My brother does not have down syndrome. although he cannot read, write, or recognize different colors, he can memorize names/ faces.is there any cure?

Learning disorder: I must assume he has always had problems reading and writing. He has probably been in special education classes. I also assume he can learn but does so slowly with special help. Cure is not the issue. He needs to learn functional skills and good social skills and independence skills. Help find his place and find pride in himself. You express good concern - you are a good brother.

Unknown: Your question does not list enough information for any sort of comment on your brothers condition. Any child/teen/adult who cannot recognize and interpret symbols (letters) by the age of 8 likely has had permanent damage to the areas of the brain involved. The use of his facial recognition & auditory memory may help him get by, but the description suggests some permanent problems.

Diagnosis: The first thing is get him properly diagnosed. I would start with a pediatric neurologist or behavioral pediatrician. The evaluation should include chromosomal analysis with a micro array assessment. In addition a neuropsychological assessment should be done to determine what is are his strengths and weaknesses and help develop a program for teaching him.
