 Abstract: PRIMARY OBJECTIVE: Apathy is difficult to assess in clinical practice. Ambulatory actigraphy was used with the aim to measure locomotor activity during the daytime as a correlate of self-initiated action in brain-damaged patients with apathy. RESEARCH DESIGN: Twenty-four patients with acquired brain damage and high levels of apathy or low levels of apathy as well as 12 healthy controls were investigated using a parallel group design. METHODS AND PROCEDURES: Apathy was diagnosed after clinical observation and evaluated with the apathy evaluation scale. Locomotor activity was measured with a wrist-worn actigraph over 3 days. RESULTS: High apathy patients showed significantly reduced locomotor activity and more episodes of inactivity (naps) during the daytime. Self-rated apathy correlated with daytime activity, nap frequency and cognitive (executive) deficits. CONCLUSIONS: Ambulatory actigraphy is a promising method to evaluate self-initiated action in patients with apathy.
