The normal ageing process produces sensory losses such as visual impairment. This is of particular concern for those with Alzheimer’s or other dementias as they may not be able to understand why and therefore be unable to compensate for it. Good design helps them cope with this loss.
The elderly gradually lose the ability to discriminate between colours and this is exaggerated with dementia, so the use of contrasting colours within design is vital. Contrast seating with carpets, bedspreads and flooring, door handles from doors, light switches from walls, etc. Pale colours together (or a mass of dark shades) are difficult to discern by the visually impaired.
Look to add texture and semi-plains to create interest and, most importantly, select fabrics for seating which clearly contrast in colour and shade with carpet colours to ensure that seating is clearly visible.
