Cognitive Impairments Cognitive impairments are any limitations in the ability to think or reason that affect a person's capacity to perform a task.
Cognitive impairments can be congenital or the result of a head injury, stroke, or disease.
Head injuries in particular can result in very localized damage, producing highly-specific problems. Many cognitive impairments are quite common, such as attention difficulties and dyslexia. Cognitive impairments are often less observable and well-defined than other types of impairments, so it is helpful to consult a doctor or learning specialist to help clarify the exact nature of the impairment. Used, for instance, in a medical setting to remind clinicians of necessary tests or interventions. Useful especially to people with memory impairments.
