Entitlement to the care component or mobility component of disability living allowance is not linked to particular disabling conditions, but on the extent to which a severely disabled person has personal care needs and/or walking difficulties as a result of their disability.
People with spasmodic torticollis can qualify for the allowance if they satisfy the rules which govern entitlement most of the time. Advice is available in the Disability Handbook to decision makers on the variability of care and mobility needs that can result from this condition, and other forms of dystonia.
The Disability Handbook is maintained and updated on an ongoing basis by medical advisors in the health, work and wellbeing directorate and is available on the DWP website:
