Telecommunications technology in cognitive rehabilitation.

Cognitive disorders are a common long-term consequence of many forms of acquired neurological damage of different aetiology. The already high prevalence of diseases causing cognitive deficits (in particular stroke) is expected to increase in the near future, leading to a greater need for cognitive rehabilitation. The impact of cognitive impairment on daily functioning may be even greater than that of physical limitations in affected patients, contributing to the high cost of brain disorders. New technologies, including telerehabilitation, may provide an effective response to this challenge, allowing increased access to rehabilitation services as well as reduced care costs for individuals needing cognitive rehabilitation.
