What types of behaviors do you see with MS patients in regards to dementia?

According to the National MS Society and the Dana Foundation, dementia is not a common symptom of multiple sclerosis (in fact it may be a red flag for a different diagnosis), but it can cause cognitive decline and mood instability. More than half of people diagnosed with MS may experience cognitive decline, according to the Dana Foundation. Cognitive change "refers to a range of high-level brain functions affected in 50% of people with MS, including the ability to learn and remember information, organize and problem-solve, focus attention and accurately perceive the environment." Emotional changes can be a reaction to the stresses of living with MS as well as the result of neurologic and immune changes. Bouts of depression, mood swings, irritability, and episodes of uncontrollable laughing and crying pose significant challenges for people with MS and their families. NMSS has excellent guides and materials on MS, caregiving, cognitive issues with MS, and finding support.

MS affects different people, differently. I have had patients who just lost vision....& it returned in a few days. Another comes to mind who would say all the time,
"I feel like an ice pick is going through my left eye"~She also had bad judgement. I believe she was cognitively impaired.
Been a medical professional A LONG TIME. The list goes on & on~I have not experienced 2 people with the same identical signs & symptoms. It varies person to person; dementia also presents differently.
Cognitive impairment can & can not go with MS.
