Your starting point is the ECAT Manual—a user's guide, technical manual, and educational resource all in one easy-to-use book!
The Manual details how limitations associated with dementia can impact communication, describes step-by-step how to complete the assessments, and includes appropriate interventions and modifications in handy tables cross-referenced to the assessments.
These interventions and modifications offer specific strategies for implementing environmental changes that tackle the communication difficulties the Toolkit allows you to pinpoint.
The Manual has other bonuses, too—like the final section with everything you need to know about lighting (methods, types, fixtures, bulbs, suppliers, and more).
