Unveiling the Invisible: Mental Health Disorders as Early Indicators of Multiple Sclerosis
Mysterious Nature of Multiple Sclerosis
Multiple sclerosis (MS) is an autoimmune disease that, owing to its array of diverse symptoms, often evades early diagnosis as it can be mistaken for other illnesses. The disease arises when the immune system turns against the body, attacking the myelin sheath that protects neurons. This disruptive assault on the body’s communication system leads to a myriad of complications such as weakness, numbness, vision loss, mobility limitations, and, in severe cases, paralysis. As per the World Health Organization, approximately 2.8 million people worldwide are grappling with this chronic nervous system disease that often leads to disability.
Surge in MS Cases in Russia
In Russia, a significant increase in MS patients has been observed, with nearly seven thousand patients diagnosed in 2022, marking an 18% increase from 2020. Early diagnosis of MS is crucial to initiate treatment and slow down the disease’s progression. Traditionally, clinical manifestations were thought to begin with the first episode of demyelination, such as vision problems.
A New Perspective on MS Onset
However, a new perspective on the onset of MS has been proposed by neurologists from the University of British Columbia (Canada). They suggest that there exists a preceding period when the disease manifests indirectly, not through classic symptoms. This phase, known as the prodromal phase, was the focus of their scientific work published in the journal of the American Academy of Neurology, Neurology.
Analyzing Mental States and Disorders
The researchers collaborated with colleagues from other Canadian universities to analyze the medical records of 6863 MS patients from their region. Their focus was on the prevalence of mental states and disorders, including depression, anxiety, bipolar disorder, and schizophrenia, five years before the patients displayed classic, medically recognized MS symptoms. The findings were then compared with data from a control group of 31,865 patients without autoimmune pathology.
Insights from the Study
The study revealed that MS patients experienced mental health issues almost twice as frequently (28%) as the general population (14.9%). A higher percentage of people from the first group also sought medical help for mental symptoms, including visits to therapists and psychiatrists, prescription medications, and hospitalizations. The gap between the two groups grew larger each year of the five years preceding the clinical manifestations of the disease, with mental symptoms peaking in the last 12 months before the onset of MS.
Implications of the Findings
While these mental states do not predict MS, the researchers stress that they could be part of the prodromal phase puzzle and a potential warning sign combined with other factors. This groundbreaking study builds on previous work by the neurologists, who found that fatigue, sleep disorders, irritable bowel syndrome, anemia, and pain could also be part of the prodromal period before the onset of MS.
A Ray of Hope: Improved Treatment Options
The significance of these findings is heightened by the fact that treatment options for MS, particularly in the early stages, have significantly improved in recent years. In the U.S., for instance, a “reverse vaccine” has been developed to suppress the self-destructive immune response. The first phase of clinical trials is currently underway to assess the safety of this new type of therapy in treating patients with MS.
