Multiple sclerosis (MS) can be a highly destabilizing diagnosis to receive, leading a person to question their identity, yearn for explanations, and reorient their worldview.
“We have this belief in our society that we are in control of our lives. Unfortunately, MS really rips that away,” says Jordyn Anderson, PsyD, a neuropsychologist and Assistant Professor of Neurology at the Icahn School of Medicine at Mount Sinai.
Psychotherapy can help patients move through the diagnosis acceptance process and provide guidance in navigating a life filled with uncertainties in dealing with this chronic disease, and, ultimately, living a meaningful life.
Dr. Anderson is the sole clinical psychologist at Mount Sinai’s Corinne Goldsmith Dickinson Center for Multiple Sclerosis, where she is developing interventions for people living with MS.
People living with MS face a number of challenges that may lead them to consult with a licensed psychologist, beginning with how to incorporate their diagnosis into their sense of self, along with how to manage anxiety, depression, sleep disruption, and optimizing health behaviors such as physical activity, smoking, and diet.
“Anxiety and tolerating the uncertainty that MS presents in your life, not only from a ‘what’s going to happen’ perspective, but also with navigating the medical system, is very hard,” she says. “You are dropped into a world where insurance might determine your safety, where bureaucracy might be getting in the way of whether or not you are able to receive medication.”
A clinical psychologist specializing in MS can ease the stressors associated with adjusting to the reality of living with the disease. Dr. Anderson works with patients on magnifying their internal locus of control, focusing on what they can do to help themselves while accepting this reality.
“I focus a lot on acceptance,” she says. “A patient may never be thrilled with an MS diagnosis, but accepting this reality as part of one’s life, figuring out how to live with it rather than in defiance, can be freeing.”
Grief can be a prominent factor in people’s symptoms. “Grief is not just about death,” Dr. Anderson says. “Grief is about the loss of anything. You might be grieving your sense of self as a particular label. Or maybe you are grieving your future in some way, your beliefs for what you had in store for yourself.”
Framing it as a grief process that develops and changes with time can be a way to understand the diverse array of emotions that people face. In helping people adjust mentally to dealing with their MS, and thinking of how to get through certain lifestyle situations directly affected by the disease, a grieving process can be a significant part of acceptance.
Dr. Anderson came to Mount Sinai in 2020 on a two-year clinical neuropsychology fellowship in the MS Center’s neurocognitive clinic headed by James Sumowski, PhD, who focuses on identifying and treating cognitive deficits in people living with MS. In 2022, she became the Center’s first full-time psychologist providing therapy and behavioral health interventions for patients.
The waitlist for appointments indicates the demand and need for this kind of consultative service. In 2025, she began a psychology externship, employing graduate level students to help provide interventions in order to expand the clinical reach. Patients are usually referred to her by their neurologist, or through the MS Center’s Wellness Program, which offers guidance on prioritizing diet, exercise, and sleep that can help MS patients live healthier lives.
Another common issue for individuals with MS is insomnia. “There are a myriad of reasons insomnia is happening. Is there some sort of stressor that’s in the way?” says Dr. Anderson. She works with patients in identifying sources of sleep disruption, optimizing sleep hygiene, and developing relaxation strategies. Additionally, CBT-I (Cognitive Behavioral Theory for Insomnia), a treatment targeting difficulties with initiating and maintaining sleep, is sometimes recommended and can be transformative in restructuring sleep routines.
Dr. Anderson specialized in MS by chance. “I always wanted to do health, neuro, and rehab, and I was lucky to get the fellowship at the MS Center,” she recalls. “I absolutely loved it. I felt like I was able to focus and become an expert in something,”
She is inspired by working in a field of neurology and psychology imbued with optimism. “It’s an amazingly hopeful time for MS. The fact is that we have these really effective medications that they are consistently researching and we are, hopefully, finding new ones,” she says.
Dr. Anderson is also drawn to “the diversity of patients,” including the broad variety of symptoms among patients, their backgrounds, and their personal stressors that come together to create very individualized experiences of the disease.
“Every single person’s challenges are valid. I feel like I am always learning so much from my patients,” she says. “I am constantly challenged and have to flex different skills. I think I’m here for good.”
