Lead poisoning, central nervous system infections and cancer treatments are also potential risk factors.

A learning disorder is a permanent neurological condition that ranges from subtle to severe. It limits the brain's ability to store, process and produce information, and also affects the ability to read, speak, listen and write, according to Cleveland Clinic. As of 2015, an estimated 15 percent of children have learning disabilities.

There are no particular signs that directly prove a person has a learning disorder, although there are some common indicators, including trouble learning the alphabet and connecting letters to sounds, and repeating and pausing while reading out loud, explains MedicineNet. A limited vocabulary, misreading numbers, and trouble expressing ideas in writing are also indicators of a learning disorder.
