious cognitive problems. These four key subjects are admi-
rably discussed by two master clinicians. Buy it; you will like it.
