Diagnosing a Cognitive Impairment
Your physician will probably be the first person you'll discuss your symptoms with. They will refer you to a specialist who conducts tests to diagnose your condition. Typically, you will be referred to a psychologist or a neuropsychologist.
A neuropsychological evaluation is a reliable procedure specifically designed to assess cognitive functioning. It uses standardized tests to evaluate areas such as general intellectual ability, academic achievement, memory, language, spatial/perceptual abilities, conceptual reasoning, and emotional functioning.
There are a number of areas that such an evaluation will assess, including language, various types of memory, and visual skills. Tests that may be used include the Halstead- Reitan, Wechsler Scales, and the Luria Nebraska. The length of the test battery and the cost will vary depending on the extent of your symptoms.
If you suspect a cognitive impairment, it can be hard to take the step of seeking help. But remember, with proper diagnosis and intervention, you might be better able to manage your impairment. There are medical professionals, memory specialists, and/or medications to assist you. Don't let an undiagnosed cognitive impairment jeopardize your health, your relationships, your mobility, or your success at school or work.
