The multiplicity of disability definitions can be attributed to the heterogeneity of disability, its multifactoral nature, and its effects across the life span. Of particular concern to the social work profession are those persons with neurocognitive disabilities. Neurocognitive disabilities are ones where a problem with the brain or neural pathways causes a condition (or conditions) that impairs learning or mental/physical functioning or both. Some examples are intellectual disabilities, autism spectrum disorders, and savant syndrome. Neurocognitive disabilities are the most difficult to diagnose often times because of their invisibility. Providing services for people with neurocognitive disabilities is very difficult, and people with these disabilities are among the most vulnerable populations in today's society. This entry discusses neurocognitive disabilities and current and future trends in social work disability practice.

Hearing loss is common, with approximately 17% of the population reporting some degree of a hearing deficit. Hearing loss has profound impacts on health literacy, health information accessibility, and learning. Much of existing health information is inaccessible. This is largely due to the lack of focus on tailoring the messages to the needs of deaf and hard of hearing (DHH) individuals with hearing loss. DHH individuals struggle with a variety of health knowledge gaps and health disparities. This demonstrates the importance of providing tailored and accessible health information for this population. While hearing loss is heterogeneous, there are still overlapping principles that can benefit everyone. Through adaptation, DHH individuals become visual learners, thus increasing the demand for appropriate visual medical aids. The development of health information and materials suitable for visual learners will likely impact not only DHH individuals, but will also be applicable for the general population. The principles of social justice and universal design behoove health message designers to ensure that their health information is not only accessible, but also equitable. Wise application of technology, health literacy, and information learning principles, along with creative use of social media, peer exchanges, and community health workers, can help mitigate much of the health information gaps that exist among DHH individuals.
