Patients with any dementia are much more sensitive to loud noises, be it music, loudspeakers, crowds, or whatever. Because their brains cannot cope with the noise, they become more agitated—resisting care, restless, not sleeping, more uncomfortable.
A review of dementia-related associations/agencies, finds they recommend: keep noise down!! For example, the Alzheimer’s Association states that noise can trigger agitation and delirium. The Lewey Body Dementia Association feels loud television noises may increase a patient’s paranoia—believing people in the next room are yelling at him, and creating more fear, anxiety, and difficult to manage behaviors.
