These issues include difficulty with memory, concentration, and problem solving, which many people refer to as “cog fog.” Memory loss is the most common mental change in people with multiple sclerosis (MS). It can occur at any time in the course of your MS. Even if you do not have physical signs of the disease, you may experience memory loss. Other factors, such as heat, stress, depression, and fatigue, can all contribute to memory problems.
Evidence suggests that memory problems associated with MS occur when lesions in multiple areas of the brain break down the transmission of nerve impulses responsible for the ability to remember. There are 2 types of memory-loss problems:
Recent memory:
Newly learned information, such as names of people you just met. It also includes things you are trying to remember for the future, like a telephone number or taking your medication. Recent memory is most often affected by MS.
Remote and procedural memory:
Information or a skill you learned a long time ago (eg, tying your shoelaces). This type of memory is not as likely to be affected by MS. Other factors such as heat, stress, depression, and fatigue can all contribute to memory problems.
Our Symptom Tracker makes talking to your healthcare provider easier.
You may want to be tested if you think you are experiencing memory loss. Talk with your healthcare provider about your symptoms and possible treatment options.
