Other hallucinations may be visual, tactile, or less common are smelling odors no one else does.
Difficulties concentrating and focusing attention are common.
The person may be unable to sort out what is relevant and what isn't to a situation. Their thoughts may not flow in logical order and they may jump from topic to topic in a confusing manner.
