Snoezelen or controlled multisensory environment (MSE) is a therapy for people with autism and other developmental disabilities, dementia or brain injury. It consists of placing the person in a soothing and stimulating environment, called the "Snoezelen room", a form of sensory room. These rooms are specially designed to deliver stimuli to various senses, using lighting effects, color, sounds, music, scents, etc. The combination of different materials on a wall may be explored using tactile senses, and the floor may be adjusted to stimulate the sense of balance. The person is usually accompanied by an aide or therapist.
Developed in the Netherlands in the 1970s, Snoezelen rooms (snoezelroom) have been established in institutions all over the world and are especially common in Germany, where more than 1,200 exist.[citation needed]
There is no evidence that Snoezelen is effective for the treatment of dementia.[1]
