					Screaming and Wailing
in Dementia Patients (Part II)
Screaming is a behavioural problem that indicates great distress in patients which can also
be very disturbing and a considerable source of stress, not only for the other patients but
also for caregivers. After exploring its possible causes in Part I, this article addresses the
principles and examples of therapeutic approaches and interventions, with particular
emphasis on nonpharmacologic approaches.
