Communication disorders often co-occur in individuals with mental health issues, with some people experiencing mental health problems related to pre-existing communication conditions (e.g. they feel depressed or anxious about their communication difficulties).
Communication and/or swallowing difficulties can also be part of a person's mental health disorder (e.g. disordered speech and language can be features of schizophrenia, and swallowing difficulties as part of dementia).
Swallowing disorders in mental health often occur as a side effect of medication or as a result of substance abuse or acquired brain injury.
