Many individuals with multiple sclerosis (MS) will begin to notice the subtle cognitive changes typically associated with MS.  Individuals may report being more forgetful, unable to multitask as well as they used to, or feeling as if their thinking is slowed down.  Some may say, “I feel as if I am just not functioning on all four cylinders.”  They would be right. In fact, anywhere from 43% to 70% of individuals with MS suffer from some degree of cognitive dysfunction.  Most often, it is slowed thinking or problems with memory that are most noticeable and known to have the greatest effect on day-to-day functioning – this can be anything from preparing a meal for the family, doing everyday tasks, or even successfully doing one’s work.

When cognitive symptoms begin to interfere with such tasks and one’s overall quality of life, it is best to consider speaking to your neurologist about undergoing a neuropsychological evaluation.  A comprehensive neuropsychological evaluation consists of a battery of cognitive tests assessing language, attention, verbal and visual memory, processing speed/working memory, and executive functions (e.g., planning, organization, reasoning) as well as a full psychological evaluation assessing things like mood, anxiety, sleep, and fatigue.  These latter factors are known to also play a large role in cognition and are, fortunately, reversible with effective treatment.  For instance, while slowed thinking is common in MS, consistent poor sleep or depression can also lead to cognitive disturbances during the day and further compound existing cognitive disturbances. Thus, proper identification of one’s current cognitive abilities as well as factors that can affect cognition (such as poor sleep) is the first step in taking appropriate steps in managing any cognitive changes associated with MS.

So, when is a neuropsychological evaluation right for you? Again, if you are noticing changes and feeling that they are beginning to impact your daily functioning and quality of life, you should consider having a neuropsychological evaluation.  This is particularly important if you are employed and/or are a student and can benefit from some recommendations and strategies as to how best maintain your job or schooling, while working to your strengths and minimizing reliance on your weaknesses. Formal documentation of such cognitive difficulties can also assist with obtaining appropriate accommodations at work or school.  Finally, some recommend completing a brief neuropsychological battery such as the Minimal Assessment of Cognitive Functioning in Multiple Sclerosis (MACFIMS) at the onset of one’s illness so that there is a baseline to which patients can better monitor the progression of their illness and cognitive changes associated with such.
