Specialists are due to arrive in the island on Monday to provide an outreach programme for children and adults with learning and sensory difficulties.
Pauline Allen and Phil Stickland from the The Sound Learning Centre, in London, will visit the island for a fifth time to provide pioneering treatments. Manx Mencap is again sponsoring their visit and paying for a group of about 12 people to receive treatment.
Self-funded spaces are filling fast but one or two places may still be available.
Pauline, the principal, and Phil, who is general manager, will be based at Centre 21, in Homefield Road, Douglas.
The treatment involves sound and light therapy to target the auditory and visual systems.
Auditory integration training involves listening to music that has been specially modified and filtered through an electronic device, the Audiokinetron.
Meanwhile, lightwave stimulation uses low intensity, pulsed, coloured light to rebalance the sympathetic and parasympathetic sides of the autonomic nervous system.
Since their first visit to the island in 2009, the specialists have treated more than 40 people.
