A shocking diagnosis
When the abnormal sensations in her legs didn't subside, Sigler asked her parents to take her to the emergency department, where a neurologist ordered a lumbar puncture (spinal tap), a diagnostic test that when used to evaluate for multiple sclerosis (MS) involves removing and analyzing a sample of cerebrospinal fluid (CSF). She also had an MRI and a CT scan to detect disease-related changes in the brain and spinal cord.
Doctors may also order tests called evoked potentials, which record and measure electrical impulses that travel through specific sensory pathways of the nervous system in response to stimuli. Of the three types of evoked potential tests—visual, auditory, and sensory—the visual test is considered the most useful because up to 90 percent of patients with MS have slowed responses on this test.
"MS is very variable, and no two patients are alike," says Patricia K. Coyle, MD, FAAN, professor of neurology and acting chair of clinical affairs at Stony Brook University in Stony Brook, NY, and director of the MS Comprehensive Care Center at Stony Brook University Medical Center. "But bladder problems, numbness, and tingling sensations are common symptoms."
When her lumbar puncture and MRI results came back consistent with MS, Sigler was stunned. MS, a chronic autoimmune disease of the central nervous system, damages the myelin sheath, the material that surrounds and protects nerve cells, slowing down or blocking messages between the brain and the body. Sigler, who was diagnosed with relapsing-remitting MS, a form of the disease characterized by symptom flare-ups followed by periods of recovery, says she had trouble accepting the diagnosis. "I was in denial. I wanted to live in a fantasy world where I could pretend I didn't have this disease," she recalls.
She felt confused, isolated, and depressed, and she worried that she would eventually be wheelchair-bound. No amount of reassurance from her doctor that she could live a full life helped. And she rebelled. Although she was prescribed an injectable drug, she confesses she wasn't always consistent with her medication regimen. "I didn't want the responsibility of being on a daily medication, so I stopped for several years, and for a while I was symptom free. In hindsight, I wish I had stayed on the medication and followed my doctor's orders."
When on set filming, Sigler often had to sit for five minutes between takes to recharge. If she experienced any muscle weakness or numbness, she would blame her limitations on a bad back. She admits that keeping the disease a secret led to depression.
Although MS is unpredictable and can cause disability for some people, it is highly treatable, says Barbara S. Giesser, MD, FAAN, clinical director of the MS program at the David Geffen School of Medicine at UCLA and co-author of Navigating Life with Multiple Sclerosis. "Treatment for MS involves drugs that reduce ongoing nerve damage and inflammation plus other medications, rehabilitative strategies, and lifestyle modifications that improve symptoms and enhance everyday function and quality of life," she says.
Sigler's case is not an anomaly: Most people are diagnosed in their 20s and 30s, says Dr. Giesser. And two to three times more women develop MS than men, a sex difference that has increased over the past 50 years, according to the National MS Society. While researchers don't know exactly why women are disproportionately affected by MS, Dr. Coyle notes that women are more likely to be affected by other autoimmune diseases, as well, including lupus and rheumatoid arthritis. Of the 50 million Americans living with an autoimmune disease, more than 75 percent are women.
Long-held secret
Sigler was reluctant to reveal her diagnosis, fearing she might lose friends or acting jobs. Her suspicions were confirmed when an industry professional advised her to keep her diagnosis a secret. "I was told having MS would limit my acting career and people wouldn't hire me," Sigler says. "And because I was so young, I took that advice to heart." Only her family and a few close friends—including The Sopranos cast members Edie Falco and the late James Gandolfini, who she says was very protective of her—knew her secret.
When The Sopranos ended its eight-year run in 2007, Sigler continued to work as an actor, appearing in television shows such as Entourage, Ugly Betty, and Guys with Kids. Despite often feeling fatigued and stiff and continuing to keep her secret, she says staying busy and being employed was comforting.
During this time, her symptoms began to flare up, coinciding with the end of her two-year marriage to her agent and first husband, A.J. DiScala, in 2006. Sigler is sure the stress of her divorce contributed to the flare-ups. "My right side became weak, and I began to have balance and bladder problems," she says.
Ready to go public
In 2012, Sigler found love again when she began dating baseball player Cutter Dykstra. The two were engaged in January 2013 and announced the next month that they were expecting a baby. Their son, Beau, was born in August of that year, and Sigler and Dykstra were married in January 2016. It was the birth of her son that prompted Sigler to discuss her diagnosis openly. "I didn't want to ask my son in the future to help keep my disease a secret," she says.
Sigler says she has been humbled by the expressions of goodwill she received after revealing her diagnosis and surprised by how therapeutic the experience has been. She received supportive messages from fans on social media, as well as from friends and family members who texted and called, offering encouragement and understanding. "I think I made my life harder by not letting people in," she says. "When I got to a place where I could be honest with others and feel more comfortable asking for help, life got easier."
It also influenced her decision to become an advocate for the MS community. In January 2016, she partnered with the pharmaceutical company Biogen and Self magazine for the Reimagine MySelf campaign, which features a blog dedicated to helping women navigate their daily lives while also dealing with any complications of the disease. Sigler says she also wanted to set a good example for Beau about honesty and transparency.
"With the blog, I can be honest and talk about how MS impacts all aspects of my life, how I balance caring for my son with having MS, and how I make my relationship with my husband, Cutter, a priority. The blog also gives me a platform to advocate for MS and become more involved in the MS community."
In May 2017, Sigler will be awarded the 2017 Medal of Hope at the 24th Annual Race to Erase MS Gala, hosted by founder Nancy Davis, a Los Angeles mother of five who was diagnosed with MS in 1991 at the age of 33. "Coming forward with my diagnosis has been empowering," Sigler says.
Although Sigler chose to reveal her disease, many people with MS and other neurologic conditions keep silent, fearing that being open about their condition may affect their careers. Disclosing MS to your employer is an individual decision, says Dr. Coyle, who encourages her patients to review their work environment carefully to see if any limitations need to be addressed or if any accommodations could help them do their job better.
"Do you work in a nurturing or hostile environment? How has your workplace dealt with other employees who have disclosed their medical conditions?" says Dr. Coyle. "By law, you aren't required to disclose your condition, but if you believe that disclosing it will make it easier for you to take off time for doctor's appointments or to cut back on a demanding schedule, then it might be worth it to talk with your employer."
