What type of disorder might a person experience if they have trouble constructing sentences?

A person who experiences difficulty in constructing sentences is likely exhibiting signs of a language disorder. Language disorders can affect various aspects of communication, including the ability to understand and produce language, both in terms of vocabulary and grammatical structure. When individuals struggle with sentence construction, it indicates a gap in their language development, which is characteristic of language disorders.

In contrast, auditory processing disorder primarily affects how the brain processes listening and understanding sounds, rather than the formulation of sentences. Obsessive-Compulsive Disorder is a mental health condition characterized by intrusive thoughts and repetitive behaviors, which does not directly relate to sentence construction. Speech-language pathology refers to the assessment and treatment of communication disorders, including language disorders, but it is not a disorder itself. Therefore, language disorder is the most accurate choice for someone having trouble with sentence construction.
