Vocally disruptive behavior: A case report and literature review.

Vocally disruptive behavior (VDB) is a common and particularly difficult symptom to manage in dementia. VDB is usually considered collectively with agitation and aggression as a component of behavioral and psychological symptoms in dementia and is therefore poorly understood as an individual symptom. A review of the literature is described where VDB as a challenging behavior has been individually examined as a symptom. A case of VDB occurring in patient with dementia is described where the patient's repetitive vocalizations responded to treatment with pregabalin. This has not been previously reported in the literature. The prevalence of VDB, the factors associated with it and the current management guidelines for clinicians are outlined with a review of the drug treatment strategies for VDB. Pregabalin with its unique pharmacological profile and excellent tolerability should be considered as a possible treatment for VDB where drug treatment is indicated.
