Cognitive impairment problems can be caused by multiple sclerosis (MS) and may include difficulty with:

• Memory, especially short-term memory.
• Problem solving.
• Keeping attention on a mental task, such as a math calculation.
• Finding the right words to express yourself.

These problems are often quite mild early in the course of the disease, but they may get worse with time, depending on the location of tissue damage (MS lesions) in the brain. Neuropsychological tests may help identify specific problems. Side effects of medications used to relieve physical MS symptoms may cause cognitive problems.

Emotional problems may include:

• Depression, which is common in people with MS.
• Anxiety.
• Anger.
• Inappropriate cheerfulness (euphoria).
• Thoughts of suicide.

Treating your emotional problems is as important as treating other symptoms of MS. Family counseling and counseling by other people who have MS are both available. If you need help finding a counselor or support group, contact your doctor or the National Multiple Sclerosis Society.
