Mixed receptive-expressive language disorder

Mixed receptive-expressive language disorder (DSM-IV 315.32) is a communication disorder in which both the receptive and expressive areas of communication may be affected in any degree, from mild to severe.
If someone is being assessed on the Wechsler Adult Intelligence Scale, for instance, this may show up in relatively low scores for Information, Vocabulary and Comprehension (perhaps below the 25th percentile). If the person has difficulty with spatial concepts, such as 'over', 'under', 'here' and 'there', she will not do as well in Arithmetic, and have difficulty understanding word problems and instructions, or using these words herself.
She may also have a more general problem with words or sentences, both understanding and speaking them.
If someone is suspected to have mixed receptive-expressive language disorder, then he or she can go to a speech therapist or pathologist, and receive treatment. Most treatments are short term, and rely on accommodations made in the person's environment, so as to be minimally interfering with work and school functioning.
