Excessive TV watching in patients with frontotemporal dementia.

The "environmental dependency syndrome" refers to a loss of personal autonomy such that a person's environment almost entirely controls their actions. The goal of this study is to learn if patients with frontotemporal degeneration (FTD) exhibit prolonged TV watching, a behavior which may be a symptom of environmental dependency. We recruited 40 patients with FTD and 48 patients with Alzheimer's disease (AD), and asked these participants' caregivers about TV watching behaviors including total viewing time and channel/show preference, along with other behaviors indicative of environmental dependency.
